HP 98200A DC100 belts / Athana out of business?
« on: November 13, 2022, 04:24:52 pm »
Dear readers,

I was suprised that there was no search result in this forum about the topic.

Question: Did anyone buy more replacement belts for their HP tapes than needed? Or found a working replacement from another drive belt manufacturer?

The always ripped belt is exactly 24cm long 2mm wide and very thin (have to edit this in later). AccuPrint seems to have had some tapes, but replied: not anymore.

Athana's website is so old and they did not respond to me yet that I have to suppose they're out of business.

Why do I need them? I have the 8510B Operating System with TDR Option 010 on a set of two tapes, and wanted to send them to a HP computer collector (after baking the tape coating) who has working tape drives (I don't know who can do it yet) to save them. Otherwise I have to rely on the old eproms to last (didn't fire up the beast after it was sitting in some basement the last ~10 years), or get them out and copy them with the associated risk.

If a source for the belts was avialable, it would theoretically be possible to wind music casette tape (both .15") back in to play around with the tape drive. The old tape, as you know, is too brittle. The question to solve before is, what kind of tape coating works. I remember reading on a label it being a 300(?) Oersted tape, but what kind of coating would that translate to in music casette industry - if this was referring to the coating or just the erasing field, I don't know.
