This is actually of some concern to us.

Unless by "real PDP-10" you mean specifically a KA-10 or KI-10 processor
and associated peripherals, I'm going to have to object on behalf of the
XKL and Systems Concepts products, along with the Foonly family and the
MAXC system built at PARC.

I am firmly on the microcode side of the "real hardware" vs. microcode
argument when it comes to defining system architectures.  Otherwise, the
KL-10 processor is not a PDP-10.

I am also on the architecture trumps manufacturer side of *that*
argument.  The Amdahl, Hitachi, and Fujitsu articles are just as much
360/370 systems as the IBM offerings; they'd be just as desirable for
the work they can do (if not more so).  Nameplate coolness factor does
not equate to architecture, IMAO.

Anyway, as far as I have been able to determine, all the KA-10 systems
left in the world are located near Johnny Eriksson, as are all the KI-10
systems.

Oh.  I didn't mention that, did I?  The Toad-1 system dissipates about
1500W in operation and plugs into a wall socket.  The KL-10, with the
original power harness, requires 240V x 60A 3-phase, with a power-on
inrush of ~12.4KVA, and a steady-state operational requirement of ~6-9KVA.
