Here's my rarest:
Tektronix 4132, running UTEK (A Tek-haved 4.2bsd variant). A National
16032-based machine, with 4MB of RAM, dual RS-232, CDC 320MB SCSI 5 1/4"
HD, GPIB, built-in 10Mb Ethernet (AUI), QIC-24 tape drive. Have quite a
number of expansion boards, including additional RAM, RS232, SCSI, and
parallel printer interfaces. The network stack in these machines is
pretty broken...it doesn't know about subnetting other than basic class
A/B/C, and it forces broadcast to the zero address rather than the
now-standard ones address.
Probably not too many of these machines around anymore that are running.
I also have a Tek 6130 that I believe will still run. Same architecture
as the 4132, but earlier.
It has ST-506 disk interface rather than SCSI. Don't have a decent
ST-506 drive for it.
Usually ran with Maxtor 1140's, which are pretty tough to find nowadays.
Built-in 5 1/4" DSDD floppy drive (versus SCSI QIC-24 drive on the
4132).
One of these days, once I get my house built and I have a real shop to
work in (probably not until early 2005), I'll have to drag these beasts
out and bring 'em online.
