Aca500 with AT-Once PC Card

gurth · 14 February 2019, 08:34

Has anyone managed to get these 2 expansions to work with an A500’s before? I’m looking to buy an AT-Once.

I had an ATOnce+ back in the day but never a ACA500.

I don't think this will work. The ATOnce plugs in the internal 68000 'DIP style' CPU socket. The 68000 is moved onto the ATOnce board.

If I understand correctly the ACA500 plugs into the side connector and uses a PLCC CPU socket. I am sure it will disable the internal 68k CPU.

I could be wrong as there are different ATOnce models.

Ah yes I understand that makes sense. Thank you.

I also had a Votex ATonce and it worked well on the A500. I was able to run MS-DOS and most 286 software I tried at the time.
