← Progress this morning before the day job kicks in: I have an externally clocked VIC-20! Internal timing being driven my an ICE40 FPGA. It’s a couple cycles slow but getting there. Now to start on video signals. The math makes my brain hurt. More coffee #commodore #vicsrevenge
First time I've used this modeling software and was impressed. Working out NTSC Luminance timing logic is a big help after just a couple mins. 100Mhz clock on the FPGA so we can just count nanoseconds. Can export to Verilog after simulation. Most excellent #commodore #vicsrevenge →
