In rummage through the dark recesses of my garage (too
densly packed to let

memory chips. Were there any other computers that used these things?
The Apple /// 128K memory board used 32 pieces of standard 16K DRAM, and
16 pieces of 32K (stacked 16K) DRAMs.
Several TI calculators including the TI-58 and TI-59 use stacked DIPs for
RAM.
The HP-41CX calculator uses stacked DIPs for ROM and RAM.
