Sperry UTS 40 on Ebay - Statesboro, Georgia

In fact, I used this machine from 1988 to 1999 (the date of the
breakdown). This machine was given to me by my father who worked as a
programmer on a Sperry UNIVAC 90/30, among others. This UTS 40 has a
sentimental value because besides the paternal donation, it was my first
"serious" machine that evoked me the loved big mainframe and computer
terminals (In 1988 I was 15 years old and I had only an Amiga 500 and a
Commodore 64). I wanted to give it a usefulness and under CP/M I
programmed a soft in BASIC to manage a database which was a big
help-memory-reminder in which I noted all that passed by my mind, a lot
of funny stuff, dreams, projects, ... ;-)
My UTS was on every day and I used her constantly, this machine seemed
indestructible however after 20 years of good and loyal services it
began to show signs of fatigue. I had sometimes an error message during
the POC TEST at initialization (RAM or ROM error, I can not remember).
At this time I incriminated my brave cat who was watching me tapping on
the keyboard and sleeped regulary on the top of the screen that served
her as heater, thus blocking the normal ventilation of the machine.
One day I turned on my UTS and instead of the POC TEST, just a long
"BEEEP" and nothing on the screen. As I remembered the RAM / ROM issues
displayed via the POC TEST, I suspected the ROMs on the "program
cartridge". In fact I knew a lot less electronics compared to today.
Fortunately I had printed all of my writings with the manesmann-tally
dot matrix printer that was connected to the machine shortly before the
I think today that it is possible that the breakdown was simply due to a
deficient diet because of aging capacitors.
If today I put it on, there is no longer BEEEP, nothing. I always told
myself that I would refurbish it one day and that I would start with the
PSU. But there is the underlying fear of a more serious problem with
ROMs or RAM, or more vicious, with the numerous tantalum capacitors
associated with the RAM (already observed with my IBM XT).
The subsystem has long been functioning after the death of the terminal,
now there is a breakdown of power supply (bridge rectifier apparently),
and the belts are melted, but nothing serious a priori.
In short, I want to restore this machine :-)
It was a synchronous terminal but there was an RS-232, if I could repair
my brave machine and make it communicate with my other machines it would
be great :-)
In any case, that's why I've always been interested in finding spare
parts for this old buddy.
I had already tried to talk about that a long time ago on a forum, I
just found the link:
And finally here, four images - Classified file ! - a video from 1989. I
was 16 and so happy to have fun with my dear UTS 40 ^_^
Will I ever resurrect him one day?
