Hello. So it is happening. Finally. What a relieve. I am giving away my (almost) entire classic computer collection. Free of charge (almost). But local pickup only due to health reasons. Read: Due to a physical disability I am not able to ship any computers. Location: Kaiserslautern, Germany. Almost because I will keep my beloved SPARCstation 1+, my SGI O2 and a few spare parts for sentimental reasons. I am still tempted to keep a QBus with a LSI11 and MicroVAX III... Anything else has to go. I don't wane make a profit out of it. I want the stuff go into good hands with absolut minimum effort at my side. As compensation I only ask for your help to get rid of some other stuff that has accumulated over the years. (Loads of disk, CDROM and tape drives. Cables, adapters, expansion cards, RAM modules, ... and some junk in my basement. More cables, 14" VGA monitor, glass-TTY, 19" rack mounts, empty boxes, ...) Either you take some of the junk with you, or you help me bring the junk to the nearby recycling center. I don't care, as long as the junk is gone. I may also request your help to rearrange existing or install new furniture in my appartement. (My desk uses the Sun 3/260 as support...) You want it all? Perfect. Rent a moving truck. Come and get it. You just want some pieces? Fine. Come, get what you want and take some junk out of the pile. The more nice stuff you take, the more junk you have to take. (Sounds worse then it is.) Almost complete list of stuff available below. Almost all stuff can be picked up and transported by a singe, strong person. Only a few pieces will require an additional hand, that I can not provide my self due to health reasons. Contact me off list with your machines of interest to get things arranged. Rationale: I haven't done anything with this stuff in 15+ years. After 15 years, I am quite confident that this will not change. I tried to get back into it in 2010 by acquiring a PDP-11/34A. After a few weeks I lost interest and now it is sitting partly disassembled and waiting for repairs. (The PSU bricks need new electrolytic capacitors...) Sitting there for 15 years. Untouched. I haven't really read any postings to this list in 10+ years. I am basically only still subscribed to nag myself to write this email. For me, my machinery is like books that I have read. I had a lot of fun reading those books. I learned a lot out of them. Most important are the people that I got to meet via them. Like this very mailing list and the legendary VAXpower meetings... :-) But now I know all the books. There is nothing new to discover. The books just sit there on shelves, collecting dust. It reached a point where all this stuff is getting in my way to live a happy live. The collection has become an obligation, a burden. Especially as: At the end of 2009 my back broke and I needed an emergency surgery. Now I have to be very careful with lifting and carrying stuff. I don't move anything over maybe 6 kg anymore. (That is 13ish pounds for you imperialists. ;-) ) This is also the reason why I can not ship anything. I am simply not physically able to package the stuff and bring it to the post office without risking breaking my back again. And when my back brakes again, I may end up in a wheelchair. I escaped that just barely when my back broke initially in 2009... Needless to say that this physical damage also caused mental issues. I will not take any risk breaking my body again. Also: I live in an old appartement building. My landlord will renovate the appartement that I rent in late summer 2026. I may move out of this appartement into an other one in spring 2026, so that the appartement is uninhabited during renovation. I will not move all of this stuff to a new appartement. And if I don't move, I wane get rid of the collection anyway. It will ease the renovation process a lot. Anything that is not already gone when the renovation starts, respectively on moving day, will be recycled. If this means the PDP-11/34A goes into the dumpster to be shredded, than it will happen. Machinery: DEC PDP-11/34A + RK05, optionally in low boy 19" rack. Shares a RL02 and a Cypher 9-track Pertec tape drive with the 11/73. Tektronix 4000-something storage tube vector graphics terminal. I think I still have the accompanying Tek printer. Originally part of the 11/34A system. DEC PDP-11/73, the "franken-11" I pieced this together over time in a BA23 desk side box. Runs 2.11BSD. Has 4 MB RAM, 2 x MSCP ESDI disks (IIRC 150 MB each), TK50, RL02, SMD and Pertec adapters. Comes with a 9" 1 GB E-SMD disk. Shares a RL02 and a Cypher 9-track Pertec tape drive with the 11/34A. DEC VAX 4000-300, upgraded to a -400 DEC VAX 4000-200 DEC VT1300 2 x DEC VAXstation 2000 (At least one has patched ROMs to boot SCSI.)

