Usenix wasn't good at archiving.
I was told they were given a set of early conference proceedings and tossed
them.
Would be good for people to keep an eye out for them.
We don't have a complete set either

All,
I've recently scratched a curiosity itch on what it would take to build
a multi-port Twin-Ax to WiFi bridge. The electrical interface is easy
enough and ESP32s are cheap. So I built a bridge PCB-to-FPGA adapter
and connected my System/36 (5362), an InfoWindow II (address 0 and 1),
and my b

YES.
Although 8" "emulation" sometimes cheats and uses 80.
And some users with drives without a physical stop tried to squeeze a few
more tracks (and 41,42 on 360K)
The inability to read those "extra" tracks on

Give that man a cigar. Apparently the P112 doesn't know the
format of 8" disks even though it has an option to set a drive
as 8" in the config.

A lot could depend on how the software is interpreting the FDC return
codes.

Alan,
You may have already read it but page 9 and 10 of the "MPA-II–A
Multi-ProtocolTerminal EmulationAdapter Using the DP8344" document may
be helpful.
It enumerates the 5250 commands but unfortunately doesn't list the
command values.
Also pages 47 and 48 of the "DP8344B Biphase Communications

Somehow I think it was built that way by design (the board outline fit on a

From some slef-progress and a few replies.. an update.
I've managed to figure out the rough framing of the TwinAx messages from
primarily this document:
