UK/US power question

I'm pretty sure it can; the Compact uses a standard SMPSU in the disk box. There should be a 110/220 link on it. To open it up, you need to remove the front and rear trims. These are clipped into the side trims, but also have two (or three?) bumps on top and bottom edges which fit into small slots in the metal case. They're a bit fiddly, and often very stiff the first time, but they will come off without tools. Then you can remove the side trims, and if I remember correctly, there are a few obvious screws to remove before sliding the cover off. (Caveat: it's a long time since I've taken a Compact or an Acorn Filestore (same case) apart). -- Pete Peter Turnbull Dept. of Computer Science University of York

RG-71/U 90 Ohm Cables.... can anyone use 'em

by badger＠vbe.com

I came upon a supply of brand new Consolidated RG-71/U 90 Ohm coaxial jumper cables. They are 3 feet long and are terminated with a Kings PL-259 on one end and a Kings BNC on the other. I don't know what they were intended for .... although the connectors are very common RF items 90 Ohm impedance isn't. Someone told me that RG-71/U might have been used in the computer industry....... I don't know ???... but they are high quality factory cables. I'm not sure but I think they were used with some type of scientific equipment or sensor ???? If you can use these cables let me know ...... reimburse my shipping costs and you can have them. Mailing should be between $3.20 and $6.00......... Regards, Mike Melland

forklift rental in San Jose, CA?

by eric＠brouhaha.com

[more about the computer rescue mentioned in my last message] Unloading in Milpitas, CA will be even more fun since we don't have a loading dock at this end, the ramp isn't wide enough, and the truck companies won't rent trucks with lift gates for one-way moves. Apparently they don't think that people move large heavy awkward items one-way. It's a shame since I know from personal experience that a VAX-11/780 (or 785) will just fit on the lift gate of Budget's 15-foot trucks. (For safety, I recommend having at least three people to stabilize a VAX while a fourth operates the lift. However, in an amazing display of sheer stupidity, a friend and I unloaded a 785 by ourselves.) Has anyone had experience with forklift rental? I did a web search and turned up *zero* hits. From a different rescue operation, it is known that a forklift is a excellent way to move a PDP-11/60, which is almost as big as the 11/780. However, that time there was a lumber yard across the street that was willing to send the forklift and operator over to help; this time there's no lumber yard nearby. :-( Eric

Vax 8350 offered to me -- worth getting it?

by claudew＠sprint.ca

Hi I am being offered this computer. I think it's 3 large modules. I have large collection of micros from the 197x-198x but, I know almost nothing about vax'es... I would we prepared not to keep it or donate/trade parts or whole...I have no real space to keep this for a long time... It would be in Montreal, Canada. Is it worth the hassle of picking it up? What should I check for? My wish list : TRS80 III (I and IV too), NExT, older CP/M systems... Thanks Claude

THose interrupts and IO lines offere more than most minimal z80 systems without Zilog peripherals. The 8085 is often forgotten despite being a decent chip. Allison

No question the z80 has many more bits than 6502, 8080, 8085, 9900, and a pot load more.

I tried to limit it to the programmer accessable. If we add temp registers and whole knows what in the state or microcode portion of the machine it surely would grow more.

Lisa WEIRD!

