vintage HP-87 system with additional equipment

by daspage＠yahoo.com

Hello, I got your email off of your website and I was hoping that you could help me The company I work for here in the great northern state of Maine decided to clean out the server room one day and was going to throw away a great piece of computing history so I rescued and took it home I had done some research and I know there is some demand for this type of computer among collectors . is there a website to find out possible market value and maybe a buyer? This is what I had acquired: Hewlett Packard- HP-87 HP82909A-128k Memory Module HP82929A-Programmable ROM Module HP82936A-ROM Drawer w/ six (6) ?ROM chips?(?) 1. Plotter ROM-Rev. A 2. I/O ROM- Rev. A 3. Advanced Programming ROM 1- Rev. B 4. Advanced Programming ROM 2- Rev. B 5. Electronic Disc ROM- Rev. A 6. Assembler ROM- Rev. A HP82939A-Serial Interface HP9121-Dual 3-1/4? Floppy Drive HP82905B-Printer (Dot Matrix, I believe) Ten (10) Floppy Disks, (to be named later if needed) Pocket Guide Instructions... File folder w/ original invoice for parts of the system and misc. paperwork.. The HP-87 works well, I plugged it in and was able to type commands, nothing too complicated .i didn?t test the floppy drive or the printer yet I need another power cord which I can dig up system is clean, though slightly (very slightly) discolored from age Please let me know if you have any resources for me to follow up on I have considered posting it on Ebay, but I would like to get more info on it before i do anything in the meantime, I will check it out and see what it can do!

Early RAID

by Steve＠OceanRobots.net

Hi, Posted a few days ago looking for early, circa 1987 implementations of RAID beyond RAID0 and RAID1. In my research, I've come across a fellow named Jan Janku, who proposed some advanced ideas in 1986. Does anyone know of him or where I might contact him? TIA for any response, steve

Not classic, but free: HP-UX (and the B2000)

by compoobah＠valleyimplants.com

www.openpa.net is your friend. Don't have anything that new; a C180 will run standard kbd/mouse and perepherals just fine. What graphics do you have? HP jumped on the next big thing, the EVC connector, really fast. I don't think anybody else did. Finding an adaptor can be fun-. The newer FX5/FX10s I believe have DVI, though. The apps disk does appear to contain cc and cxx. Don't know if they have fixed license policies in place or if you just are asked nicely to get a license from HP. To do that, you either (a) get a commercial software product for HP-UX developed or (b) you send them a check for about $900. HP-UX does have all headers, so GCC is an option if you have cycles to burn (don't even think of using anything less than GCC 3.3 - it seems to, um, "pessimize" programs on RISC architectures) I'll play around with the C180 and check out the apps- I have more disk space there (wohoo! 6GB!)

Since the PSU is located separately, the heat it dissipates would be outside of the machine. Even though the PSU is capable of supplying more power, it will only output the power that is needed. I would take off the top lid of the computer and try to pinpoint where exactly the heat is coming from. There could be some components that might have shorted out and is causing the power supply to output more current. This could actually be your original problem. The old A600 PSU probably wasn't able to handle this current draw but the more powerful A500 PSU could. If something shorted out (like a resistor) it would cause other components to heat up and that might be what your seeing. Amiga install any fuses in the computer I have no clue. Wouldn't have cost that much extra." Regards, Andrew B aliensrcooluk at yahoo.co.uk

Ok, here's the full story : I have had my Amiga 600 since 2001 and have added a few bits over the years: - 2.5" 4GB harddrive (I can't remember the make and model at the moment) - 1MB RAM (in trapdoor underneath) I also have a 4MB PCMCIA RAM card which is rarely used, and 2 external floppy drives (one doesn't work), with only 1 connected up. I haven't upgraded any of the kickstart or ROM chips, they are the same as when I bought it. I run WB2.05 (and am happy with it) with kickstart 37.300 I don't know the board revision number off-hand but I can find out if required. My harddrive used to power down (powersave?) after not being used for say 20/30 mins and happily power-up again whenever I tried to access the drive (via WB or via AMOS BASIC). However, around April/May this year the drive started to randomly power down and then, usually, almost instantly power back up again but WB nor AMOS could access the HD. Any attempt to do so would freeze WB or AMOS. I figured (as you would) that my harddrive was playing up, so I copied all the important files to 26 floppy disks (fun!) - 880K each, you see. A mate (Scuzz, who owns the http://www.commodore-amiga-retro.com website and the equivalent yahoo group), and die-hard retro (especially Amiga) enthusiast offered to use my HD as a slave and copy the files, as best he could, to his PC and burn them to a CD for me. In the meantime I got myself another HD, which happened to be the same make as my last one, with WB3 on it (it has a Locale folder, files I didn't see on WB2 and a 68040.Lib file). This new HD has exactly the same problem :( I popped along to www.amiga.org and posted my problem up there and peeps then suggested it might be a flaky PSU. I got myself an A500 "heavy brick" model (AFAIK it's compatible and gives more power if required) by chance (I was planning to get another A600 PSU) >from www.amigadeals.co.uk Everything appeared to be fixed. However, my A600 was running hotter than normal. I have always put a plastic pen above the air vent bit at the top of the machine (by the F1-F4 keys) an d it used to always be cold. With this new PSU it was warm and the underside of the Amiga 600 was hotter than normal. I posted my concerns to either Amiga.org or CAR and then someone suggested that it might be a faulty resistor. He claimed that the A600 PSU didn't have enough power to supply the machine with a faulty resistor (thus causing the HD to shutdown temporaily) and that the A500 PSU did, and the extra draw from the board (caused by the faulty resistor) could be sustained by the A500 PSU, thus causing the extra heat. (I could look up what he said and quote it tomorrow, if it helps?) Phew! I hope that all makes sense. >> snip << > [...] > > > I also have recently started becoming > > interested in the TRS-80.

