I have a 3172 controller; physically rough and needs
restoration but *should* work if
I can fake the remote connection and modem - bisync etc. B

you need a modem eliminator mostly to provide the
clocks for the sync data line,
other than that is is similar to a null modem.
Not sure if this would work here, but the Cisco IOS "IBM Feature Set"
has support for all sorts of weird bisync use cases. I've used it to
fake termination of an ALC (Airline Line Control) bisync connection
where a modem connection was expected. You can then convert, tunnel
or bridge to any number of other strange things.
There even exists an IBM channel attach card for the Cisco 7k routers
that turns it into the equivalent of a 3172 and/or 3745.

Oh that IS interesting. I have a 3172; never done anything useful with it.
Maybe time to have a play. I do remember there was a version of the 3172
that had a P/390 card in it, to allow it to run some kinds of comms stuff
that normally ran on a mainframe CPU.
Cisco sounds useful too; I'll investigate that. So with the right cabling
you could potentially hook a 3277 directly to a correctly configured Cisco
router, then (say) telnet to a Linux box... Just as you can with a 3278
connected to a correctly configured 3174? 'Correctly configured' in both
cases involving the incantation of complex and obscure runes...

Grrrr I should have said "hook a *3271* directly to a Cisco router"