by jlewczyk＠his.com

If the connections are only to the video board, then the "magic switch" is simply a way of adjusting the "height" of the display. In one position, the video is full height, with the standard Lisa rectangular pixels. In the other position, the video is vertically squashed to produce square pixels. Its pretty low-tech. The device probably has adjustable resistors somewhere on a small circuit board in order to tweak the display for each position of the switch. If you pull it all off, you have just the standard Lisa (full height) display. I think that it would be pretty straight forward to homebrew one of them. The real Apple-supplied modification was more involved and produced a full height, square pixel display. It included a transformer which modified the screen height, a new video rom (which controlled generation of video sync signals and the Lisa serial #), and new boot roms. John jlewczyk(a)his.com -----Original Message----- From: owner-classiccmp(a)classiccmp.org [mailto:owner-classiccmp@classiccmp.org]On Behalf Of Marion Bates Sent: Saturday, November 04, 2000 2:52 PM To: classiccmp(a)classiccmp.org Subject: Lisa WEIRD! Okay, so after my post I went and fiddled some more and lo and behold, after a few more power cycles it booted perfectly from the hard disk. It's running MacWorks Plus some version or other with Mac System 6.0.3. The hard disk sounds like it's full of sand (yikes) but otherwise it seems to be fine. :) This is where it gets bizarre. I took the top lid off to get at the video adjustment pots and managed to eliminate the vertical jumping etc. so the screen is pretty much back to normal operation. But inside, on that same board just below those adjustments, I saw two or three sets of jumper wires, the kind with the little spring-loaded L-clip at the end. One end of one of them is clipped to R1 right near the top of the board, and I can't see where the other end is without really gutting the machine, which I'm not ready to do just yet. Another jumper has one end connected to a leg of R21 and then it disappears inside. It also looks like there's a small alligator clip connected to a heat sink and leading off somewhere else. So it looks like someone went in there and jumped some connections, then closed it all back up and left it that way. I'm afraid to touch them. Maybe this is related to the mystery switch (see my earlier post). Strange... ?

PT SOL-20 question

I've been watching the Altair, IMSAI, and SOL-20 listings on eBay lately, more out of curiosity to see what they go for than anything else, but noticed something odd about a SOL-20 image. In the listing, the picture definately showed a SOL-20, but instead of the normal front panel showing 'SOL Terminal Computer' in both white and yellow lettering, this machine has a single 'Interactive Computer' in whie stylized 'computer font' across the front. Is this an OEM version of the SOL-20 sold under another name?

A while back I said I passed on an cmos ASIC project that was going to use 8088 (actually 80186 core) as a embedded app. the client insisted on it and planned to inegrate 32-64k of rom and at least 4-16k of ram with it.

VAX 4000/60

by azog＠azog.org

I've been lurking here for about a month now. A friend of mine told me there were a lot of DECheads here, so I signed up. I've been puttering around with big iron for about a few years, but I don't have anything left (had two VAX 730's and several PDP-11's - an 11/34, 11/73 and what I think was either an 11/04 or an 11/03... I'm sorta regretting getting rid of any of them... I'd like to get back into hacking Unibuss stuff someday) Anyways, I recently got a VAXstation 4000/60 from e-bay, for what I considered to be a nice price. Works fine. Had VMS 5.5-2 on it, but I got the hobbyist license and VAX/VMS 7.2 CD from montagar (good deal!). It only has 24mb of RAM - 8mb built in, and four 4mb chips, leaving two slots open. Unfortunately, the best I can do on that setup would be 32mb RAM. I know the machine can do 104mb (96mb in chips, I guess that would be six 16mb chips), but I'm not sure of the type of memory used. It also has two RZ25's, which are a bit tight. What limitations do I have on drives that can be installed? I'm not using the frame buffer. My intention even before I received it was to run a serial console. But I think it might be fun to run a graphical display. Have no idea what type of frame buffer is installed, except that it has an odd sub-D connector with three mini-BNCs inside. What's the specs on the monitor that can be connected? Can I get an an adapter cable to connect it to my PC monitor?

