Panasonic Sr. Partner needs a new home

by vcf＠siconic.com

The Panasonic Sr. Partner is an MS-DOS compatible luggable with a built in printer and and display. Please contact this person directly if you are interested. Reply-to: mlrplast(a)htc.net ---------- Forwarded message ---------- Date: Wed, 15 Nov 2000 11:17:14 -0600 From: CM <mlrplast(a)htc.net> Subject: possible donation I have a Panasonic Senior partner. It was a gift from my sister, who got it from a friend. Since I don't know about 'dos', etc. and can barely use my 'new' computer and being at a total loss as to how to use this thing, I am considering donating it to a good cause. I "asked Jeeves" about obsolete computers and eventually found your site. I would rather NOT have to pay to ship this thing. Is there anyone in the St. Louis, MO area who might be interested in it? Just checking. It works fine and has considerable software with it. Thanks, C.

I've got a bunch of 5.25" full-heigh 2.1gig Seagate differential SCSI hard drives (along with the 19" drive trays, qty. 3, and rack slide rails the trays go on) free for pickup in north Austin.

DG Nova 4

by blergh＠dds.nl

Hello people, I'm currently seeking information on Data General's Nova line of minicomputers. I saved a Nova 4 yesterday, and since I'm unfamiliar with DG hardware I have a few questions. Is the the Nova 4 bus backwards compatible with the bus on the Nova 3 (i.e. can I pull boards from the 4 and put them in the 3) ? When I remove cards from the backplane, do I have to insert something like a "continuity card" ? The system was in a custom "Medtronic" cabinet, and together with the CPU I got a few I/O boxes which might be useless without the medical equipment. I pulled one of the boards from I/O box 1, and I hope somebody can identify it: DMA0 PC BD 207 005-00 C ASSEMBLY 877-121-00 MDA0048-87 (handwritten) CC board, sevice, sys zaak The boards in the I/O boxes look just like the ones used in the CPU, same handles, same bus connector, but they're shorter. Furthermore, I'm looking for a description or picture of the back of the CPU box, since I suspect something is missing on the right side of mine. Last but not least, a description or picture of the top of a Perkin Elmer ST-2222 diskdrive would also be greatly appreciated (is there supposed to be a lid ?). Sincerely, Erik.

Trying again. Help need with rescue.

by dlw＠trailingedge.com

I don't want to throw out any of it. I'd love some OSI stuff. The person offering it up wants people who would preserve it and I told him there were plenty on the list. I've had some people respond about helping pick up and I'm trying to arrange things. When I learn more and if/when we have stuff that people on the list might want I'll post. Thanks to everyone that replied. On a side note, I just received around 400 pounds of TI and Amiga hardware, software and doc. Most of that weight is due to a large collection of TI and Amiga magazines. Now I just have to sort through all of it and make an inventory. It seems everything comes in cycles. It's been slow until recently. :) On 14 Nov 2000, at 15:55, George Rachor wrote: > Don't throw out the OSI equipment! > > I don't have the room to help with this but make sure the OSI stuff > doesn't get tossed! > > George Rachor ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

Intro and Nixies

by ajp166＠bellatlantic.net

From: THETechnoid(a)home.com <THETechnoid(a)home.com> >Aren't the NIXIES you mention vaccume tubes with letters or numbers in >them? Used as displays WAY back when? > >Ed Kirby at Computer Parts Barn has a few of those he might sell. Nixies are not vacuum tubes they are filled with neon or neon/argon gasses for the characteristic neon orange glow. There were VF displays, those were litterally Vacuum tubes (valves) where the plate surfaces were phosphor coated and had a filiment and even a grid for control use. These were an offspring from the earlier magic Eye tubes (tuning eyes and bars). these were more appealing as the high voltages needed were in the 18-60 volt range at very low current and their structures also allowed for easy multiplexing into larger arrays.

