NeXTStation Color monitor cable pinout needed

by ian_primus＠yahoo.com

Thanks to your help, I now know what I need - I need the three headed cable with two 13W3 connectors and one DB-19. ( this thing - http://www.obsoletecomputermuseum.org/nextcolor/monitor_cable.jpg ) I have scoured the internet looking for the pinout of this cable, but to no avail. I did find some information about the monochrome slabs, but it doesn't help me very much. There doesn't seem to be much out there about the color NeXTStations at all. Anyway, if anyone has the pinout of that monitor cable, it would be much appreciated. It shouldn't be too hard to add the extra connector to the old Sun monitor cable I already have. All the pins on the Sun cable do go straight through, and there are wires for all of them, I checked with a multimeter. Thanks! Ian Primus ian_primus(a)yahoo.com

PDP-8 front panel switches needed

In the interests of keeping viable machines still functioning, and given that this is for a non-functional museum display, it might be worth looking into actually making something - painted wood, vacuum-formed plastic, whatever. Just a thought. I'm not a DEC person (don't have the space!) and these switches might be common as muck for all I know. But I'd hate to think parts were being used on a static display that could be used to keep hardware running elsewhere... cheers Jules Everything you'll ever need on one web page >from News and Sport to Email and Music Charts http://uk.my.yahoo.com

vaxstation 3000?

by acme＠ao.net

Okay, I'll bite. Questions (from a non-DEC mperson): Where is it? Where can I find information about the VS3000? Google pointed me to tons of sites regarding the 3100, 2000, 4000, etc., but nothing specific to the 3000. Why? Is the 3000 a dog? To the classiccmp DEC-heads: is the 3000 a good starting point for someone who's curious about VAXen? If not, why not, and what would be a better place to begin? TIA -- Glen Goodwin Orlando, FL USA > Anybody have any interest in a VaxStation 3000? > Looks clean, no monitor or kbd.

Berg Connectors

by chd_1＠nktelco.net

Is there a replacement for the Berg connectors? I am talking about the 100mil spacing, dual inline connectors that had individually insertable, crimp contacts. The AMP MT connectors look like a replacement. Does anybody have experience with this? I am working on an DEC RX01/RX02 emulator for my pdp-8/e and want to run a cable about 20ft. I was thinking about using 4 runs of cat5 twisted cable and the individually contacts would be quite convenient. -chuck

Getting Started with VAXen (was Re: vaxstation 3000)

by classiccmp＠crash.com

> To the classiccmp DEC-heads: is the 3000 a good starting point > for someone who's curious about VAXen? If not, why not, and > what would be a better place to begin? If you want to get started with VAXen, any flavor of VAXstation 3100 would be a great place to start. A basic VS3100 (aka model 30) would be an adequate, very cheap way to start. They'll do everything you'd need to begin learning about the VAX and VMS, Ultrix, or *BSD. These early models are limited in terms of expansion and speed by current standards, however, and if you have the money or opportunity you might want to look for something faster like a VS3100 m76, or any VS4000. To learn more about the different VAX models, I'd take a look at the NetBSD/VAX page http://www.netbsd.org/Ports/vax and look into the different model descriptions. To get licenses and media for running VMS, go to the DECUS/Encompass OpenVMS Hobbyist Pages at http://www.montagar.com/hobbyist/index.html You'll have to join Encompass, but that's free. And you'll need the serial number from your VAX/Alpha. If you check the archives for this mailing list, or hit Google Groups archives for comp.sys.dec and comp.os.vms, you'll find all kinds of info and links to web sites. Good luck, and have fun! --Steve.

