Typography in 16-bits: System fonts

With the 8-bit system fonts post being so popular I just had to jump right in and look at the system fonts available on the 16-bit machines!

IBM CGA system font in low resolution IBM CGA system font in medium resolution
The IBM PC’s first color graphics card was known as the Color Graphics Adapter.

Unusual characteristics

  • Mix of serifs and non-serifs depending on space
  • Off centre ‘|+:’
  • Squished ‘Q’ to avoid using descender
  • Wide ‘0’
  • Bubbly ‘!’
  • Inconsistent ‘t’ point and lack of serif on ‘j’

Rationale

The large bold letters work well on the low-resolution displays at the time and many of the quirky were unlikely particularly noticeable there.

Influences

Unknown.

Apple Macintosh 'Chicago' system font
Apple’s second attempt at a GUI (after the Lisa) was the Macintosh. The system font was called Chicago initially as a bitmap font which was replaced with a scalable TrueType version. With Mac OS 8 it was replaced with the similar Charcoal typeface and then dropped entirely in Mac OS X which uses Lucida Grande for the UI.

This font was dusted off again in 2001 and with a few minor tweaks became the system font of the iPod (classic & mini) until the higher resolution color display model.

Unusual characteristics

  • Proportional letters not fixed-width
  • Some symbols are not bold at all ‘#%”/\*@^`’
  • Lovely flourish on ‘&’
  • Curve on ‘a’ actually touches the lower bowl
  • Designed specifically to avoid diagonal strokes (jaggies) on the Mac’s low-res screen

Rationale

The high-resolution display let the designers really pay attention to detail and even though it was a 1-bit monochrome display it really looks beautiful for the time. It was little wonder that when Jobs went to NeXT they went with incredibly high-resolution monochrome displays again (at least initially and with 2-bit grayscale).

Influences

It’s unlikely they were digital.

Commodore Amiga 1.x 'Topaz' system font in low & high resolutions Commodore Amiga 1.x 'Topaz' system font in medium-resolution

The Amiga started with ex-Atari engineers desperate to design a 16-bit machine. It would eventually be purchased by Commodore and offer incredible graphics and sound that put Macs and PCs of the time to shame. Despite shipping with many fonts and supporting proportional text the default system font was a traditional fixed-width font called Topaz/8.

Unusual characteristics

  • As well as some letters touching some symbols such as ‘\/’ touched horizontally allowing nice ASCII art
  • Unusual lower-case ‘g’ somewhere between double and single story
  • Unusual almost comic-like ‘!’
  • Some non-bold pixels for flourishes on ‘t&’
  • Pixels missing on some curves ‘aS’ especially obvious in low resolution
  • Over-extended ‘r’ looks odd in any resolution
  • Alternate Topaz/9e – 10×9 (2 for descenders) – modified some glyphs like ‘g’ and available from Preferences as Text 60

Rationale

The Workbench booted in white-on-blue (shown) and was intended for use either with their own Commodore monitors or home TVs. Despite the choice of a serif font it worked quite well on these displays although interlace was quite unusable without specialized displays.

Influences

Very similar to the IBM CGA system font, very likely to be derived from there.

Technical

The Amiga shipped with it’s own font editor called ‘Fed’ found on the Workbench Extras disk in the Tools folder.

Commodore Amiga 2.x 'Topaz' system font in low & resolutions Commodore Amiga 2.x 'Topaz' system font in medium resolution

Commodore’s update to the Amiga saw all sorts of changes in the ROM and Workbench for the GUI including some revisions to the font and the ability to change what font the workbench used.

Unusual characteristics

  • Over-extended top of ‘1’
  • Open elements on ‘%@’
  • Messy ‘Q’ is hard to distinguish
  • Alternate Topaz/9e – 10×9 (2 for descenders) – modified some glyphs like ‘g’ and available from Preferences as Text 60

Rationale

The Workbench booted in black-on-grey (shown) and the new font looked a lot more friendly as well as being a more legible choice for home TVs.

Influences

Obvious modification of the prior 1.x font to remove serifs and improve legibility.

Technical

WBScreen allowed you to choose which font to display in Workbench including some of the proportional fonts included.

Atari ST system font in low resolution Atari ST system font in medium resolution

The Atari ST was Atari’s answer to the Commodore Amiga after they failed to purchase back the talent and technology. The machine’s GUI was based on GEM from Digital Research.

Unusual characteristics

  • Descenders are cut very short on ‘pq’ despite ‘gy’ not following this style
  • Inconsistent positioning between ‘,’ and ‘;’
  • Ugly braces ‘()’ from the 8-bit font retained

Rationale

The font was very clear and worked well in both square pixel (low resolution) and rectangular pixel (medium resolution) modes.

