A4091 install
Well the only other idea is that a few 3.1 processor cards escaped from
Commodore without all of the upgrades needed to make the 4091 work. I was one
of the lucky ones to get this card and it took a long time to get a
replacement. If you get Amazing Computing magazine, you can read my sad story
in the "Bug Bytes" column in the December 93 issue. Anyway, U209 on the A3640
processor board must be a revision -02 PAL (Part number 391472-02). If it is a
revision -01 PAL, then operation with the 4091 will be flakey (crashes). Once I
got all the upgrades I needed the 4091 worked like a charm, but it was a long
road to success.
