pdp11/34 restoration : question & items sought

by jos.mar＠bluewin.ch

My recently acquired 11/34 has a few missing parts : the boot proms of the M9301 and the M7850 parity board. It does have 16K mos memory and the full programmer panel. However, when I fire it up, I cannot halt the processor, the RUN light stays on. Could this be due to the missing parts ? And of course, to complement the system, I am looking for the following parts : - the missing items of course - an unibus RL11 controller. Are these rare ? - Some more memory.

Cleaning house (FS/T: lots o' stuff)

by pat＠computer-refuge.org

I'm trying to turn my apartment back into an apartment, instead of the warehouse of machines it currently is... so I'm trying to get rid of some of my machines that i've got multiple of, or no longer have any real interest in. Here's a list of what I'm offering. I'll be putting more stuff on eBay (userid: pfinnegan) but it's mostly going to be OT machines. Also, I purchased an MMJ crimper and a bag of MMJ ends... in order to help subsidize it, i'm offering length-to-spec MMJ cables. If anyone is interested, I'm asking $5 per cable for up to 20ft plus shipping ($3.85 for Priority Mail). If you want multiple cables, ask me and we can work out a deal. I can also do MMJ to RJ45 cables, but won't do RJ45 to RJ45's... network cables are cheap enough. Now, the list: + IBM RS/6000 410: 80MHz PPC601, 2GB HDD, 32MB RAM, CDROM, graphics card (13W3 connector), 2.88MB floppy drive $15 + shipping + IBM RS/6000 410: 80MHz PPC601, 2GB HDD, 64MB RAM, CDROM, graphics card (13W3 connector), 2.88MB floppy drive $20 + shipping On both of the above machines, I don't have the key, but I've removed the pins from the locks so they can be operated with "anything"... + Sun SparcStation 5, 70MHz, 96MB ram, CDROM, floppy, 2GB HDD, CG6 501-2981 narrow scsi/10BaseT ethernet card $10 + shipping + Sun SparcStation 5, 85MHz, 128MB ram, CDROM, floppy, 2GB HDD, CG6 501-2981 narrow scsi/10BaseT ethernet card $15 + shipping + Sun SparcStation 5, 85MHz, 128MB ram, floppy, 2GB HDD, CG6, 501-2981 narrow scsi/10BaseT ethernet card $20 + shipping + DEC DECstation 5000/200: R3000/25MHz, 40MB ram, PMAG-B framebuffer $10 + shipping + DEC DECstation 5000/240: R3400/40MHz, 64MB ram, PMAGB-B framebuffer $15 + shipping + DEC 3000/300LX: 125MHz 61064 Alpha, 32MB RAM, 4GB HDD $20 + shipping + DEC 3000/300: 150MHz 61064 Alpha, 64MB RAM, 4GB HDD $25 + shipping + DEC VAXstation 3100 m38: 2 memory boards (16-24MB ram), 500MB HDD, OpenVMS 7.2 installed (Hobbyist version from Montagar) $15 + shipping + 4x"MBR Systems, Inc" S-100 systems - various CPU, RAM, some A/D cards, a video/keyboard interface card, in a 4-5U rackmount case with the keyboard mounted on the front. Most have 40-48kB ram and some EPROMs shoved into a 64kB static ram card. $20 ea + shipping + SGI IRIS 4D/80 (030-0122 / IP4.5) CPU board with 16MB ram - I no longer had the room for the machine, so it went away and I kept the cpu and some VME cards from it. $5 + shipping + 24x"66 block" telephone connection blocks wired together as 100x2 connections... I picked these up pretty cheaply for no good reason : ) 3 for $5 + shipping I prefer shipping via FEDEX, is from zip 47906. I'll take payment via PayPal or Check... I'll give you the address when you ask me for the item (if you've won it). If you prefer to trade me something for the above, here's what I'm looking for: + Unibus (w/toggles) PDP-11 (this is worth multiple items, of course... I'd probably even be willing to pay something for this) + Parts for above PDP-11 + Seagate ST-251 and ST-225 hard drives (working) + DEC RL02 disk packs (non-red shock indicator) + KA-660 CPU board and cab kit for a vax 4k/200 (S-handles) Pat -- Purdue University ITAP/RCS Information Technology at Purdue Research Computing and Storage http://www.itap.purdue.edu/rcs/

Hey all you HP mini nuts, look what showed up on ePay a couple hours ago: HP 1000F complete with S/W Manuals & spares eBay item # 2777501482 "This is a complete HP 1000F mini computer with 2648A graphics terminal, two 120MB disk drives and several disk packs, including RTE IVB grandfather disc. [...] Pick up must be arranged by buyer at storeage facility in Houston Texas, packaging not available." Best of all, Buy It Now is only $250! I have no affiliation with the auction. I just wish it were a tasty DEC mini similarly configured, and up in the Northeast somewhere... Good luck and happy new year! --Steve.

Commodore Haul

by rcini＠optonline.net

Hello, all: Today I picked up a small cache of Commodore 64 equipment. That in and of itself is not notable, but this guy has the entire Infocom games collection with game cheats *and* the complete Commodore Compute! and RUN magazines. I really wanted this for the magazines. I will be taking a complete inventory in the next few days and if there's anything else interesting, I'll let everyone know. Happy New Year to all.

AM26LS34 line receiver chip

It's the same pinout as a 26LS33, in fact it's almost the same chip, but with higher input resistance (20K) and higher hysteresis, and it doesn't have the internal failsafe (output on a 26LS32/33 is guaranteed to go high if both inputs are unconnected). -- Pete Peter Turnbull Network Manager University of York

Not having the parity board simply means that parity errors won't be checked or detected. Missing the PROMs won't upset anything (except if you try to boot it, of course). Your problem is most likely to be a missing NPR link on the backplane. Common problem; it's caught me out at least once. Make sure there are no empty SPC slots; all should be occupied by dual-height grant cards or devices that pass NPR, or a small grant card with the NPR link made amongst the wirewrap -- between pins CA1 and CB1. The small grant cards only link the four Bus Grant lines, not NPR. > And of course, to complement the system, I am looking for the following > parts : > > - an unibus RL11 controller. Are these rare ? > - Some more memory. Neither of those should be *too* hard to come by. Neither of them are rare. What's "missing"? Just the PROMs and the parity card? -- Pete Peter Turnbull Network Manager University of York

Signetics Data Book

The "MC" > sounds more like a Motorola part. Is there a date code on the part? How old are the books? It's moderately recent (late 1990s), and I'm fairly sure it's actually second-sourced by Philips from a Motorola original (now obsolete, of course ;-)) -- Pete Peter Turnbull Network Manager University of York
