Hoard of elderly HPs

[Roger Plant]

98228A disk ROM? I will have to look. Not long before I put my 9825(s?) into storage I acquired some more bits including some 8" floppy disc units ex-HP test department at Winnersh UK.
I can remember trying to run my original 9825 from those discs without success.
That leads me to think that said ROM was missing. I also have a memory of a second 9825 that I had at that time, possibly from the same source, so there is hope.
My memory of exactly what I have in storage is a bit vague as I put them in the store about 1998, (year that is not HP part#)
We will all have to be patient and wait until I can get at it all, hopefully this weekend, life and other things permitting.

The reason I got the 8" floppys was because I knew the 9825 tape drive had a limited life due to the deterioration of the tape drive wheel.
So as a second string to these thoughts, does anyone know of a source of replacement tape drive rubber wheels for the 9825?
