I have oodles of 1/4" QIC cartridges - the big ones, as used in old Sun, SGI, and other early workstations. Anyone need them? I do not, and I would rather not scrap them. Most are used, unknown condition. How about as many as I can stuff in a large USPS flat rate box for $20? Please reply off list. -- Will

Burroughs B80 in NJ

by cclist＠sydex.com

Just passing this one on; if you need to contact the owner, his email is: Resnickshardware [[at]] gmail.com ------------------------------------------------------------------------- I have an old Burroughs B80 in a building I own. It seems to have all the parts, there is a printer and some floppys. I am interested in selling it to a collector perhaps, or a museum. Any idea what it's worth? Or other ideas where I could sell or get rid of it? I'm located in NJ.

For sale: HP 64110A "portable mainframe"

by ARFINK＠stthomas.edu

I have a nice HP 64000 series computer for sale. I rescued it from a surplus shop and fixed/cleaned it up a bit. I don't know much about it, and would like to pass it on to someone who does. Here is a copy of the post I left on the vintage-computer.com forums: For sale: An HP 64110A "portable mainframe" computer, used primarily for doing design work and in-circuit analysis and emulation. It's still considered to be a fairly competent diagnostic and development tool. Not to mention it looks awesome. This thing has been tested by me to the best of my ability and seems to be in full working order, but it's huge and I really am probably never going to use it to it's full potential. It comes with the optional "backpack" pouch attached to the top of the unit. It also comes with a large amount of cables and probes of various kinds. It has 5 different "pods" which can plug into the back of the unit. I am not familiar enough with this computer to be able to say what all the cards inside of it do. It also comes with a number of floppy disks, all of which work and have data on them. I am fairly sure some disks needed for doing compiling/text editing/terminal use are missing. However the boot disks and timing disks are there and work. If you know what you're looking for and can direct me, I'll be happy to do whatever inspections/photo taking you need. The machine does have a few small defects which I will list here: -The plastic screen cover has gotten a little bit discolored/foggy in one corner, which makes the screen look slightly blurry, but in my experience the screen is still very readable. -the keyboard hinge has come slightly loose on one side, but generally this is not a problem when operating on a table or in the "upright" mode standing on the floor -a couple of keys are slightly gummy in operation, and a good cleaning should fix this -there are some fairly normal scratches/scuffs on the case, probably because this thing is heavy and some engineer many years ago was forced to drag it across the floor. -and lastly, I haven't taken the time to thoroughly clean the thing, so it's fairly dusty inside I am looking for a some things I can get in trade for this beast: -A compact flash drive card for Apple II (CFFA, etc.) -Other Apple II things, especially IIgs stuff -Tandy model T things (ROMBO, NadsBox, TPDD 1 or 2) -Neo Geo MVS hardware (kinda a long shot, but hey) -what have you, just ask if I'm interested I would gladly trade this whole setup for a MicroDrive card for Apple IIgs. I accept PayPal if you aren't interested in trading. For people making offers, I am thinking somewhere in the price range of... a MicroDrive card. So $150? Let me know if you think I'm way off. One final thing- this beast is very heavy. You'll be paying shipping, which I have no clue how much it'd be because I'm not exactly sure how much this thing weighs. http://www.vintage-computer.com/vcforum/showthread.php?t=17278 http://picasaweb.google.com/arf.at.sjv/HP64110APortableMainframe# If interested, email me: arfink (at) stthomas.edu or send me a PM via the vintage-computer.com forums.

If you have a machine which still runs ClarisWorks, you should be able to save this data in MacDraw II format which MacDraft 5.5 can read and save. Possibly 5.6 too, but not 6.0, though that isn't released yet. There was just too much code to maintain for reading old files, and the alternative of using 5.5 (and 4.0 for REALLY old files) is still there if you can get access to a PPC/68k Mac. If you have used blends they won't come through, but schematics should be fine. From MacDraft you can save them as PDFs, which Illustrator will read if you can stand the price and the user interface. > > Alternatively, is the file format definition out there in public, so > I might > write a conversion program some day?

TU56 fun and games

by IanK＠vulcan.com

We've been working to connect a second TU56 to our PDP-8/e and TC08. Unfortunately, our second TU56 had been configured for a TD8-E. The good news is that we surmounted our lack of a M531 negative bus converter module - by making our own. The module worked partially (it did boot OS/8) on its first test, but further testing discovered one missing trace, which was easily ECO'ed. With that in place, I discovered that our second TU56 had a defective M040, and fortunately we did have a spare to replace that. Each TU56 runs appropriate MAINDECs successfully. The bad news is that we still don't have two TU56s on our PDP-8/e. The extant TU56 and TC08 documentation (thanks, Bitsavers!) aren't particularly clear on this, but the cable that connects the TC08 to a TU56 is NOT the same cable to 'daisy-chain' to another TU56. The TC08-TU56 cable, 70-6223, has several crossovers on the paddles - it's not A to A, B to B, etc. The TC08 documentation *hints* at that, but only states that connecting two TU56s requires a "M908 to M908" cable. The M908 is the paddle itself. There are at least two cables made using those paddles. The correct one to connect two TU56 drives (and I finally thought to confirm this in the FSTM) is a BC02X, which comes in various lengths. It, too, has M908 ends, but the wiring is direct, A to A, etc. (except for four low-value resistors in four of the lines). We do have a 70-6223, and I suppose we could rewire it - but I really really hate to do things like that. Frankly, I'd rather make some M908s. But I'd really like to find an original BC02X, if anyone has a spare in any length. Please contact me privately if you have one and would be interested in making a deal. Hey, we have some more M531 replicas.... Thanks -- Ian Ian King, Vintage Systems Engineer <iank at vulcan.com> Living Computer Museum A project of Vulcan, Inc. http://www.livingcomputermuseum.org

ASR33

by iamvirtual＠gmail.com

I have finally acquired a Teletype ASR33 for my PDP-11s (/20 and /10). Is there any chance of damaging the console port of my PDP-11/10 when I connect directly to the ASR33? Should I use some sort of electrical isolator board between the TTY and the port? Is there any way of testing the ASR33 prior to connecting to the 20mA port? The TTY seems to work fine in local mode. I have not yet tried line mode yet. What is the connection diagram between the 9 pin terminal strip on the TTY to the DEC console port? Thanks for any information you can provide. --barrym

wanted: teletype m43 paper tape schematics

by ronan.scaife＠dcu.ie

Dear all, we are trying to get an ASR43 paper tape unit back to running condition. The front panel punch advance button now works, punching sprocket holes. This seems to have been a problem with the connector to the circuit board, and switching the pulley from 60Hz to 50Hz. I now really need access to schematics for the circuitry to try to work out the problems with the reader, which will not advance. A scan or purchase would be acceptable. Best Wishes, Ronan Scaife, DCU, Dublin, Ireland --
