Greetings again:

It looks like V1.5 and it is a three chip set. Again, I don't recall why off
hand, but I think there are four total, but for some reason, one of the patch /
code chips did not change if I recall, but the two CPU chips need to be upgraded
for sure.

The Binaries are about 32k in size, but once again, if I recall they are on 64k
chips. I will have to wait until I get home and pull them out of the box. They
are chips 6, 10 and 11 on the system board anyway.

BTW: A system reset will wipe out any user patches, so you should save them via
MIDI or cartridge before hand.

Regards;

Peter
