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?

Is it half inch tape, one inch or quarter inch? Any idea how many tracks? Someone said it was 61-63, well half inch drives then had ten tracks, later seven tracks and later still nine tracks. Some analogue recorders had even more tracks. Roger Holmes Owner of a dozen Ampex TM4 ten track drives.

Anyone interested in a Coleco Adam?

by alanp＠snowmoose.com

A friend of mine has a Coleco Adam (and bits to go with the system) that he wants to get rid. I do not yet have the complete list of what he has. Anyone here interested in it? It is located in Shelton, WA. It sounded like it was free, but I need to confirm that. alan

Coleco Adam system available

Coleco ADAM! Now there's a system seldom heard these days! I'm an old Adamite at heart. There may be someone on Coleco Adam lists that may be interested. Murray-- "Computing forever!"

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. It used the same switch type keyboard. - Jerry Jerry Wright g-wright at att.net --------Reply: I've got a few boxes full of keyboards & parts; any chance of a picture off-list? mike
