Cheetah Cub board

hmmm, I thought there were four rows of 18 chips. That sounds like 8 banks of 256K which seems
like 2meg to me... unless I got something wrong

as for board worth, the 256K chips are worth a bit. I found a site that had them for sale at $0.75 each.

If you need a PC to run it in, buy one on eBay... LOL (couldn't help that one)

best regards, Steve

   Ehh? 256K? So either the board provides 16MB of RAM, and the 2Mbyte
  silkscreen is just the shipped configuration, or somebody was wasting
87% of their money?

   BTW, the 10ns was a brain fart. I dunno much about DRAM, but I can
read the -6, -7, and -etc extensions... :)

   So, more relevant to me, is the board itself worth anything outside
the DRAMs? I have a friend doing a 68000 SBC project who could use
some, and I think some of the rest would look fabulous on my Amiga
2000's A2091 board.

   One note - It looks like the DIP switches can be set per bank, but
without docs, I'm guessing that taking any of the RAM off will render it
inoperable.

   But I don't have any old PCs. :)

   BTW, your line wraps seem to be set to 256 or something.
