Stag PPZ EPROM programmer

by coredump＠gifford.co.uk

I have a fine old Stag PPZ modular EPROM programmer: http://www.gifford.co.uk/~coredump/inst.htm#PPZ It takes plug-in EPROM (model Zm2000) and PAL (Zm2200) modules, called Z-modules by Stag. I've recently acquired a new module, Zm3000, which looks like a more recent EPROM module. The chips in the Zm3000 are date coded in 1993, whereas the Zm2000 is nearer 1988. The PPZ main unit contains a 6809 CPU and a small CRT display. Does anyone know anything about this system? What about other Z-module types? In particular, should the Zm3000 work with the PPZ, because I currently get an error message "Incorrect Mainframe"? Thanks in advance for any clues!

I find propan-2-ol (isporpanol) woeks well for this. Interesting, propanol is an alcohol and shouldn't be very good at dissolving grease, in theory.

Lisa Test 3.0?

by snhirsch＠gmail.com

Is List Test 3.0 supposed to work on an unmodified Lisa 2? I'm not quite sure what's going on. It starts to load and I can watch the head stepping around. Then after about 45 seconds it just stops with an hourglass on the screen. Won't respond to keyboard, mouse or the on/off pushbutton! Any sage advice from the Lisa owners on the list will be appreciated. Steve --

The number of transistors that exploded while I was building my stereo in the 70s was amazing :-) I even managed to short out a 2N3055, but I had to drop a test lead connected to its collector on to a 220V terminal on the mains transformer to succeed :-) OTOH, that also caused a BFR39 or something to send half its case flying about 10m across the room... /Jonas

It won't keep things from pinging off to somewhere where only the cat will find them, but it catches things like small screws and ball-bearings that fall out. I like to use old plastic 35mm film containers to keep small items in, one container for each subsystem/part/whatever, keeps related parts together so you don't end up with 55 nearly identical screws that you can't remember where they went. Taking pictures as you go along with a simple digital camera also helps if you do not have a service manual. /Jonas

However there is always a flood of responses strongly advising against it in no uncertain terms. Many precision mechanisms are better off unlubricated, e.g. shutters. Something else to watch out for is keeping anything silicone-based away from a camera. The silicone adsorbs to glass etc at a molecular level and is absolutely impossible to remove. I expect that doesn't apply to computers though. /Jonas

by silvercreekvalley＠yahoo.com

I have a DEC commercial cabinet available for free, together with two RL02 drives (with rack rails), a UNIBUS M7762 (RL02 driver card), and some cables. I also have a number of disk packs. The RL02 drives were working when decomissioned, and fit the DEC cab with space for a CPU unit if you have one. Items are collection only from West Yorkshire (UK). I'm not splitting the items - so its everything in one collection please. All items 'as is' I cant guarantee anything works, or if its complete. email me if interested.

Anyone have documentation for a Finlux ELM 640.350-M1 display?

by ethan.dicks＠gmail.com

Hi, All, Digging through some boxes from the attic, I rediscovered a hamfest find from some time ago - a Finlux ELM 640.350-M1 electroluminescent display. It has a couple of toggle switches and a pair of covered 8-position DIP switches, and based on the DE9M input connector and the implied resolution from the model number, I have every expectation it's an EGA-compatible display. The two toggle switches are merely marked "Mode 1" and "Mode 2", but at least the settings on the DIP switches are documented on the back of the case as follows: DS1 8 LOW HIGH INTENSITY 7 NOT USED 6 NOT USED 5 MSB \ 4 - + HORIZONTAL SHIFT 3 LSB / 2 COARSE \ 1 FINE / PHASE DS2 8 NOT USED 7 R' G' B' \ 6 B + VIDEO LSB 5 G + 4 R / 3 B \ 2 G + VIDEO MSB 1 R / I have to admit that I sort of missed the PC EGA experience (I went right from mono to VGA), so I'm not sure I fully understand the multiplicity of options this device provides. I've googled for the model number, but the closest appearance I've found appears to be a laundry list of for-sale items from 2001. My knowledge of Finnish doesn't extend far enough to fully interpret those hits, but Google Translate does a fair enough job. Anyone happen to have Finlux documentation or at least recognize the meaning behind the DIP switches? The good news is that it's a 90-240VAC input device with a standard "figure 8" plug - easy to power up, even in the States. I'm wondering what I'll drive it with, even to test it. Thanks for any hints, tips, or hard info, -ethan

