Hi friends,


PCPI Z80 card is one of Z80 card for CP/M.

This PCPI Z80plus have flexibility and faster Z80 run and have extension port for more fun functions.

But, this testing verion PCB has Missing one line....

Another fixed version will make soon.


* not tested BUS control on APPLE II side..

It have to test it but, I need 6502 source code for TMS9918 and Sound chip.

If someone have simple 6502 code for TMS9918 testing.. It would be nice demo sample for it.

Anyway, the Address of TMS9918 is same as SEGA1000.

Please help for good sample codes then I could test Z80 BUS devices direct on APPLE II(6502).


Thanks for waiting!

Regards;

Ian kim
