Daughter board for CP/M Turbo7
Here is the VDP Daughter for CP/M Turbo7 card.
It can be installed as the below.
After some of address decoding and some signal processing..
It is working as the SG3000 and run some game as under.
Andthen there is some techinical issue.
CP/M tubo7 looks not handle IORQ properly. so, I've updated CP/M turbo7 and added the signal on the CPLD spare pin.
After start run, it looks not stable.
I'm checking where is the problem came from, CPU, or signal or TTL?
I'm working on it.
Keep watching.. :)
** Solved stability issue.
I fixed it and works stable now.
It keep running more two 24 hours.
I'm considering to put a Sound chip same as SG3000 and Joyport pins..
Then board buyer could play games as the SG3000.
Maybe it would make it more fun..
** Just added Sound chip.
** Added another interesting picture.
But, don't expect too much.
It doesn't means that I made MSX computer..
The board have different structure unlike MSX and I can't run ROM of MSX.
But, you can make your own coded to make it run on MSX computer and this board too.
This is the maximum ability of this board.
If you want MSX board, please wait some more weeks to complete the board.
Thanks;
Ian Kim
** I've tested another games of SG-3000 and all works.
Some of game may not work properly.
Please aware it.
Thank you!
