Thanks everyone for your suggestions.? Here's an update:
1) The "terminal interposer cable" implements exactly what I had already
tried? with my rs-232 breakout box, namely (taken from the net):
So, if I were to hunt for installation media for
AIX, which version
would you recommend for a 320H with 32MB of memory, i.e., the latest
that would run and not get too bogged down by that amount of memory??
I can switch to a larger SCSI disk if it need be, but hopefully not
larger than 2GB.

I am no longer sure when support for microchannel was dropped from
AIX, I have always been on the hardware side with limited involvement
with software.?? Doing a quick look it would seem that it is likely
that some level of version 5 was the last one. Version 6.1 was 64 bit
only and required a POWER4 or later processor.
Paul. DB25????? to???? DB25????????? or????? DB9
2 TD????? to????? 3 RD???????? -?????? 3
3 RD????? to????? 2 TD???????? -?????? 2
4 RTS???? to????? 5 CTS??????? -?????? 8
5 CTS???? to????? 4 RTS??????? -?????? 7
7 GND???? to????? 7 GND??????? -?????? 5
6 & 8 DSR & DCD to 20 DTR????? -?????? 4 (very important)
20 DTR??? to????? 6 & 8 DSR & DCD -??? 6 & 1
Still, no luck making the
console work; the 320H does not assert DTR or
RTS even though it is seeing DSR, CTS, and DCD asserted.
2) I cleaned the floppy drive (it wasn't that dirty), re-wrote the four
aix diagnostics floppies and tried them once more in service mode.? The
same thing happened: it reads the complete first disk (apparently
without error), but then it goes again to read the hard drive and stalls
in the same spot.? Does anybody have images of diagnostics floppies that
would be known to work in a 320H?
3) I now have AIX 4.3.3 install CDs.? Does the 320H expect a CDROM drive
to be at a specific SCSI ID?
