From: Richard <legalize at xmission.com> Apparently not, at least for some of the Eastern Bloc clones; see http://hampage.hu/tpa/e_index.html. For the Hungarian machines, cards were definitely physically different, I'm betting things like power supplies are local creations and anything using LSI (F-11 clones, for example) were undoubtedly somewhat original due to differences in the manufacturing processes the Soviets had access to (and DEC never made anything that looked like a K1801VM1). Very faithful clones as far as the software was concerned, though.
