RE: [N8VEM-S100:695] Re: S-100 VDP prototype board PCBs are here
Initially I will most like be using peek/poke via MBASIC to see if the board
will do anything. For now I just want to see the board produce composite

I think I have most if not all of the parts for the VDP now.
I will most likely build the board this weekend.
What were you going to try as far as software?
I thought I'd try building a text driver for CP/M 3 first, though it would
be nice to see MSX running on an S-100 machine.
