How to reproduce the DEC cabinets' grey colour paint?

by P Gebhardt

Hello list, does anybody of you know colour codes or the mixture to obtain the grey paint that DEC used for their early H960 cabinet side panels as well as for their later cabinet from the 80s and 90s like the H9A10 or H9A15? Some of my cabinets have scratches and I would like to cosmetically fix this. I thought I remember some discussions about DEC paint some years ago but I couldn't find anything helpful in my archives except for discussions about colours for DEC's classic front panels. Any pointers are very much appreciated. Thanks, Pierre ----------------------------------------------------------------------------- http://www.digitalheritage.de

Old fashioned PCB layout images, red/blue

by William Sudbrink

Hi, What is the "correct" name for the style (technology?) of circuit board layout images where the top is blue, the bottom is red and overlaps are purple? Also, any silkscreen is black. I thought someone once told me that there was an automated tool (maybe in KiCad?) that would produce Gerbers from that type of image. Does anyone know of such a utility?

Oh yeah and if it is super cheap even better. Thanks! What about one of these? https://www.amazon.com/dp/B07DWLS7DP $11.38, and provides four ports. If that's not enough, you could do a bi-level multiplex arrangement; 5 of these ($56.90) would provide 16 ports. Zero power requirements, no software configuration. If it were me, I might consider buying a two-pole rotary switch with enough positions and solder one up, but for less than 12 bucks, it's hard to beat this... ~~ Mark Moulding

HP 3000 system w/ Printers, Terminals, all working, for sale on eBay (or privately...) Possible Free Delivery!

by mark＠markesystems.com

I've just listed my complete HP-3000 system on eBay here. This is an HP-3000 917LX system with: Disks: (2) 2GB drive (possibly RAID, but I'm not sure) Tape: (2) DAT (built-in and external) 16-port terminal concentrator 12-port Ethernet hub Terminals (2) HP 700/96 + one 700/92 that probably doesn't work Line-printer 300 LPM with stand, ribbons, and paper Dot-matrix printers (2) with ribbons All cables MPE/iX, ASK/ManMan, QUERY, TurboIMAGE FORTRAN Documentation (50+ pounds, including all service and upgrade records) It all works perfectly (as of two days ago). There's a possibility that I might deliver it if you're near Portland OR or the San Francisco Bay area, or off the I-5 in between; otherwise it's local pickup only (in either location). It's listed for $2600 buy-it-now, or a starting bid of $2000, but if you're really interested email with an offer and we'll see what can be worked out... ~~ Mark Moulding

Dec pdp 11 ultrix

by devin davison

Hello, Been a while since i last posted here. I have a few pdp 11/34 systems. The drives i am using are RL02 drives. Is it possible to install Ultrix on a 34? I have been testing out Ultrix in the simh emulator. I see during the install the 34 mentioned as a recognized cpu type, but later in the install the system hangs. This hang does not occur if i emulate a later cpu system like the 11/83. Not sure if ultrix can be installed due to the memory limitation, if not, rsx will be my second choice. Hoping to have some real hardware running soon! Thanks, Devin D.

Odd Unix computer Bio-Rad SRC 3200

by Douglas Taylor

I have a Bio-Rad SRC 3200, which is a workstation that operated a Bio-Rad FTS-40 FTIR spectrometer. A few years ago I got it to power on and it runs Unix variant, their product name was Idris. I have 16 floppies (dated 1992) that came with the system, but the hard disk has died. It is based on a 68030 CPU and has a floppy and SCSI disk and QIC tape drive. Is it possible to run some flavor of BSD on this hardware? What are the minimum requirements for BSD? Doug

Ethernet Transceivers....

by D. Resor

I was looking at this page on DigiBarn, https://www.digibarn.com/collections/parts/ethernet-taps/index.html and the old Ethernet transceivers. For the life of me I cannot remember what the transceivers used with the Xerox 6085 (Daybreak) looked like in 1989. There was wall to wall Xerox 8000 servers mixed in with 6085-Is at the software testing lab, in El Segundo, California, DSBU (Documenter Systems Business Unit) but that is now mostly a faded memory.

What is an "FS/2" connector?

by Grant Taylor

Hi, I just saw an unknown to me connector listed on an eBay auction and was wondering if anyone knows more about an "FS/2" connector. Link - FS/2 to IBM PC-AT P-1940-0042 CABLE 6 FOOT FREE SHIPPING - https://www.ebay.com/itm/304580270070 I assumed it was a typo / poor original copy that should have been a "PS/2". But hovering over the label on the first three pictures clearly shows "FS/2". Whats more is the kerning on the "F" is easily differentiated from the "P" elsewhere on the same label. So it seems that it's not the typo / faded label / etc. that I assumed it was before clicking on the link. So ... does anyone know what an "FS/2" connector is? -- Grant. . . . unix || die

Agenda VR3 MIPS cross-gcc

by Cameron Kaiser

There used to be a cross-compiling gcc for MIPS specifically for the VR4121 in the Agenda VR3 PDA, but it doesn't seem to be on any of the remaining sites. Anyone out there got it or, he asked hopefully, the entire SDK? Binaries OK, source better. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser(a)floodgap.com -- You can't fool me: there ain't no Sanity Clause. -- Chico Marx -------------
