    Been busy with work but I figured before I dash off I’d post the VDP-N core. Remind me to add some comments and stuff when I’m back :-)

    VDP1-N

    P.S. It needs an external 28.636mhz clock and an 8-bit (4-bit will actually do) R2R ladder.

    • Thanks for the great work.

      I’ll try and order some 28.6363Mhz crystals this week and give it a try out, but my normal component supplier doesn’t stock that value so I’ll have to try a different supplier. I’m pretty sure my new-ish PAL TV will accept NTSC.

      I’ve been waiting for parts for the last two weeks for my hardware implementation of the VDP-VGA and I’m still waiting :(

    • Where does one find the ASM OPcode information ?

      I downloaded the CDP-NTSC, and then found
      XS1 Assembly Language Manual
      but that only lists opcodes in a table format,
      and does not elaborate on what each does.

      The Data sheet is quite short, and has no opcode info at all.

      More docs must be hidden somewhere ?
