With 4M, SunOS 4.0.1, and Sunview it will stagger along. In a dim, distant
past, that was my work desktop.

Even with 12M, X will be slow and swapping somewhat.

The NetBSD GENERIC kernel is now too big for 3/50. The kernel to install
and use is the INSTALL kernel.

All 9 of my 3/50 boxen either have 8 or 12 megs of memory. They are all
Clearpoint daughterboards with 1 meg simms.

Yes, there were 2 or 3 vendors.

A Sun 3/50 with 8 or 12 megs could probably be used as a mail/dns server,
but I wouldn't want to try to run a GUI at the same time. Running NetBSD 1.3.3
would probably be a good bet as it is reasonably small and is Y2K compliant.
