The cluster controller for the KL (CI-20) talks to an HSC-50 with special software to support 576 byte blocks
There were no cluster disks on the system, just RP05s
Memory is vague, but they may have moved them onto the VAX that replaced it.
I was involved in the de-installation from the Long Beach school district.
It is a complete 2065 system that was still working when deinstalled.
There should also be a couple of disk drives. I still have some of the disk packs
that have been kept in a controlled temperature environmen.

I have a Wangco floppy brochure scanned on bitsavers. The 5.25" drive is the Model 82.
Found a picture of one on line. It looks like a couple of companies used them.
I've been in contact with Dave about it, and some of the documention on bitsavers is from them.
Imaging the floppies is challenging, because most models of Burroughs floppies are very un-IBM standard.
did you look at http://bitsavers.org/pdf/qume/terminal/QVT-102/QVT-102_kbd
the firmware is in http://bitsavers.org/pdf/qume/terminal/QVT-102/firmware/K301_14F2_8748.BIN
and there are 8048 disassemblers out there
1K of code and the schematic shouldn't be rocket surgery to figure out
the terminal...
nothing -- pigtail -- twinax cable -- pigtail -- twinax cable -- pigtail -- balun -- RJ-45 cable -- balun -- converter
so you need to terminate the right-hand end with a terminator. the 'nothing' at the left end is actually a terminator
IBM never really documented the 5250 twinax protocol the way they did for 3270.
National wrote some informative app notes you can find under http://bitsavers.org/components/national/_appNotes/
for their DP8244 biphase communications processor, in particular AP-516 and AP-517
so for point-point...
