Hoard of elderly HPs

[Roger Plant]

I've just managed to get a quick look at my stored HPs and found also two 9915A machines that I had forgotten about.
Both have tape drives and one has a 82903A 16K memory module in it.
I had a load of those at one time and thought I had sold them as a job lot for the tape drives. If I kept back two of them then I must also have kept the 85 desktop used to program them.
They have their own style interface plug in cables and I think I have some of them in the store.
The tape drive in the 9915 I have just checked has a very sad looking tape drive wheel but I could use it as a pattern to make new ones.
But as I said previously, a dimensioned drawing of the tape wheel would make that job much easier.
If I can make one then I could make many more if there is a demand for them.
