---Reply to mail from Walt Ezyk about [PCBUILD] 30 Pin SIMM Question

Hello Walt,

Funniest thing, I sit here looking at four 4Mx9, supposedly 30pin
SIMMs(I didn't look too close at the time), that I purchased used from
a dealer of used equipment here in Seattle.  These are not 30pin SIMMS,
but more in line with what you describe. They're about the same size as
30's but have the split, and 32pins to each segment. Which makes them
64pin SIMMs. Are you sure that the sockets you have in that board
aren't 32pins to a side? If they are 36pins to a side then they are
72pin.

Anyway, check it out and get back to me in the next few days. I'll
keep them until I do.

Hope this helps,
Paul
