Marpet M1207 Jumpers
« on: August 09, 2011, 06:32:33 AM »
I recently bought an A1200 with a Marpet Developments 1207 RAM/FPU/RTC board fitted. I've just picked up a 8MB SIMM to replace the existing 4MB SIMM fitted to the board but I'm not sure what I need to set the jumpers to for the new 8MB SIMM. Can some one help me with the correct jumper settings?

I recently tested this with my M1207 and I got it working setting all jumpers on pins 1-2 (8mb).
 
I switched back to 4 MB though, because it made my PCMCIA slot unuseable ( yes I tried with KS 3.0).

Thanks for that, I set all the jumpers in a line closest to the 8MB inscription and it worked fine.