Influences

Almost identical to the Atari 8-bit font but with the capital letters, symbols and numbers extended a pixel higher (inverse symmetry was no longer a concern) and more consistent/cleaner lower-case letters ‘sj’.

Technical

It is possible to change the system fonts used by the GEM desktop using the ST Font Loader.

Atari ST high-res system font

Unusual characteristics

  • Very tall letters – some glyphs 14 pixels high but still only 6-7 pixels wide
  • Avoids every trace of a serif except usual ‘Iil’ monospace hack
  • Short descenders on ‘pq’ still
  • Inconsistent choices for ‘c’ and ‘R’ and ‘w’

Rationale

Given that this screen mode was only available on high-resolution monitors it is very rectangular and failed to really take advantage of the unique situation in which it would be used.

Influences

Very likely based on the medium resolution font with some redrawing.

VGA DOS system font

Unusual characteristics

  • Very tall letters – some glyphs 14 pixels high but still only 6-7 pixels wide
  • Top bar of ‘T’ is two pixels thick
  • Too-high double quotes ‘”‘ also styled inconsistently
  • Another bubbly ‘!’ like the Amiga’s Topaz 1
  • Inconsistent sizing between ‘,’ and ‘;’
  • Very large ‘$’ even bigger than the capital ‘S’

Rationale

A reasonably nice serif font that gave a serious look if somewhat inconsistent in places.

Influences

Almost certainly based on the original CGA font.

Technical

Can be overridden by tools like fontedit.com.

Typography in 8 bits: System fonts

My love of typography originated in the 80’s with the golden years of 8-bit home computing and their 8×8 pixel mono-spaced fonts on low-resolution displays.

It’s quite easy to find bitmap copies of these fonts and also scalable traced TTF versions but there’s very little discussion about the fonts themselves. Let’s remedy that by firing up some emulators and investigating the glyphs.

For more system font analysis read the sequel Typography in 16-bits: System fonts.

Commodore PET

Commodore’s first business machine was the PET which came with a built-in monitor and a full character set unlike other machines at the time.

Unusual characteristics

  • Primarily sans-serif but serifs present on ‘BDJa’
  • Slightly stylized ‘£’

Rationale

The font is good choice for the original PET and its original monitor. It was unfortunately also used on the Vic-20 despite having half the screen resolution where it made a poor choice.

Influences

While not visibly influenced from anything else an almost direct rip of this font appears to have been used in the Apple Lisa debugger.

Apple ][ system font

Apple's first professionally built computer was the Apple ][ which from rev 7 onwards added lower-case letters.

Unusual characteristics

  • Uppercase letters can touch descenders on the line above as the full height is used
  • Only first 7 columns per glyph otherwise would have been 35×24 text
  • Vertical stems for ‘[]{}’ are 2 pixels wide (bold)
  • Very small slashes ‘/\’
  • Upper-case is consistent although ‘A’ is very angular, ‘G’ unpronounced
  • Lower-case less consistent – ‘gf’ has soft curves, ‘mw’ square, ‘nhr’ ignore curve of ‘u’
  • Numbers – unusual ‘3’ but ’96’ over-extend

Rationale

The font is well suited to the default high-contrast white-on-black (often green-on-black) given the machine was intended for use on their own monitors.

Influences

The upper-case, numbers and symbols were copied from the Signetics 64 × 8 × 5 character generator 2513 chip used in the Apple I and II in revision 0 to 6.

The later Texas Instruments TMS9918 Video Controller Chip used on Sega, Nintendo, Colecovision and TI/99 machines re-used this font with only a couple of pixels changed.

Technical

Changing the font requires replacing the 2 KB 2716 pinout ROM with your own EPROM or alternate ROM.

Atari 8-bit system font

Atari’s entry into the home computing market put out some very capable machines with all sorts of hardware tricks (the creative geniuses behind it would go on to form Amiga). The same font was used on all Atari 8-bit models from the original 400/800 to the XL and XE models in the late 80’s.

Unusual characteristics

  • 6 pixels uppercase causes some vertical imbalance especially on ‘9’
  • Braces are overly bold being 3 pixels wide.
  • Less than and greater than symbols are too tall.
  • ‘MWw’ make great use of width to nice effect
  • Bar on ‘G’ too low, ‘U’ overtly square, ‘X’ very blocky, ‘S’ does not extend enough

Rationale

The machine boots in a low-contrast blue-on-blue and is designed for use with TV’s which explains some of the odd characteristics above like the square U to distinguish it from the V. It is likely the 6-pixel choice is to allow the letters to be centered when using inverse letter mode.

