THX, comrade! I'm way too tired to go through GttMFH2E tonight.

I'll probably scan and print the entire memory sections for the IIfx and the IIci and then print the same section from the IIsi DevNote so I can three-hole punch the lot for inclusion in my "Hacks Binder" when I get a chance.

I'll have to check out the release dates of all three machines.

I'm sure the IIfx ROM is based upon the IIci ROM because Mac II Video shows up in the SlotInfo Reports and the IIfx AIN'T GOT NO VIDEO! The IIsi has been described by at least one member as: "a IIci with a microphone input."

We'll see, but I'm fairly convinced that the IIfx ROM SIMM ought to boot the IIsi . . .

. . . with a MUCH more flexible memory mapping scheme! :approve:

. . . or not! :-/