Did anyone other than Motorola use VERSAbus in their products? I get the impression that a few companies bought into the standard, but I'm not sure if it had morphed into VME before anyone seriously used it. (I picked up a Motorola 68000 SBC earlier that has a VERSAbus interface on it, hence the interest) cheers Jules -- A. Because it destroys the natural flow of conversation. Q.

by steerex＠mindspring.com

Hey guys, OK... I went to the site and completed the application. At one point during the "signup" process, the server choked and could not complete the process. I never did recieve a "comfirmation" screen or a DOWNLOAD / CD option . I did however receive an email with a "software delivery receipt" including the download key. When I went to the URL, I was given an option to download the app. I'm using dialup so downloading is not an option. Do I have to complete a different request or will the CD's automatically be sent? Thanks, SteveRob

Hello Dwight > Please try at least one of two experiments. Either actually measure > with an inductive load or do a simulation. For a transformer, zero > cross is the worst time to start. Why? What do you expect to happen? At zero crossing there is no volts and no current will flow. The current will start to increase as the voltage increases and continue to do so until the next zero cross point. > Don't confuse steady state action with the first cycle. The response > is not the same. Agreed. At the first cycle there is no energy stored in the inductor so switching it on at zero cross gives a circuit with no stored energy. > With an inductive load, this is at 90 degees, or peak > voltage. This is also the best time to turn it on. If you turn on an inductor at peak voltage you will get a magnetization offset that may take many cycles (approx LR) to decay. This gives a peak current that is much greater that that from switching on at the zero cross point and is clearly not the best point to turn it on. Lee.

by sellam＠vintagetech.com

Sorry for the OT posting, but I figure I'd find some qualified Unix techs here. I have a client in the Springfield, Missouri area that needs to get some data off of a very old SCO unix box. The box is not interconnected with anything else, and the only means to get data off--an old Irwin 60MB tape drive, went bad. I figure there would be a simple way to get the data off the hard disk, by either mounting it into a Linux box or adding an external drive to the SCO box via SCSI (though I'm not sure if it has a SCSI interface...in fact I know next to nothing about the box currently). If anyone is interested in this project, please e-mail me directly (I won't see any responses to the list). Time is of the essence, so please reply soon. P.S. VCF 9.0 is November 4-5.

OT: Purina Diet

by rigdonj＠cfl.rr.com

Subject: Purina Diet Purina Diet I was in Wal-Mart buying a large bag of Purina for my Labrador retriever and was in line to check out. A woman behind me asked if I had a dog? On impulse, I told her that no, I was starting The Purina Diet again, although I probably shouldn't because I'd ended up in the hospital last time. But that I'd lost 50 pounds before I awakened in an intensive care ward with tubes coming out of most of my orifices and IV's in both arms. I told her that it was essentially a perfect diet and that the way that it works is to load your pants pockets with Purina nuggets and simply eat one or two every time you feel hungry & that the food is nutritionally complete so I was going to try it again. I have to mention here that practically everyone in the line was by now enthralled with my story. Horrified, she asked if I'd been poisoned. I told her no, that I'd been sitting in the street licking my butt when a car hit me .

