My next project, which is coming along nicely, is a Z80 SBC which is wire wrapped on a punch-down wire wrap prototype board. When it's done it should run MP/M II, a TCP/IP stack, and have a video controller supporting 80x24 text and a 320x200x8bit graphics mode. I've got a Bt453 palette controller which will complement the 256 colour graphics mode. It allows for a 24-bit palette, 8-bits per primary colour, and 75 ohm output which is compatible with VGA monitors. I'll use a 6845 to control the timing.

Can a 6845 generate the correct timing for a common VGA mode? I've been trying to find this out but can't find a good answer...
