I am attempting to recover some files from a DECTAPE II cartridge.
They are in RT-11 format, so the most useful drive would be a TU-58.
Does anyone have a spare drive that they are willing to sell or at
least rent for a long time? The one that I prefer is a dual desk
top box with its own internal power supply and a 10 pin header on
the back for connection to an RS-232 channel so it can be connected
easily to a DLV11-J (or any other DL channel on a PDP-11 with some
wiring changes).
A TU-58 is normally standard with a PDP-11/44, so if the 11/44 is not
in a state to be rescued, that at least if there is a TU-58 available,
please contact me. They may also have been used with a VAX 11/780.

I do not have that model... I am using one from inside a VAX-11/725
with a custom power cable to tap from a PC PSU disk drive connector. I
sit the drive on top of a PeeCee with the skins off and the wires
disappearing into the innards of the box.

If you have a VT103 w/TU58, you could approximate the table-top TU58
enclosure. Additionally, they did come in the 11/750, but they are
bolted to the inside of the CPU cabinet and not a discrete entity
as they are in an 11/730 or 11/725. Didn't ancient HSC controllers
have a TU58 drive in them, for microcode patches?

Not as far as I know. The 11/780 came with an 11/03 as a console
processor and RX01 console media.
No matter what you get, don't forget to check the rubber puck for
gooeiness. Most of mine have turned to jelly and been replaced.
I have had good success with Allison's suggestion of using tygon
tubing from the hardware store. I bought 12" of it for much less
than $1 and I have yet to run out.

HSC50s booted from TU58 - not a pretty sight if you'd had a power failure
and needed to restart everything. Fortunately, the site I worked at had
HSC70s which booted of RX33s and even then booting seemed to take forever
when there was a horde of angry axe-wielding users just outside the
computer room :-)

Yeah it does take a while. Still got one of them, retired it from work last
year, not currently using it, but it's there.

LOL, replaced the HSC50 with a HSC70. Big improvement, but I have a dream
of finding one somewhere
with the caching kit in it so I can add it to ours. SDI drives (RA7x/RA9x)
are a bit slow at the best of times.
Regarding HSC's, I've often wondered if it was possible to get something
other than CRONIC to run on them....

I get them too, but usually only if the NetWare box goes down, if the
mail/web system (Vax 6000-440) is down it takes a little longer for the
phone to start ringing, usually by this time I have it half booted and am
waiting for the 'improperly dismounted' drives to remount. (Doubles the boot
up time!) Mind you, in the middle of the day when there are up to 5
computer rooms doing web searches and the proxy is off line, it can get like
that very quickly!
I've found and fitted a battery backup to it, but the batteries are
knackered, (well they are getting on a bit) going to pull it back out and
see what they are and replace them, make for faster restarts!

I have added a page to my site dealing with the TU58. Far from complete
