How To...

I have come accross this problem many times and the cause is one of two things or both.

1. Faulty 8501 chips very likely
2. Faulty RAM chips also very likely, but less likely than 1.

I would start off by replacing the ram chips first on both machines.

To do this visit

and click on the "Instructions for C16-memory-expansion to 64kb" link.

after doing this if both still don't work then you have faulty 8501 CPUs.

I also will be uploading detailed repair / Testing instructions and schematics for the C16 Published by SAMs to the C16 Plus4 Supersite next week.
