[SATLUG] An AT (antique computer) question

[Charles Hogan]

I also recall some MB's that had both SIMM and DIMM sockets when DIMMs 
were first staring to hit the shelves.  If I recall correctly, you could 
use either the SIMMs or the DIMMs, but not both.  I may still have one 
of those machines collecting dust somewhere.  Ahh - the good old days, 
having to buy matching SIMMs, setting jumpers on everything you put into 
the machine...
