That is great!Another person (i think it was on here) used a Mega1284, which was probably easier relatively speaking. One thing-there is a VGAout library somewhere. You might be able to output to a vga screen and have a command line!
Simply awesome!!!But why didn't you use a SPI RAM extension?
Where is the source? ;-)Would like to give it a try..Very interesting to use a 64kb area on sd card to mimick ram memory.I assume the 4 floppy images are dd-ed on 4 partitions of the sd card?Please keep this code as a separate (version 1) project, before you introduce ps/2 kb und display.thx,Peter
Thx. Would be glad if you upload also your sd card image so that one can write it directly with dd on a card.Peter
I've got stm32duino (stm32F103zet6 board) with 64kB internal and 512kB of external sram (wired via FSMC). The 512kB of sram could be used for the heap. I can allocate the 64kB of CP/M's RAM with malloc() in that 512kB space easily.So I may try to run your code on it, when available..FYI: External sram on stm32duino
