IBM disk drives

by MTPro＠aol.com

Hello, could anyone help this person out with some information or leads? Please reply to her directly. Thanks, David Greelish Publisher Classic Computing Press www.classiccomputing.com >From lorri1961(a)yahoo.com - I've been given an assignment to research and compare the differences in the IBM 350, 1301 and 3350 disk drives. I've been searching most of the moring and haven't come up with very much at all. I've checked the IBM site and find mostly current hardware. I've search several other sites and find only brief references to the devices. Would you happen to have any leads that would help me find the Platter diameter, rotation speed, capacity in MB and data tranfer rates of these devices. I'm not asking for answeres, only for possible leads to the information. Thank you for your help, Lorri

Halon dumps: a data point

by CLASSICCMP＠trailing-edge.com

A couple years ago we had a thread about Halon fire-suppressing systems used in computer rooms. Through the school of hard knocks, I just learned first hand how such systems operate. Today at work (let's just call it a "large employer in the Washington DC area") we had a memorable incident in Operations Control when someone (with undoubtedly good intentions) unscrewed the solenoid controlling the valve and dumped - without warning - 2500 pounds of Halon 1301 into the room in just a few seconds. (Operations is a *big* room. It was fitted with eight giant red tanks of Halon.) Normally there'd be a thirty-second delay as an audible alarm allowed the occupants to clear the room, but this feature is bypassed if you go straight to the solenoid! The sudden pressure from the halon dump sent numerous ceiling tiles flying, as well as large stacks of paper that were blown off the consoles. Not everyone evacuated immediately - several folks in safety-critical roles stuck around for ten or fifteen minutes until the firefighters showed up with air packs that allowed others to relieve them. Some who did stick around eventually left in ambulances (I *hope* just to run some precautionary tests.) The good news: the computers didn't hiccup at all during all this. Moderately good news: Halon dumps aren't instantly fatal. Seeing as how I spend a good fraction of my day within a couple of feet of some giant red Halon tanks in the concrete bunker - oops, officially it's called "computer room" - this is good to know. I'd been heavily trained that when the Halon dump alarm sounds, you *get out*. Now I know a little more, especially about the dead-man switch you can use to delay an electronically-triggered dump. This Halon is Good Stuff. Other than some grit blasted from the ceiling tiles, there was zero debris left in the machinery. What's the "environmentally friendly" equivalent used today? Is there such an equivalent - something that will put out a fire, but at the same time not damage vital equipment? Tim.

Systems available

by cem14＠cornell.edu

Well, my current job will be over next December and I will have to move elsewhere. Unfortunately, I won't be able to take all of my stuff with me, so I have to get rid of things. I'll offer a few things on the list first, then try to sell it on eBay. Other things go straight to eBay as I don't think that there is any interest for them here. So, here's a summary (and before I forget, location is Ithaca, New York; some stuff is at home and other stuff is at the Electrical and Computer Engineering School at Cornell). Only partial description are included; if you want to know more particulars about something please send me personal email to cem14(a)cornell.edu . So here's the list: - (1) microvax II in BA123 case, 14MB RAM, KA 630-A.V1.3, M7555, M7546, RQDX3 (apparently wiped). I had planned to play with this system, but never found a SCSI interface, I have no tape drive for it, and I could not figure out rapidly enough how to load the OS from the network (it does have a DELQA card). The case is missing one of the side covers (but the card cage is intact). The rubber ring on the wheels of the case is disintegrating. Goes through self test; when you type "boot dua0" it answers "?42 NO SUCH FILE, DUA0". I also have a maxtor XT4380 and a card that is a licensed copy of the Webster WQESD which might be handy for this system. I really want this system to go to a good home. - (1) vaxstation 2000 with 6MB RAM (I believe). I'm keeping another. - (1) Decstation 5000/125 - (1) Decstation 5000/133 Note: these decstations come with one HD bracket each, one of them has a 425MB HD with netBSD 1.4.1 . I think they both have 16MB RAM, but I'm not sure. I can install netBSD 1.4.2 if you want. - (2) Decstation 5000/33 (maxine) with 400MB HD's, 16MB RAM, one of the nicer framebuffers and corresponding monitor, keyboard and mouse. Currently with Ultrix 4.2, I think. Or was it 4.4? Anyway, since Ultrix is not transferable, the buyer should erase the hard drives. NetBSD runs in them, but the nice framebuffer is not supported (yet). - (1) Decstation 2100. This machine worked non-stop as an ftp server for nearly five years. - (4) Storage Expansion Units for above; two have the same box as the Decstation 2100, another one is in the same style of a Vaxstation 4000/60 (which I also have, but I'm keeping :-) . The last one is in the same style as the box for a Vaxstation 2000. - Lots of ULTRIX documentation for above. - (2) Sun IPC's with working NVRAM, and (2) more for parts. - (3) Sparcstation 1's and 2's, some working, some non working, one or two systems should come out of all the parts... - Lots of SunOS 4.1.3/4 docs - Many HP9000/300 systems, including a 433s with 33MHz 68040, 370, 350, 340 and 320 systems, as well as HPIB hard drives, tape drives, tapes, memory, storage expansio enclosures and other stuff that goes with them. I'm keeping a 380 system with SCSI and a 25MHz 68040. Wish I could keep the 433, but it is too big. - (4) Racks for the HP9000/300 series. If you think that the BA123 case is nice, you should see these... - (3) HP9000/720's in working condition. I can install HPUX 10.20 for verification purposes if anyone is interested. - HP9000/236 system with monitor and storage expansion box. The only system that actually has an "any" key in the keyboard :-) . No software or OS, though. - HP 1000 E-series. It breaks my heart to part with this; it is the oldest system I have and I really wanted to bring it back to life. Believed to be working, but I don't have enough expertise to test it. (Frank: I have the list of ROMS somewhere; I'll post it later). Some cables for the serial cards are included. An HPIB HD came with this machine, but it seems to require service. - Exabyte 8200 with enclosure. ... more things to come. Most things are available for a small price; others, for the cost of shipping + 20%, since I'm interested in finding a good home for them. Would anybody like to pick up the microvax II? Regards, - -- Carlos Murillo-Sanchez email: cem14(a)cornell.edu 428 Phillips Hall, Electrical Engineering Department Cornell University, Ithaca, NY 14853

