Personally, I'd be more interested in hearing more
about the "TOAD-2"
controllers used in current XKL equipment, starting with:
I'm not sure I'd agree with the designation "controller".
Is the TOAD-2 a PDP-10 clone, as the TOAD-1 is?
The Toad-2 is an extended Toad-1 clone. It puts the entire Toad-1
multi-board system with improvements into a single FPGA.
Is it running TOPS-20 (or some subset)?
It's running a slightly later version of TOPS-20 than the Toad-1 which
employs the architectural enhancements of the Toad-2.
If not, is it a self-hosting system (is development
for the platform
done on a TOAD-2) or is it an embedded processor, with binaries being
cross compiled on some other platform?
Ralph has told us that (at least at one time) Toad-2 systems were being
used by (some of) the engineers as development platforms, so I would
call the Toad-2 self-hosting.
From what Roy Hirst has said, that may no longer be
true, but I have no
information on that point.
