for those who don't know what I meant by "the IBM 37T", it is an unreleased prototype IBM deskside mainframe-workstation that ran a custom operating system called EM/YMS; since that OS is going to be a hard pill to swallow for a lot of people (it's basically a Lisp machine, except the editor is Ed and the language is EXEC II and REXX), the goal is to instead make it run VM/SP Release 6 (which has TCP/IP, RSCS for store-and-forward file/message sharing, VTAM for SNA mainframe networking fun, compilers (three C compilers, COBOL, FORTRAN, four assemblers, Pascal, REXX, BASIC, etc), the ability to run TOOLS to host/access mainframe BBSes, and more.

the workalike of the 3274 terminal cluster controller will run a 3270 datastream over a serial port, which can be driven with a 3270 emulator running on a PC

the ethernet interface on the 37T is radically different from the ethernet interface the VM/CMS TCP/IP stack expects, but fortunately emulating the one it expects (the IBM 3172) is easy because I have like two of those and the Hercules mainframe emulator emulates it with ease

I will work my ass off on making this real over the summer
@wec good luck, I look forward to any updates about your progress that you share! I do also hope that continued research into the 37T will reveal some way (e.g. by a software emulator) to run EM/YMS someday: as a #PERQ botherer I am so curious about what @d_j_fitzgerald suggested was (something like) IBM's answer to the PERQ.
yeah I need to sit down and start modifying Hercules to add support for the Multibus memory segment

@wec @stepleton actually, ti my understanding it ran VM/370 with EM/YMS as the guest