DEC Computer Labs available

by Anthony.Eros＠compaq.com

I have an opportunity to get up to a dozen DEC Computer Lab units. The DEC Computer Lab was a tabletop digital logic trainer (see attached picture) providing gates, flip-flops, a clock source, switch (full throw and pulsed) inputs and lamp outputs that allowed a student to wire up various logic circuits using patch cords. These units are mostly complete (some may be missing rocker switch covers or have some burned-out lamps) but do not have patch cords or documentation and are as-is. I may be able to provide a Xerox copy of a DEC computer lab workbook for copy costs if desired. We're looking at about $200-250 per unit, plus shipping/copy costs as required. I pulled the attached picture off the web to show an example of how the lab looks, I don't have a picture of the specific units that are available. If people are interested, I can collect some bucks, pick up the units, pack them up and ship 'em out. Please contact me off list and let me know if you'd like one of these lab units. -- Tony <<deccomputerlab.jpg>>

Pentium life extermination

by xds_sigma7＠hotmail.com

Hmm, well ignoring the heat, green house gasses, etc... I see it this way: each pentium sold = more $$$ for intel, which lets them buy more companies (they apparently own the justice department already, since they're more of a monopoly than microsoft), each new company = more money = more crap by intel = soon leads to the point where I give them money every day = quickly removes my desire to live. Of course, with as crappy and buggy as their chipsets, etc. have been getting, it might be debateble whether they'll achieve total world domination or explode in their own craptacular way...

Back in my Prime days, when we got our Halon system, the salesman demonstrated it at their cost after installation. Triggering it deliberately, the result was as you describe. Additionally, boxes of greenbar that were open had the top layes of paper sucked out of the box, without breaking the perfs, sending it flying. He stood in there for 15 minutes, lighting matches which went out immediately, so we could see how well it worked. He drove away in his car, didn't crash or die. As it was explained to me, Halon is safe, but under temperatures that would kill anything organic, it can transform to a deadly gas. The joke was that the gas didn't kill you, but the reason you weren't supposed to be in the room if you had to trigger it manually was to avoid the shrapnel when the spheres exploded. > The good news: the computers didn't hiccup at all during all this.

You can buy small Halon extinguishers still, but only at your local civil airport for your plane. I have recently heard, however, that there is a replacment gas that does just as well, but can't recall its name. Does seem that it starts with an "H", though. regards, -doug q

Then, explain > the ozone hole over Antarctica, which has little need for CFCs as a > refrigerant. This is soooo far off topic... CFCs are distributed somewhat uniformly over the stratosphere. The reason why Antarctica is the location of the hole is due to climate... You need several things in proximity to "cause" the hole - A halogen ion (Chlorine and to a lesser concentration, Bromine), a place to work and energy. The place to work is the surface of certain sizes of ice crystals (high-altitude clouds) that only form at temps well below -60F. Sunlight is the source of energy. The ozone hole opens up in Antarctica every "spring" because that's when the sun rises (providing energy) and that's when the air is cold enough to make the proper kinds of clouds. By late October, it's warm enough that the clouds no longer form and the Polar Convergence dissapates, allowing the ozone-poor air over the continent to mix with "normal" air from higher latitudes, diluting the ozone over Australia and New Zealand, primarily. The way the model works, it's "natural" for the hole to open and close on an annual cycle. The real question is, how much of this is due to man-made sources of chlorine. The direct measurements show that CFCs released at ground level take several (18?) months to make their way to 30,000m. Since eventually the chlorine ion forms a stable compound, each one has a vast, but finite capacity to convert O3 to O2. The hypothesis is that more man-made chlorine in the stratosphere means less ozone. The data I have seen suggests that the more we pump out, the more rapidly the depletion occurs each Spring. For the skeptical: the above is not gospel written in stone. It is my understanding of the best explanation of the observed phenomena to date. I am not a scientist, but I did assist researchers in data collecting and reporting.

