Hi,
I've been regretting not keeping my original Hazeltine terminal many
year ago.
Does anyone have one, broken or working, they might be looking to sell
or trade?
Mark

Excuse me?
I worked with 4341 and 4361 systems at UChicago, and a pair of 4381s at
Stanford. There wasn't a water pipe to be seen. I think that you have
no idea what you're talking about.

Many thanks Fred for correcting me and for the mini-tutorial.

OK, I'm sure there would be some mileage in tools that could use this feature. I guess not all PC FDC chips would have this capability though. (FWIW I am a fan of the Adaptec 1542 cards with their built in FDC, two types depending on model but both OK with FM disks).
Coming back to LIF disks with bad tracks, as I wrote above I am a fan of HPdir, and am using a PC with an HPIB controller and 82901M floppy drive, so avoiding any use of the PC's FDC.
I've got a further query on the 82901M and 9121 drive which I'll raise in a new thread. Regards,John
I've got a pdp11/34 in a BA-11L mounting box, and I'm trying to find out
what rack hardware I need to rackmount the beast. If anyone has info
(part numbers, etc), or can point me at a resource (or even a supplier),
I would much appreciate it.
Thanks.

A friend of mine has a serie of such tapes
Six 9 track, 1600 Bpi, tapes, ( large ones : 2400 feet )
Labeled 1992 / 1993 SPOT2
Any guess what is / was "SPOT2" ???
eBay item# 230917408086.
This is one of Sellam's lost items and it's interestingin that it
appears to be an S-100 machine made by HP. The cabinet definitely looks
like HP, the boards not so much, although a couple seem to have
gold-plated traces that look HP-ish. I've never heard of this machine
before, and I can find no information about it on the 'net. I'venever
heard of HP making an S-100 machine, it seems out of character for them
:). Anyone have any insights here?

I asked the author Benj Edwards <editor at vintagecomputing.com> if
anyone had a copy of the data - so far, no one said they had it.
I thought it would be fun to recreate it from the original deck.