Lobo's Max-80

by aliensrcooluk＠yahoo.co.uk

Hi all, Basically, I bought a bunch (40) of 80 Microcomputing magazines which are in pretty much mint condition. Every so often I type up interesting articles and post them to a couple of groups I am a member of. Since I am new here, I don't know whether this is allowed or not. If not, just let me know. A long read, but quite an interesting one. I was trying to keep this short, but I ended up typing up most of the article! Source: Page 122, 80 Microcomputing #42 (July 1983) - a Wayne Green Publication. Ignoring the adverts, the full length article about Lobo's (or Lobo Drives International, to give it it's full name) Max-80 computer is 4 pages long and is written by R.A. Langevin. I have attempted to give a summary of all the interesting bits. Read on.... Lobo Systems' Max-80 is an 8-bit microcomputer that supports LDOS and CP/M; has an impressive array of storage options, including floppy and hard disks; serial input/output; and both serial and parallel printer ports. In terms of versatility and performance per dollar, it's unquestionably a best buy in todays marketplace. The system is a natural upgrade for [TRS-80] Model I owners since it offers CP/M while preserving their investment in disk drives and in much of their software. It is also completely at home in a business environment. Not everyone, however, will appreciate this computer. Serious game players will find they can't use self-booting disks in the machine [what the?!]. In addition, although Model I graphics are supported and limited graphics are available in the CP/M mode, the Max-80 cannot presently display full-screen, high resolution graphics, a deficiency that makes it unsuitable for some business uses. The Max-80 is basically a single-board computer housed, with it's power supply, in an attractive, ivory coloured plastic case mounted on a steel baseplate. It complies with the radiation limits established by the FCC for Class A computing devices. Although this standard states that operation of complying equipment is likely to cause interference in residential areas, I have not encountered problems even with a television in the same room. The Max-80 is 17.5 inches wide and 10 inches deep. The top of the machine is 2 inches off the table top at the front and slopes gently upward [like my Amiga 600] to 3.5 inches at the top of the keyboard. The rear of the case holds a line fuse and all the connectors and switches [sounds familiar]. The internal power supply operates off 110-115 volts AC and is efficient enough so that a fan isn't necessary to keep the electronics cool [computers needed fans back then?]. The entire computer requires only 28 watts. Even after hours of continous operation, the case is never warm to the touch. The reset button is safely located at the rear of the machine. Except for an optional 64K bank of memory, the Max-80 is complete as it comes out of the box. There are no extra boards for disk interfaces, serial I/O, or video electronics. As a result, the machines original cost is its only cost. The machine is available with LDOS 5.1 and CP/M 2.2; much of the available [TRS-80] Model I and Model III software are supported as is 8-bit CP/M software. This combination of operating systems provides access to a larger software base than that of most competing machines. - CPU: Z80B @ 5.07 MHz (faster than TRS-80 I, II ,III & 12 and the Softcard Apple) - Realtime clock (years, months, days, hours and seconds, all accessible by software) with internal rechargeable battery - Keyboard features a 10-key numeric pad, 4 programmable function keys and a cursor- control block that includes a clear key. All ASCII keys are supported by auto repeat and the entire keyboard is fully debounced. - RAM supplied by one (or two) banks of 64K each, provided by 8 (or 16) Texas Instruments TMS 4164-20 chips. - Only 1 ROM which contains a small bootstrap loader that disables once the system boots. As a result, the modified LDOS supplied with the system loads the bottom 12K of RAM with the code that resides in ROM on Tandy or LNW [who?] machines. Consequently, currently available self-booting disks don't operate on the Max-80. - Separate gold plated card edges for connecting 5 inch and 8 inch floppy drives (both supporting single and double density, aswell as single and double-sided, disks) and are supported by the built-in controller in both TRS-80 and CP/M modes. A slide switch mounted adjacent to the 5 inch disk connector controls pin 32, permitting it to select drive 4 or, alternatively, to act as the side-select signal when using double-sided drives. Track counts of 35, 40, 77 and 80 are supported on 5 inch disks and the standard 77 tracks on 8 inch disks. - A hard disk interface is also included in the Max-80 and is available on a 50-pin, gold-plated card edge on the rear of the machine. This Shugart Associates Standard Interface (SASI) is designed to be used with an external controller. Both of the computers operating systems are presently configured to use Lobo Systems' Universal Controller and do not support other controllers without modification. - Maximum of 4 drives with LDOS, or 8 drives with CP/M. Since so many disk options are available they have included a DIP (Dual In-line Package) switch is provided on the rear of the case so you can boot from either a 5 inch (or 8 inch) floppy, 5 inch (or 8 inch) hard disk or a 5 inch (or 8 inch) floppy connected via the universal controller. (If you have the extra 64K of memory installed, it's possible to set up a ninth RAM: drive with 1K of directory space and 63K of storage space) - 5 inch disks can be formatted in Lobo's single or double-sided, double density format or in Osbourne, Xerox 820 or Omikron single density, single sided formats - 8 inch disks can be formatted in IBM single sided, single density and double sided, single or double density formats. - Serial I/O is provided from 2 independently programmable RS-232 interfaces (provided by a Z80 SIO chip, rather than a UART chip as in Tandy's machines) accessible through DB-25 connectors on the rear of the case. Either interface supports all standard baud rates up to 19,200 and can be used to drive a serial printer. - Parallel printer output is available via a standard Centronics interface, with a slide switch adjacent to the port which permits grounding or ungrounding pin 27 to adapt to printers (like the Epsom MX-80) that interpret a grounded pin 27 as a request to generate a line feed after each carriage return. - Video output is via a RCA phono jack and drives any monitor that accepts 1 volt composite video from a 75 ohm source and provides 15,750 Hz horizontal and 60Hz vetical sync frequencies. Lobo recommends a monitor bandwidth extending from DC to atleast 12 MHz to obtain good detail in the display, This is especially important in the CP/M mode, where the normal display is 80 characters by 25 lines. You can select a 40 character by 25 line display with a function key. In the TRS-80 mode, the display is a compatible 64 or 32 characters by 16 lines. - Standard TRS-80 Model I graphics are supported by the LDOS operating system - the extended graphics of the [TRS-80[ Model III are not. In the CP/M mode you can display up to 192 user-defined shapes. The first 128 shapes are limited to shapes that can be defined in the top half of a 8x16 pixel rectangle (and in normal use are used to display the ASCII character set). The remaining 64 shapes can be defined in a full 8x16 pixel rectangle. Max-80 with just 64K and CP/M 2.2 - $820 LDOS 5.1 - $69 64K RAM expansion - $95 Amdek Video 300 Green Screen 12" Monitor - $175 Regards, Andrew B aliensrcooluk at yahoo.co.uk

