It's actually four boards right now. 1 to replace the on-board dram with SRAM, one to interface the the 64's main memory, another to combine all the 64 roms into a single and the video board itself. I think it will be 4x4 inches when it is finished. The interface board and the video board are the only ones needed for the video in actuality, but the SRAM board for the c64 main memory is so I can eventually remove the VIC from the system all together.

The one I am using now is about that size or smaller and contains 10,000 gates. This is plenty for the Vic, but the cpu takes about 30,000. I just got in 15 of the 100,000 gate chips today and this should be just about enough to fit the entire c64 on(about the size of four stamps). > Are the sprites working now? Nope, but the char and bmp modes work all work in simulation. Bill Herd whipped out a quick and dirty sprite detection circuit that looks like it will work fine. I'm working on the interface board now... I need to eliminate the snow in the images from collisions of two unsynchronized busses. It has to be perfect if I have two CPU's running separately on both busses... A little snow on the screen is hardly noticeable, but a sure crash if the program losses on bit now and then.(maybe a crash now and then would make windows users feel at home machine :) ) > Good luck, > firstname.lastname@example.org > -Terry Raymond P.S.
