Hi All, I've decided to get rid of my Dec PDP 11/04 and I thought I would offer it up on the list first before hitting eBay (so No, it's not free). Here's a couple of pics: http://homepage.mac.com/irisworld/vintage/1104_001.jpg http://homepage.mac.com/irisworld/vintage/1104_002.jpg Here's the list of boards: m7859 m7647 m7847 m7856 sms fd 1100i You can pick up in Port Huron, MI. 48060 or I can ship it (naturally you pay for packing materials and shipping cost) or you can have your favorite craters and freighters come and get it. Please send all offers off list. Cash via paypal is the best but I would be willing to trade for a Data General Desktop Generation system or an Aviion. Thanks Rob ps. Yes I have the top cover for it.

Pasadena rescue update

by dgriffi＠cs.csubak.edu

Because of the interest in this collection, I have decided to take on the Pasadena rescue into my inventory and auction it off. I've been told that the family of the deceased is not well-off. As such, I cannot in good faith broker a simple giveaway when the items could be sold to pay expenses. Here's what I expect to pick up: 1 Altair with a homebrewed front panel 1 Altair (regular 8800) 2 IMSAI 8080 machines 1 external 8-inch floppy drive 1 ADM3 or ADM3a terminal 3 or more IBM PCjrs, some with sidecars. Many components are unopened. I'll know more about these machines (like what's in the S100 chassis, if there are PCjr monitors) when I take custody of them. Due to my own storage problems[1], I will not be picking up any documentation that's not directly related to the above items. Once I have the machines, I will dispose of them within two weeks. My primary venue is Ebay. If you're interested in these items and don't want to deal with Ebay for whatever reason, please email me and we'll figure something out. [1] From my last two hauls, I was obligated to take a great deal of documentation that I cannot possibly catalog or distribute myself. I'm expecting one particular list member to come down to get some and I expect there to be a lot left over. The docs are mostly S100 in nature. -- David Griffith dgriffi at cs.csubak.edu

Backing up VAX/VMS?

by dave06a＠dunfield.com

Hi Guys, Recently acquired some VAXen - I have a soft spot in my heart for VAX/VMS as I worked professionally as a user on a VAX/VMS system for quite some years, however I have little to no experience from a system administration standpoint. What I have: VAXstation 3100, currently running NETBSD VAXserver 3100 - Installed hobby version of OPENvms on it. VAXstation 4000 VLC - Has a full VMS 5.5 installed on it. Datability VCP300 16-port LAT terminal server (The VLC appears to load LAT networking when it boots, but I haven't looked into it further yet) My immediate concern is that I'd like to make a full backup of the VMS 5.5 on the VLC, and also attempt restoring it to another drive. Not quite sure what the best way to go about this is, and I want to make sure I *DON'T* cause any damage to it in the process, so I'm looking for someone experienced in VMS who can give be a bit of advice/guidance. I've got some documentation that I've dug up on the web including a VMS administrators guide, and I also have the full VMS 4.0 documentation set (about 3-feet of paper!). I've seen reference to booting stand-along BACKUP - I do have the OPENvms install CD which appears to boot to a configuration which can do stand-alone BACKUP (at least it can restore from a backup image on the CD). Possible backup media that I have available: - A pair of Exabyte HH-CTS 8mm DAT tape drives - A SONY SDT-5010 4mm DAT tape drive - SCSI ZIP Drive - Another SCSI hard drive Are any of these feasable as a backup medium for VAX/VMS? (All three of these machines have SCSI ports) If so, any pointers as to how to configure the drives/media to be recognized and accessable to the stand-alone backup, and info on how to perform such a backup would be most appreciated. I'll probably pull the original drive and install OPENvms to another drive for a "test run" before I try and backup the original system. Related topic: Keyboard/Mouse emulator? So far most of what I've been doing has been via a serial console, however both the 4000 VLC and the VAXstation 3100 support keyboard and mouse - The VLC has a VGA video connector, and I've found a couple of LCD monitors supporting sync-on-green which work on it. I've also scrounged up an LK-201 keyboard which works, and I'm working on acquiring a DEC mouse ... I did figure out how to activate "dead rodent mode" which lets me do mouse movements through the keyboard, and DEC windows does come up and run! I found details of the keyboard and mouse protocol in the back of a Microvax manual, and have been toying with the idea of building a small embedded controller to take a PC (PS2) keyboard and mouse, and emulate the DEC equivalents to the VAX - would anyone else be interested in this?

