Maybe I'm wrong, I always believed that the J3 connector was an RS-232
port. Here it is:

I also have the memory of a communication program under CP/M (maybe i'm
also wrong) about communication, a souvenir of baud rate (or it was in
the terminal mode ?). But perhaps for a synchronous connection only.

Fortunately the machine is complete! I still have the keyboard, the
cables, the documentation, the floppy disks. I also have a UTS20D with
the same keyboard.

You have a very nice retirement home, bravo, however no, sorry ;-) You
will understand that I am very attached to this good old fellow.

other story …
Except if I can finally also use that machine as a pure terminal (I
think it would be even more fun to connect it on my DCC-116 than on a
PC), if I can repair this computer, I probably will just use it as
before, namely under this good old CP/M, write some stuff in BASIC as at
the time of my 15 years ;-) However it should be great to find a way to
import others CP/M compatible programs.
> Do you have any way to image the floppies for it?
I never had the opportunity to explore a way to transfer files or
recreate a floppy disk from an image from my UTS. Finally I don't know
anything about the exact filesystem for this machine, I know that there
are ways to connect an 8-inch drive to a PC XT (for example), but on my
subsystem the floppies are double sided, 8 sectors 1024 bytes, I think
it's more than 1Mo per floppy DD. I don't remember if the subsystem read
also the single sided floppies, maybe. The question is, 8-inch drive on
XT ok but with which type of controller ?
Afterwards, was the formatting standardized between the CP/M machines of
that generation with this kind of media ? I do not know, but the subject
interests me.

I don't think I have any maintenance information but I think I have a
few 8" CP/M disks somewhere.

Thanks for all these information, I am not registered on the VCFED forum
but I will remedy this.
About saving information, firmware, dump ROMs, I would do that, although
I admit to be a little afraid to damage my ROMs, in the same time it
would be the best guarantee to cure the UTS in the future.
To finish I take the opportunity to show you some pictures of my machine
but that they date from today :
