공지사항

Dear friends,


Here is my second step for Appli-card Z80 with VDP Option board.


What is VDP Option board?

http://quick09.tistory.com/1375?category=552730



It starts to support the VDP Option board with 3.58Mhz Original speed.



Both of game are bigger than 32KB and it was hard to load on Z80 Turbo7 structure.

But, New board could support it without memory conflict problem.

Even Turbo speed support but the VDP chip can't run faster speed..


So, This project just remain turbo step control.

It would support some sort of clocks 3.58Mhz 7.16Mhz and 4Mhz, 8Mhz, 16Mhz...

I want the smooth step switching and VDP support even on high clock speed..


* Loading program is very similar the case of the Z80 Turbo7 card with VDP Option board..


Thank you very much;

Ian Kim
