?: marks items I am unsure about.
PDS slot in IIvx is an accelerator slot.

SIMM's currently come in 256K, 1M, 2M, 4M, and 16M modules.
To add memory, an entire bank must be filled with the same size modules.

I seem to remember that the IIci was sold with a 128k external (i.e. in
the cache slot) cache plugged in.  Please, no flames.  If you know, please
post!  With source!  Until then, treat this item as unconfirmed.  This is
an edu machine, of course, if that makes a difference.

I also remember from previous threads, here and elsewhere, that the IIci
and others had the sampling hardware, yet it was not taken advantage of
through the OS.  It might be impossible to use it through S/W, it might
be completely wrong, or I might be right.  Don't know.  The data sheet I
have on the IIci does say "Apple's custom digital sound chip provides 8-bit
stereo sampling at 44.1 kilohertz, ...."
Excuse me, I just re-read that.  This is the sound generation hardware!
Terribly sorry for the previous confusion!

ROM in the IIci provides: 32-bit addressing, HFS, 32-bit QuickDraw

This is not your private newsgroup.  I am providing this information because
I have it and I believe it would be of good use to others reading this
newsgroup, including the many lurkers we never hear from.  It is possible
that others might provide further information because of information (correct
or incorrect) that I provide here (page out: P. Stadelmann mentioning the ROM
in the IIvx allows use of a RAM disk, something I myself was provided through
the OS, not hardware. Also, the larger ROM means that much more of the OS is
provided in ROM, so allowing more room to the RAM-based OS to load additional
functions, or execute faster. page in).  And I really do not appreciate your
claim at my distributing falsehoods, giving the impression that you view my
actions as malicious, or myself as uninformed.  If I were so stupid, how is
it I provided such a large list?

Hope this provides useful.  Please, no mail, it will bounce.
