Hello, I had asked this question on the tuhs discord channel, no response yet so i figured i would try here. I'm working to get my pdp 11/34 and 11/45 running. I was curious what versions of unix or bsd would work on the machines i have. I wanted to set up the systems with a bunch of dumb terminals and show them off at a local maker fair. If possible too, id like to be able to telnet in to unix or bsd.I was also curious if a ethernet interface exists for my unibus systems, or if i could SLIP/PPP serial to another machine,so i could telnet in as well as use dumb terminals. On a bit of a side question, did minix exist for the pdp11? There is mention of it on wikipedia, but ive not found much other mention of it. I read the minix book, and have used it quite a bit on the ibm pc, so i figured i would ask if a copy for the pdp 11 is out there. --Devin D.

Micropolis 1525 stuck heads

by cz＠alembic.crystel.com

Ok, so out of the basement came a Micrapolis 1325 (the old Dec RD53 disk) with what appears to be stuck heads. Rotor tries to move under power but can only take out slack. Will move backwards a bit. Is this stuck head, and what would be the best way to free it? The reason I'm asking is this disk had a SA1000 adapter mounted under it so I am pretty sure it was a PERQ disk. Which means data may be priceless. And of course it's stuck. Thoughts? CZ

Hello, Does anyone have a (set of) ROM image(s) for the VAXstation 100? It might be interesting to attempt an emulator.

R.I.P. Clive Sinclair

by cisin＠xenosoft.com

Clive Sinclair died at 81 after a long illness (probably not Covid) 'course now he is touted as being "the inventor of the pocket calculator" (as with all "FIRST"s, it leaves out a few predecessors,such as Busicom (1971, whose contract with Intel led to the 4004), Kilby's 1967 "Cal Tech" at TI, etc.) I'm not sure, but the HP35 might even have preceded the Sinclair calculator. As with all "FIRST"s, an entry can be saved by redefining the field. Sinclair's was probably the first one costing 5 pounds or less.

Burnable, patched Microvax-2000 SCSI-boot EPROM images?]

by holm＠freibergnet.de

..the compatible Device for the Labtool-48 is the Dataman-48, Software is here: https://www.dataman.com/dataman-4848lv-resources Regards, Holm ----- Forwarded message from Holm Tiffe <holm at freibergnet.de> ----- Date: Wed, 22 Sep 2021 07:45:32 +0200 From: Holm Tiffe <holm at freibergnet.de> To: Jonathan Stone <kiwi_jonathan at yahoo.com> Subject: Re: Burnable, patched Microvax-2000 SCSI-boot EPROM images? Ok..sounds good so far.. I have an Labtool-48 Programmer for example..thats an old Promer with an parallelport. Software is available for an OEM Device and I'm using that. Forgot in the moment what this was..but I can check that later. There are at least 3 Versions of the Promer that are more or less incompatible to the others, there are "upgrades", with other PCBs in there..last variant is able to do USB.. I'm owning the "plain" variant. Another from my stuff is an HiLo ALL07, and I have German made GALEP III and GALEP IV. All with Centronics Interface.. good Promers. I think it is ok to have old programmers (and old programmer-conterollers (old Laptops)) dedicated to them. I never had to program 3,3V Eproms an such things.. every time old Devices like Eproms, GALS or even TTL ROMs. 82S100 too.. I'm a german.. and sending Eproms from here seems to be the worst case to me...

If I can't figure it out by comparison to 3100 code, I'll contact Ragge and set up remote access via a BCC08, a NetBSD laptop, and serial.

"Amazon's choice" is https://www.amazon.com/dp/B082D5NQ2P. The costlier option includes 10 different sockets, and it claims support for 29xxx and 29Cxxx EPROMs, plus lots of others. > > The DEC-badged Data-IO " on eBay is tempting, but expensive, and I don't know where to find software. -- Technik Service u.

Toad1 XKL version of TOPS20 v7

by bobsmithofd＠gmail.com

I have noted that the Computer History Museum has a number of donations from XKL re Toad1. Rich Alderson might be the resident expert for this set of questions. two questions are thus prompted, and a third teased. 1. Does that XKL version run on the KLH10 emulator? 2. Is the tape CHM has been archived anywhere it might be available for download? and the teaser 3. Has anyone created an SSH Server for TOPS20? thanks bob smith

First SCSI HDD - Priam 806 8-inch?

by tom94022＠comcast.net

It turns out the Priam 806 8-inch SCSI HDD circa 1984 is likely the first HDD to have a native SCSI interface. It shipped a few months before the Xebec Owl which is likely second. AFAIK all earlier units had a bridge controller to a more conventional interface. If anyone has any different info as to dates and models I would appreciate it. Does anyone know where a Priam 806 might be, or have any documentation? The former probably belongs in a museum and the latter on Bitsavers. I will help facilitate either.

Hello all, I have a Data General Model 5220 MT terminal I picked up recently. Sadly, no keyboard.

Any help is appreciated.. in fact any information about this device is appreciated.. I?m finding nothing about this terminal on the interwebs! Thanks!