Influences

Adapted from Atari’s arcade font quite likely by Lyle Rains and/or Susan McBride.

Technical

One byte per row, 8 sequential bytes making one glyph. You can reprogram this by poking address 756 with the page number of the new font (default of 226 for ROM location 0xE000).

BBC Micro mode 1 system font

The Beeb, as it was affectionately known, has its own font which could display in three different modes – one wider and one narrower but many users might not recognize it all as it booted into ‘Mode 7′ utilizing a Videotex chip (used in the UK for text-on-TV and travel agents as well as in France for Minitel) that had a different font of its own.

Unusual characteristics

  • Drops bold in tight spaces e.g ‘$&@’
  • Outlines the tail on the ‘Q’ to make it much clearer
  • Unique and beautiful ‘*’
  • Does not extend low bar on ‘e’ as much as expected and ‘f’ seems to wide
  • Vertically squished ‘?’
  • Style of single-quote ‘ is inconsistent with comma

Rationale

The machine generally shipped with good quality monitors and the combination of high-contrast colors and this bold font made it very readable indeed.

Influences

It’s quite likely it was influenced by the Atari 8-bit font but with larger capitals and ascenders and a much more consistent look.

Technical

The system font is stored at 0xC00-0xC2FF with each character being represented by 8 sequential bytes (left pixel is high bit).
You can replace the font used by system text routine OSWRCH (0xFFEE) using the VDU command 23 followed by the ascii code and then 8 rows of data, e.g.

VDU 23,65,11,22,33,44,55,66,77,88

Sinclair ZX Spectrum system font

Sinclair’s successor to the ZX81 added color and lower-case letters – again preserving the upper-case and numbers from it’s predecessor but finally mapping them to ASCII. This font was re-used on Jupiter Ace and Timex machines but the ZX Spectrum was the most popular.

Unusual characteristics

  • 6 pixels uppercase leaves many unevenly balanced ‘BEFS’ and ‘X’ with ugly 2×2 center
  • Full stop is 2×2 pixels (bold) but colon, semi-colon and comma are not
  • Capital ‘MW’ are very slight with latter hard to distinguish from ‘V’
  • Uneven styling ‘c’ omits curves, ‘e’ is soft ‘g’ is not, ‘f’ and ‘k’ are thin
  • Only the copyright symbol uses to the top row of pixels

Rationale

While the machine has a default high-contrast scheme the video output was poor because of the quality of the RF modulator and home TVs it was connected to. It looks like the designer decided to increase spacing between letters after the ZX80 from one to two pixels which greatly limited what could be done with the letters themselves. This was likely done for the same reasons it was done on the Atari 8-bit – namely to allow the letters to be centered when using inverse text modes.

Influences

Sinclair ZX81 (no lower case), ZX80 (7 pixels wide).

Technical

The system font is stored at 0x3D00-0x3FFF with each character being represented by 8 sequential bytes (left pixel is high bit). You can replace the system text routine (RST 10) by poking the new fonts memory address into the system memory map at 23606/23607 minus 256 bytes (the first 32 characters are non-printable, 32×8 = 256)

Commodore 64 system font

Commodore took to take their success with the PET and applied it to the home first with the VIC 20 and then later with the wildly successful Commodore 64.

Unusual characteristics

  • Inconsistent shapes/style across ‘147,&<>@Q’
  • 2×2 pixel of ‘.’ is not carried through to ‘;:!’
  • Ascenders not as tall as capital letters

Rationale

The bold font was essential for the low-quality TV’s Commodore were aiming at. The inconsistencies across the font may have been intentional to help make the letters look different (A vs 4, 1 vs I, 7 vs T) given the limitations of the displays or just poorly implemented (see below).

Influences

Lower-case is identical to the Atari 8-bit font and likely copied wholesale as they do not match the upper-case well. Symbols, numbers and upper-case are a bolded version of the PET font that looses the serifs and also could explain the odd reproductions of 1, 2, 7 & 4.

Amstrad CPC system font

Alan Sugar’s foray into the UK market came a little later than the other 8-bits in 1984 with the Amstrad CPC series.

Unusual characteristics

  • Full use of 7 pixels for upper and 1 pixel for lower means glyphs can touch
  • Serif choice is unusual and not consistently applied because of space constraints
  • ‘0’ is wider than would be expected (copied from CGA font)
  • Very distinctive curves on ‘CGOQ’
  • ‘X’ looks like a different style because of high mid-point

Rationale

Sugar wanted the machine to look more professional than other home computers at the time. The choice of a serif based font to look like PCs which also featured serifs (at a higher resolution) reflects that desire.