pdp11/14, NASA, and Pioneer 10

by jim＠calico.litterbox.com

I was reading Invention and Technology magazine today about how Pioneer 10 is STILL functional, but one of the problems they're having keeping it going looking for the heliopause is the pdp11/14 that compiles its commands is getting very hard to keep alive. I don't do old minis, but it seemed to me this was the kind of thing folks here would love to involve their classic iron in.

value of Apple ///, also CBM P500 stuff

by agraham＠ccat.co.uk

Hi folks, After my crash in the summer my solicitors want to know how much it would cost to replace the Apple /// that received a mashed keyboard (physically broken veroboard along with several tracks). A quick ebay search reveals none currently for sale, and I must admit I've only ever seen 2 offered in the UK and they're the 2 I've got! Any clues as to the current replacement value? Obviously this has to include availability and it must work......similarly for the HP Apollo 9000-400 I'm claiming for. As for the P500 I've been told that there were both European AND US versions, the european one being massively more common than the US one. Since none of the websites I know about that mention the P500 include this info does anyone know how accurate it is? I'm getting another one this weekend to add to the collection as well as a boxed MOS KIM-1 and heavily expanded PET8296 :o)) More news on that lot when it arrives. -- Adrian Graham MCSE/ASE/MCP C CAT Limited Gubbins: http://www.ccat.co.uk (work) <http://www.snakebiteandblack.co.uk> (home) <http://www.binarydinosaurs.co.uk> (The Online Computer Museum) 0/0

Can't boot Bondwell B310+

by b.layer＠vikingelectronics.com

Hi, I have a Bondwell B310+ laptop, the hard drive of which has been wiped clean. The machine resists my every effort to boot it from floppy. I have tried 1.44MB and 720K floppies, with DOS 7.0, 6.22 & 3.3. All attempts produce the same results - either "Non-Sytem disk or disk error" or "Disk I/O error". The floppy's spin & seek behaviors seem fine. I have seen a number of posts online, with the exact same issue on the B310+, and there has been mention of a special boot floppy for this machine. I need any help on information, thanks in advance. If you have a boot disk image, please send it and let me know what special format (if any) the image uses.

Intro and Nixies

by jforbes＠primenet.com

Hi, I've been lurking for a week or so. I'm not a computer guy per se...my brothers got that! but I pick up some stuff. I have basement full of mostly mid 80s 8088 boxes, as well as some Kaypro cp/m machines, and some newer wintel machines. See: http://www.primenet.com/~jforbes/ for an (incomplete) overview. As for Nixies and home brew computer displays, one of my brothers is into Nixie tubes, so I've kept a lookout for them...and recently found an old piece of Danish test equipment with 5 nixies in it, which was destined to go to the landfill. It had been sitting outside, and was not in very good condition...but I pulled the display board out, and it seems to be usefull (see link above for a pic). If you want to drive Nixies from a TTL BCD signal, just score some 74141 type devices, they were made for the task! Also....I was digging thru some old stuff while cleaning in the basement, and found a Motorola 6802, 1982 vintage. I wonder if it's usefull? Jim Forbes in Arizona

Sun Sparc2 offered to me. What should I check for?

by claudew＠sprint.ca

Hi I am being offered a Sun Sparc2 locally. These are not really common where I live...I could always get one from ebay...still Seems my collection of "home pc's" will now be extended to Sun systems...I am not familliar with these really... Rather then search the net for hours, I taught I might find an "expert" here to give me straight answers... Unit comes with keyboard, mouse, 64M ram 2G HD. What a decent price for this? They seem to go for anything from $10 to $40 on epay... What kinda monitor will this need? What should I check for? What kinda performance does this thing offer if I wanna try it out? (compared to...) It will run Linux right? Claude