The good old british postal service 'happened' to the other CRT. They dropped it when it was being transported and snapped the wee glass guide off the back, as well as doing some internal scraping damage with the HD carrier since it wasn't fastened in properly; I had a spare case, drive and CRT so a transplant should've been really simple!

Halon dumps: a data point

The air handlers also helped in removing the halon from the room. As I understand it, during a "normal" (electronically-triggered) Halon dump, the air handlers would have been cut off to maximize the effectiveness of the Halon. In fact, I've heard that Halon's density makes it more dangerous than if it didn't stratify. Unconscious folks, unfortunately, tend to have their noses only an inch or two from the floor...

I wonder why? Probably because in many systems like Eudora, "reply to all" replies to all the addresses in the "To:" line and the sender. The "Reply-to:" takes precedence over the "From:" and is set to "classiccmp(a)classiccmp.org", and the "To:" was also set to "classiccmp(a)classiccmp.org", it gets sent twice, and Eudora is too dumb to scan for duplicates. -- Pete Peter Turnbull Dept. of Computer Science University of York

RCS/RI fleamarket and open house

by aw288＠osfn.org

This is a reminder that the Retrocomputing Society of Rhode Island, Inc., will be holding a much needed flea market this Saturday, at our Millspace in Providence, RI. See our page at www.osfn.org/rcs for directions and details. What is going? Mostly small computer stuff - lots of home computers and micros, maybe a few *nix workstations. Conditions vary greatly! Prices will be rock bottom, as we need to clear out the room for more BIG machines. We have no list - rather the list will be formulated as we pick thru the stuff. The usual bunch will be around, and any and all are invited to stick around for dinner and beer. William Donzelli

Halon dumps: a data point

by ajp166＠bellatlantic.net

>Moderately good news: Halon dumps aren't instantly fatal. It can very nearly be. It's an oxygen displacer and non combustable in itself and non posionous but it's not oxygen! It can be lethal due to oxygen deprevation. What makes it fairly safe like you saw is that it's quite heavy compared to air and hungs the floor. Those that didn't leave were in my estimation quite foolish. Many years ago one of the halon similars (freon12) was spilled in a room I was working in, roughly 35 gallons of it due to a valve left open. I was quite blue when I was dragged out of the room as it had displaced all the air and only the fact that I'd been under the HEPA curtain doing work (also why I didn't initially notice it) there was outside make up fresh air added or I'd have been hospital fodder or worse. Freon and halon are related as florinated or halogenated hydrocarbons and both are low boiling point, heavy compared to air and non combustable. They are also both oxygen displacents makeing them dangerous in closed rooms and effective for fire control (both as a mild cooant and removing oxygen) while fairly inert. I'm sure there are varients of R134A in use or similar still used. Allison

DECstation 5000/200 battery backed NVRAM failure?

by cem14＠cornell.edu

Hi Sean; These Decstations have a window in the back through which you can see eight small LEDs that display diagnostic info when the system goes through POST. Is there any activity in the LEDs on power up? If so, what is the last pattern that you see in the LEDs? Note that in many Decstations of this kind, the cpu runs too hot due to inadequate cooling and they die. I've had this happen twice. > Date: Tue, 12 Sep 2000 16:58:47 -0400 > From: "Sean Caron" <sean(a)techcare.com> > Subject: DECstation 5000/200 battery backed NVRAM failure? > > Just wondering if anyone knows if this could be a possible problem with = > this type of machine. > > I have two DECstation 5000/200 systems.

DECstation 5000/200 battery backed NVRAM failure?

by sean＠techcare.com

Just wondering if anyone knows if this could be a possible problem with this type of machine. I have two DECstation 5000/200 systems. When I got them, one powered on but did not do anything (no output on serial console on port 3), while one would work fine (console output on port 3, seemed to be functional, etc). I did not have any external SCSI storage for them at the time, so I decided to store them until I could make use of them. About a week ago, I finally got a SCSI drive enclosure to mount a disk in, so I decided to try getting one of the systems up and running with NetBSD/pmax. To my surprise, however, now both of them do nothing on power-on! I had not touched them since I had power-on tested them a few months previous, so I was at a loss as to knowing what had happened. The only thing that I found that I even remotely suspect could be at fault is what looked like one of those Dallas battery-backed clock/NVRAM chips. I was wondering if perhaps the battery had died and this was preventing the system from coming up. I was hoping someone else might have run into a similar problem and might have a few pearls of wisdom to share. Thanks, -Sean Caron (root(a)diablonet.net) | http://www.diablonet.net

Mac SE screen

by agraham＠ccat.co.uk

Hi folks, In trying to make 1 good SE out of 2 bad ones I managed to send the screen to decompression hell while unbending a bent pin on the yoke.....grrr.....so, before I start dismantling other dead Macs the question is can I use the screen from either a Plus or Classic? And obvious 2nd question - anyone want the bones of an SE for possible macquarium use or something along those lines? There's only the case, PSU, dead screen and analogue board left though. cheers! adrian/witchy www.binarydinosaurs.co.uk - 80's computer collection

