공지사항

Previous APMSX card is enough to run basic of MSX function 

but, I want some more enhanced function in it.

Now, I have new board.



What is different.

Used 144 pin CPLD as main controller.

I have more 32 IO pins now it is good enough.


I'm tring to add Konami 8K mapper and now it is working as below.

Now just support 128KB but, will extend it up to 256KB.


APMSX board have own 512KB SRAM and it support virtual slot for ROM cartridge emulation.

So I can load ROM file and can run without physical ROM cartridge. (Anyway, APMSX will have a external physical SLOT. so user still can use own cartridge)

And it accepted just 32KB ROM data but, now I can load 128KB ROM data and made it run properly.

The mapper is very different method unlike accessing APPLE II AUX memory .



I'm still having some more idea with APMSX but, I think, I should not expand too much on this board.

And It will support 256KB Konam 8K Mapper and little more? maybe.. then will be closed.


I will check the signal for External SLOT.

I've prepared for this but, have to test. 


Let's see the next what will happy with our APPLE II.
Thank you.