Heathkit EC-1 For Sale to Highest Offer

by badger＠vbe.com

Now that I have an idea of the EC-1's general value from members of the list ...so I don't get screwed selling it blind ...and, as I learned from my faux pas in stating I was selling it on eBay... In order to allow members of this forum to have a chance to purchase this computer prior to my listing it on eBay, here it is. If you are interested here are my terms: 1. Offers are accepted via email effective 2000 hrs UTC, November 3, 2000 until 2000 hrs UTC November 6, 2000 ONLY 2. Minimum Offer accepted is $350 3. Buyer pays all actual shipping costs, insurance and any import duty or customs fees. EC-1 ships on receipt of payment 4. Payment to be by certified funds (cashier's check or money order) and must be received within seven days of end of offer. Payment may also be made with a credit card via PayPal. 5. EC-1 is sold "as-is" with no warrantee or guarantee I will try to assay the general condition of the computer as accurately as possible. There are no dents or dings. There are a some small scratches. The mesh case is dark green in color. The pots were stiff and two were frozen but were able to be freed up using Caig Labs DeOxit and seem to work fine. There are chips out of the plastic screw slots on two of the the balance pots but they still work fine and it's not noticeable unless you specifically look at them. The tubes test ok and the chassis appears clean and in good order. I can find no obvious faults electrically. The computer powers up.... both filament and high voltage. The meter works and I was able to check the B+ voltage (right on the money) and balance all the amplifiers at all 3 working voltages (100,10 and 1 VDC). It comes with the original operators manual and three of the resistor/capacitor plug ins. No other plug ins, leads or cables are included. All the knobs and switches are original and they are in very good condition. I have tested the unit only this far and all seems well but it is sold "AS-IS" with no warrantee due to it's age and my inability to test it's operation further. A picture is available at http://www.vbe.com/~badger/bc/ec1.jpg or http://www.vbe.com/~badger/bc/ec1a.jpg If you need more general information, have something you want me to check or e-mail pictures let me know.

PDP-10 Emulator (was: Re: MULTICS Installation, Halifax)

by xds_sigma7＠hotmail.com

LOL, I essential gave away a complete, operational 2065 (KL-10) complete with manuals, software, 5 or 6 RP06's, and a pair of TU78's, simply because I could no longer afford to go rescue it after making expensive car repairs... So I shudder to think what that would bring.. And I want to make the promise that I will never, ever, be caught dead selling any minis or mainframes or whatnot on any auction site... Sure, I've sold some stuff to DEC resellers, but that was just 3rd party crud.. I'm not saying that I don't think its right for these machines to have a value, I'm only saying I personally would not feel right about selling things I have mostly accquired for free..

IBM 5160 saved from the trash.

by ncherry＠home.net

I recently found an IBM 5160 in the trash, it has no keyboard (but I have a spare). It's almost all original! It has 256K on the motherboard, an AST Clock/Serial/384K RAM board (I think it has a game port too). It has the 6845 full length Black & White/Parallel board, a Hayes full length 1200B modem card (Z8 processor), a Xebec hard drive interface card, an internal/external floppy card, the 360K floppy and a Seagate ST-412 (Noisy). I'll try to recover the data off the hard disk, I have no idea how I'm going to deal with the drive issue (I may have an 8 bit IDE card and small drive). I am really tempted to put CP/M-86 on here. I've never used that OS before and it would be more interesting than PC-DOS 2.0/2.11. I haven't completed a full check out of the machine yet but I have enough spare boards that I should be able to bring this up. I even have a spare IBM PC (not XT) MB w/cassette interface. :-) -- Linux Home Automation Neil Cherry ncherry(a)home.net http://members.home.net/ncherry (Text only) http://meltingpot.fortunecity.com/lightsey/52 (Graphics) http://linuxha.sourceforge.net/ (SourceForge)

DECsystem 5400 and NetBSD?????

by mcguire＠neurotica.com

On November 3, Matt Thomas wrote: > Almost anything can be coerced into running NetBSD. :) Ok, Matt. :) You've just uttered the perfect lead-in for what I've been planning to say here for a few days now: I've got a big beefy pmax machine available...a DECsystem 5810. It's in a chassis very similar (identical?) to that of a VAX 6000, with similar power requirements. It has one processor (third digit in the model number) and a LOT (I don't remember how much exactly) of RAM. It has a large XMI backplane plus a BI bus. There are two or three XMI-based SDI controllers, in addition to a plain old KDB50 in the BI bus. There are no disks with the system, but if you're starving for SDI disks I can throw in a couple of RA90s. It has a TK70 also. There are other goodies in the BI bus...if anyone *really* wants me to I'll go out to the warehouse and look, but that will take some effort. The machine is very clean and in near perfect physical and cosmetic condition. It ran fine about two years ago when it was last powered up. I paid real $$$ for it 2.5 years ago, but I'm willing to let it go for a case of Dr. Pepper to a person who can convince me that they won't scrap it. It will need to be picked up in Laurel, Maryland, which is right off of Route 95 between Washington DC and Baltimore. There is a forklift available at the pickup point, and I can get a few guys together to help heft it, but after that you're on your own. This is a really cool machine and I'd like to see it go to a good home. I realize it's big and a pain to move, but I do hope that anyone so inclined will give it some thought. -Dave McGuire

SB180 disks should read using standard PC FDC and the correct driver. The problem is they did some weird sector layout but, the SB180 does use a PC compatable controller (765 core). I can read my SB180 disks on the Kaypro using 96tpi drives. It may be the disks you have are 48 tpi or they can be 96tpi (user option). I've migrated mine to 3.5" drives. > I stuck out.

