[comp.sys.apple] non-volatile RAM's

TMPLee@DOCKMASTER.ARPA (12/15/87)

Several manufacturers advertise RAM's (for the GS, specifically) that
have power continuously supplied to them (usually also with a
rechargeable battery to tide one over power outrages) so they can be
treated as something like a hard disk (but very fast).  (I'm including
here also the adaptors like the Checkmate MemorySaver.)  Other than
price, which varies slightly from one to the other, can anyone give a
reason for buying one brand over another?  I wonder, in particular, some
say that one uses them like a ROM disk -- does that mean its awkward to
update them?  (and how does one address a ROM disk anyway?  is there
such a thing as /ROM5?)  Do some look like "ROM" whereas others look
merely like a /RAM5 that never forgets?  Given what I use my system for
I don't really want a hard disk (keeping documents on 3.5's is just
fine) but it sure would be nice to be able to load the half dozen or so
applications I use quickly; a couple of megs ought to do; however most
of them do have initialization files that tend to get changed from time
to time so what they boot from can't be read-only.

p.s., I did read a report from one of the other WordPerfect beta testers
that he had a Checkmate Memory Saver and it worked very well -- which is
sort of what prompted my question.
