Built another 27C512 EPROM to 6309 PROM footprint adapter. This one will go in the IO board to control the floppy drive. I’m now using these small protoboards with are a good fit. I plan on adding a GAL socket to the right to make it a dual purpose adapter so both can be tested.
I have one set of #AppleLisaClone boards for sale in the USA: the I/O board, motherboard, LisATX board, and card risers/extenders for diagnostics. You provide your own CPU and RAM cards. DM me if interested!
Let’s build up a two port parallel card for the #AppleLisaClone! I wasn’t expecting to build one of these, at least for a while but I accidentally ordered the parts for it (which was confusing at first, trying to find locations for mystery parts with no boards for it). 😅
Since I’m impatient waiting for my boards to be delivered, I created a 27C512 EPROM to 6309 footprint adapter (more than just DuPont wires this time) for the #AppleLisaClone CPU card. It too reads fine in the EPROM burner, masquerading as a 6309 properly.
Plugged in the 6309 “VSROM” emulator into the (original) CPU board of the #AppleLisaClone along with the two missing ROMs and the 68000. That completes this board.
Hopefully some more parts for the IO board will be arriving soon.
I'm falling down a rabbit hole learning how to use WinCUPL to program a GAL22V10 to replace the PROMs in the #AppleLisaClone. I think I have a PLD file created with the PROM contents but keep running out of product terms for one output. I guess this would require hand optimization to fit within the limits of the GAL.
#ArcaneByte#mac2lisa keyboard adapter. This allows me to use a Mac 128/512 or Plus keyboard with the #AppleLisaClone There’s also a version that has ADB but I decided to go with a Plus keyboard because it looks the part.
