So sounds like
1. get a 9825 (or find someone that has one locally)
Reason for a 9825 is it is the only one with a tape drive that will read
the tapes
Is this correct ?
2. prep the tape(s)
3. copy the data from the tape to a 9895A -- any ever do a emulator ?
4. read the data/run with a 68010 based 200 series .. will the original 300
work ?
I've not taken a DC-100 apart but have done many DC-300's I've got a box of
DC-100's that I don't care what is on them, I'll find it and use one of the
tapes as a test case.
Looks like I've got a long ways to go ....

Pete,
Those are DC100A tapes used in the HP 98X5 series computers.
The programs are not compatible with the 9000/300 series.
I couldn't see the tape number on the label but I think it's a 9825A/B
tape written in HPL.
Instrument software on this kind of tapes I've seen was written for the
9825.
You'll need a HP 9825 to read this tapes and copy them to a disk (8" HP
9895A).
The tapes are very fragile, 90% the belts are stuck to the tape.
And you need to warm the tape to about 50-60C to get the belt from the
tape without peeling of the magnetic layer.
After that the belt needs to be reconditioned (see my earlier mail) and
the tape may be needed to be baked (several hours in an oven at 55-60C).
After that you have only a few (1-6) passes to read the tape, before it
becomes badly readable.
Replacing and removing the drive belt will need some practicing (I've done
it).
When the programs are copied to disk it's possible to read them on a HP
9000/200 series computer with HPL for the 200 series.

Which will not run on the 9000/382 or other processors higher/later than
the 68010.