You would not be ending up with GE hardware. While the Level 68 (6180) system Honeywell built carried over some features from the GE635/645, it had quite a bit of new stuff that wasn't in the 645. For example, rings were implemented in software in the GE645 version of Multics. The Honeywell 6180 put them in hardware. Additionally, this is not a Honeywell 6180 being offered, but a DPS-8/M. If you contact Mr. Renshaw, he may be able to answer the question about a set of coldstart tapes for the machine. If not, Perigon Systems (the "last" Multics) would be able to supply them. The trick is, for how much? regards, -dq

IBM P70

by jhellige＠earthlink.net

I found a rather interesting machine today at a local thrift store. It is an IBM PS/2 Model P70. Normally I don't pick up IBM PC's or clones, but this has the following: - luggable, roughly the size of a large breifcase - 80386 running at 20mhz - red gas-plasma VGA display - one 16-bit MCA and one 32-bit MCA expansion slot - 120meg IBM ESDI hard disk - 4meg RAM - parallel, serial, PS/2 mouse, VGA, and unknown HDI-30 connector on the rear. Unfortunately, it lacks it's keyboard, which isn't connected by way of the standard PS/2 connector. It won't boot past the memory test due to the lack of keyboard and it gives me POST error codes of 301, 162 and 163 on the screen, as well as beeps twice. Does anyone know what the square 30pin connector on the rear panel is? It reminds me of the HDI-30 SCSI connector found on some Powerbooks. I picked it up because I thought a portable Microchannel machine with a gas-plasma VGA screen was pretty interesting. Not to mention it's the only MCA machine I have.

ZCPR >isn't a GUI. It's nothing like Windozes, it's a MUCH better command line >interface. Well CCP is a user interface as is command.com, changing out command.com for Win3.1 still doesnt change the fact that it's a DOS OS with a GUI instend of Command line. So goes it for CP/M, CCP or ZCPR are only a 2k loadable module that can be replaced with anything.

B&C Microsystems up600a software, anyone?

by ethan_dicks＠yahoo.com

I keep meaning to ask this... I have an ancient B&C Microsystems universal programmer, model UP600a. I'm running version 3.0something of the software. The largest device I can program is half of a 27040 at a a time. At one point in the past, I tried to download the newer personality files from the B&C Microsystems BBS, but the file was corrupt (full of text garbage, as if caused by either a rampant disk overwrite or a disgruntled employee or customer). Does anyone out there happen to have one of these beasts? I'd love newer software that supported newer devices, both memory (EPROM) and logic (PAL/GAL, etc.). Thanks, -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

Nupon LTS-4, terminal server

by ncherry＠home.net

I have a Nupon LTS-4 terminal server and I'm wondering if anyone has software for the beast. I managed to find software for it but the software appears to be for a model with a different serial interface (a newer Cirrus chip, this one has a CL-CD180-10PC-C). The symptom is if I set the buad rate to 9600 it runs at ~7K (or about a 20% error). I'm not really proficient at 386SX disassembly (yet) so I can't find the rate table to adjust them.

