Brad,

You should't forget about the cold war and the Curtain. In those old days we
dealt with a technical equipment made in Eastern Europe and Russia only.
Thus and so I'm familiar with Robotrons and ZXs as well as with a few native
ones, but other names look to be unknown to me. Maybe I saw some of them in
the press but I'm not sure. So I think you could forgive my ignorance of
these brands :-)

Cheers,
Dmitry
