As a general rule, you can use faster SIMMs (or chips) than are required by
the machine, you cannot use slower (i.e. 150ns in place of 120ns). The low
profile vs. high profile has to do with whether or not there is sufficient
clearance to seat 'em in the socket.  High profile SIMMs generally contain
standard 1 Mb (or 256K as the case may be) DRAM chips soldered to the SIMM
board.  Low profile SIMMs generally contain the itty-bitty "surface mount"
chips.  This can be a *very* important point depending on the system you
want to stick 'em in (i.e. "high profile" SIMMs can mean big trouble if the
clearance is insufficient). I have not seen any situation where "low profile"
weren't preferable to "high profile" (your mileage may vary depending on the
buckazoids you wish to spend :-).  I hope I got all this right! (As per 
usual I try my best, but I wouldn't take what I say as 100% defect free
or invulnerable to misinterpretation ;-).
