The curious approach to "18pin" printing was twofold. One was to allow fast draft quality printing and the other was rugged high quality printing that could still punch multipart forms with a known reliable head. At that time there were a few 18 pin heads but they didn't have the long term life at sustained high print rates. Note, this is a 1984-5 design so understand that many printers at that time were of smaller or less rugged style or really imposing printers. The LA100RO is most valuable to businesses that still used wide pinfed (assuming you have the forms tractor) multipart forms. In the high quality mode it does print decently and the graphics printing is not as slow as some dot matrix were. Allison

Interlan ethernet transceiver units available

by auringer＠tds.net

More stuff uncovered. I have several (~5, actually) Interlan NT10 transceivers to dispose of. These clamp on to coaxial backbone ethernet cables and pierce the jacket (vampire tap) to make a connection. They have an AUI port to connect your equipment to. If you are interested in them, make me an offer for my time to box them up and take them to a shipper. If there is no interest, they will get recycled. I am still in Madison Wi. 53714 Jon Jon Auringer auringer at tds.net

Seeking Proteon P4100+ router manuals

I can't help you with manuals, but I will confirm that Proteon was indeed an independent firm in the 80's. During the early and mid-80's I was a member of Novell's technical staff during and had a good working relationships with several Proteon engineers. Novell, of course, had PC networking software and was working with just about any and all PC networking hardware vendors to make sure that there was a NetWare driver for their gear. At that time, Proteon had their own flavor of token-ring over twisted pair style hardware call Pro-Net. I don't remember the details or the transfer rates, but it was not particularly successful and later Proteon ended up joining the shift of the industry to Ethernet. Somewhere along the way, in the very early 90's, I think, they combined with 3Com. If I remember right, Proteon was located in Waltham, MA during the 80's. - Jared

anybody have any IBM 8525's?

----------Original Message: Date: Thu, 20 Nov 2008 01:45:19 -0600 From: "joe lobocki" <jlobocki at gmail.com> Subject: anybody have any IBM 8525's? hello, Im trying to find one of those all-in-one PS/2 computers that IBM had in the late 80s, some were under the "EDUQUEST" badging, but most were the all-in-one 8525, and for some reason those who are selling on ebay think they have one of the rarest machines in the world and charge as so, and it really makes me regret not grabbing one from the salvage pile when they dumped all the ones in 99 when i was in middle school. anyway, does anyone have one they are willing to part with, or know of a cheap source of them? thanks -Joe -----------Reply: You might have more luck if you ask on the Vintage Computer Forum (vintage-computer.com) Several hundred EDUQUESTs around, but don't know which model.

Hi, Will, I'm in NZ now, and I managed to easily disconnect my USAP subscription, but my request to add from gmail hasn't gone through yet. So could you do me a favor and mention on the list that I'm in Christchurch for a few weeks and would enjoy the opportunity to meet with anyone on the list who's in town to talk about computers, etc. Just have them contact me at this address. I check it frequently. Thanks, -ethan

FS or FT: HP75D and 82164A (HP-IL/RS-232C Interface)

by joachim.thiemann＠gmail.com

Hello, in an ongoing effort to thin out my collection, I've decided to sell or exchange some old HP bits that I'm sure are more useful to other members of this list. They should probably go to the same person, though the latter might be useful to some HP41 owner, too :-) HP-75D, with power supply, 8k ram pack, about 16 magnetic strips and one abrasive cleaning strip, and I/O Rom. I only have the manual for the I/O ROM, and the June 1983 issue of the HP Journal; that is the only "manual" I have for the 75D. I don't have the battery pack, I did at some point, but can't find it anymore. Some cells were dead, anyways - I think I kept the plastic parts, but it may be lost. It's fully functional (on AC power), but looks used (of course). Two of the feet pads are missing. I also have the 82164A HP-IL/RS-232C Interface, with power supply and manual, but I never had any HP-IL cables, so I could never test it :-( This one looks as if it came just out of the shipping box. I'd be happy to trade for a more modern HP calc (HP48SX or better) or interesting MIDI gear - otherwise I'm open to offers. Pic at http://www.ece.mcgill.ca/~jthiem/IMG_1916.jpg Oh, I also have an HP Omnibook 600C (working except the left mouse button) that I'm trying to let go. I'm in Montreal, Canada.

DEC Letterprinter 100 -- what are they selling for?

by js＠cimmeri.com

Are DEC Letterprinter 100's in nice, working, non-noticeably-yellowed condition worth anything at present? Or are they pretty much recycling fodder? Thanks, JS
