hello,no they were not only games machine,it was possible to use floppy
disks with a version of rt11,and then to do assembly language etc...
Also the bk0010 and 0011 have focal,and basic in rom ,they have a rather
hight resolution graphic,and a parallel port(16 bits in/out)that can be used
to connetc many things,there is also a qbus compatible connector (by qbus
compatible I mean that from what I have understood ,the signals are ttl
compatible and their timing is qbus compatible,of course connector is not
the same,soviet computing industry had close links with european standarts
:they use 220v,secam for video ,euro connectors etc... )
For the fun I did quite nice astronomy programs
on them ,the results were as accurate (or better) than a pc .I also did
programs in assembly using the tape recorder ,somthing like we did with
tapes :edit/save/assemble/save/link/save/boot/run....fun also ,I like doing
assembly pdp11 on such a small machine,my wife also:less electricity,less
noise...look some results on my page.
best regards

Subject: Re: Russian PDP-11 clones, was Re: VHDL PDP11
I have a friend with another interest in Russia that
looked into them.
There is more than the two sheet flyer, but this VHDL project looks way
more doable, now.
The links are below from my friend Pavel.
I think most of the computers that were turned up were of the game type,
or were such that they required fluent russian to make much use of them.
This VHDL implementation would be closer to what I'd want to have to mess
with. That was one reason for asking what to do next.

Hello, Jim.
1). About chips.
I am not sure that this information is searched by you. But it could
be useful probably.

Is it interesting for you?
