공지사항

Dear friends,


I've build PCB for Z80 CP/M card as below.

It is softcard compatible but can run upto 7Mhz.



User switch is for Normal and Turbo 7Mhz speed switching.

It is a prototype and will make better board for commercial purpose.

It works on my IIe and IIGS with limitation.

As you can see, It provide 40pin signals for Z80 DIY purpose.


Even Z80A runs on 7Mhz but, CPU rating changed to 20Mhz version maybe stabler. 


Thanks

Ian Kim
