   Anywhere from 4M to 24M in 4M increments of 1M 30-pin parity SIMMs,
100ns or faster. Nine-chip SIMMs seem to work more consistently than
three-chippers.

   NetBSD 1.4 is running on my 3/60's. SunOS 4.1.1 was pretty good, too.

   The 3/60 is a lot easier, because the onboard si works as expected,
unlike the VME ones.

   There's only one jumper block, and it's labelled pretty well. There's
six positions used to indicate the memory size, one for AUI/coax, and one
sets the onboard bwtwo (if present) to normal or high resolution.


   If you're going to run it diskless, you want to crank the memory way up.
I have a pair of 4M 3/50's with disks and they do OK for light use. On the
other hand, I have an 8M diskless 3/50 (third-party expansion board) and it
has real troubles. Doing a "ps -aux" saturates the network for several
minutes.