GA 3345 safe

by geoffrob＠stmarks.pp.catholic.edu.au

Hi guys & gals, Passed on the responses from the group here to the guy in Qld regarding the GA 3345. It jolted his interest level, and it appears it may have a safe home already. Got the following response. Quote:- "I just rang the guy from yesterdays generally distributed e-mail and he says that the unit has absolutely no documentation, nor any sign what operating system it ran, and he is only guessing by saying it is over 25 years old. He has been approached already by the "museum" run by the UQ Computing department and they have indicated they will take the complete thing off them. (This museum is just a collection of PDP and other early stuff in the foyer of one level of their building). Currently it is in the Qld Dept of Natural Resources Offices, Brisbane, and was being held by someone starting a surveying museum, but they realised this had nothing specifically to do with surveying. He has said he will contact me if the UQ offer falls through." End Quote. Just to make sure it won't become razor blades, I've made a firm offer to take it if the UQ proposal does collapse in a heap, just in case......

You put in another MVII board (or even a MVII and matching ram) and keep trucking. Anyone whos wored with vaxen would know this. The system HWID is not a serial number that I'm aware of but a model/product ID so that VMS (or Ultrix) "knows" a bit about the processor (or chipset) and it's busses. >Another example would be what if I want to move this app from a MV2 to say a >VAXstation 4000/VLC as I've got space problems and I want it to run faster. >Of course this example is of questionable legality since you're licensed to >run this app on a MV2. However, the first example should be perfectly legal >and something you'd want to be able to do. Ignoring the license issues if the media for both were say a scsi disk it would run on any scsi equipped vax. My MVII has CMD SCSI, I build a 5.4 copy and backup/image it to a second drive which is removed and placed in a MV3100... runs fine. Same for V7.2. VMS if memory serves is not licensed to the specific CPU but to the total users and per CPU used. So if you have a MVII and upgrade it to a MVIII the license is still valid and all. Now if you take the old MVII boards and build another system you will be technically required to obtain another license. Most VMS based layered apps were the same way. This was a pet peve of customers as the MVIIs were cheap and the bigger machines werent but the license was not based on if it were a MVII or VAX9000 but by the number of users it could serve and if it was a cluster member or cluster host. At the time (likely still) it was a $3000 license and for some users that was chicken feed and others that was the whole farm. At times(through the '80s) DEC didn't realize how valuable their software was and often acted like selling hardware was all of it and software was one of those annoying things you did to sell hardware. By the '90s hardware and software were often bundled and used to drive sales of each other. Allison

All of these would have different handshake and >setup information. I don't know how you'd be able to have >anything that you'd call standard. Wrong. The standard devices were usually AY-3-1015/COM2502 based and tended to use the MITS status bits and IO addresses. Mits never used the 8251, and the 8250 was later to the scene. MITS set a standard in as much as there were very few then by sticking to the 2sio standard or the SIOB standard for serial ports with the SIOB being a uart like ay-3-1015 and the 2sio using 6850s. Expereince says, the common usart like the 1015/com2502 was most widely use with the 8251(9551/2651) the 6850 running follow on. The only S100 board I've seen the 8250 on was the CCS. The 8250 was not a widely used part in the late 70s on S100. I'd be quick to point out that the mits era was 1975-1977ish with other players already emerging as new leaders (NS* horizon and friends) by late 1977 in the S100 space. From 77-80 that would again undergo major changes going from the MITS/IMASI front pannel style machines to the Northstar*, CCS, Compupro turnkey style front pannel less and disk based systems. It was also simple enough at the time to fix IO in most code as it was trivial in construction and easy to find in binaries. allison

VAX panic - buried models?

by ajp166＠bellatlantic.net

From: John Allain <John.Allain(a)donnelley.infousa.com> >The HWID I speak of is a Unique ID per individual CPU. True. And it identifies the basic hardware and CPU. >Think relicence. Keep in mind the basic "kits" carry no license or other machine locked stuff. The license is applied during or after the install. Even then I've built and installed systems on my MVII and then carried the media to the MV2000 as both bootable and complete (even licensed if that is within the written license terms). That was how we cloned VMS sustems at DEC as it was faster than using TK50 tapes. I've put the VMS 7.2kit (cdrom) on everythingt from MVII and VS2000 through 3100m76 and would expect it to load and run on most any other VAX as well. The biggest problem of installing on older hardware is the minimum system (ram and disk) has grown during the years and early version coulld fit on 30mb disk and 1mb ram that has grown to over 150mb disk and 4mb ram. Though it is possible to shoehorn the latest version is to less than the specified disk and ram it is a exercise fort the experienced and will produce a system of limited utility. >So, Any old copy of VMS can be relicenced for a >matching or nearly matching architecture machine? Well since all VAX are by definition matching hardware there is little issue. However there are exceptions like the RTVAX which is not totally cpu compatable VAX and differs in the translate tables, it never ran VMS. >Tell me, is that through Montagar? The VMS7.2 Hobbiest version is available there. Note HOBBIEST version does not mean stripped or limited. It means it's packaged with many hobbiest desireable packages besides VMS itself. >P.S. Can users fo VMSbuilds? VMSbuild is a standard utility and is used often to configure custom installs once you have a configureation you want to standardize on. Anotehr useful VMS utility for small systems is VMStailor which allows trimming off or adding in libraries, fonts and other peices to tailor a system. Allison

