Thank you for that program. I tried print chr$ the option rom address $ to
$8000 and there are some stuff at the very beginning, but nothing identifiable
and then it's just pages and pages of mostly ";" + 0 (59, and 0). Weird...
The first bytes starting from $ are 56, 191, 239, 255, 19
A search in the list archive for "opt2s.asm" will get you a post where a
program to dump the option rom contents out the serial port was posted by

the contents.
Perhaps something like
FOR I=62000 TO 65535: PRINT CHR( PEEK(I)); : NEXT
then look for something readable like "Option ROM (C) 1986 Club100" ... or
whatever. You might need to change the starting and
I have a model 102 with 32k ram expansion which I got in the 80's. I
just recently rediscovered it in closet and found some rom installed in
the option rom slot. It has an eme systems logo on it, but I have no
idea what it is. I've already tried calling 63012 and 63013 and the