RX02 drive emulation (was RE: Lisa Profile Drive emulation on a PC)

by ajp166＠bellatlantic.net

From: Clint Wolff (VAX collector) <vaxman(a)uswest.net> >out in software. I work with enough brainy people I should be >able to get a PLL and data separator working under matlab... Thats the easy part. RX02 was a dual density system with the data being recorded in double density (MFM) and the rest of the marks in FM (single density). A PLL that can make that switch is better than good. Hint it was done as DSP in hardware TTL and 2901. Rx01/02 based system (DEC or clone) only read a fixed set of formats and that's it. True RX01 and 02 systems the drive box was semi smart and the cabled to the system where the card there was only a bus interface. I have both real RX02 (also reads RX01) and also CPM crates with "normal" 8" floppies. >a 10-pin ribbon cable coming out of it. I also have a dual RX02 that >came with an 11/23. Can the interface card be used in a uVAX? Yes but software support may not be there depending on version of OS used. >Before I sell the CP/M 68K system, I want to make sure I keep all the >DEC formatted floppies that belong to the '780.

Old tandy 1000 keyboard 8 pin din pinout?

From: Dwight Elvey <elvey(a)hal.com> >Hi > Which 80186? These came in a lot of flavors. Every letter >following meant a change in pinouts or some feature inside. >All of the 80186's had some amount of select line decoding. >This along made them completely incompatible, pin wise, with >any of the more standard '86 family parts. >Dwight Ah no, the 80186 and the 80188 were the only versions though the PACKAGE was different with plastic and ceramic plus PLCC and other varients. The only other version was the CMOS varients same part in cmos. That it up held by my Intel 1987 embedded controller Handbook. The incompatability with other family of '86 parts was not from package but from differences like the DMA controller and interrupt controller are not the same as the more common 8237 and 8259A that are used with 8088/6 and the 286 family. That created the incompatability based on programming model and addresses used. FYI: the 186 approach was a better implementation than PC style. Allison

80186 Nimbus

by optimus＠canit.se

On the subject of whether the Research Machines 80186 based computer was called PC1 or Nimbus, I managed to dig out an old issue of Practical Computing (March 1985) where the machine is reviewed. It is actually called RM Nimbus, but is available in two models - PC1 and PC2. Thus, both parties were right. It features 3.5" floppy drives, an 8910 three-voice sound chip (Is this the same as the YM2149?) as well as an Oki digitised voice chip, and has dedicated graphics chips which are quite speedy. -- En ligne avec Thor 2.6.

Pretty amazing stuff. Thanks. Yes, that is the same sort of thing. One difference (perhaps an improvement) in the Genrad digit-display modules is that the grain-of-wheat bulbs are just slid into tubes in the back of the module -- their contacts poke out the back of the module and mate up with spring-loaded contacts in the display chassis. Also, the modules slide out from the front of the unit, so replacing the bulbs is fairly straightforward and can be done without soldering. -Frank McConnell

Just a quick additonal classiccomp-related Electra/P3 note

by xds_sigma7＠hotmail.com

I just thought that the group might find it interesting to know that the P-3 Orion carries, as part of the electronics suite, a Data General Nova 3. Nifty, isn't it? Just in case anyone thinks I'm talking about the avionics, I'll go ahead and say that I mean the Nova 3 is part of the ASW suite.. Oh yeah, ASW = Anti-Submarine Warfare, which is the Orion's primary function, though it also serves as an all-purpose patrol aircraft, and it can even carry out anti-ship missions (it has underwing hardpoints for Harpoon cruise missles). At least I seem to remember that it was Harpoons it could carry, at any rate, it is capable of carrying some sort of missiles ;p Will J _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

system/36 awefully quiet...

by mcguire＠neurotica.com

Sounds like 220v 2-phase. Two hots and one neutral/ground. If its marked 20A, I believe the connector is probably an L6-20 twist-lok. Not difficult to wire up in most US homes. My computer room is running from two APC Matrix 5000 5kva UPSs, which have 220v inputs and 110/220v outputs. I ran two 30A 220V (L6-30 twist-lok) circuits from the two outer poles on my breaker panel to power the UPSs, and everything (be it 110v like the regular Alphas/Suns/SGIs and such or 220v for the Crays) runs from the UPSs. Having the equipment run from dedicated 220v 2-pole breakers is very, very nice. Definitely worth the trouble. -Dave McGuire On October 31, Merle K.

