Installing OpenVMS Software

by cool1＠thecoolbears.org

I have a VAX that I like to play around with. I don't know VMS very well, and it's fun to learn new (well ok, maybe VMS is old now) things. There's an application that I would like to compile, but it depends on bison. I'm trying to compile bison, but that process seems to depend on MMS. I'm assuming that MMS works like "make makefile" and you do "mms whatever.mms" to make the app. MMS doesn't seem to be installed, so I registered and loaded the license. The SHOW LICENSE command says that the license is there. Now I need to install the application. I have the Montagar CD mounted and I can browse it's tree structure, but I can't find the kit that includes MMS. I thought maybe the C language kit and I tried: @SYS$UPDATE:VMSINSTAL CC064 DUA2:[CC064.KIT] ...which reinstalled C, but no joy on MMS. Any suggestions?

seeking ExperLisp by Expertelligence for Macintosh

by nigel.d.williams＠gmail.com

I used this in the 1980s and would like to get a replacement copy for the one I lost - thanks. Last year on eBay someone purchased a large collection of Macintosh diskettes, one of which was an ExperLisp diskette, so if that person is a cctalk-er I would appreciate a reply. It was released for the Mac 512K and later Macintosh.

TTI 8510 Manual and/or switch settings...

by lbickley＠bickleywest.com

I recently acquired a clean TTI (Transitional Technology) 8510 8mm SCSI tape drive. I've searched Google extensively - but have found no manual or even a switch settings guide. It emulates an Exabyte EXB-8200/EXB-8500, a DEC TK50Z, an IBM 2.3 GB or the native TTI 8510 (from Google). It has twelve dip switches, three of which I've found to be the SCSI address - the others are a mystery. Does anyone have a manual or guide to the switch settings for this tape drive?

Interesting email addresses of old...

by mark＠wickensonline.co.uk

I was just trawling through some of my file archives and found my old email address when at University: mwickens at vax2.luton.ac.uk - from 1993 to 1996 At the time I wasn't really into VAXen, but subsequently have wondered about the VAX that handled my emails during that time. In the last year a new Alpha system came online, and new email accounts were set up on that box. Anyone had interested email addresses in the past, or an email address which represented a nostalgic time in their life. The fluidity of email addresses interests me academically and professionally - I work on systems which traditionally have involved postal communication, but are moving over to email based communication. This represents a challenge due to the fluidity of email addresses over the course of the years. Regards, Mark.

New rsync mirroring at trailing-edge.com

by shoppa＠trailing-edge.com

Last weekend I promised to enable rsync access to the archives (and mirrors) here. I've set up the following rsync (no password required) archive sets here: ftp : Public rsync access to ftp://ftp.trailing-edge.com/ area pdp-10-tape-images : public rsync access to the PDP-10 tape images, i.e. http://pdp-10.trailing-edge.com/ bitsavers-mirror : public rsync access to my local bitsavers mirror, i.e. http://bitsavers.trailing-edge.com/ Suggested rsync commands would be, for example: mkdir ./pdp-10-tape-images rsync -rlptu -v www.trailing-edge.com::pdp-10-tape-images ./pdp-10-tape-images mkdir ./ftp.trailing-edge.com rsync -rlptu -v www.trailing-edge.com::ftp ./ftp.trailing-edge.com mkdir ./bitsavers-mirror rsync -rlptu -v www.trailing-edge.com::bitsavers-mirror ./bitsavers-mirror Realistically the pdp-10-tape-images and ftp sites don't change often, butm my bitsavers mirror is kept up to date. I like to think my outgoing bandwidth (20 Mbit) is pretty much infinite, this looks like a good way to find out :-) ftp racks up to 3.5 Gbytes. PDP-10 tapes racks up to 2.2 Gbytes. And bitsavers-mirror racks up to 126 Gbytes. Tim.

I guess most of us on this list appreciate old and original copies of things. I have a small collection of old doc (although most of it is inaccessible to me at the moment) and record albums, photo albums etc. Things just seem to become unmanageable as the years go on and what was easy to find today can quickly disappear tomorrow.

Soldering stations - OKi-Metcal, Pace or something else?

Somebody I know had a Volvo V70 that just refused to start one morning. Nothing obviously wrong, it just would not start. It had to be towed to a Volvo dealer. IIRC the problem turned out to be that two of the car's computers decided they didn't want to talk to each other. A software upgrade fixed the problem. It may even have been the case that none of the computers had to do with engine management. The owner of the car is very clueful about hardware, software and cars, but it would still have been a major undertaking for him to even find the problem, let alone obtain the software upgrades. > And I realyl don't understnad why service information is not supplied > with (or at least available for) devices that are almost cetainly > goign > to be owned and used by people with eelectroncis knowledge -- > soldering > stations , mutlimeters, 'scopes, etc. I've still not bougth a new DMM > after my Fluke failed last year because I've yet to find a > manuafactuer > who will supply a service manual. > Because they want you to either buy a new unit, or send the unit to one of their own facilities to be repaired? In case of car manufacturers I believe a significant portion of their profits comes from spare parts and service. Do you have a mobile phone? Modern ones seem to be designed to break down slowly after about 18 months, they are full of custom parts, and the people who repair them do their best to drive you mad. My work phone is (hopefully) being repaired right now. It is 17 months old, the display went permanently blank around August 6th, and the repair people have most likely not started working on it yet. I shall probably have to wait another 2 weeks for it. /Jonas

