Yes, there are machines like that - in my case, the PDP8 was one of them.
On the other hand, I didn't even know what a PERQ was when I was offered
one - it was basically 'Would you like a PERQ - we have one going spare',
but I fell in love as soon as I saw it...

I thought the Terak had a Qbus backplane and a standard LSI11 CPU card. In
which case it's as close to a PDP11 as anything non-DEC ever can be...

Talking of obscure PDP11-related machines, has anyone else ever come
across the Tektronix 8530 etc systems. These machines were sold as micro
development systems and lived in 2 racks - one contained an LSI11 (or
PDP11/23) CPU card + RAM + disk controller + I/O + drives (either a couple
of 8" floppies or one floppy and a Micropolis 1200 hard disk), while the
other contained the development options -- in-circuit emulators, logic
analyser, EPROM programmer, etc. They ran either a much-hacked RT11 or a
much-hacked Unix.

You mean you don't have _anything_ with an Intel CPU (4004, 4040, 8008,
8080, 8085, 80x86, 80x88)?

The portrait screen means it's probably a 1, 1a or 2T1. While _all_ models
could use such a monitor, the 2T2 and 2T4 tended to come with 19"
landscape displays.

Uh-Oh. I think we all ran out of space _years_ ago....

Moving a large collection of machines is a right pain - in my case, even
considering fitting all the shipping clamps, parking the heads, locking
things into the racks, etc would take a couple of days.