Even then the CPM bios only hid the underlying IO with standard interface and the IO could litterally be anything on the map (often was). If anything the idea of canned IO was something unique to systems like the SOL and a few others and rare in the s100 world. Allison

VAX panic - buried models?

by ajp166＠bellatlantic.net

From: healyzh(a)aracnet.com <healyzh(a)aracnet.com> >It *might* run, however, V6.2 was the last version of VMS to support an >11/750. Just like V7.2 will be the last version to support the MV2 family. First a word from... When DEC says Support they mean assitance not it will not work. Support is a service they provided and if it's supported you could under your support contract call and expect help. If it was not supported it will likely run but don't call DEC support if it doesn't. So that means prior to MV2 is not "supported" but the drivers are likely there and work. I'd expect a 750 with RA81 and 8mb ram would run V7.2 just fine. But if you ask around older 6.2 and V5.5 kits arent that hard to find. Their owners will likely let you borrow them as it's up to you to get your own license pak which is not tied to the media. I have it on good word that V7.3 does still run on MVIIs. Allison

All of these would have different handshake and >setup information.

Using Altair BASIC, BASIC polled the switches (at port FF) in order to determine which ports to use for various I/O. Disk BASIC was the choice (running over CP/M), the BIOS would have to be recompiled with the proper port locations for the hardware one was using. What I was kind of getting at was as follows. If I wanted to provide emulated console I/O, what port would I virtualize so that any software I loaded would run? I guess that my PeeCee-centricity was showing a bit in that in the PeeCee certain hardware ports were always at the same location. So, the conclusion is that if I want to emulate a single console port, I have to select which serial board to emulate (the 2-SIO for example) and virtualize ports 20Q and 21Q. It also sounds like that I need to trap input port 0xff as the "sense switch" port. This may be done in the emulator already; I have to check.

Hi There was no standard port used for serial I/O. and even if there was, the device could have been a AY-3-1015, a 8251 or a 8250. All of these would have different handshake and setup information. I don't know how you'd be able to have anything that you'd call standard. Dwight

Palasm?

by Jgzabol＠aol.com

In einer eMail vom 8/9/100 3:17:33AM, schreiben Sie: << I've used it since the early '80's but my work has hovered over the low-end capabilities of the language. Now that it's obsolete, I'm trying to make up for all the stuff I didn't learn when it was mainstream. I've had people tell me about features I've never even read about, and there are plenty of them that I haven't used and HAVE read about. It's pretty simple if not compact, to do everything with logic equations, and that's what I've always done. Now I'm trying to catch up on the built-in state-machine dialects. They use several constructs which have carried forward, somewhat, into Verilog and VHDL, but not in the same way or with the same syntax as PALASM. >> It occured to me that the quite modern and today mainstream language Abel has somewhat similar constructs, and is part of most modern electronic CAD systems. While having retained quite some similarity with PALASM, it may be closer to today's tools like VHDL. Regards John G. Zabolitzky

Metcal Soldering stations

by nerdware＠laidbak.com

As Zane mentioned, he's getting a used Metcal SP-200 station to play with. I also know this because he got it from me..... For those of you who don't know, these are professional-grade induction-heating systems with extremely light handpieces and dozens of interchangeable tips. Heat is practically instantaneous, and they are also static-free. They also run about $400 new. The surplus shop where I work during a goodly portion of my free time has a limited number of power supplies and handpieces available, unfortunately, no tips or stands. We got them from an electronics plant that shut down. Tips range from about $15 up to $30 new, I think, depending on the tip. If you're interested in one, email me off-list and I'll let you know what we have. These are great irons -- I have two (one at home and one at work) and absolutely love both of 'em. I hung up my Weller and my Ungar when I got the Metcal. Thanks. Paul Braun WD9GCO Cygnus Productions nerdware_nospam(a)laidbak.com

Altair Emulator enhancements - progress report - questions

by RCini＠congressfinancial.com

Hello, all: Just a quick update on my progress with enhancing the Altair Emulator. I also have an activity log on my Web site which all can view. Most of what will go on over the next few weeks is code testing as a complete recompiled "altair.exe". A few notes: - The emulated paper tape punch code works on a standalone basis and has been integrated into the overall emulator. This is the code I need to bang on. - I wrote a bus I/O emulation Windows DLL to handle actual I/O through the PeeCee's parallel port. I still have to build a little test jig to connect to the port (an inverter, a latch, and a bus transceiver). This gives the emulator 8-bits of external address space and 8-bits of I/O with *ALE (latch control) and *R/*W signals. The way this is setup, the parallel port is still shared with other Win32 processes. If this doesn't work for the emulator, I'll have to write a dynamic virtual device driver to gain exclusive access to the port so long as the Altair is "on." - In a few weeks, I'm going to tinker with console emulation either through capturing a physical communications port that has no underlying hardware (like COM5:) so that a Windows terminal program can "connect" to the Altair Emulator. Alternately, I may try just building a virtual-VDT into the emulator. - Other enhancements will hopefully include a virtual floppy drive and the ability to "install" ROM. One I have the base code stable (it now compiles/links with no errors), I plan to make the binary available for testing and the source available for review. Some of the punch code could benefit from optimization, no doubt. I also have some questions of actual users of the Altair. I wanted to use a copy of Palo Alto Tiny BASIC on the emulator (because that's the BASIC that I have), but TB relies on CP/M for console I/O. Regarding the original Altair BASIC, did the BASIC code provide its own I/O services or did it use CP/M also? What port locations were generally used to service serial ports used for console I/O? Does anyone have a working set of CP/M binaries that I can load into the emulator? Again, any help is greatly appreciated. Rich http://highgate.comm.sfu.ca/~rcini/classiccmp/