FS: Heathkit EC-1

by badger＠vbe.com

I have a Heathkit EC-1 Educational Analog Computer with original manual I'd like to sell. The computer is in unknown functional condition (I don't know if it works right or not) but it looks pretty good. I'd guess I'd have to sell it as unworking. All the parts are there but some of the knobs are "stiff". This EC-1 was in storage since the 1970's ...... it was with some electronic test equipment I purchased at a surplus sale at a college. If you have an idea of it's worth .... either to a collector or as a parts unit please email me at badger(a)vbe.com Thanks, Mike Melland, W9WIS (Oshkosh,WI)

Also it could boot in as little as 4k of ram and run basic in 24k. Allison

ultrix disktab entry for an RF73?

by thompson＠mail.athenet.net

Greetings I have an elderly version of ultrix (4.2A) which knows nothing of disks of mind boggling capacity such as the two gigabyte RF73. Does anyone have a later version of Ultrix with the dimensions of this disk specified in the /etc/disktab file? (p.s. has anyone else noticed that Altavista seems to be lamed deliberately or otherwise so that Linux or Netscape clients can no longer search properly? I have noticed this for a couple of weeks...I go into work and use Internet Extorter on NT and everything is fine.) Thanks in advance Paul

Cadnetix

by jjackson＠salsa-digital.com

OK. I've been quiet long enough, I think. <grin> Now it is time to ask a question. I have an old Cadnetix 50000S workstation. It still works - sortuv. I would like to find a replacement board for the ailing one (graphics), or locate technical manuals on this beastie. What is a Cadnetix 50000S? It is a CAD workstation that performs Schematic Capture, PCB Layouts, runs Berkeley unix (I think it's Berkeley), uses a 68020 processor, and can still run rings around many Windows CAD software packages... ok, just barely. <grin> What I'd _really_ like is to find one of the Sun-2 Cadnetix platforms. (I think it was a Sun-2 - it's been a while folks.) Now, these puppies - they could really scream! Anyway, I saw a bit on the 50000S platforms a while back - was just wondering if anyone might still have one and want to swap something or other. I know where there is a Cadnetix burial ground - it's just that I'd have to pay homage to the groundskeeper. Regards, James Jackson

From: Joe <rigdonj(a)intellistar.net> > I used to think that CP/M was great but I just got a system with ZCPR3 >and it's dynamite! > > Joe To make a point. ZCPRx is CP/M! ZCPR is a replacement for the rather anemic CCP (console command processor) and a few additional utilities. Of ten the BDOS and BIOS are unchanged and that is the core of CP/M. The CCP is user interface. The DOS analog of that would be Windows3.1 is not DOS. See the point! Now ZRDOS or ZSDOS is a totally different codebase and non DRI product that is CP/M compatable and draws form the ZCPRx lineage. Allison

Can anyone give a thumbnail sketch of the differences, keeping in mind that I'm fairly familiar with the 2.2 version? In addition to tweaking & adding stuff to ZCPR2.2, I also adapted someone else's take on implementing resident system extensions (RSXs) under CP/M 2.2/ZCPR, as well as putting together a small library of RSXs that would work with it (as well as CP/M 3).

In fact, a DPS-8 can't run Multics, only the DPS-8/M can (in addition to the 6180 and GE 645). However, Multics could be re-implemented on any architecture that either provides a paged, segmented virtual memory with rings of protection, or, on any architecture fast enough that those features could be emulated. regards, -dq

Hello from a new member

Hello, I found this group while looking for information on an archaic computer system. I have several systems at home that may qualify as 'classic' computers... a Heathkit 6500 computer trainer (I think) with documentation SWTPC 6800 - in storage with a hefty 4k RAM Amiga 1000 Amiga 4000 ...and a few others. I am going home tonight to look at them and see if I might have something of interest for someone else. Intel (360?) Multi-Bus I system used for development... complete with software and manuals. I also have much documentation. I'm a packrat when it comes to User's Manuals. But it is now time to clean out the storage room. <sigh> I have information for those of you with Amiga 4000's for repairing your A3640 CPU boards. This is on my web site. Also - for replacing the capacitors in the Audio section. (This applies to any of the Amiga series. They used polarized caps in a uni-polar output stage of an op-amp.)

