Making an apple iii replica
Hi guys i'm making an apple iii replica using nothing but the original apple iii schematics. Here is the I/O logic board section. I think its nearly fully complete. It took a few days to make just the I/O logic schematic on easyeda lol

Nice work.
After that, someone should create a replica plastic case too 😀
I guess this would be my only chance to finally have an Apple /// at a reasonable price 😀

You could look at the code in MAME -- we know that's functional, and it's documented. It should at least tell you how all the components in your schematic are supposed to behave.