It has no model number on the front. It looks like a DS20E. I have never, ever even powered up this thing.) Tektronix 8560 Multi-User Software Development Unit This is a DEC PDP-11/23 CPU in Tek box. It runs a customized UNIX V7. At my parents place there should still be MicroVAX III MicroVAX 3500. 2 x 9" NEC E-SMD disks, 1 GB Tektronix 4000-something text terminal with storage tube. Additional logistics will be required if you wane retrieve this stuff.

[OT] Digikey's project of the week is impressive

by me＠scifidan.com

A dude decided to do a hackodore 64 laptop in the most expensive way possible, but it's a beautiful result. Nice design ethic. I don't typically share youtube links but this one is a nice exception. https://www.youtube.com/embed/H5QQ0ECfwyE I hope this inspires perifractic into doing a c128 laptop after their new fpga64 ships.

Re: VAX and OpenVMS

by Peter Ekstrom

Just to tie a knot on this.... The MV 3100 is working great. I did replace the RZ25 drive with a ZuluSCSI and have it emulating a couple of RZ25s. I have VMS 5.3-1 up and running. I used the licenses from the OS that was running on it. I also have it on my DECnet network with my PDPs. The PSU looks great and the battery is not a problem either. The CDROM drive I got works great in an old Sun 411 enclosure attached to SCSI-B. I haven't used the TZ30 tape drive yet. I am going to see if I can treat the tapes I have to some time in the dryer and see if that helps. I think the surface of the tapes has softened and is leaving residue on the r/w head. I have read of some folks having success with the dryer. We shall see. But for now I am quite happy with it. Thank you everyone for all help and advice! - Peter On Mon, Dec 1, 2025 at 10:30 AM emanuel stiebler <emu(a)e-bbes.com> wrote: > On 2025-11-30 14:53, Peter Ekstrom via cctalk wrote: > > Very interesting thread.

Requesting advice on my restoration

by me＠scifidan.com

I want to prep the outer shell of my new tandy model 102 for paint and wish to remove the beautiful metal badgee from its recessed holder. I considered using a heat gun but fear it may effect the plastic casing around the badge. Last thing I want to do is damage the badge. Any clues?

CNC with pdp 11 minicomputers

by devin davison

It's been a while since i last wrote to the list. I have been reading up a lot on early cnc systems. While recently picking up some left over tech from a shutdown machine shop, spotted a early cnc system with some kind of minicomputer attached. Looked to have some kind of tape drive and paper tape punch. It looked like it was stored under a leaky roof, ball of rust, it looked too far gone to salvage anything useful. Sadly phone was dead at the time and i did not get pictures. Reading up on wikipedia, Data General Nova and Dec PDP 11 mini computers are mentioned as used in early cnc. Are there any surviving cnc systems, details, or software for the pdp 11? I am interested to know a bit more how the hardware was interfaced. I have pdp 11/34 systems for example, not sure if the external machine hardware is directly wired into the unibus with a/d cards, or if some kind of external hardware controller is driven by the pdp. I have not found much info on any software used for this purpose. Any accounts of how this worked or other interesting stories / info much appriciated. Thanks, Devin D'Amico

STD Bus based Little Big Board

by Doug Jackson

Hi Everybody, I am on the search for a Pulsar Electronics Little Big Board (STD Bus Based) from the mid 80's. My board has some very weird bus faults that I am trying to diagnose. Having a working one would radically simplify my life. I am located in Canberra, Australia, and am happy to pay for the board and postage from Alaska if necessary :-) Kindest regards, Doug Jackson em: doug(a)doughq.com ph: 0414 986878

Re: IBM 2315 Cartridges (Paul Koning)

by Carl Claunch

I am interested in reading these and archiving the contents. I restore IBM 1130 systems and am archiving software to be shared with enthusiasts and museums. Located in Florida so shipping would be necessary. Might need to be creative to keep the cost of shipping reasonable. The cartridges are not sealed, thus you can open them without a clean room. The plastic hardens over the decades and it is not uncommon to have the springy metal plate detach. It would be important to get the detached ones out of the cartridge otherwise they could scratch the recording surface and ruin the disk. These have eight sector marks per rotation although the IBM 1130 hardware skips every other mark to use these as a four sector disk. Carl
