Romania: complete PDP-11/93 on offer for $

by nigel.d.williams＠gmail.com

As I have a webpage (www.retroComputingTasmania.com<http://www.retrocomputingtasmania.com/>) describing my attempts to resurrect an PDP 11/93 I was contacted by a company from Resita, Romania who have just decommissioned an 11/93 in operation since 1993; it includes 5 DEC VT terminals and a non-functioning line printer. They describe it as a "PDP 11/93 193 QZ-D3, model HB9642- JB" They are inviting offers for this system, in their words "...for a fair price proposal.". Cellphone quality pictures sent to me are linked here: http://imgur.com/Hj6fR http://imgur.com/CJU3q http://imgur.com/docPG For my curiosity can anyone tell me what the cabinet on the right is likely to contain? is it disk expansion? Contact me off-list if you want to see the original emails. Please contact Zoltan Korka (zkorka AtThisDomain resitareductoare.com) www.resitareductoare.com

Free Apple Mac LC, London

by lproven＠gmail.com

Anyone want to give this a home before I recycle it? Original Mac LC - 68020, MacOS 6-7.5. Doesn't boot, but that might be the dead battery. I've checked; all my spares are dead, too. 40MB SCSI hard disk & I suspect 2MB RAM / 256KB VRAM. http://lowendmac.com/lc/macintosh-lc.html I might even deliver if it's inside the greater London area. Ask me nicely! Keyboard & mouse can be supplied with it. You've very welcome to a monitor too, but if you want one of them, you'll have to collect it. -- Liam Proven ?

Origin of the term minicomputer (was Re: PDP-1 as ...

by c.murray.mccullough＠gmail.com

It?s my understanding, and I stand to be corrected, that mini, hyphenated or otherwise, simply meant a small computer system that preceded the microcomputer era. Granted this, the term means different-things-to-different-people, the consensus seems to be that the term mini means smaller than a mainframe and matches comparable words from the 60?s, i.e., mini-skirt, et al. As a(n) historian I treat it as a cultural phenomena rather than just a purely technical or technological definition. Whether purists agree is indeed debatable! Murray--

Mostly OT: Looking for Manual/Schematic for Wavetek 1901C

by derschjo＠mail.msu.edu

Snagged a Wavetek 1901C last week. This is a 12" oscilloscope display (X/Y+intensity input), I was hoping to use it as a point-plotting/vector display for a couple of little computer projects of mine. (Or maybe just hooking an Asteroids board up to it... :). It's in pretty good shape (has more screen burn than I think I've ever seen in a few spots, though.) I fixed a couple of cold solder joints and it's now mostly working, except something appears to be going slightly wrong in the Y deflection or amplification (it's getting clipped/distorted depending on the gain and input intensity). Anyone have a service manual or schematic for this thing or know good sources for such things? Thanks as always... Josh

Sure you meant "terabyte" not "gigabyte". The 2 TB drives are certainly more popular and common because they're getting close to $100. - John

BOUNTY: HP/UX 11i driver development

by doc＠vaxen.net

This is a bit off topic, I guess, and a repeat, but ClassicCmp is still probably the best place to ask. My company runs a bunch of HP83000 mainframes (F330 models) in product testing. We're tied to Agilent SmarTest v5.x-6.03 running on HP/UX v10.20 for test vectors. SmarTest interfaces with the test frame via an Agilent-branded fiber optic PCI adapter. The card is marked E2777B, p/n A3850-0583. It's a buffered serial adapter on a PCI bridge and that's all we know about it. SmarTest will run on HP/UX 11i, but the interface drivers will not load. We don't have source to the drivers in question, the card itself is, as far as we can discover, entirely undocumented, and neither HP nor Agilent has any interest in maintenance or further development. My company will pay a fair boatload of cash for an 11i-compatible driver. If you're interested and have the background & skills to tackle this, contact me off-list. Doc Shipley

Given the lack of technical expertise in Washington, this suggests a much earlier origin of the word. Tom

How about Series/1?

by trebor77＠execpc.com

How about Series/1? The Series/1 was the first entry by IBM into the minicomputer market as such. I just happen to have one sitting in my Basement. Brought it home around 1992 but never got it up and running. Should have added a 110 Volt 30 AMP Circuit but didn't. Its a 4952/4953 Half Rack W/a 9Meg HD setup for 110 Volts. Plus I have a external Floppy drive that used to work. I had an IBM Guy convert a 4955 Model E to 110 volt but I also have to original 4952. I plan on firing up the individual components through my Lab-Volt with a variable 120 Volt 3.5 Ampere Output if that will work without blowing something. "Any Thoughts Anyone???" Anyone out there running a tape drive setup that could read 6250 10" reels. I have about a Dozen, mostly backup tapes from the Working system. One is an IBM Diagnostic Tape. Maybe I can get in running. Going out west for a couple of weeks to Pan out some Gold flakes. A couple of Ounces will give me some cash to work with. Been retired since 1996 so Income is sparse.

need 35 P112 preorders

by dgriffi＠cs.csubak.edu

So far I've gotten only four P112 kits preordered. I need at least 35 of them preordered to get the thing rolling. Paypal will only allow me to do refunds and get the fees back within 60 days of a payment. 60 days after the first preorder is October 11. Because of that, I'm moving the preorder cutoff date to October 11. If I can't get enough preorders, all money will be refunded. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?