Hi, I'm new...

by aliensrcooluk＠yahoo.co.uk

Hi, I tried to post this last night, but used the wrong address (cctalk at classiccomp.org)! I'm new! I'm Andrew, 26, from the UK and since 2001 have developed a healthy interest in the Amiga after getting an Amiga 600. I won't bore you with it's specs (unless anyone wants me too :) ), but I have a problem in that it's possible a resistor may have become faulty (looooonng story). With all this talk of PCB's etc. I was wondering if anyone here had any advice (or experience) in replacing a resistor (if it's possible)? I use my Amiga for fun and for developing my own games (via AMOS BASIC and then compiling them) and music (thanks to Teijo Kinnunens Octamed 5). I also have recently started becoming interested in the TRS-80. I currently have 30 issues of 80 Microcomputing (#20 to #50) which I bought off a guy from Ebay Australia and they are pretty much in mint condition. Great for reading and learning about retro computers (not just the TRS-80) :) Thanks for listening and I hope to learn alot about retro computers in the coming years.

Furthermore, SCO is one of those lovely companies for which headers are a part of the optional development environment, and TCP/IP is another add-on (how do they stay in business whan put against xBSD/Linux? the FUD about IP doesn't work against BSD- been there, done that, adjudicated non-infringing). The best way to get information off of one of these systems is to TAR an archive out to a raw hard disk. Then you can untar it on another UNIX system. UUCP could also work - haven't tried that route.

Not classic, but free: HP-UX

by compoobah＠valleyimplants.com

The bundle does come with a complete development environment (C, C++, SoftBench) on the Apps CDs. No mention of trial, and SoftBench works o.k. Of course, since HP is giving you the developer discount, you should feel obligated to share anything you build :->.

> That would be me. I've been completely consumed for the past three months > putting the Computer History Museum's software collection together. What I > have pdf'ed is at bitsavers.org/pdf/hp/ > > I need to get this stuff back to Joe ASAP. Hi Al, Thanks for the heads-up! And a fanstastic reference site. A clarification regarding the pascal 3.0 / 3.1 / 3.2 software which I'm looking for, it is HP Pascal for HP 9000 Series 200/300 machines. And is anyone able to clarify whether the latest version was 3.5, as queried by Bernd Kopriva in an earlier post? Regards, Peter -- No virus found in this outgoing message.

intel multibus ram documents needed

by jclang＠notms.net

I have a couple of multibus RAM boards I'm looking for jumper info or schematics. There's not much on the boards to identify the model the first board: 62KB dram board multibus 1 16 bit data path the only marking (other than "INTEL") is PWA142779-006 The second board: 256KB dram board multibus 1 16 bit data path the original marking was PWA143156-045 this is struck out with black marker and the number 133292-002 is written over it. (this board may have been upgraded some time in its life) I suspect both boards were part of an Intel MDS. (there was an ICE in the pile that I wasn't able to save) joe lang

imsai 8080 power switch

A loaded transformer isn't an inductive load, it's mostly the same type of load as what is loading the secondary. Zero crossing is the best place to turn on nearly any load, it may not be the best place to turn off some loads but for on it is usually best. If you turn on an inductive load at the zero crossing zero current will flow. There will be no surge. Unless there is a serious fault, and even then it is unlikely, you won't saturate the core of a transformer regardless of how you switch it on. Lee.
