The ibm 3174 was just a controller to then link the terminals to an AS400 mini / mainframe

The 3174 support async hosts among other conversions so it would be interesting.

I forget if this was one of the products that used the 801/AMERICA CPU, I don't think it's a COTS microprocessor.

I bought a 3174-1L from my university because it was $20 and I didn't know that 1) it was a boat anchor without the rest of the system and 2) it wouldn't actually fit in the back seat of a Hyundai Sonata and 3) it was wired for 208v so doubly useless in mu 110v country.

I'm pretty sure there was some sort of local processing power, since it had a floppy drive to load "firmware" discs. I await the Doom port.
