Cool ... an Apple II, a SD/MMC card for storage, a Z80 CPU, 80 columns card, all together implemented in an FPGA prototype
Amazing what is possible !
An Apple II and some peripheral stuff, fully equipped, and almost 100% compatible, but not running on old hardware - it can be done with a prototype board (Altera/Terrasic DE1 board).
Alex Freed did that ... his first steps began earlier with his FPGApple,
I managed it to downgrade a Turbo PASCAL (5.5) Source of a Z80 Assembler to a Turbo PASCAL 3.0 version...
... and it can be compiled on DOS error free. Now I tried it on CP/M 3.0 and guess what happens ?
It was too big, over 50KB size was too much for the Compiler. So I was reminded on these days and the size limitations suddenly again :-(
I am sure it can be stripped from all comm
