I have a 4951. It uses the same tapes as the HP-85, HP 9825, etc. IIRC
they're DC-100 tapes and you can use the same (40MB?) tapes that were
used in PCs.
Really? Didn't know the PC tapes would work in the older drives. Given
that the storage capacity of a DECtape and an old PC backup tape are
so wildly different, I didn't assume the media was compatible even if
the shell would fit in the drive.
You have to reformat them but yes, the OLD PC tapes work fine in the HPs.
You can also reformat and use DECTapes.
Right. That's what my boss used to do. I have plenty of 4951-formatted
DECtapes to last me a while (5-10, IIRC).
Just be carefull who you tell about that. The DECheads get real sensative to anybody
putting DEc stuff to REAL work. :-)
But check your drive first, you'll probably
find that it has the same
problems (melted tape drive roller) as the HPs usually do.
That's a common problem with all these drives. I've already replaced
the melted rubber in one TU-58 with tygon tubing. I can do it again.
Last time I checked (six months ago), the 4951s hadn't melted yet.
My 4951 is in storage but I'm pretty
sure that there's a operators
manual with it.
I have a operator's manual somewhere, too. I'd _really_ love to lay my
hands on a maintenance manual.
Me too. I have an option board in mine that had batteries on it that leaked and some
of the surface mount parts fell off. I'd like to get a schematic and fix it.
Fortunatly the machine works fine without it. I got the machine dirt cheap because of the
battery damage and all I had to do to make it work was to unplug that card.
