[TUHS] UNIX on S/370

I don’t think PS/2 hardware is going to be an issue.    The i386 i/o architecture is pretty much the same, in/out instructions, despite the cute allusion in the name to the  IBM Channel architecture, the microchannel is just another PC memory bus like the ISA it “replaced.”   Not to say it had some good features to it (the idea of a card ID and better spped).    The machines also had a few ISA slots.

As would I. I'd also be interested in that i386 AIX Clem mentioned


A big issue/hurdle I suspect is that AIX/386 was done for a PS/2 HW; (microchannel) which besides IBM and NCR, there is not a lot of in the wild.   So simulation might be a PITA.​  Also the graphics was done for some IBM specific displays (I've forgotten the names), that nobody else made (which were really expensive at the time IIRC -- which again may have been an issue on why this was not popular).   


We had a lot of Gateway 386 (ISA/EISA based) PC's at Locus which were the system of choice we used for TNC prototyping and all we had in Boston and San Diego.   The LA guys must have had AIX running on them; but I'm not sure if that code was ever released.  I'd have to ask some one like Hopfield who would have done that kind of hacking.
