The SR should've had a shim/cardboard attached to it's underside. I'll try and

Scott,
After reading your shopping list of wants, I think a REX is a great
solution, and developing an option ROM is really your best path.
But you don't need to do a rip and replace on the main rom to get there.
I personally think it is a very bad idea to replace the stock MAIN ROM,
with REX.
NM this question. I think I have gotten a handle on it now. The FlexROM 100
replaces the main system ROM (only really useful for my M100 with the
non-standard socket)
The Rex is an option ROM replacement that allows me to store several option
ROMs at once and also allows me to store my own
Will do. Just so I understand, the Rex replaces the main rom? The M100 will
boot directly from the Rex? And with the Rex, I can customize my own
applications, autolaunch, etc? This goes into the DVI socket on the bottom?
I had looked at it before, but the descriptions seem to be written for
Scott, I recommend before you jump into a REX solution that you read my

Actually with rex classic you don't even need any rom in the main rom
socket so you don't need any of those boards, just a single wire from the
/CS pin in the main rom socket out to the REX. You just can't run the
machine *without* the rex after that without opening back up to put a rom
back. The

I would suspect the screws are metric as the M100 was designed by Kyocera in
Japan. A 3mm screw is about the same size as a #4.