taxonomy of computer assemblages

by legalize＠xmission.com

I'm prototyping my cataloging system for the Computer Graphics History Museum with CollectiveAccess. So far, so good. I've come across the need to extend one of their standard metadata profiles with data specific to my specific domain. This is a common situation. The kind folks at the Living Computer Museum recommended that I have a way of describing the various parts within a computer system: - systems assembled from racks - racks assembled from boards and hardware - boards assembled from chips - etc. However, I don't need to get bogged down into the details of each system with my metadata. I was thinking of trying to keep it simple and create a taxonomy consisting only of two categories: assembly and part. Assemblies are containers for parts and other assemblies. So, my 4-rack Onyx2 Reality Monster might be broken down into something like this: Id Assembly Name Contains Assembly Contains Part 1 System 2, 3, 4, 5 2 Rack 6, 7 3 Rack 4 Rack 5 Rack 6 CPU Rack Module 8, 9, 10, 11 7 Graphics Rack Module 12, 13, 14, 15 8 CPU Board 1, 2 9 CPU Board 10 CPU Board 11 CPU Board 12 Graphics Board 13 Graphics Board 14 Graphics Board 15 Graphics Board Id Part Name 1 CPU Module 2 CPU Module >From this simple example, I think you get the idea even if I haven't filled out a complete transitive closure of all the parts in this system. Ultimately, the goal is to be able to track the provenance of any particular part or assembly is it is moved and/or combined with other hardware in the collection in order to obtain working systems. This shouldn't be too hard with the current collection as I've hardly done anything to the systems in the collection in terms of modifications. However, as time progresses, this information will become more important. My question for the list is: do you think this simple taxonomy of recursive assemblies and parts is sufficient? I'd rather not create metadata for the sake of creating metadata in my catalog profile. It seems to me that the amount of maintenance work in a catalog is directly proportional to the amount of stuff you're trying to capture in the catalog. Your thoughts or comments are appreciated. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

VAX 7810, VAX 3620 and VAX 3610 available in Detroit

by scott.m.18＠atsgate.com

Hey, Has anyone noticed these big VAXen available in Detroit? http://detroit.craigslist.org/wyn/sys/2257545671.html They look to be on raised floor (where I am guessing they have been for the last 20+ years). I would also guess this is one of those cases where they would accept $100 from anyone who could quietly and efficiently remove the machines with minor distruption to the other activities in the datacenter. I am over 800 miles away, so not a possibility for me. -Scott

Data recovery on 8" System/36 diskettes

by ceby2＠csc.com

All -- Wondered if I could pick your collective brains. I'm helping a museum to recover data and software off 8" System/36 diskettes. The first batch is a DFU dataset. I've also got all the reference material I need on DFU and system utilities. But as I don't have PC Support/36 program media, I'm going to have to do this from a PC running an 8" driver rather than natively. To that end I've gathered up references to the IBM 2D disk format and a workstation where we're setting up a Catweasel controller and Shugart 8" drive. I'm aware of a number of utilities for forensics and disk control. Has anyone done this particular combination before? developed scripts? made cwfloppy modules for decoding the format? Any suggestions and guidance would be welcome. I'd also love to find a copy of PC Support/36 so that theoretically we could natively copy the files using 5250 workstation emulation. There is a 5362 system available to rebuild, and I have the SSP media to do the job. I also have an IBM P70 with a 5250 emulator card and software which could be used as the PC workstation, but I'm not aware of a source for this particular application media.

I wrote a page on dealing with batteries for Pinballs and Jukeboxes, but the info applies to anything that is battery powered. http://flippers.com/battery.html If the battery was Ni-Cad, then the stuff that leaked out was an alkalye (base) and should be neutralized with a mild acid (white vinegar & h20 50/50) then rinsed and dried thoroughly. You really want to deal with this sooner, rather than later...