VAX panic - buried models?

by ajp166＠bellatlantic.net

I can think of reasons why not. namely enough ram and enough disk as the minima is 4mb ram and 300mb disk though you can get by with less. Most 750s have enough of both. With 8mbram it runs fair with 12 it will run good.

All I do is use a machine that I can do a VMSbuild on to my spec, no biggie. The biggest issue with recent copies of VMS is device support for acient devices. The key here is SUPPORTED as een unsuppported acient device drivers are often included. >Anybody know if: > All VAXes have HWIDs? Even micros? Yep, and yep. > Is it possible for some Third trusted party > to permit back revision VMS copies to run > on different copies of HW with other CPUID's? Why? old copies of VMS are still around and they are not locked nor are new ones. You only need a license pak. DECs use of HWID was to make sure there was hw/sw support for things like what ()-float types the machine supported and what instructions needed trap emulation. Newer versions lise all older machines and the only case where thish could be a problem is if you were trying to run V3.6 on a VAX10000 not the reverse such as 7.2 on a 11/750. Allison

Thanks to all for giving the information on the needed power supply and batteries for the HP 110 Portable Plus (it is indeed the Plus). In particular, thank you for correcting the power output of the 82059D as being 8v AC under load. (My source for it being 6 V was from Mike Simms FAQ on the HP1xx series of personal computers -- he has it in there as 6 volts -- so someone may want to have that changed.)

My initial contact with CVSI regarding a special licensing procedure for preservationist has seemingly not been taken seriously by the licensing department. At this point, they continue to view licensing of Primos et. al. as a revenue stream. This is most strange since it has been determined that CVSI does not own any intellectual property rights for anything Pr1me related. Those rights remained with Computervision, and are now property of Parametric Technologies Corporation (PTC), who is probably unaware of what they own. So preserving Pr1mes at this point in time remains a black hat activity. :-( -dq

Compaq sets final order dates for VAXen.

Having current and semi-current manuals kicking around isn't really the issue though. I've seen more PDP-8, PDP-10 and PDP-11 era manuals outside of COMPAQ/Digital/DEC than I ever saw inside. For VAX, PC and Alpha material the situation was much better inside. I wonder how many VAX hardware manuals will still be available internally to COMPAQ in maybe ten (or five) years time? Antonio

Semi-OT: Soldering Iron recommendations

by healyzh＠aracnet.com

OK, since I now have two pieces of equipment I need to get a decent soldering iron to work on, I'm wondering if people could make any recommendations. I'm needing it for my PDP-8/m front panel, and for the DEC VR260 I want to revive. I'll probably pick it up from Fry's this weekend. I'm thinking I want a WES50 Weller Soldering Station, as it looks like a good balance between cheapness and high-end. Of course anything would be a good replacement for the el'cheapo 20 year old Radio Shack Soldering Iron I've currently got :^) I've got to admit that the WSD80 looks nice though. Oh, in researching this I ran across this web page that might be of interest to people, "Basic Soldering FAQ" http://www.epemag.wimborne.co.uk/solderfaq.htm Zane

Great New Find: Olivetti L1 Computer

by pdp-11＠swbell.net

I just picked up an Olivetti L1 Computer at Goodwill. The CPU, keyboard, and disk drives are in one unit, kind of like an Apple III. The monitor is seperate, and gets its power from the main unit. All the main keys have BASIC statement on them (PRINT, OPEN, INPUT, etc...). When it boots up, it says: Bootstrap Loader Version 1.0 Insert Disk And Press Enter. Does anyone know anything about it? I couldn't find any information on the internet. Does it have BASIC in ROM? If so, how do I get to it? If anyone has any disks or manuals, that would be great! Thanks, Owen

Epson HX-20

by mark_k＠iname.com

Hi, I picked up a couple of Epson PX-4 handheld/laptop computers a few weeks ago. Have not got around to testing them yet. Any identifying text which used to be on the rear labels is no longer there. There is space for a plug-in device/cartridge on the righthand side above the keyboard. Both computers have what appears to be a 1 megabyte static RAM cartridge (possibly battery-backed) in this space. These must have been quite expensive when new. I opened up one of the cartridges. Text on one of the PCBs inside mentioned (from memory) POCKET COMPUTERS LTD 1993, so these are quite recent. In the EPROM sockets underneath the computer is some kind of auditing program; the label read Pocket Computers Ltd AUDITOR V5.2 The labels also mention CP/M 2.2. A web search for "Pocket Computers" Auditor didn't turn up anything. Does anyone have any information on this company? -- Mark

