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. bb On Sat, Jan 5, 2019 at 1:37 PM Dr Iain Maoileoin via cctalk <cctalk@classiccmp.org> wrote: > > Off topic, but looking for help and/or wisdom. > > 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.
