I suspect these boards were OEMd from some Taiwan manufacturer of industrial PCs, actually.

The Besta series was like that -- apparently they bought the license and production line for Force SYS68K series boards. Later revisions had some original designs though.

I am not an Apple II person but seem to recall that Bulgarians cloned it pretty faithfuly (the Pravetz 8) as opposed to Russians (Agat 7) -- there's a fan page that describes how Apple II games were hacked to run on Agat: http://deka18.tsk.ru/er/agat/Gamez/Gamez.shtml
