Z80 with TMS9918 start run
◆ Z80 Card / 2016. 4. 1. 23:23
I set the TMS9918 with VRAM and configure the IO Address.
The RAM using of APPLE II one not other one.
I did load the image ROM file by PRODOS and works as below
This board doesn't have RAM so, the ROM image is on the APPLE II RAM.
It is hybrid structure unlike other H/W emulation one.
Even hardware emulation, it can't say hardware emulation cause it has same logic design of the SC3000 and TMS9918 for Video.
Seeing is believing.
Watch it :)
The Z80 run 2Mhz but, it looks not slow running game.
It doesn't have any joystick nor keyboard so, I can't play but, I could see everything without delay.
Anyway, I will move this board for the MSX1 computer.
Someday, I could show running the MSX1 system on my APPLE //e.
