Extracting files from Tatung Einstein disk images
Kevin Edwards got hold of some 3" disks containing source code to various old commercial games and once they were imaged with a high quality process (a Kryoflux) it was time to write some tooling to get the files out of the corresponding DSK file.

A quick primer on floppy disks
I've always been fascinated by floppy disks from the crazy stories of Steve Wozniak designing the Disk II controller using a handful of logic chips and carefully-timed software to the amazing tricks to create - and break - copy protection recently popularised by 4am.

Mac OS System 9 on Windows
I'm often digging into old bitmap font and UX design out of curiosity - and someday hope to revive a lot of these fonts in more modern formats using a pipeline similar to that for ZX Origins so we can get all the usable fonts, screenshots etc. out of them.

Notes from my Spectrum +3 manual
I've recently been working on a full HTML5 conversion of the Sinclair Spectrum +3 manual with full canvas-drawn screenshots and diagrams for smooth scaling/high res displays as well as some close font matching and layout as well as cross-reference links all over the place.

Revisiting my BBC Micro - display, speech & more
It's been a while since I blogged about Revitalizing my BBC Micro. In that time, I've performed a few upgrades readers might find interesting.
As useful as the tiny Amstrad CRT was, I wanted something bigger, brighter, and sharper. LCD is terrible for retro systems with blurry scaling attempting to draw images designed to take advantage of CRTs. Emulator authors spend significant effort trying to mimic CRT effects for an authentic retro feel - but the best option is to use a CRT.

Typography in bits: For a few pixels more
Examining the system fonts of the TRS-80 Color Computer, Dragon, Tatung Einstein, Commodore 128, Texas Instruments TI-99/4A, and Oric Atmos.

Revitalizing a BBC Micro
My "Beeb" is in good condition and works well, but the case screws have long since disappeared (a common theme in my collection), and it needed a good clean. These older mechanical keyboards attract dust and dirt...

Typography in bits: Other English micros
Examining the system fonts of the Sinclair QL, Memotech MTX512, Amstrad PCW, Acorn Archimedes and SAM Coupé.

Typography in 16-bits: System fonts
A look at the system fonts of 16-bit machines including the IBM CGA & VGA Adapters, Apple Macintosh, Commodore Amiga, and Atari ST.

Typography in 8 bits: System fonts
Examining the system fonts of the Commodore PET, Apple ][, Atari 400/800, Acorn BBC Micro, Sinclair ZX Spectrum, Commodore 64, Amstrad CPC, and MSX.

Origins of a love affair
From an earliest memory of a cream colored box emblazoned with letters, mostly black – some red, came an owl proclaiming allegiance to the BBC.

The Xerox Alto mono-spaced font rises again
Computing 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).

How did I get started in software development?
Ken Egozi tagged me with the latest meme and this time it’s at least relevant :)

Adding depth to my programming ability
I remember gazing at the screen of Acornsoft’s Elite in my childhood wondering what the code behind those 3D images looked like.
How did they rotate like that? How did it know which lines to hide? And more importantly where I can get a good price for this cargo hold of radio-actives and platinum?
