Medical VTRs are nasty. These were used in places where germs and sickness were in the air. And that lovely little VCR fan would just suck those into the unit, spewing them all over the mechanics of the deck. Medical VCRs should be the least desirable of any VCR for that reason alone.
Beyond that, these are tuned only for SP. That's probably why tapes are "too fast" (LP or EP/SLP), as it does not understand extended tape modes. And tracking will be off for the same reason. Even many SP tapes may not track well.
These were intended for recording only, never playback, not even editing.
S-VHS only, usually no comprehension of what VHS is.
Never get these VCRs for playback. At this late date, this sort of item is completely obsolete, too heavy to be a paper weight, not heavy enough as a boat anchor.
Get one of these:
