공지사항

CP/M Turbo7





Dear friends,


Z80 turbo7 card is ready.

This card is compatible as MS Softcard hence, it runs MBASIC, GBASIC(It is my favorite Language). 

Z80 CPU speed could selected Normal or Fast mode.

Normal mode is same speed of MS Soft card and Fast mode make Z80 run to 7Mhz.

But, unfortunately even 7Mhz running Z80 but, APPLE II BUS can't give data to make satisfy for Z80, so the results is overall speed is about 1.6times faster then Normal Z80 card.

It is the Maximum speed which can run as MS Softcard compatible card.


I want it to run under APPLE IIGS for many of users who want to CP/M with APPLE IIGS.

It can run with Fast mode of APPLE IIGS. but CP/M card runs properly only on the 'Normal position'


It has 40pins AUX port for who like to make DIY board under Z80 CPU signals.

I hope to see any daughter board using the AUX port.


I used PLCC type CPLD who want to solder to pull some signal from CPLD for DIYer's board.

Original MS Softcard doesn't care the Signal for IO but, I added to care for the Z80 IORQ.

Hence, you can add your IO board and could control by Z80 ASM IO commands.

Hope to like this feature.


It is selling now for Korean fans first after this I will put some on eBay for international APPLE II fans.

Other English information will be followed after I put on eBay.


It doesn't work on APPLE ][ nor ][+. (I'm trying to make it run on ][ and ][+)

(** Now it start to work on APPLE ][+ and IIe non enhanced model but ][+ only work with Normal speed)

It runs on APPLE IIe enhanced, APPLE //e platinum and APPLE IIGS (With limitation).

APPLE IIe non enhanced model have to change the CPU to 65C02.


Others;

And I trying to make a sample daughter board with it.





Thanks
