Oh yeah--I remember when 4116/2116 DRAMs were still new and in short
supply. The local Intel sales rep dropped off a number of 2108s
("half-good" 2116s) as a stopgap. There was a suffix on each one that
specified whether the bank (there were two "banks" in the 2116), should
be high or low.
I still have a few of those. Interestingly enough, some weren't bad
enough that prevented me from using them as 16Kb parts.
In any case, they were a BIG improvement over the 22-pin 0.400" 2107
commodity parts.
