gives a Little more history on Soviet copies of computers.
The timing of the production of the Capatob 2 seems to make it a
PDP8/L clone, not an M. What is called the 8 is really based on the 5,
used 6-bit bytes, 12 bit words, and was Octal based - memory was the
most expensive part of the system at least through the early 70s, and
thus 12 bit words for double precision, 24bits, was a reasonable
approach for a scientific computer.

If you visit https://www.scotnet.co.uk/iain/saratov
<https://www.scotnet.co.uk/iain/saratov>/ <https://www.scotnet.co.uk/iain/>
you will see some photos and wire-lists of work that I have started on the front panel of
a Capatob 2.
I plan to get the switches and lights running on a blinkenbone board with a PDP8
emulation behind it. (I already have an PDP11/70 front-panel running on the same
infrastructure)
I have been struggling for over a year to get much info about this saratov computer
(circuit diagrams etc). So I have started the reverse engineering on the panel.
Does anybody know anything about this computer? online or offline it would be much
appreciated.
