Just obtained an M4 Data tape drive, model 9914 (800/1600/3200/6250)... just pulled from
working service...desktop enclosure... $50 bucks :)
I believe it's Differential, not single ended. I haven't kept up with PC
technology (hooking this to a PC). Is this older Differential the same as LVD? I believe
it had a centronics 50 pin connector labeled "differential". I'm wondering
what SCSI card I can use with this... Adaptec 2940?

Nope. I forget how Adaptec's HVD line is numbered, but LVD, wide, or
UW will NOT work with HVD devices, and will likely cause Magic Smoke to
escape.
And, of course, HVD adapters for PC have gotten Very Damned Expensive.

BusLogic BT-958D is an older HVD PCI card, relatively cheap and works well
with linux. I would not recommend any Qlogic based cards with linux as
the drivers SUCK. Adaptecs seem good.
There don't seem to be any 958D's on Ebay at the moment...

I happen to have, available for trade, a known good Rancho Technology wide
SE<->HVD converter (and a couple of 5Gig wide HVD hard drives). If the
device is not wide (and it looks like it is not), you can use a wide to
narrow converter on each side and just ignore the high bits.
Let me know if you want it,

Right now, in fact, there are three Adaptec AHA-2944UW Diff/Wide/Narrow SCSI cards at
'Buy-it-Now' for $45 each. Here's the links.

And here's a BiN on an HP adapter for $25. Granted, I have no idea if this will work
in a PC, and you'll probably need one of those Compaq wide-to-narrow cables to use
it...

Happy hunting.

No, I wouldn't even consider a new one, but even at $40-45, HVD is
still relatively expensive. I can reliably get an Adaptec 2940UW,
single-ended ultra-wide, for $10 or $15, or a BusLogic UW for $5-10.

Wow - I paid $400 for mine, and was happy to get it!

Mine runs with the Adaptec 14- mumblemumble on this laptop with a copy
of Novastore - reads and writes tapes just fine, but I have it mainly
connected to the SCSI port on my VaxStation 3100 - and it mounts, reads,
and writes just fine under VMS 7.1.
Mine has a sticky hub-lock solenoid - at the beginning of a session I
have to lift up the deck and give it a tweak - then it's good for the rest
of the time. I've lubed it and taken it apart (and the damn hub, too!)
and put it all back - same thing - so I just do the workaround and all is
well.
Let me know if I can help out with this - IIRC, I have the service and
operator's manual on .pdf somewhere...
Cheers
John
