Hi all I just found 3 packages of Masstor data cartridges. They are cylindrical about 2 1/2 inches in diameter, about 4 inches long and look to be covered with some sort of oxide surface. They are hollow and have a kind of snap in connector on one end. I have examined the Web and the only references I find are for large mass storage devices for supercomputer and particle accelerator labs. I seem to remember, from some movie, some sort of robot arm storage device that picked cylindrical cartridges out of a honeycomb structure and inserted them in to a reader/writer. Very large storage, about 360 GB, late 80's early 90's time frame. Any information would be approciated Mike mmcfadden(a)cmh.edu

Card identification required.

by netsurfer_x1＠hotmail.com

I have just recently picked up a Tandy Color Computer 3 (which I have nicknamed "Spectrum") at a local thrift store. After opening it up, I found an internal card plugged into some connectors on the system board. The card does not look to be a Tandy add-on. The unknown board bears a name of "DISTO CANADA" & has 16 Mitsubishi M5M4256P chips on it. What is this card? Is it some sort of internal RAM expander or internal disk controller card? Any help would be more than welcome. ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.

Or to ban > free speech just because some idiots don't know eht hey say ? I wholeheartedly support this MAPS RBL, et al, blocking. The simple fact-of-the-matter is, open relays are wrong. They are the result of bad administration and serve no purpose other than to provide spammers the mechanism to operate anonymously. Performing this SPAM blocking not only protects the subscribers of a list from the resultant abuse of mismanaged mail servers, it forces legitimate operators of mail systems to properly administrate their machines. If a subscriber finds themselves receiving reject responses to their submissions, they should receive within the reject reason a reference to the URL for the service which has listed them or their mail relay as a SPAM source or Open Relay. The submitter should either correct their local problem, or notify their ISP or mail server administration of the issue. The SPAM/anti-relay database servers all provide for quick and fair consideration for removal from these lists once the blocking issue is resolved. To say that this will "ban free speech" is totally unwarranted. There is absolutely no reason for an open relay EXCEPT to facilitate spam. The InterNet is much too sophisticated for any claim of necessity for such a facility. Anonymity is not a factor in Free Speech. I applaud this action, and encourage everyone with the ability to have their mail agents interract with the MAPS RBL, and other databases, to fully support and integrate this spam-blocking service.

Nice article in Wired 8.03 on "Retroactivism"

by mgregory＠vantageresearch.com

There's a good article in this month's Wired on what they call "retroactivism" - people using trailing edge computers in preference to the latest Wintel box - for all the reasons we're familiar with: stability, well-understood O/Ses, nostalgia, etc. The VCF gets some mention, and several classiccompers (notably Allison Parent) are quoted. A good, balanced article that doesn't have the faintly mocking tone of that other recent article (in the magazine with Rosie the Robot on the cover). Cheers, Mark.

I found an HP150 (model 45851A?)--how do I make it work?

by fmc＠reanimators.org

There are two styles of 150. One is the 150A/B, and in rough outline it looks something like a 120 or 2382 terminal but does have different casework from those. These models have a 9-inch display screen; I think the only differences between A and B are the ROM'd firmware and accompanying MS-DOS version (and I do recall that it was possible to upgrade a 150A to a 150B with a firmware-and-software swap) but someone else may know better. Then there is the 150-II aka 150C aka Touchscreen II. It's in a boxy enclosure with tiltable 12" display screen. I think the 2392 terminal might have similar styling (2393 does not, it uses the 37531A pale green-screen monitor with the terminal logic in a separate box). After HP introduced the Vectra (PC-compatible, at least more so than the 150) and 150 sales dropped off, and ran out of 2647F terminals, HP started shipping 150-IIs as consoles for /68 and /70 systems. (Maybe /64s too.) Unfortunately I have no idea what kind of terminals HP sell these days. 700/9x? I don't think they ever made a 150 that looks like those, although they did make some monochrome VGA monitors in a similarly-styled case. -Frank McConnell

Intel Microprocessor and Peripheral Handbook, vol.2, 1987. 68000 Assembly Language Programming, Kane/Hawkins/Leventhal, 1981. Motorola MC68020 User's Manual, 1984. I also grabbed a couple of genuine Apple mousepads and a Macally clone keyboard for $2. They also had an HP terminal keyboard, but no terminal. I'm keeping my eyes open... Cheers, Aaron