Influences

Very similar to the IBM CGA font with some adjustments (fixes) to the horizontal positioning of some symbols. Many characters completely identical and some bearing style similarities too (wider 0, X choosing one side to be longer than the other). Some other characters bear similarity to the BBC Micro (Q uses the same trick to keep it distinguished) and a number of symbols and lower-case letters being the same where serifs would not fit.

The Amstrad CPC manual shows the system font but is different in some areas. It is possible it is a transcription problem (z is shifted up one pixel, missing pixels on ’37PRz~’ and extra pixels on ‘#b’ ) although it could have been an earlier version from the designer as ‘rG?’ are subtly different.

Technical

Redefine using the Amstrad BASIC command SYMBOL that takes an ascii code and then 8 comma-separated values one-per-row in much the same way as the BBC with the VDU 23 command. SYMBOL AFTER must be set first e.g.

SYMBOL AFTER 32

MSX system font

The MSX differs from the other machines here in that it was a standard rather than a specific machine. It was very popular in Japan and did hit UK shores although I only knew a single person that had one apart from our school which had acquired several Yamaha models to control MIDI keyboards. Given the multiple manufacturers it’s not surprising that some models had slightly tweaked fonts but the one shown here seems to be the most popular.

Unusual characteristics

  • Full use of 7 pixels for upper and 1 pixel for lower means glyphs can touch
  • Only 5 pixels wide for the letters
  • Pixels touching on the curves of ‘db’ etc. look quite ugly
  • Very angular curves on ‘5’

Rationale

An unusual choice that feels very quirky.

Influences

Most likely influenced by the Apple ][e.

Technical

Unknown.

Mac users should try Cathode – a retro terminal emulator I helped add some of these fonts to.

Font hinting and instructing &#8211; a primer

Taking my bitmap font Envy Code B into the vector TrueType Envy Code R was a long process, the most difficult being hinting.

Bitmap v scalable fonts

Bitmap fonts are incredibly easy to make. Using a program like Softy or BitFonter you decide the size of your letters and start plotting pixels. You can see exactly how it will look because you draw every glyph (letter/symbol/number) in every size you want to support. This can obviously be very time consuming and doesn’t let you take full advantage of the resolution of the device and the capabilities it offers. A printer can handle in excess of 300 dpi while a display is typically 72 dpi (Mac) or 96 dpi (Windows) with LCD’s supporting sub-pixels due to the individual layout of the red-green and blue elements you can’t feasibly pre-plot every single combination and even if you could the file size would be rather large.

Rather than having specific set of pixels to turn on or off TrueType, OpenType and PostScript fonts contain a series of instructions that tell the computer the shape using a series of points, lines and curves. This means the computer can scale the glyph to the size that is required and then take full advantage of the device being rendered honoring the users preferences for anti-aliasing (smoothing using shades of grey), sub-pixel precision (smoothing using hints of red, green and blue to take advantage of the layout of colour elements in an LCD display), desired contrast and gamma settings etc.

Grid fitting

Such a scaled glyph won’t fit perfectly within a pixel grid and a small sizes and low resolution it can look awful. It is also necessary to ensure that the vertical part of the letter I (known as a stem) looks very similar to the stem of other letters at the same size – we don’t want some letters looking bold – and that the top of the letter o aligns nicely with the top of the i etc. (in most fonts). The glyphs themselves don’t know what is a stem, what should align with other glyphs etc.

Many renders include logic to try and improve un-hinted fonts such as the drop-out control in Windows through to the full auto-hinter in FreeType. If you’ve ever used free fonts from any of the numerous web sites around you’ve probably seen that it doesn’t get it right and it looks like this: Envy Code R unhinted

The first few versions of Envy Code R looked like that because to address this problem you need to learn a process called hinting, which let’s the designer give the renderer “hints” on how to choose the pixels.

Hinting

Font hinting started off as stem and edge identification so that glyphs would maintain the right proportions when sized and rendered on these low-DPI devices. It became apparent that a much more fine-grained level of control was required and so a stack-based byte-code language was developed as part of the TrueType specification to allow designers finer control in how points are adjusted to better take advantage of the display characteristics.

A TrueType font can contain extra blocks which describes, using a sequence of bytes that represent instructions and their arguments, the process by which to align the points and therefore make decisions about how best to fit the letter into the grid by retaining and adjusting various elements.

The important blocks are:

Block Name Description
fpgm Font program Run once when font first used to setup the tables.
gasp Grid-fitting and scan conversion Table specifying when to apply smoothing and grid-fitting based on size ranges.
prep Control value program Run every time the font needs to be drawn differently (e.g. change of size, changing anti-aliasing etc)
cvt Control value table Set of tables that can be used to specify various heights, widths, spacing, positions etc. that glyphs can relate to.