RML LINK 480Z with network connection

by celigne＠tinyworld.co.uk

I've just acquired another 480Z, but this one powers up with the words "Z-NET Firmware Vers 1.1q", and there is a BNC connector on the back. Would I be right in thinking that this is a Research Machines proprietary network? The other good news is that I've got a working 5.25" disk drive with it, and a single disk, for an educational Viking game. (I thought that the machine dated from 1984, but perhaps I'm a thousand years out). Instead of typing "R" to run BASIC from ROM, you can type "B", and it boots CP/M >from disk, loads another version of BASIC, and then runs the game. I can then exit the game and use CP/M, which is something I've not done for 15 years. Oddly enough, the 480Z talks to the disk drive through the serial port. The disk drive also contains another serial port, which I've yet to experiment with. As with my other 480Z, the high resolution graphics only displays in black and white on a television. I've still not made up a monitor cable, despite asking for (and getting) the TTL RGB pinouts many months ago, so I don't know whether it will produce a colour display at all.

Computer LCD projection panels

by mrbill＠mrbill.net

I picked up a Sharp QA-25 computer LCD projection panel from a local junk shop today. The glass/"optics" look just fine (no scratches, just needs to be Windexed), but I have no manual or power supply or data cables for this. I remember using one about 10 years ago when in school, but I dont remember if this uses EGA or CGA inputs (has a 9-pin D-shell data input). I'm guessing probably CGA; anybody know specifics on the data cable? Think I can hook it via straight-9pin-cable to the CGA out port on the back of a laptop and fire it up? (fortunately I can use a standard generic wall-wart power supply; it has the specs and connector diagram on the side of the unit). Now, off to the office surplus store to get an overhead projector for $10.... Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

old 7-segment displays

by JRichardson＠softwright.co.uk

Hi all, (not sure if I have posting access here - guess I'll find out soon enough!) The recent messages about displays have made me recall a bunch of little devices I have stashed in a box someplace... They're mounted on a board in such a way that they look like they're the display panel for an ancient fuel pump, but I could be wrong. There's two sizes, one about an inch high and the other about 3/4", and some of them are double-digit within the same housing. These things are glass, with a black background and silver segments - there's a lot of discolourment on some of them around the segments on the rear of the glass facing. Pins come out of the rear of the devices. Any ideas what these could be? Some sort of mercury vapour or something? It'd be nice to hook them up - I bought them from a car boot sale a few years ago and never got around to doing anything with them. I can probably work out which pins drive what, but have no idea what sort of voltage these things will need (I'll try to remember and get whatever text info there is on the PCB itself - think it was just a bunch of part numbers, but there might be something meaningful to someone if the board didn't just come from something as mundane as a fuel pump) cheers Jules

"ajp166" <ajp166(a)bellatlantic.net> wrote: > You can but nixies are a pita to drive. Of era lamping would be > bulb per bit. cheaper too. Hmm. I saw an interesting display device at a friend's the other day, in some sort of Genrad whatsit that he was getting ready to scrap. (He's keeping the display digits though.) Each digit is a box with a bunch of tiny incandescent bulbs mounted in the back; each bulb illuminates one layer of plastic at the front; these layers are stacked and each has a digit (or other symbol, e.g. decimal point) etched in it (as a bunch of etched dots). There's a diagram on the side of each digit-box that indicates which bulb illuminates which digit or symbol. Anybody got any ideas about this thing? His speculation is that somebody didn't want to pay for nixies (but he's amazed at what these things must have cost to build in comparison), mine is that they wanted something nicer than a column of digits 0-9 with a bulb behind each. -Frank McConnell