Stuff to trade/stuff I'm looking for

I can't remember whether the terminal would come up without the keyboard (but I think so), and I don't really know for sure what is inside a 2649 though I think it's not too different from a 2641/2645/2648, meaning an 8080 processor...unfortunately my memory's far enough gone that I don't really remember what's inside a 2645 either beyond a bunch of boards. But those boards would be things like a processor card (which I think also has ROM and about 1KB of RAM), a keyboard interface, a datacomm interface, one or more cards for the display, and zero or more memory cards. Some of the cards (but not the memory) would also be joined at their tops by a sort of "frontplane" interconnect board. That said, there's limited interchangeability between 264X terminal keyboards. Once upon a time I swapped keyboards and keyboard interface cards between a 2640B and 2645A just to see if I could, and it mostly worked. Of course, there was the matter that the 2640B keyboard didn't have all the same keys, and its baud rate switch wasn't labeled above 2400. So far as the 3000's concerned, you could also use 262x (for x>1; 2621 will work for character mode but will not support VPLUS block-mode applications), 2382 (which is nice and small but has a 9" display), 239x, or 700/9x terminals. Or an HP150, which pretends to be a 2623A graphics terminal when it's not being a personal computer. BTW, I think you mentioned passing up some HP terminal keyboards, and you might want to stop that, as the keyboards have a habit of becoming detached from the rest of the terminal on their way through the surplus food chain. Once you start thinking about network configuration with NMMGR, a 264X terminal can be a problem as later versions of NMMGR were made to use the terminal's function key display area for some screens, and 264X terminals don't have a function key display area. I have no idea why NMMGR was changed; as near as I can tell it was mostly gratuitous on HP's part and NMMGR will still function correctly, you just have to know which function keys correspond to which functions on those screens. (Guess who was still using a 2645 as the system console and only hardwired terminal on his 3000/58. Fortunately, I did know which buttons to push.) On the other hand, the 2645 will run Space Invaders, and I wouldn't be surprised to find that the 2649 would too. > An HD for my HP3000 that will fit in the bottom rack space.

A 7958 is about (a little larger than, I think) 100MB and will work and fit in a 3000/37 cabinet. 7958B is faster than 7958A if it matters. I think bigger numbers (e.g. 7959 and 796x) are larger capacities. -Frank McConnell

OT: Question about GIF optimisation

by CLASSICCMP＠trailing-edge.com

>Is there any tool known to optimize GIF files in size ? >It hapened that I just changed some GIFs and without >changeing the content the files did grow. After some >research I found that the editor I used adds some headers >(or whatever) structures, increasing the file size. >Not a big increase, but if a 900 Byte picture grows >to 1100 I'd like to remove the overhead. The best way is to convert the GIF into a "portable" bitmap (i.e. nothing but the bits), then back into a GIF again. I've been doing this for a decade with a package called NetPBM: NetPBM, GRAPHICS, Suite of graphic image format manipulation & conversion pgms Enhanced portable bitmap toolkit. The PBMPLUS toolkit allows conversions between image files of different format. By means of using common intermediate formats, only 2 * N conversion filters are required to support N distinct formats, instead of the N**2 which would be required to convert directly between any one format and any other. The package also includes simple tools for manipulating portable bitmaps. As of the last release I built (early 90's), it was supposedly available at: * wuarchive.wustl.edu (128.252.135.4), directory /graphics/graphics/packages/NetPBM * ikaros.fysik4.kth.se (130.237.35.2), directory /pub/netpbm. * ftp.informatik.uni-oldenburg.de (134.106.1.9). This site also carries binaries for the Amiga. * peipa.essex.ac.uk (155.245.115.161), directory ipa/src/manip * ftp.rahul.net (192.160.13.1), directory /pub/davidsen/source * ftp.cs.ubc.ca, directory /ftp/archive/netpbm What *I* like about NetPBM is that it's a command-line tool, not a "point-and-drool" graphics tool. This means that when I have a few thousand images to convert (as I just did yesterday) that I can do them all with a command script. I especially like it for things like auto-cropping and twiddling colormaps to make backgrounds be "transparent". -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

By the time of the Touchscreen II, lots of us who had deployed 150A/Bs had concluded that while the 150 wasn't that bad, touch screens were not all that they were cracked up to be. You had to take a hand off the keyboard and reach up and touch the screen, and if you had to do this a lot it resulted in a sort of fatigue that was called "gorilla arm", and there were usually ways to do what you wanted from the keyboard (either a function key or tab around some and then press a function key or Enter). So most users didn't bother with it after the novelty wore off. So when it became an extra-cost option we really couldn't see paying for it. Besides, who wants a bunch of fingertip-sized smudges on the screen? -Frank McConnell

