Cool. Thanks for sharing that! > Already 2 TU60 have been repaired with the above. TU60 are direct-drive digital cassettes. https://www.pdp-11.nl/peripherals/tape/tu60-info.html The TU58 uses DC100 cartridges. http://www.hp9825.com/html/dc100_tape.html I had a boss who recycled some DEC TU58 for our HP 4951A serial analyzer. It can format cassettes, the TU58 cannot, so it's a one-way-trip. -ethan