Old HP Stuff Available

HP SRMs (pre-Unix - will run HP BASIC) available Some CPUs, some hard drives. All have HPIB ports. Possibly some printers. and HP 340's (diskless) with ethernet, HPIB, serial, & parallel built in. Will run Unix. Your cost on any of these would be shipping plus packing at Mailboxes, Etc., plus $10 per item for us to haul them from the basement, put them in our trailer and tote them to Mailboxes. If you're interested, let me know ASAP, as they go to the scrapper on Monday, 10/30/00 when the company's lease runs out. If you're familiar with HP stuff and want details, please contact me. If you're not familiar, I can't help you much, although I *can* read numbers >from front panels if there's anything in particular you're looking for. Just trying to save some good, old hardware from the shredder. It's located in Lincoln, Nebraska, so if you're within driving distance this weekend, we can probably arrange something to save you shipping and handling.

Using Toshiba XM3301B scsi cdrom on old MACs...help?

by claudew＠sprint.ca

Hi Bought several XM3301B Toshiba CDROM drives very cheap. (I am looking for some caddys by the way...anybody got some they wanna throw out?) Trying to use these on old compact MACs and MAC IIs using Mac OS 7.5.5 Used a driver that sees cdrom drive (icon with scsi id for drive appears on os startup) as soon as iso9660 format cd is inserted, it reports that it cant read the disk, it reports the size of the data used up on disk and asks if I wanna format it or eject it... All support files are in the extensions folder (high sierra, foreign files acces...etc...) I am using a driver that says it supports the xm3301 is the readme file. (something from lacie company...off a www page with older MAC drivers.) I have tried apple generic cdrom support. Does not see the xm3301b. (whats the b for anyways?) I have used a newer Pionner scsi cdrom with pionner driver on the same system with success. The newer pionner drive with same driver/support file does same thing.... This must be something simple I cant see...but I am no MAC OS expert... Thanks for reading Claude

Probably the block size. The older Macs require the blocksize on the CDROM to be set to 512 bytes, as do older Suns and SGIs (newer machines work with normal 2048-byte blocks, and issue a SCSI command to reset the size). To fix this requires some minor surgery on the drive. This works for XM3301 and XM3401, but not XM3601 or later, BTW. I believe it works for XM5401 but I can't be sure about others. On the 3301/3401 PCB, there are two solder pads near the rear right corner. Each looks like two semicircles bridgeed together, and they might be labelled 0 and 1 -- if not, 0 is the one nearest the edge of the PCB. The default setting (for PCs) is for 2048-byte blocks. Cutting the bridge between the two halfs of either or both pads gives you 512-byte blocks; the resulting three possibilities are supposed to be for different systems: open, open Sun bootable open, shorted SGI bootable shorted, open generic 512-byte shorted, shorted normal 2048-byte (default) I've fitted a DIP switch to all my old Toshibas, so I can move them between systems fairly easily. -- Pete Peter Turnbull Dept. of Computer Science University of York

I was attempting to point out the shift in role from being a mainstream general-purpose processor to being one used almost entirely for embedded applications. -Dave McGuire

Free Epson JX-80 Color Printer & Summagraphics graphics tablet for Z100 in Ann Arbor, MI

by whdawson＠mlynk.com

These are free for the cost of shipping from Ann Arbor, MI. Please contact me off list if interested, and I'll supply the owners email address. Bill ? Your computer will do far more than you ever expected it to, and that won't be enough. Pournelle's First Law Dear Bill, Way back in February you put in a bid on my Z100. As you no doubt surmised, you were outbid and the Z100 went to a collector out in California. For your information, the winning bid was $350 and that was just for the computer and monitor. Looking over my basement recently I came across the two other items that were part of my Z100 setup, namely the JX-80 printer and the Summagraphics graphics tablet. These are boxed up in their original cartons, complete with documentation and ready to ship. You didn't get my Z100, but I thought you might want these other beautiful vintage items, still in good working order. You can have them for the cost of UPS shipment. The JX-80, boxed up, weighs about 25 lb. The tablet, boxed up, weighs about 10 lb. I'm in Ann Arbor, Michigan, which is about a 5 hour drive from Washington, PA. (Shipping should be less than $20). If you ever get your hands on a working Z100 I'd be glad to send you my Blokpix software at no charge. I quote here below the text of the description I sent out to you about this equipment. ------------------------------------------------------ Additional hardware supported by Blokpix is a Summagraphics graphics tablet with a 2-button stylus and a 4-button cursor. Attaches to the serial port. The active surface of the tablet is 12" x 12". Also an Epson JX-80 color dot matrix printer, which we used to print out our designs. Attaches to the parallel port. I still have a few unused 4-color ribbons for this printer, but they may well be dried out by now. Such ribbons can be reinked. There are a couple of places that do this kind of reinking. Epson no longer makes the ribbons, but you can still get black ribbons that work on it. These are for MX-80 or FX-80 machines. I'll be glad to throw in a handsome custom-designed lucite printer stand. This is a good workhorse 9-pin printer, still working fine. The most interesting software is that which I wrote myself. I have a graphics program called Blokpix that my wife and I used for years to design repeating designs for the fabric, apparel and wallpaper industries. You can have this. I even wrote a manual for it. I also wrote a demo program that displays graphic designs until you stop it. It can be controlled by writing a script. You can have this program along with the script I wrote for showing off our designs at trade shows. This makes a nice display. ------------------------------------------------------ If you want the lucite stand, that will have to go in a separate box. It would add another dollar or two to the shipping cost. Bill, please let me know soon if you would like these items. If not, they will go to the local recycling center where they will be cannibalized for valuable metals. At least they will not go into the landfill. But I'd much rather see their working lives extended by a caring collector like you. Bob

