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. --Chuck
