  • Love the project but I'm having some issues getting it working. I'm wondering it its a PAL vs NTSC issue. I using SN74LS273N, GAL20V8B-15LP and W27C020-70. I used the jed file in the GAL folder to program the lattice chip. I put sixteen 16K prg games in the prg folder and used magic desk to make a 256K bin file. I set the jumpers on the back to match the 020 chip. When I plug it in and power on the system its Just a black screen. My C16 works with the tutor cartridge so I know its working. I'm not sure if it would be the lattice chip configuration or the magic desk file that is causing the issue. I have tired with and without the 100nf (104) ceramic capacitors. I tested the 74LS273 with the TL866 logic test and everything passes. Thoughts? Ideas?
