[comp.sys.mac.misc] Mac SIMMs vs. PC SIMMs

Greetings, netters!

From "Macintosh Repair and Upgrade Secrets," Larry Pina, 1990, page 205:

[words in *asterisks* were italicized in the original]

"PC SIMMs are the same physical length as Macintosh SIMMs but they contain
 nine RAM chips instead of eight.  These work fine in PC's *and* Macs.  Eight-
 chip Mac SIMMs *only* work in Macs.  If you have access to nine-chip SIMMs,
 or if you might need to use them in a PC someday, don't hesitate to try them.
 Assuming they're first quality nine-chip SIMMs, they'll give equally good
 service, in either machine."

Is this true?  I'm not about to mess with my SE/30's internals to test it,
but it would sure be nice to hear that I can upgrade using some of these 1 meg
PC SIMMs floating around here ...

This is one instance in which PC hardware costs the same or more than
Mac stuff.  There's no real point in hunting for parity ram for a Mac
unless you want to upgrade a IIfx.  The market for used RAM chips will
probably continue to be good among Mac users;  I wouldn't worry about
wasting $$ by investing in 8-chip SIMMS.  Best investment you can make
for a Mac ....              -- Bill (johnston@minnie.me.udel.edu)
