It depends what mean by "film scanner". The Eastern Block was no more by 1991. If you refer to scanner for film for private use, back then there was not such in the West either.
Do not overlook that in the Eastern Block there were no PC (to western standard) available for consumers, but only for administrative or commercial users.