Each instruction (opcode) has a mnemonic that is representative of what it does and these are documented in Chapters 5 through 6 of the TrueType specification (along with much other useful relevant information). Actual per-glyph instructions are stored with each glyph outline in the glyp block.

Rasterizing & rendering

There are many different ways a TrueType font can end up on your screen with a lot of variants between how vendors chose to render the font and what options they expose to developers and users to fine-tune the experience.

  • Windows – User choice of 1-bit, 4-bit grey-scale anti-aliasing, ClearType, ClearType tuning and display DPI plus WPF and DirectWrite per-app options
  • Mac OS X – User choice of sub-pixel anti-aliasing strength and 1-bit cut-off plus per-app 1-bit option (e.g. Terminal)
  • Java – Per-application choice of 1-bit, grey-scale or sub-pixel rendering
  • Flash – Per-application choice of 1-bit or grey-scale
  • FreeType – Rendering library that exposes a number of runtime and compile-time settings

This is of course ignoring the other rendering engines out there such as the Adobe’s Photoshop, RiscOS, D-Type rendering engine, Font Fusion (used on BeOS) etc. and prior versions of those renderers listed above (Flash and Mac OS changed significantly). Getting it pixel-perfect on every combination is impossible but we can try :)

Tools

Instructing fonts is a painstaking process at the best of times and few people deal directly with the low-level instructions instead relying on tools, stem identification and higher-level languages to achieve the same result. Some tools that have support for hinting instructions are:

  • FontLab Studio 5
    Comprehensive font-production package for Windows and Mac that includes auto-hinting and it’s own higher-level link language that it can generate TrueType instructions from but it does not support viewing or modifying existing TrueType instructions and does not handle diagonals well. Rendering preview includes mono, grey-scale and ClearType. (Commercial $649)
  • Fontographer 4.1
    Rather dated font-production package for Windows and Mac. (Commercial $349)
  • FontForge
    Comprehensive font-production package that runs on X11 that includes auto-hinting and the ability to disassemble and edit existing TrueType instructions as well as debug them with stepping. Includes basic mono/grey-scale rendering options. (Open source)
  • Microsoft Visual TrueType
    Hinting instruction tool from Microsoft that uses it’s own higher-level VTT Talk language that compiles down to TrueType instructions that you can further edit. Includes a comprehensive set of preview rendering options but is not capable of disassembling existing instructions. (Commercial, free with signed licence agreement)
  • TTX
    Python scripts that can convert a font into an editable XML representation and back including disassembly and assembly of TrueType hinting instructions. (BSD)
  • TTIComp
    Command-line tool that provides an alternative C-like hinting language. (GPL)
  • Xgridfit
    FontForge scripts to provide an alternative XML-based hinting language. (GPL)
  • TrueTypeViewer
    Windows tool for displaying TrueType fonts and glyphs including debugging and descriptive disassembly of instructions. (GPL)
  • TTHMachine
    Real-time editing of hinting instruction mnemonics and observing their effects which is useful for learning. (Free, no longer supported)

The Xerox Alto mono-spaced font rises again

Preview of the AltoMono fontComputing history tells us of a mythical place where many of the innovations we take for granted today were either invented or refined to a working level at a single location known as the Xerox’s Palo-Alto Research Center (PARC).

These discoveries form the basis of much of the technology we use today and include the desktop metaphor, the graphical user interface, laser printers, object orientation and Ethernet.

Xerox manufactured a number of high-end machines including the 1973 Xerox Alto which, being GUI based, shipped with a number of proportional bitmapped fonts.

What is interesting to me however is the mono-spaced font used by the SWAT debugger (but not by the command prompts, they were proportional – ahead of their time!) and so, based on a screen-shot of SWAT, I thought it needed to live again!

I’ve had to make up a few of the symbols and letters that weren’t shown and filled out the symbols for the Windows 1252 Latin-1/ISO-8990-1 code-page and with the absence of any solid information online give it a name so here is Alto Mono!

Download Alto Mono (TrueType, Windows FON, BDF) (30 KB)

When using the TrueType version choose 6 point on Windows and 8 point on Mac OS X.

The Xerox manuals are also fun to browse though with such section headings as “Things the user doesn’t really need to know…” and “How to get out of trouble” and the comments about SWAT’s odd syntax and interface.

Don’t forget to check out my reproduction of the PalmOS system font. Not monospaced but very clear at small sizes – great for the Visual Studio output window ;-)
