The terminals are models UTS20, UTS30, UTS40, UTS50 and SVT1120,
|

however only the UTS20 is dumped (program roms only).

The terminal has 2 screens selectable by the operator with the Fn + 1-2
|

buttons. Thus the user can have two sessions open at once, to different

mainframes or applications.

This driver is all guesswork; Unisys never released technical info
|
||||
to customers. All parts on the PCBs have internal Unisys part numbers
|
||||
instead of the manufacturer's numbers.
|
||||
|
||||
Notes on failures in power-on test:
|
||||
* Test 2 checks RAM parity. Patched out
|
||||
* Test 5 tests ROM checksum. It seems one or more roms is a bad dump.
|
||||
* Test 7 tests SIO ch B. The SIO should cause 9 interrupts. The CTC is
|
||||
programmed as a time-out. But SIO only does first interrupt then hangs.
|
||||
CTC then fires causing the failure message. It's unknown which CTC
|
||||
channel drives Ch B, none seem to work. CTC trigger frequencies are
|
||||
all guesswork too, but the present setup allows Tests 3 and 6 to pass.