Archive Viper Data Cartridge Drive - Available for cost of shippi ng

by jdykstra＠nortelnetworks.com

I've got an Archive "Viper" 150 MB. data cartridge drive with SCSI interface, model 2150S, available to the first responder for the cost of shipping. The drive worked the last time I used it (several years ago), but there's no warranty. The belt, heads and capstan are unworn and appear in good condition. This is the drive only--no enclosure or power supply. If you want them, I also have seven data cartridges. Althrough they physically fit this drive, they may not all be accepted by the drive's firmware--I have a half memory that certain drives only worked with certain cartridges. If you want this drive and the cartridges, email me your address, desired method of shipping, and whether you want the cartridges. If I don't hear anything by Wednesday, it goes up on eBay. ---- John Dykstra jdykstra(a)nortelnetworks.com Principal Software Architect voice: +1 651 415-1604 Nortel Networks fax: +1 612 932-8549

Two VMS software tapes available

by af-list＠wfi-inc.com

I finally built a rack for my 9track tapes and went through them all. In addition to what looks like an entire software distribution for my (still dead) Cadnetix system, I found two VMS tapes, available to anyone interested: XDS-11 Base Package Signetics' Amaze Rev.C Binary (must be an *ancient* version of this, marked 1985) Cheers, Aaron

TI DS990/1

by aek＠spies.com

there is a dissassembly of the boot rom for the 990/4 up at www.spies.com/aek/orphan.html now, along with one for the 990/12. If you have a way to dump the boot proms, it would be interesting to see how similar they were. If you have a way to take pictures of the boards, I'd be curious to see what the I/O cards look like, esp the floppy controller board.

TI DS990/1

by jbdigriz＠dragonsweb.org

Today's acqisition here is a TI DS990 Model 1 Intelligent Terminal. This designation appears to be a complete misnomer as it is in fact a full microcomputer. The case appears to be laid up in fiberglass from the same mold as a TI 820 KSR, and the logic bus has 86 pins, which I recall >from other terminals of the late '70s, but it has a 3 Mhz TMS9900 processor (nice BIG white ceramic JDL part with gold pins), 64K of ram (4116's, plus parity), a TMS9900 based I/O controller board, 2 asych serial cards, floppy disk controller, and a VDU controller. Going by the configuration table on the back of the case there were other options available as well, including "GPH", which I am wondering whether might be some sort of bit-mapped graphics display. The backplane has a total of 12 slots, 7 occupied. There are what appear to be 3 serial connectors on the back of the case, but they do not connect directly to the serial cards. They go through the bus apparently. I've never had my hands on an 820, but I don't think they're this elaborate, and the 911 VDT's I have certainly aren't. Nice hefty modular 200W linear power supply with its own bus, too. This particular unit has seen some rough handling at some point, and is missing a few keycaps, but it is clean, and powers up. There's a nice raster on the screen, but no cursor. Apparently it must boot off a disk. There's a 25 pin connector on the back of the case which must be for a cable to a FD800/1000 dual 8" drive (which I don't have yet). The "IDLE" and "EXEC" lights on what amounts to a minimal front panel on the keyboard light up, but that's it. No "ERR", anyway. Somebody please correct me if I'm wrong, so I can track down the problem. In actual use, from what I was told, it was probably hooked up by modem to Tymshare, the predecessor of Tymnet, and thence to a central facility. It has lttle bezels on the front shoulders of the case that identify it as a Tymshare Travel Business System BS2000. As an aside, I did a little searching, and apparently MCI/Worldcom is still running Tymnet, now on rackmount Sparc-based nodes rather than the earlier PDP-10's.and M68K's (I preferred Telenet for X.25; they were always a year or two ahead on dial-in speeds where I was.) Anyway, if anyone has manuals or software, in particular a bootable system disk, for this machine, I'm all ears. Likewise, if anyone has any questions about it, I'll do my best to answer them. jbdigriz -- ---------------------------------------------------------------- DragonsWeb Labs - Custom R&D, Software, & Hardware ---------------------------------------------------------------- Tagline for Tuesday, February 22, 2000 If rabbits feet are so lucky, what happened to the rabbit? ---------------------------------------------------------------- James B.

Actually, germanium diodes, e.g. 1N43A, 1N270, etc, have a forward voltage on the order of 0.32 volts. There are numerous SCHOTTKY diodes with considerably lower forward voltage.