Question on chip date code

by vcf＠siconic.com

I am looking at a chip that is causing me confusing with regards to its actual date code. The chip is labeled thusly: (logo) /718 DM74157N 9322 (logo) looks something like this: /\/ /\/ ...which probably makes it National Semiconductor. My first instinct is to guess that its date code is 9322. However, it does not fit within the context of the rest of the board, which is 1976. They are definitely not original, as the board calls for a 74257 but the 74157 has been put in its place with the addition of a capacitor across +5 and ground. Is it possible that the date code is actually "/718", and what I am seeing as a slash is actually what remains of a '7' that wasn't printed correctly? -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

Mac Printers (Cambridge, UK)

by julesrichardsonuk＠yahoo.co.uk

OK, I haven't decided what I'm doing yet with the various Apple machines I got the other week, but I know the printers are just getting in the way, so if anyone wants the following just give me a shout: Apple Stylewriter II + manual Apple Colour Stylewriter 2500 - no PSU, needs 13.5V HP Deskwriter 660C + PSU + driver disks (ok this one doesn't hit the ten year mark :) I had the same printer for the PC which failed a while back, and I kept the centronics interface board from it so you're welcome to that too. I may also have the manuals for the PC version still, which might be useful. I've only got the one data cable, currently plugged into the colour stylewriter; I expect it works with all three printers though. I have no idea what of the above works - all the systems that came in the same haul worked fine though so I expect they were just dumped as surplus.

PDP-8 front panel switches needed

Does anyone know of a source for (or have) enough PDP-8 (the original "straight") front panel switches to fill in a front panel? I am working on a replica of the PDP-8 (non-functional) for a museum exhibit, and need to find either a source for switches or some that look close enough. If you have some you wouldn't mind parting with, please contact me with your asking price. If you know of a source, please pass it on.

NeXTStation Color DSP cable pinout

by ian_primus＠yahoo.com

I recently accquired a NeXTStation Color, complete with color monitor and DSP box. Unfortunately, I don't have the cable to go from the NeXTStation to the DSP box, and therefore, I can't use the computer because the keyboard also connects to the DSP box. Does anyone have the pinout for this cable? Also, how does everything connect? I have seen various info on the internet that conflicts. I am assuming by looking at it that the monitor port is just a monitor port, and connects to the monitor through a standard 13W3 cable (came with the computer, but it Sun branded). Then the sound box would connect to the computer through the DB-15 on the back of the computer labelled "DSP" and to the DB-19 port on the sound box. Then the keyboard plugs into the sound box. But >from searching the internet, I have found things such as this http://www.obsoletecomputermuseum.org/nextcolor/monitor_cable.jpg that show a three headed cable that would connect the monitor to the computer, and to the back of the sound box. But then what would the DSP port be used for? And how would the computer get the signals from the keyboard? I'm new to NeXT hardware, so any help would be greatly appreciated. Thanks!

VHS Tapes as storage.

Hi, I seem to remember reading in popular electronics, about software that would let you use a vcr to backup your computer. I think it was about 10 years ago. Does anyone remember or know anything about this. My searches on google have turned up nothing. Thanks for any help you can provide! Andrew Strouse

I'm fairly sure it's not an 11/05-S, though I could obviously be wrong. I don't have the machine in front of me right now. Looking at the machine you have, the form-factor is very different (that, of course is not conclusive).

11/44 is alive :)

by jwest＠classiccmp.org

Thanks to all who helped! I checked out my backplane (NOW I see why the 44's always tilt up in the rack, so you can frequently get to the backplane wiring) and sure enough, missing NPR jumpers. I wire wrapped them back in (laughing at just how long ago it was since I had to use a wirewrap tool) and now - voila. The 44 comes up just fine, passing T, T/E, and T/A tests anyways. I can also deposit and examine a random memory location or two, probably a good sign. Now I just have to find out why it doesn't seem to think I have a TU58 attached...then get some RL02's up... Another question - I was perusing the net for what OS's I can run on the 44. I already have RT11 with TSX+ up on another machine, so on this one I was looking for something different. Being as my bent is multiuser basic machines (like HP2000 TSB), I was piqued by some references to EduSystem25 I think it's called. I got the impression it USED to be Poly BASIC, but that software was later acquired by DEC and turned into the EduSystem25. There was a link saying where EduSystem25 can be found, but alas, the link is dead. Does anyone know where manuals and media might be found for EduSystem25? Thanks! Jay West
