What?  Every Mac I have seen, which is quite alot, has SIMMS, not DIPS.

Yes, yes, dozens of times, yes!  It may fail after passing the diagnostics
the first hundred times!  I have seen it happen more than once.  Get them
suckers good and hot and put them in the test loop overnight.

I have seen many motherboards with TI, Motorola, and Hitachi 256k chips.
I have successfully used many (thousands each) TI, Motorola, and Samsung
256k 120ns chips in UNIX-PCs with 0 failures.  150ns chips seems to be
harder to find than the 120ns variety.

The only ones I have seen fail were Fujitsu. ( 3 out of many thousands )