Zilog Z-80 Developement System

by rigdonj＠intellistar.net

After a lot of negotiation and long delays, I finally picked up a Zilog Z-80 Developement System today. There are two large boxs in the system, one has two 8" floppy drives and the other has the main electronics. There's also a pod connected to the electronics box by a cable. Does anyone have any manuals or other information about this system? The only thing that I have is some Zilog brochures for it. BTW stickers on the disk drives are dated late 1978. I'll try to post a better description and pictures next week. This weekend will be taken up with the Melbourne hamfest (Yippie!) Joe

Zilog Z-80 Developement System

by rigdonj＠intellistar.net

I checked on my unit's. They're blue with a biege band about 2 1/2" tall around the top. The name plates have a brushed aluminium finish. The CPU box is a model "ZDS" and it's also marked "1/40- 32K CPU" and "05-6013-01" and is serial number 26. The disk drive unit is marked "05-6013-05" and "1/40- 60K" and is serial number 275. I found a 32 sectored hard sectored disk in one of the drives. It's marked "PTR V7" "DO - T" "1-40" "5-12-82". Joe > >>I've got a Zilog MCZ Z-80 development system and RIO operating >>system disks.

RCT Swap Report (Long)

by kyrrin＠bluefeathertech.com

This year's Radio Club of Tacoma (WA) swap was both a miracle and a disappointment. It's rare that the two go together, I know, but it did in fact happen that way this year. I claim "appropriate posting" to the list for this because what I brought back is over ten years old, and can most definitely be used to troubleshoot computer systems. The miracle: Every so often, someone will show up with one or more pieces of hardware or test gear that are incredibly useful, are either working (but may be out of cal) or have only minor problems, are priced to move rather than at "E-pay average," and where the seller has little knowledge of just what it is they're moving. Such was the case yesterday morning, and the fact that I had gotten seller space this year, and was as a result able to walk around the place before they let the general public in, is the key reason I think I scored the following for all of $250. Two Tektronix digital scope mainframes: An 11401 and its GHz-capable counterpart, an 11402. Along with said mainframes came a total of four 11A32 plug-ins (two-channel vertical, 400 MHz official spec, but you know Tek always rates conservative), an 11A72 (up to 1 GHz two-channel vertical, 50 ohm inputs), and a big operator's manual about 2.5 inches thick. After I picked up my jaw off the floor, and wrote the guy a hasty check, I found, in the operator's manual, a postage-paid reply card from Tektronix that offered a free service manual for the whole works simply by filling it out and feeding it to the nearest USPS drop box. The 11401 mainframe had only one minor problem: It failed it's self-test at the A/D converter section. Said problem was completely cured by the simple expedient of disassembling the unit, vacuuming out the dust, and reseating the few socketed chips on the analog board. As for the '402, I'll try the same tactics on it 'cause I don't think anyone's tried it as yet. It's fine for the first hour or so. After that, if you power-cycle it, you get a failure in the timebase section for the 20 MHz clock. If you let it cool down a while, the failure goes away. I wager 1,000 Quatloos that this is another case of 'press the chips back down and vacuum.' Even if it's not, it still sounds like a minor part. As for the plug-ins, two of the four 11A32's fail their self-test with gain calibration errors for Channel 1. I'm not sure what's causing this, but I hope it's minor. My only other complaint: The '402 has some light screen burn. Fortunately, the CRT is nothing really special: Just a mono-green tube made by Mitsubishi. Bet I could even find a generic replacement. And now, the disappointment(s): The event was supposed to go until 15:00 local, but by 13:15 or so, everyone but the commercial sellers had cleared out. Also, the event itself was not well attended. I'd be surprised if we broke 1,000 people the entire day. As for variety of stuff, that worked out pretty well, but even here in the NW I'm starting to see less of people that want to tinker, and more of people that just want to 'plug-and-play.' I base this on the fact that I saw a LOT of "interesting" items in terms of older test gear, but practically none of it sold even though the prices seemed pretty reasonable (to my eyes). There was more than adequate seller space (three buildings worth), but the buildings were separated by several hundred feet of distance, and required considerable walking to cover. While the walking itself was not a problem, I found it annoying that everything was not all in one place, as it is with most other swaps. Finally, I think the club's timing was bad. There was a major computer swap meet (the AM Northwest people) held in Kent the same morning as the RCT event. They even started at the same time. I'm sure this was a drain on attendance because I've been to the AM-NW events, and they definitely run all day and are often quite packed. I'll be forwarding feedback to RCT on the above, along with suggestions for better timing and some other minor improvements.

MITS had nothing to do with DEC or RSTS11 OS. So my guess is they were user submissions of some basic programs not the MITS basic (billy gates would have fits over that one too). Also MITS never did anything with 8008 that I ever heard of. >So, for starters, does anyone KNOW what these are? Any informed guesses >beyond the obvious?