More DEC Bad luck.

by bdwheele＠indiana.edu

I'm convinced that my house was built over an Indian burial ground. Or it was owned by someone heavily invested in everything but DEC... I powered up my AlphaServer 1000A last night and it looks like it has problems too. It powers up and the drives & fans spin up. The lcd showed 'ec.' only once, every other time it is blank. Nothing out of serial port 1 and the onboard VGA never initializes. I tried setting the 'failsafe boot' jumper and I put a blank floppy in the drive just to see if it would try to read the floppy and it didn't even try :( Any ideas at all? So now it looks like both of my alphas are shot (the PWS500au never initializes video, does anything with serial, and turns off all diag lights) and my DECStation 5000/120 has a bad power supply. On the plus side, all of my terminals still work and both of my vaxes (MicroVAX 3100/90 and VAXStation 4000/90) boot to VMS without problems. It brings me to a question: are the alpha systems inherently fragile? The dead DECStation is an obvious hardware issue due to (probably) a leaked capacitor which is understandable due to its age, but the Alphas are just hosed in a software kind of way. Brian

WTD: 0.156in 2x10 or 1x10 edge connector for Motorola/Displaytek M1000-355 CRT

by classiccmp＠philpem.me.uk

Hi guys, I just picked up a Motorola M1000-355 CRT monitor (5in diagonal open-frame industrial "thing", circa Jan 1987 so almost as old as I am!) at the hamfest today.. Problem is, I don't have a suitable mating connector for the card edge connector... It's a 10-pin single-row card edge connector, with a 0.156in pin pitch, although I suspect a dual-row (20 pins total, 10x2 layout) would work fine too. These are listed as "US stock only" or "Discontinued, obsolete" by every supplier I've tried... Does anyone have one squirrelled away in a box somewhere which I could buy or have (he says with a cheeky grin) ? Or possibly a lead on a source for one or two of these, ideally with keypins (but the latter isn't essential)? I'd also rather like a copy of the datasheet for the monitor module if anyone has it... I have a pinout (it's the standard 10pin pinout as posted by Tony Duell quite a while ago -- IIRC either the Kaypro or Osborne monitor uses the same pinout) and a sneaking suspicion that it's CGA-spec, but no hard proof. I do know that it pulls 12V DC at about an amp -- the first value is printed on the PCB, the second was provided by the meter on my bench supply!

Opening up an RD54 Disk

by robert.jarratt＠ntlworld.com

I want to get the lid off one of my RD54s. Having unscrewed all the 12 torx screws, the lid still seems to be held down by something. I have probed around for any screws under the label but only found one curious red plastic thing. Is there a trick to this or is it going to be just the rubber gasket that is holding it down? Thanks Rob

Soldering stations - OKi-Metcal, Pace or something else?

by classiccmp＠philpem.me.uk

Hi guys, Well, we've got a thread on desoldering kit, so I'm going to start one on soldering stations... :) It seems my love-hate relationship with my Antex 660TC soldering station has finally become one of almost pure hate. I sat down to assemble a couple of DiscFerret boards tonight, and after about 40 minutes the handle of the iron was too hot to hold. Tried again with the other iron, same story. If I hold it any further back, then the whole thing is completely out of balance... So I figure it's time for a change. Hopefully to something which won't try and roast my fingers. I've narrowed my choices down to two manufacturers -- OKi-Metcal and Pace. This is basically because they're the only two "professional" brands Farnell carry (I did look at some of the Weller soldering stations but they don't look much better than the Antex). I'm looking for something that'll suit SMD work -- ideally one which has "mini-wave" soldering iron bits (aka "hoof" bits) easily available, and is designed for lead-free work. I do run an SnPb line as well, though I'm slowly phasing it out (once I run out of 60-40 solder, which might take a while...!) At the moment the front-runners are: - Pace WJS100 (with TD-100 and Instant Set-Back aka auto-standby). Not overly keen on this one, seems overpriced when compared to other Pace kit (especially when you consider that the WJS only works with certain soldering bits and one type of handpiece) - Pace ST50 + TD100. Seems about the same as the WJS100, but will run the tweezer handpiece and a wider variety of bits. Catch is, I'd have to special-order this from Pace UK if I wanted the ISB option (Farnell don't stock the ISB "cubby" / iron stand). - Metcal MFR-1110. Cheaper than the Pace (or so it would seem), cheaper tips. Also seems to have "auto standby" as standard. What concerns me is that it seems to run at a fixed temperature, though OKi/Metcal claim that SmartHeat makes this a non-issue... I'm not convinced... Has anyone used any of the above, or anything similar? Are there any other brands (or other soldering stations from the above manufacturers) that I should look at? Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
