I can't use a CDROM as it's read-only - but maybe a CFFA-like
device will pop up?

Sounds bad!

It stems from the fact that a RamWorks III with 1 MB offers
only a few more blocks than that for its ramdisk as it also
supplies the 64KB aux ram.
I guess the situation applies to all 1MB RamWorks cards and
I want to support them.

OK - 1 MB will be the ceiling anyway.

Yes, but do you guys max-out your IIc's like your IIe's and
IIgs'ses or is the majority of the c-models still at 128K?

A very interesting setup - if it survives the next years you
may be part of my audience ;-)
