Hello everybody,
This is the final note on my request to identify a piece of
hardware that I got.
First at all, thanks a lot to Wolfgang Moser, because with his help
I found out that I got the RAMBoard for the 1541 II drive. I tested
with a drive that I bought at Ebay.
As Wolfgang guessed, the board fits perfectly over the DOS ROM chip
and maps its RAM at the $8000 address. I connected the A wire to the
pin 24 and the C wire to pin 8 of the 6502 CPU. The B wire is
connected at pin 21 of the 2016 RAM.
I ran the RAMBoard test program, found at FUNET. I tested the
RAMBoard's Maverick utilities and everything went without problems, as
far as I can tell. Does anybody has another programs to test the
expanded RAM?
Well, that was another mistery solved with the help of this great
community.