Pinout signal connector + specs for NEC JC-1216DFA monitor?

by claudew＠sprint.ca

Hi Hate to throw this one in garbage, it's like new. Looking for pinout for signal and specs for a (1985 production date) NEC JC-1216DFA COLOR CHARACTER DISPLAY monitor. Looks like a standard ttl color but its got a 8 pin (2 rows 4 pins with 2 top ones spaced for polarisation with DND stamped on it) connector that I have only seen on old (1970-1980) video camera equipement and such. Never seen this for a computer video signal connector. I looked inside and judging from the chips around the input connector looks like it's ttl color. Did not bother to trace circuit more to figure out pinout. Taught someone would know... Before I throw it out or give it away, I want to know more, see if it can be used in some way for me... Thanks for reading Claude

MULTICS Installation, Halifax

by dhquebbeman＠theestopinalgroup.com

Hello, I've gotten mail from the guy who is supervising the decommisioning of the Canadian DND Multics System at Halifax. Not much new, but it's a little clearer in that all someone needs to do is attend the auction and buy it and bring it home on a truck. At least I doubt any "schools" will bid on this, if they do, they'd have their hands full. -dq ---------------------------------------------------- Douglas, I'm supervising the removal of our MULTICS system here in Halifax. John Macleod has indicated that you were interested in the details. On 13 Nov 2000 we will load the 5 CPU system along with FNP's etc. onto a truck destin for Crown Assets disposal. Crown Assets in turn offers the equipment to school projects then publicly auctions it off. We were planning to cut the serial cables to expedite the removal of several hundred cables under our computer room floor. The drives will be held locally for destruction (Security issues) but replacments could be available from GENTRONICS. If you have any questions let me know. Dave Renshaw MCOIN Support Computer Room / NOC Supervisor CS 02 Voice: 902 - 427-0550 X 2554 or 2540 Fax: 902 - 427-6626 E-mail: D.Renshaw(a)dnd.ca

Timex Sinclair stuff for sale

by kevskvk＠inx.net

I was sent this adress by somone at another comp users group..I hope you can post it or pass it on..and I hope no one is offended I have recently found, while helping my landlady in her warehouse in Brooklyn, the following Timex Sinclair stuff. It all appears to be new, or unused, though many of the boxes are beat up from being moved around in a messy warehouse for years. Some of the boxes are very clean though. (TEN) Timex Sinclair 1500 computers..eight of them complete in (if rather beat up) boxes, two out of box. All of them new..never used. in original wrapping. (TWELVE) Timex Sinclair 1000 computers, Mint, New in unopened boxes. (THREE) Timex Sinclair 2068 Computers, new, out of box..without accessories attached, although I have found some power supplies and cables lying around loose. (TWO) 16K Ram Modules #1016 one in box, one out. Six plastic carrying cases for the 1500's (I think..the are little molded cases that say timex sinclair on them) some assorted TS software on cassette tapes, in original wrapping..(will check titles if interested) A whole lot of Timex 2040 printers, Alphacon 32 printers and cases of printer paper for both. All mint, new in unopened boxes of twelve. A reasonable offer...for anything anyone interested? thanks Kevin Skvorak kevskvk(a)inx.net