Some Interesting Paper Tapes

by r.stek＠snet.net

Maybe I got a bargain, maybe I didn't. Help me decide. I won an auction for three paper tapes in excellent condition. All three are labeled with a DECUS sticker (and the main DECUS site is re-organizinf its software section, so there's no info there). All three have typewritten RSTS11-75 on them, then one has 8080.Bas 2/June/76, one has 8008.Bas 2/June/76, and the third has 8008.Doc 2/June/76. Supposedly these all came from MITS. Right now I don't have a paper tape reader (Doug Quebbeman has mine, and I haven't interfaced it to my Sol yet anyway). So, for starters, does anyone KNOW what these are? Any informed guesses beyond the obvious? Can anyone read them for me or make copies in a more "modern" format (i.e., CUTS cassette tape)? Bob Stek Saver of Lost Sols

I plead stupidity: I should have put my glasses on before reading the front of the adapter. Have to admit I wondered how it thought it could fit 3A down those skinny wires that go to the output plug. BTW, the Fedco battery packs (3x Gates Cyclon cells in series, held together with a big piece of heat-shrunk tubing) that I got from iGo do work. I've ordered another batch from another online seller (trying to save a few bucks) and will post a note when they've arrived and I've had time to install them. -Frank McConnell

Stuff for free and sale

by spectre＠stockholm.ptloma.edu

Hi: Well, it's time for spring^H^H^H^H^H^Hfall cleaning, some for free, some not. I have a Prowriter dot matrix printer in unknown condition (cosmetically good). Free to the first person who picks it up. No, I will not ship it. I'm in San Bernardino, Calif. area. It's too big for me to keep now that I have a new Panasonic 24-pin printer for the C128. It will go to the dump in a couple of weeks if unclaimed. I also have two Apple monitors; one, a composite monitor designed for the IIgs (but works with any Apple II), and a small RGB monitor that went with my Mac IIsi (15-pin). Both work 100%. I'd like to trade for, in particular, M100/NEC8201A RAM modules, but am asking $25 apiece or best offer plus shipping. Priority goes to anyone who can pick them up, since it saves me having to drive them to the post office. I have Commodore monitors coming out my ears and since they can take S-video and analogue RGB, they're much more useful to me than these Apple ones. The monitors will go to eBay in a couple of weeks if unclaimed. I'm also not taking any of this up to VCF since I'll be dragging enough up with me (an SX-64, a Tomy Tutor, several Commodore monitors for them, all the peripherals for the Tomy ...) -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser, Point Loma Nazarene University * ckaiser(a)stockholm.ptloma.edu -- Room service?

These may not be compatible with the DU-15LU drive, assuming that drive is for computer data storage and not video recording. Try to compare pictures of the two types of disks. Panasonic/Matsushita used to make optical disk video recorders for the professional market that used 8" disks. The model numbers of the recorders and players begin with TQ-, so I suspect the TQ-FD22 disks are for the video recorders. FWIW, going to eBay and searching for Panasonic TQ should bring up some listings for the players/recorders. TQ-2026F is a player/recorder, and TQ-2027F a player. The recording method used by these might be analogue given their age. -- Mark

recycling finds - big iron - anyone interested?

by west＠tseinc.com

I stopped by a recycling facility today that I had forgotten about as a possible source. Here's some of the items they had, if anyone is interested contact me off-list for particulars. Amdahl - 9406, 6690, 6395. Many of each, about 12 cabinets altogether. The cabinets were mostly gutted, but the panels were still there. Several pallets of hard drives were removed but they still have those too. IBM - 3088. Looks complete. They also had a 4300 that had been stripped to virtually just the frame. Probably no interest there :) DEC - a 11/73 chassis only w/power suppy and front panel. A microvax II. An 11/83 turbo. Plus, the following dec modules: M7516-YM, M7555, M7546, M7606-AF, M7622-AE, M7625-BA, QBUSBEC37 Jay West

Processor Technology had a HD system they called "Helios", which used (IIRC) Micropolis hard-sectored disks (they may have been "firm-sectored" tho). I think most went the NorthStar route, tho. I had intended (and still hope) to get a Morrow/ThinkerToys Discus 2D system for my Sol. hth, -dq

power supply for HP 110 Portable Plus ?

Unfortunately it lacks the external power supply/ > recharger, so I don't know if it works. Model 110 is the "HP Portable": 16-line screen, Bell 103 (300 bps) modem, and no drawers (the RAM size and built-in application set are fixed). The "Portable Plus" is usually called that, or "110 Plus", although it has the unwieldy model number of 45711. The power supply that you probably want (being in North America) is HP p/n 82509D: it's the same thing as used for a lot of HP's portable computers, and I think the 41C rechargable battery pack. (There are other variants on this for places with other input voltages and/or mechanical wall outlet configurations.) Output is 8VAC, 3A, which should be applied to the two pins in the rectangular socket on the back of the Plus (not the trapezoidal ones which are HP-IL connectors). If the Plus doesn't hold a charge, the battery is replaceable. -Frank McConnell

power supply for HP 110 Portable Plus ?

by rigdonj＠intellistar.net

Kevin, The charger output is 8 VAC. I don't know the current rating but it's probably about 100 or 200 Ma. HP uses the same charger for a lot of different things and they can often be found in surplus stores. The part number is HP 82059. It's a wall wart that's about 1 1/2" on each side.

The measurement/instrumentation half should have kept the HP name. The agilent oxymoron actually fits the other one. Carlos.
