Both the CLCC on substrate and the factory-stacked DIPs were actually
quite reliable. Until ZIPs, SIPPs, and DIMMs were invented, that was
the highest packaging density in common usage for RAM.
I thought one DIP had an inverted CS, Though I might be wrong. I did the
stacked thing on my atari 400,
Stacked 8K chips to get 16K. But that was in 82 and the atari H/W
