Your are correct it required +5 and + 12 for the logic board.
The Tu58 was packaged as a standalone with internal supply, same box but
uses the hosts
supply (variant), and it was also embedded in the VAX-11/750.
the Tu58 in the PDT11/110 was a parallel interface version but very similar.
I have all four flavors.
Yes and also power.
There are also two drive selected lights.

Hi.
I have one TU-58. Doing a resume:
* The components work at 115 volts, even when you can change the PS current
to 220-240 volts.
I am pretty sure the logic and drives run of low voltages (+5V,
+12V I
think). The only place you find mains is in the PSU (if you have an
internal PSU, not all TU58 units do).
* In
appeareance the Current flows by the main board of the device (the RED
led indicates so)
I thought the LED on the controller board (if that's the one
you are
refering to) indicates that a self-test has passed or something like
that. It's not simply wired ot the power line.

* The wire wrapping is the stablished in factory
(TU-58 manuals, Bitsavers)
* It has not stablished the 'boot' wire wrap for LSI-11
* I have one DEC console serial cable
* I have too a couple of Dectape II cartridges
With all these stuff, I should like to connect the TU-58 to the Serial Port
of my Laptop and manage the TU-58. The objective is:
* To put a virtual image in the Dectape II from the Laptop
* To dump the content of one Dectape II in the Laptop
Are you interested in just
copying image files to/from physcial TU58
tapes, or do you wnat to be able to access individual files on the tape
(which I assume requires knowledge of the OS used).
if the former, the TU58 protocol is documented in the manuals. It
shouldn't be too hard to write somethign that reads an image file one
block at a time and outputs the appropraite commands to write that block
the TU58 tape. Or vice versa.
The unique option similar to this that I want is
one MS-DOS driver in
SpareTime Gizmos, but to use the TU58 as one MS-DOS storage unit. But, what
I have in mind is similar but different at the same time. I want to manage
the TU-58 contents in DEC native format.
I am not sure what you mean here. The
TU58 itself has no concept of
files, directories, etc. You access it at the block level.
