Hi all, I've come to the conclusion that it's time my PDP11/73 went to a new home. Not a terribly easy decision to make, but I just don't have space to even get to it to switch it on just now and I'd rather see someone else get some use out of it. Anyway, here's the spec: PDP11/73 in a large Baydel cabinet with a 40M-ish MFM drive RX02 floppies 2 x RL02 plus a spare RL02 2 x CIT101 terminals VT520 terminal VT220 terminal LA36, spare ribbons and paper spare boards including 11/03 bits, a couple of opto-isolated I/O boards and some ADC boards DEQNA about a dozen RL02 packs large box of RX02 disks RT-11 V5.2 manuals Pick up in Glasgow. You'll need a van, although not a very big one, to shift it. A large estate car would be too small unless you broke the rack down into panels - a PITA, I've done it before though. Mail me on- or off-list if you're interested. Gordon

Hmmm . . . that technique might work for my 2N2/256 BSCP project! It also occurs to me that the machining could be done with the drive mechanics, provided it's rigid enough and you take very light cuts. You would fabricate a cutter head that bolts in the same way as a R/W head. To take a cut, you just tweak the adjustment screw(s) and turn an additional "feed" screw to cut the track the right width. Heck, you wouldn't even need the feed screw. Make the head so it can slide laterally a millimetre or two, then you could move the cutter head back and forth by hand, the same way the Fonly lathe works. It also might be possible to just lap the R/W heads in with a tiny amount of jewer's rouge, then carefully clean all the grit out and readjust the heads to give the right gap. -Bobby

Seeking Proteon P4100+ router manuals

by dave＠mitton.com

Sellam, et. al. As others have contributed, Proteon was an independent network vendor in the 1980s. I'm a little unclear what became their corporate fate, (I forgot about DEC buying source code) but they did eventually come apart due to market forces. They were an early token ring manufacturer, with their own product. When IBM pushed their technology into the IEEE 802.4 standard, they adapted with the market. They also made multi-protocol routers, and since they weren't Cisco, Digital did do some work with them. I had a 4100+ and a 4200 in my development lab. Unfortunately for you I don't think I took any of that stuff home. I was the technical lead/architect for a DECnet Token Ring Data Link specification. As part of that program, I also specified how to interface DECnet-DOS/Pathworks on to PC token ring devices. We worked with Proteon to put DECnet routing support into their routers, and I think they are whom we got to OEM an 802.4 Qbus NIC card for us. (with DECnet VMS support!) This was all to deal with the pressure IBM was putting on the PC and networking business at the time. (my memory is fuzzy on that now.) God I'd love to see what happened to the customers that swore that token ring was so superior to Ethernet that it was going to rule their networks going forward. IBM put some interesting crocks into their LAN chips wrt multicast addressing that really messed things up. I'm glad to see that chapter of history closed. I may be able to make some personal contacts to see if they have anything around. I woundn't be suprised if there is a Proteon old users/collectors group out there somewhere.

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

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

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.

keypunch equip on govliquidation

by brian＠quarterbyte.com

Looks like the lot has 4 brand new 029s and two used machines, at least one of which is an 026. Somebody go get these! Or, do what I did in 2001 when a lot came up, and get a group together to buy them and divvy them up. These don't come along that often. Looks like there is some interesting old radar display gear in there too, which some military buffs would probably want. Are those scope hoods made of Bakelite? http://cgi.govliquidation.com/auction/view?id=2037010&categoryId=c7149 There's a whole bunch of other stuff in the lot, but you can call the DRMO staff and see if they can either keep and relist the remainder, or give it to a surplus dealer. There are usually surplus dealers hanging around happy to haul off whatever doesn't sell or what gets abandoned. It's the logistics of shipping and dispersing the stuff that's painful. Looks like the four new 029s are crated, the 026(s) are sitting on pallets, and they'll have to be padded and strapped. In the 2001, I used freightquote.com and scheduled a pickup & had the units sent to the people in the group. FYI I just looked at the bills of lading, we listed the factory-crated 029's as 520 lbs each, and the 029s on pallets as 310 lbs each. At today's rates, you should be able to ship a palletized unit from Ohio to, say, California, with a liftgate delivery, for about $250, and a crated unit for about $350. I'd be interested to know on or off list what happens with these, punched card stuff is one of my areas of interest. Brian

Interdata Model 74

by toby＠coreware.co.uk

Hi, A couple of years ago I bought an Interdata Model 74 CPU and I'm pondering what to do with it. I'm leaning towards rebuilding it to working condition next year and I was wondering if there are any other Interdata owners out there? The machine is in generally good condition, although I have has no power supply with it so will need to find or build something suitable. Unfortunately I have no documentation and so if anyone has any engineering documentation for these machines it would be a great help. Bitsavers has some details on the Model 70. Does anyone know how similar the Model 74 is to the 70? Thanks, Toby -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

I'm not likely to ever find another .029 in as new condition, presumably with the program drum which I've been outbid at silly money on eBay. Ohio to California is quite a long way, so maybe 2 or three times as much for shipping across the Atlantic, would be worthwhile for an AS NEW one, but not for spares. As long as it can work on 50Hz mains frequency, voltage no problem. I would also be very interested in an old control drum if there's one in the .026 and it gets scrapped. The printing mechanism too maybe if its not too difficult to remove. My alternatives are to restore my IBM 836 keypunch (like an 026 but with more bells and whistles) or to resurrect a spare online punch and interface it to my Mac. This will take many hours of effort, though it would also get me a fairly slow card reader. The mechanism is an IBM design made under licence by British Tabulating Machine Co (BTM) and its successor company, International Computers and Tabulators (ICT), the main mechanism of which seems identical to the one on the IBM 1401 restoration web site. Old keypunches just don't seem to come up any more in the UK.