Information still needed for Infotron IF/65 Development System II for 65XX microprocessors and CUBIT EPROM Programming board - AIM-65 or KIM ?

by whdawson＠mlynk.com

Hello to all, I'm still looking for information for these items: Firstly, an Infotron IF/65 Development System II. It appears to connect via RS-232 to a dumb terminal for its output of such things as address and data, and perhaps input of some parameters such as uP clock rate; baud rate is selectable from a thumbwheel. This system also appears to have the capability of single stepping the program contained in the device in the ZIF. It has a 28 pin ZIF socket for the targets EPROM/PROM/ROM. There is a standard ribbon cable that connects to a pod, and the pod has a braided ribbon cable that terminates at a 40 pin dip header, most likely to attach to the target in place of the uP. Trap conditions are selectable via four 0 to F thumbwheels, and conditions to be triggered on can be selected as memory data read, memory data written, and/or op-code. Any information would be greatly appreciated, a source of a manual or instructions for use would be fantastic. This equipment can be viewed at http://www.wpic.com/whdawson/Pics/infotron.gif and secondly: A CUBIT EPROM programming board for the AIM-65. It is not an RM65 board, the connector will plug right onto the expansion connector on an AIM, but can also be attached with an appropriate 1-to-1 ribbon cable. Here is the description: Measures 4-7/16 (4.4375)inches wide by 6-1/2 (6.5) inches long, including edge connector, lengthwise insertion. 44 pin gold plated edge connector with a 44 pin socket mounted immediately behind and parallel to the edge connector, on the component side of the PCB. 24 pin ZIF connector in the upper LH corner, viewing with the edge connector facing me (all descriptions below assume this position). 10 position DIP switch immediately to the right of the ZIF socket (no labeling), and another 10 position dip switch about halfway up the RHS, labeled 1 to 7 and B, C, D (probably address selection since one row of pins is all tied common and most of the pins on the other side of it go to a 74LS154). One LED, immediately to the right of the first 10 position DIP switch mentioned above, at the edge of the board. Two trimpots about center of the far edge of the board, to the right of the LED. Two jumper blocks, one with 2 pins, labeled W1, and one with 3 pins, labeled RO and RA. Two Toshiba 24 pin TMM2016P-1 RAMs left of center in second row of DIPs on the board. One 2516-45 EPROM to the left of the RAMS, with a label on top "6517A". On the solder side the only markings (in etch) are CUBIT INC, 1981 and the numbers 10362 and 6583. Most of the date codes on the ICs are between 8037 and 8203. There is no other model number, manufacturer, or other ID marking on this board. This programmer can be viewed at http://www.wpic.com/whdawson/Pics/cubit.jpg Thanks, Bill whdawson(a)mlynk.com

Germanium diodes have the least amount of voltage drop while conducting (about .06 volts I think) and a popular one that should be readily available is the 1N34 or 1N34A. The reason that diodes seem to act funny on an ohmmeter is because of the fwd voltage drop while conducting. The silicon diodes that you probably got at radio shack have a fwd drop of more than .5 volts and will appear as a high resistance to your meter even though they are conducting.

Diode help... HELP!

by jeff.kaneko＠juno.com

Bill: You should test your diodes with an OHM Meter that has a high enough test voltage to overcome the barrier potential of approx 700mV for a silicon, and about 300mV for a germanium device. What sort of application are you looking use it for? For high current/voltage applications, silicon is pretty much your only choice, as they can be made with very high PRV (peak reverse voltage), and higher power rating. For small-signal use, germanium diodes work best; they have low barrier potential and lower 'ON' resistance (sounds like this is what you want). Used to be, the glass diodes RS used to sell were a mixture of both types. You can tell the difference with a DMM that has a 'diode' test range; the DMM will put enough voltage across the device to foreward bias it (turn it 'on') and display the apparent resistance of the device. Germanuim devices will have a lower apparent resistance. Another way would be to apply a (low) voltage across the device with a resistor in series, and measure the voltage across the device. Of course, all diodes have some reverse leakage current, and all diodes exhibit this 'barrier potential' phenomena; the trick is to find one with a low enough 'on' resistance that will satisfy your requirements. I used to get diodes from RS to make crystal sets; in those days, I found the best ones by wiring it into the set to test it!

Hmm...keep in mind that all semiconductor diodes exhibit a forward voltage drop...0.3v for germanium and 0.7v for silicon diodes. If your multimeter isn't using more than that forward voltage drop to measure that "conducting-mode" resistance, you won't get anywhere with that measurement method. -Dave McGuire

I have noticed that the earlier Sams are available now on CD-ROM. Don't remember if they are direct from Howard Sams or through third-party. I'm lucky, as there are complete libraries of Photofacts available at both the downtown KC library and in Independence. Even had them in Tacoma, WA so check your local library for availability.