Hi, Im emailing you to see if you are interested in a load of vintage Digital Equipment Corporation computers etc. My dad has now passed away, but he was a DEC engineer for 20+years. He amassesd a whole load of DEC computers bits when he retired. We are now clearing out the garage but are not sure what to do with all this computer stuff, and just thought we'd see if anyone wants any of it before throwing it out. Here is a brief list of whats in the garage.

free 3600 lisp machine, two 14" disks, spare boards

by brad＠heeltoe.com

I'm slightly downsizing my office space and need to get rid of my 3600. It's free for the taking. I am in Arlington Massachusetts (USA). This is a Symbolics 3600 lisp machine. The original 3600 design. Huge circuit boards. 36 bit memory. A gigantic fan. Cool red LED nano-fep. One of the coolest microcoded machines I've ever seen. And it runs off 110VAC. It's very heavy. The CPU cabinet is about the size of a large refrigerator. The two 14" disks are mounted in a DEC 1/2 height rack with no sides. The SMD disks have 14" platters and clear plastic tops. It used to work fine but I have turned it on in a few years. I have a full set of spare boards. I think I even have a color board and paddle. I think it has Genera 7.2 on it, but I'm not sure. It booted fine last time I turned it on. To me it is a thing of beauty, but I'm just not table to store it anymore and I have a 3640 and XL1200 which are much easier to care for (and much easier to move :-) Anyone want a piece of history? If so show up with a truck and at least 2 hefty guys and it's yours. Both cabinets are on wheels. Batteries not included. -brad Brad Parker Heeltoe Consulting 781-483-3101 http://www.heeltoe.com

Advice on Lisa 2 restoration

by snhirsch＠gmail.com

Hi, I have two Lisa 2s in my possession that both exhibit serious corrision >from battery leakage. One is simply bad, the other is about the worst such situation I've ever laid eyes on. I was able to remove the battery packs to halt the degradation, but before I make a bad situation worse I thought I'd ask for some advice on how to proceed. I'm also trying to work out what the units might be worth. The deal with the seller is that I'm free to evaluate their condition and attempt to get one working unit out of the two. Assuming a nominally functional Lisa 2 with functional 10MB ProFile and fair cosmetic condition, what do folks think is a fair price for that unit (the owner wants whatever is left back, functioning or not)? Prices on eBay are really all over the map, so that's not of much help. Steve --

RT-11 / RX-01 issues ... "almost" boots ...

by mcsele＠niagaracollege.ca

I am restoring a PDP-11/34 and am currently adding an RX-01 drive to it in order to boot RT-11. I have already located a copy of RT-11 on an LSI-11 system and have made a bootable RX-01 floppy (an M7946 was installed on the LSI-11 to do this). This disk was tested on the LSI-11 system by asserting BHALT, entering a bootstrap via ODT, and booting from the disk (which was, at the time, the only device): it boots properly and runs RT-11 version 5.04SJ as expected. An M7846 RX-11 controller was installed in SPC slot 9 of the 11/34, the bootstrap loaded at 1000 via the front panel (and verified), and a boot attempted. When STARTed at 1000, the RUN light comes on, the RX-01 head engages (as evident from the solenoid), and you can hear the heads advancing a track or two then it stops: the "SR DISP" led and the RUN led go out, and the display reads "005134". Examining the bootstrap area (1000) shows the bootstrap was replaced by data. Does anyone know what the "005134" code means? I search through RT-11 docs and can't find anything on error codes or such and I'm hoping this will help with the debugging. Thanks! Professor Mark Csele, P.Eng.

Folks, Please see this email from Chris Bailey and reply directly to him if interested. There's some really nice stuff in this collection of largely docs and maintenance spares, but also some VAXstations, cables (mostly serial BC03M/BC22D and thinwire), diagnostic floppies, VAX TU58s, a microfiche reader with quite a few fiches, and entire box of spare LS74 type chips, a bag of what looks like drive belts, rack kits for BA35x shelves, 2 BA23 backplanes, 3 boxes of 115v fans etc. I can go back and hold things for a while for interested parties but I have limited space myself these days :/ Some pix: (all between 300-600kb jpg) http://f0p.co.uk/DEChaul01.jpg http://f0p.co.uk/DEChaul02.jpg http://f0p.co.uk/DEChaul03.jpg http://f0p.co.uk/DEChaul04.jpg http://f0p.co.uk/DEChaul05.jpg http://f0p.co.uk/DEChaul06.jpg http://f0p.co.uk/DEChaul07.jpg http://f0p.co.uk/DEChaul08.jpg http://f0p.co.uk/DEChaul09.jpg http://f0p.co.uk/DEChaul10.jpg http://f0p.co.uk/DEChaul11.jpg http://f0p.co.uk/DEChaul12.jpg http://f0p.co.uk/DEChaul13.jpg There's a cutoff date of 21st April since Chris doesn't live where the kit currently is, also there's more VAX docs and probably other spares up in the loft of the house that haven't been discovered yet. Note I've already picked up the Pro350s (well, 2 Pro350s and one VAX Console) because I don't have one and I know someone else who is looking for one.

