Glad to hear it's working now -- I hope it continues to!
Memory for the 100 is a bit of a problem. Electrically, the modules are compatible with those for the 140, 145, 170...etc. Unfortunately, there's no room in the 100 for those modules beyond 2MB. Special (read: extra expensive) '100-specific modules are needed. They are hard to find, and costly when found.
In desperation, I've made my own. You can desolder the chips from a 140's expansion card, e.g., and stack them atop the chips in a 2MB module. Solder all the pins together except for the enable lines, then separately wire the latter to the appropriate card pins.
(And btw, the 100 maxes out at 8MB, IIRC, not 10MB.)
