  The HP-85 tape problems have been covered numerous times in this and other mailing lists. You should search the archives for more details but briefly there are three serious problems with the HP-85s. 1) the rubber drive belts in the tapes rot and fail to turn the tape reels. This can cause the STALL error message. 2) The media falls off the tape and the drive sees the clear tape and thinks that it's reached the end of the tape and reports and EOT error. 3) The "rubber" drive wheel in the drive gets soft and gooy with age and fails to drive the drive wheel in the tape cartridge. These can also cause a STALL error.
