CP/M OS is running on my Z80 card

Also Tested CPM 3.0 works!

With several Logic update on CPLD, I got finally working softcard.

I tested it and work as 1Mhz and 2Mhz.

My target is 7Mhz Z80 card. it would be very interesting steps.

The softcard used DMA and RDY and Z80 Wait for it's purpose of CPU.

Thanks MS for the idea of Z80 working on 6502 based Computer.

Now, I'm starting to put TMS9918 VDP and trying to make it work.

I hope to show some of working screen soon.

Thanks
