That sounds like a fun project. :)

Laurence Wilkinson has already done that for the 360/30. It will fit on the same board as
the 1130. On 14/04/2013 19:47, Mouse wrote:

Unlikely. For some purposes, I would too.
For other purposes, nothing but the real hardware will do.
Isn't that the fun of computing. There is a whole spectrum of what folks
enjoy, and wouldn't the world be a boring place if it wasn't so. I am building an
IBM1130 Emulation using an FPGA using Richard Stofers code., but I still run the IBM 1130
emulator?..

He has posted on here and he is working on getting a real Selectric connected as the
console. There are also implementions in FPGA of several other CPUs, including PDP/8 and
PDP/11 (but not sure how complete the PDP/11 ones are). Some like Laurences are "gate
acurate" emulations and others like Richards are "Behaviourial" so a kind
of cross between software and hardware emulation.
Very interesting!
That would be interesting to see how small it could be made now! :)
You can't really shrink the Selectric very much. It would be nice to do a
360/67 and run MTS though. My next project is going to be a Ferrantti Pegasus ..

but what I would really like for this are some of the GPO style switchs.... (They are GPO
style because the British Post Office rang the telephone system in the UK for many
years)....