Hi, Im emailing you to see if you are interested in a load of vintage Digital Equipment Corporation computers etc. My dad has now passed away, but he was a DEC engineer for 20+years. He amassesd a whole load of DEC computers bits when he retired. We are now clearing out the garage but are not sure what to do with all this computer stuff, and just thought we'd see if anyone wants any of it before throwing it out. Here is a brief list of whats in the garage.

> A good degreaser, but not so tender on plastics. > > In the old days, I'd just use some carbon tet. Argh, I was wrong. Perchloroethylene is allowed here and used for dry cleaning, although there is a bill to ban it from the opposition in the Swedish Parliament. Trichloroethylene OTOH has been banned since the 90s. *That* smells nice too ;-) There used to be a washing device for car parts at Volvo which used hot trichloroethylene which you sprayed on the part to be cleaned. Amazing how fast it removed all traces of grease, underseal etc from a part from the front suspension of my parents' Volvo 544... The sand blasting thingy alongside took care of all the rust in short order. /Jonas

Either washing machines are designed to eat socks or else there is a spacetime warp in every washing machine. Have you read "Dirk Gently's Holistic Detective Agency" by Douglas Adams?

Lisa Test 3.0?

Steve. This dead spot problem is exactly the same problem Tony and i have been grappling with for the past couple of months! Check past posts on thiz forum.

The diskette drive was throwing a lot of read errors and making a lot of friction noise. On a hunch, I moved the pressure-pad tension spring to a lower setting (closer to the pivot). Then, I put in the MacWorks diskette. It chunked away for a while, emitted a beep and spat it out. The Macintosh "insert diskette" icon was on screen :-). Put in the Mac System diskette and it loaded to the desktop. Turns out that LisaTest 3.0 will NOT run in 512k, which might be a good data point for others in the this situation down the road. I found an AST RamStack 1M board in the other machine and put that in the second memory slot. ListTest booted without a problem and is busy testing memory as this is written. One serious issue with the diskette drive: It has one or more "dead" spots in its rotation. If it stops at such a point it fails to spin up again at the next access. When it spits the diskette out with an error, I give the spindle a small push with a screwdriver, reinsert and it picks up from that point. Hopefully folks have some sage advice for dealing with dead spots? It's not related to the excess pressure on the head - it doesn't even try to spin. There's absolutely no sound or activity.

probably OT, but still cool: found an HP large format printer on the road

by chrism3667＠yahoo.com

Can't say anything other then it's in my car. It'll be the second "plotter" I've picked up for little or nothing (I was actually a good 10 miles from "ground zero" before I realized this thing is just a big ink jet printer, not a plotter). Anyway it should be good for making large format schematics and whatnot. Doesn't everybody love those? Anyone w/docs or drivers please contact me. Perhaps offlist.

This used to be covered in the VMS FAQ. IIRC attempts to read or write to higher block numbers by the console firmware result in the address wrapping rather than an outright failure. It should be possible to arrange the files on a larger disk so that the code that the firmware needs to access for booting is located below the limit. However, this is not as easy as it sounds as VMS BACKUP restores files in alphabetical order and some of the critical bits are located under the VMS$COMMON directory which may end up getting written late in the restore. Special care needs to be taken of the dumpfile (or pagefile if used for dumping). A system crash will result in the firmware writing to it and this can be very bad news if part of the file is located beyond the limit which will cause the address to wrap and something near the beginning of the disk to get overwritten. Disks that are not used for booting or system dumps are not affected by this limitation so a system can have a small boot disk and a much larger data disk. Regards, Peter Coghlan.
