The display controller chip seems to be a hard to source part if you want to stick to 80s components. Do you know what his recommendation would be for that piece?
- snarfy 7y agoIt looks like it would take about 20 chips. [1] [1] - https://eater.net/vga https://eater.net/vga
- rzzzt 7y agoNot an unreasonable choice, but it has to be noted that home computers of the era already used LSI/VLSI dedicated ICs for this purpose, condensing the functionality of these 20 chips into a single package.
- transitorykris 7y agoYes, that’s been a frustration for me. I’ve settled on the Motorola 6847 which requires a couple supporting chips. This is scavenging parts off eBay though, which seems to be a plentiful source. I’ll find out shortly whether any of them are actually good.
