I am trying to repair my old Tascam 688, but am awaiting result of biddiing on ebay for some TDK SA 90's. That is what I always used, many years ago. I don't have any new ones to use for testing the machine until they arrive. Can I use type I tapes, simply to check machine functions. They do play and wind OK. I am not bothered about audio quality for this at the moment. The tabs seem to operate the microswitches ok, but not sure if other issues come into play doing this?