Luckily it seems the video converter board I want to use has separate TTL-level horizontal & vertical syncs, just like VGA. I still need to determine the video signal amplitude, but it's looking like I'll just be able to use a resistor to connect it to the green line of the monitor. My monitor has 5 BNC inputs and can be set to high-Z, but I'll be running it through a KVM switch which has normal VGA connectors. The KVM probably has on-board termination. The amplitude probably isn't sufficient to drive 75-ohm red, green and blue lines without buffering/amplification. Horizontal sync frequency will be around either 31kHz or 54kHz depending on the mode (pixel clock 49.5MHz or 72MHz), so most modern (CRT) monitors should be able to handle that. Interestingly, looking at the board circuitry there seems to be a facility to provide your own pixel clock, so the horizontal & vertical frequencies could be adjusted if necessary. (Or maybe that was only used for factory testing.) -- Mark

Keybard repair help. Older terminals

by dm561＠torfree.net

-------------Original Message: Date: Sun, 13 Jan 2008 21:07:00 +0000 From: g-wright at att.net Subject: Keybard repair help. Older terminals I seem to have my share of Terminals that have bad keyboard parts. 3 that I'm working now have the same type of Keyboard. These are Hazeltine 1500 and ADM 3As. These have an molded base with fingers that stick up and a second square piece that slide into the base and makes and breaks the finger contact. It also has a square opening in the top for the key cap. So when someone drops a heavy object on the the key board this intermediate piece cracks in the corners and binds in the base. What I would like to find is a doner type of system that does not have any value so I can rob the middle piece.. (typewiter) ??? Tandy (Archer) sold a Alpha-Numrtic keyboard that said it was made for the TI 99/4 computer.

PET power supply questions

by ethan.dicks＠usap.gov

Hi, all, I've been collecting various classic bits to work on over the winter, including a pre-CTRC 32K PET board (2001-N/3032) and a Static PET board. I don't have any cases or accessories, but I do have a C2N232, a single bare keyboard, and a C=Key converter enroute. For video, I was planning on trying that ancient XOR circuit to make composite video >from sync and video, and feed that to an old Panasonic mono CRT I saved >from scrap. What I'm lacking at this point is a power supply. Obviously, I'm unlikely to find a suitable mains transformer, so I was going to cobble up some form of switcher that puts out enough of the right voltages to make this all work. Poring over the schematics for the 2001-N board on zimmers.net (e.g. 320349-9.gif), I'm guessing that the onboard regulator circuit is pumping out +5VDC at over 5A, +12VDC at a couple of amps, and a miniscule amount of -5VDC. I'm not running a real tape drive, so I'm not as worried about the +9VDC unreg. Does anyone have any reasonable estimates or real-world measurements for the current draw on the various supply lines? Has anyone out there ever gotten a PET to run from externally regulated DC?

Free PowerMac in SE England

by lproven＠gmail.com

Would anyone like a free PowerPC Macintosh? An acquaintance of mine has one he wants to get rid of. It's a PowerMac 7200/90. Spec unknown, I'm afraid, but it'll be running MacOS 8 or 9 or so. I believe these machines can be coaxed into running OS X up to 10.4 with XPostFacto, although you'll need to stick to at most 10.1 or 10.2 unless you put a G3 upgrade in it. Either way it will need more RAM and hard disk space to run OS X. It's just outside Brighton. The owner is James Fryer, jim at cix dot co dot uk. -- Liam Proven ?

Why not write out a BACKUP tape with standalone BACKUP at the front so you can do a restore install? Only read about it being done on TKxx/TZxx drives, but it would be worth looking into, as it is the "official" DEC way to build a restorable backup (and is how they shipped the VMS tape distros) (haven't read too much about it because I don't have any CompacTape media right now).
