# 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 you might find interesting…

## Display requirements

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 a true retro feel but the best option is just to use a CRT.

Most machines in the 80s and early 90s were designed for TV compatibility and so operated on a 15KHz horizontal refresh rate. The VGA CRT monitors people struggle to give away aren’t going to work as they start at 31.5KHz. British machines like mine also use the PAL (UK) video system rather than the NTSC (USA) system - ideally a display would handle both.

If you don’t need any VGA frequencies then a Sony PVM is the way to go. I also own an Amiga 1200 which is capable of some VGA modes so it would be nice to have one CRT for everything. Multi-sync monitors can do both but were rare back then and are even rarer now and the shipping cost on CRTs limits can be prohibitive.