Splitting binary files for burning EPROMs...

by ethan_dicks＠yahoo.com

OK... so without taking the time to write a C program to do this for me, I have this binary file that is a memory dump of 256KB saved on a 32-bit machine.. I need to output four files, 64KB each, that are the component bytes of that memory space. I know I can write a program to do this. Are there any handy tools lying around so that I don't have to?

Q-bus cards available.

by Mzthompson＠aol.com

A good while back I hauled home what was the control box of an 8" floppy duplicator. The information of the box: Formaster Corporation 1983 Concourse Drive San Jose, CA 95131 Model 4400 I hauled home only the control box thinking the case might come in handy for some project. Earlier I opened it up and found a card cage full of what I assumed at the time was Q-bus cards. Now with the aid of the Field Guide maintained by Megan, I have identified the main card as a Q-bus LSI-11/2 CPU 16-bit card. I have no need for the cards and thought some might be of use to those on the list. A couple of the cards were made by Formaster, so doubt much demand for proprietary cards, but are included anyway. Cards 1-4 are dual height and 5-7 are quad height. So here is the list: ---------------------------------------- 1) M7270 KD11-HA LSI-11/2 CPU 16-bit Q-bus ---------------------------------------- 2) National Semicondutor Memory Systems card Has 4 rows of 9 4116's, so 64k Numbers on the card: 55110358-003C 980103858-001 REV L ---------------------------------------- 3) Sigma Information Systems This card appears to be a disk controller. It has 4 WDC TR1865PL controller chips on it and there are 4 ten pin header connectors on the card edge. Numbers: Assy 400200 CPX-6-0 ---------------------------------------- 4) Formaster Corporation I would say this is a proprietary card. Only meaningful number 003-30026-01 It has a 50 pin header connector and a 16 pin header connector. ---------------------------------------- 5) Acorn Systems memory card Has 8 rows of 18 4164's, so 1 mb Numbers: Copyright 1981 30019-01 ---------------------------------------- 6) Acorn Interface and ROM card I am guessing on this one. I say interface because has 4 50 pin header connectors and 1 34 pin header connector. IIRC, the 34 pin went to the front panel control board. It also has 4 EPROMS (24 pin) with ID stickers on them (Formaster) ---------------------------------------- 7) Formaster card I would say this is a proprietary card. Only meaningful number 003-29978-01 It has two 50 pin header connectors. ---------------------------------------- If you would like one of these cards, then here is the game plan. 1) Send an email reserving your card(s), first come first served. 2) I will not ask any specific amount for these cards. I will ask that you send something to cover a little of my time and the trip to the post office. I'll leave the amount up to you. Hint: Priority Mail stamps make nice tokens. 3) All cards will be shipped by Priority Mail, one card to a box. So send a $3.20 stamp for each card you want. Your card will be properly packed and mailed back to you. 4) Any cards reserved and no stamp received by October 15th will be 'unreserved' and tossed into the recycle pile.

Right. If all I wanted was four 64KB files that concatenated into the original, I could use split. > and of course, you need to know the "endianness" of the machine > where the dump was generated to see which file corresponds > to which column-slice of the rom. Also true. I'll be guessing because the ROM sockets are not numbered on the board. :-( It's a VAXstation/MicroVAX 2000, if anyone happens to know what the EPROM byte order is. I got an EPROM splitter utility from Don Maslin (thanks, Don!) It appears to be just what I was after.

TCP/IP for AT&T SysV R4 V2.1

by b.layer＠vikingelectronics.com

This is a semi-repeat request. Please excuse the bandwidth. I'm playing with an old machine that has AT&T SysV UNIX Release 4, Ver 2.1. There is no TCP/IP networking package that I can find. Can someone tell me if TCP/IP is available, and from where it may be gotten? The post about the VAX got me interested again...
