Excellent! Thanks for the suggestion Wayne! This may be the best option, as
the existing one isn't going to an easy fix.

Thanks Paul, handy to know!
I have a set of tapes that look to be in very good condition, with the
exception of the players capstan and the internal tape bands. Mine does
also look like it might have been expanded, so I'll see if I can identify
any upgrades.
Thanks also for the note about the HP
Northeast US roughly.
You may also wish to join the VintHPcom group on groups.io where a lot
of HP 98xx users hang out.

Howdy all!
I'm the new owner if one of the coolest "Calculators" HP ever made.
Everything generally works but I would need a new capstan (rubber is now
sticky) to use with the tape cartridge.
I am running into a hard time tracking down information on using it though,
so if anyone can help fill in

IIRC, there were two main models of 5150, and a few sub-models.
All 5150 were five slot. (5160 (XT) had 8 slots)
There was the "16-64KB" that had one row of 4116 soldered in, and three
rows of sockets. It could be purchased with those other three rows
populated, at a rather high price for 411
One last shot.
I have an RX Floppy disk unit. Worked fine until one
