Hello!

I have been working on interfacing the Hercules emulator with various real
terminals for some time. First project was an Alfaskop terminal cluster
which I connected using a small STM32 controller handling BSC.

Next is an Informer 213, portable 3178/3174 compatible terminal. It it
using SDLC.

A friend has a 3178 and 3279 which would interesting to work with. A
3174-51R/-61R/-81R/-91R would be very suitable for this.

It would be very nice to test my BSC and SDLC code with the real IBM stuff.

I have put my project here:
 https://github.com/MattisLind/alfaskop_emu/tree/master/Utils
<https://github.com/MattisLind/alfaskop_emu/tree/master/Utils>

Still very much Work In Progress.

If anyone has a type 1 3174 that does BSC and SDLC so I could test my stuff
I would be very interested. No need for fancy features like TCP/IP and/or
token ring.

I of course pay shipping. But can throw in various DEC QBUS stuff as a
trade.
