Hi all,
A longitudinal study I am vaguely connected with have discovered
archives on tape for one of these magnificent old beasts:
http://www.columbia.edu/cu/computinghistory/701-tape.html
Do you know anyone who could read them? I've suggested IBM's mainframe
division or the national computing museum. Any other thoughts or is it
time to break out the oscilloscope?

I think just about your only chance in the UK is to contact the
National Museum of Computing at Bletchley Park. They have connections
with the IBM archive/collection.

In California, there's the Living Computer Museum:
http://www.livingcomputermuseum.org/
They're connected with Vulcan, founded by Paul Allen (of Microsoft),
who keep old machines running for exactly your type of problem:
http://www.vulcan.com/
But I suspect they're not cheap.
Do not, under any circumstance, simply try to make a drive and read the
tape(s). They may be suffering from "sticky shed syndrome", whereby the
oxide falls off the tape as soon as it passes over the head. Many big
audio-tape brands sufer from this issue, and it's a major hazard to
old audio recordings. Be prepared for the tape to destroy itself on
the very first reading:

My googling suggested that sandforce were pure poison. As I understand
it these have fatally flawed firmware, and it is not a question of if
they will fail but when.

My only sandforce product died within 3 days of installation.

It should possibly be noted here that Intel switched to Sandforce
because their previous controller was even worse.
I had an Intel 320 SSD. Worked fine for about a year, then one day
refused to acknowledge that it was more than 8MB in size. All data on
the drive was gone. Google for "Intel SSD 8MB bug", and note that the
alleged firmware fix does not, in fact, stop the drives bricking
themselves.
320 series drives *will* fail completely, irrecoverably, and without
the slightest warning. If you're unlucky enough to have one, back up
everything on it NOW and then pre-emptively smash it with a hammer, or
give it to someone you hate.
I've been very happy so far with my Samsung 840 Pro, however.
Cheers,
Rayner
