CMjones;

Coincidence? I believe it is Very unlikely.

Most likely, the Soviet designers decided to maintain Tek compatibility, such that they could install genuine Tek modules, if the need arose for whatever the reason.

Hey @imo, any chance you still have the schematics for your S1-99? (C1-99) I just got one for a bargain price and I have my doubts about the big electrolytics in the power supply being still usable (and not prone to bursting).

Thanks in advance!

By the way, my unit has an English front panel with Bull Electronics BE-2 printed on it. It does still say "C1-99" on the side and that's how I found this post.

Cheers everyone!
Dax.

Bull Electronics! There's a name to conjure with. I wonder if it's the same company (J & N Bull) who used to advertise inside the front (or back) cover of the hobby electronics magazines advertising all sorts of surplus bargains, including their famous £1 "baker's dozen" packs. I still have some components bought from them, including one £1 pack which turned out to be a board from a Ferranti Pegasus computer, complete with valves.

S. Petrukhin:
To understand why the USSR copied technology, you need to know that in the USSR there was no intellectual property. Everything that was invented was done for the benefit of humanity, not for personal enrichment. There was no competition, just a socialist contest. Soviet engineers worked for a salary, sometimes received bonuses and awards, but did not become rich. All the engineers who conquered space and created the hydrogen bomb lived a little better than the road builders.
