[6] Re: Mac IIci 30 pin SIMMs: 8 Meg or 16 Meg

[Ryan Schmidt]

It would depend on the specific Performa you want to pull RAM from. Of 
course the Performa in question would have to use 30-pin SIMMs (not all 
do), but then the RAM would also have to be fast enough for the IIci. 
For example, although the Performa 200 (a.k.a. Classic II) and Performa 
400 (a.k.a. LC II) were introduced years after the IIci, they used 
slower RAM. (The IIci requires 80ns RAM, but the P200 and P400 accept 
100ns RAM. ns stands for nanoseconds and measures the RAM's response 
time. Smaller numbers mean a faster response time.) So RAM from one of 
these Performas will not necessarily work in a IIci (unless 
faster-than-necessary RAM was originally installed in the Performa). 
The Performa 600, on the other hand, required 80ns RAM, so its RAM 
would work in a IIci.

The best tool I know of to find out this sort of thing is GURU, Newer 
Technology's GUide to Ram Upgrades:

http://hyperarchive.lcs.mit.edu/cgi-bin/NewSearch?key=guru+2.6
It has info on all "old" Mac products' RAM specifications and possible 
RAM configurations (and other hardware info) in an easy-to-navigate 
app. I would go so far as to call it definitive.

Another place you could go for some of the more basic specs (but not 
such essential info as RAM speed...) is the official AppleSpec sheets 
on the Performas:

You probably know this, but if you didn't it could
hurt you so just
to make sure: all four slots in the first bank must
have the same
kind of simms, and all four slots in the second bank
must have the
same kind of simms.

Thanks for the tip.  It appears on page 117 of the
"Macintosh IIci Owner's Guide" of wich I have a copy.
Does anyone know if Performer Mac SIMMs can be used on
a Mac IIci?
