The Toad-2 is an extended Toad-1 clone. It puts the entire Toad-1
multi-board system with improvements into a single FPGA.

It's running a slightly later version of TOPS-20 than the Toad-1 which
employs the architectural enhancements of the Toad-2.

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.
