I have had a look at the TEK 4052 instruction set against that of the
Motorola 6800. Most of the 6800 instructions are present - the one
exception is DAA.

Tek also introduce 43 new instructions, but I don't know what any of
them do except NOP2 which presumably doesn't do anything at all.

More reading required on my part, but I guess a port of FLEX wouldn't be
too hard provided it could cope with the BIOS, which on a storage tube
machine is bound to be weird.

That said, the Tek 4052 has a far better line editor than many
non-storage environments I've met...

BTW, I've had one request to provide a write-up of my VCF talk for those
who can't get to the VCF itself. Is there any demand for this? Sam, do
you want this for imclusion in a "conference proceedings" sort of
document? It will be difficult, though, to include all the demo program
outputs (must get my plotter working again!), manual pages, etc.

Philip.