Lisa 2/10 Dates

by fuzznut＠resspc134-189.canberra.edu.au

Hi All, I've just started following this list again after a 6month absence. Anyway, I recently picked up a very nice Lisa 2/10 in working order with all its docs/manuals/disks etc. I simply followed the advice of people on this list to "put an ad in the paper", and after a couple of goes I was rewarded with this machine. I have it currently up and running with Lisa 7/7 v3.1 and Lisa Pascal Workshop. I have one strange thing about it tho, it is a 2/10 which I thought were relased in early 1984, however the case has a manufactured date of "4282", is this a 1982 date or something else? Also, was there any 3rd party software for the Lisa available, and is there still any out there? Oh yeah, it also has a AST RAMstak card, giving it 2mb. Regards, Karl

Indeed it wasdeparture. the V20/30 was an attempt to wrest the 8086 market from intel... a few years in court NEC won as it was indeed much different inside. What's bizzare is NEC also was licensed for and made the 8088/6 fully compatable part too. Anywho the differnces are enough that dropin is not done. Allison

Need to sell out?

by aclark＠envirolink.org

As the years roll by, more and more Apple /// and ][ users/collectors are selling their holdings due to a lack of time and space. If you are in this situation, I want to help. I am a young Apple collector who will provide a good home for your treasures. I readily buy Apple hardware in good condition. Don't let uncertainty on the value of your hardware hold you back! I buy often enough to know what it is worth. Ask for what you want for it. I may suggest that you charge me more. (If you have working equipment that is in excellent cosmetic condition, you _will_ get top dollar for it.) If you live in or near Pennsylvania, I may be able to pick up at your home to save you the bother of shipping. I will consider long-haul pick up trips for exceptional hardware. Help me build my collection, I'll help you clean out some needed storage space. Regards, Arthur Clark

Pal and NTSC

It is a straight-thru switch. The main issue here is the colour encoding. If you could get a usable display >from your Atari in 50Hz mode, you will get a usable display from the Famicom. If your VGA/TV converter only understands NTSC colour encoding, the picture will be in black-and-white. (Assuming that it works with a 50Hz/625 line picture.) You can get analogue NTSC-to-PAL colour standard converters, which only change the colour encoding, not the number of lines per field, for about US$80 if I remember rightly; I believe MCM Electronics sell something like that. Short of making/buying a PAL-to-RGB decoder, that is what you want and would give better results more expensive standards converters. Depending on exactly which console you have, it may be possible to modify it to give true NTSC output; some Famicom clone consoles have this capability, but a real one does not. Oh, if your Famicom only has RF output, you'll need a TV tuner that is compatible with its signal. [Contact me by email if you need more help, and give a description of the console.] -- Mark

There's a diagram on the >side of each digit-box that indicates which bulb illuminates which >digit or symbol. These were common in the 60s. Driving nixies has one problem you need a transistor that can handle at least 60-80V, early transistors werent cheap (those that could). Also you needed high voltage (170-220Vdc) for nixies, plus resistors for current limiting all adding up to to a lot of space power and heat. Transistors that could switch 100ma@6V were common and cheap so the same diplay idea was used. There were other reasons with respect to readability and diplay color as well. Another config that was used is a 7segment where each segment was a wedge of plastic forming the bar and a lamp (or later led) behind it. These preceded the LED based 7 segment at low cost. For those that don't know there were also filliment based 7segment displays (have a bunch) for the early growing display market. They were aimed at the problem of good leds at that time being expensive and not terribly bright. My first freq counter has four of these and still works 27 years later. >Anybody got any ideas about this thing? His speculation is that >somebody didn't want to pay for nixies (but he's amazed at what these >things must have cost to build in comparison), mine is that they >wanted something nicer than a column of digits 0-9 with a bulb behind >each.

passive backplane wanted

by azog＠azog.org

One day I found someone throwing out an "Industrial Computer Source" SBC (look at http://www.icsadvent.com/ and search for "sb586t"). There was a passive backplane as well, but it was a 2 PCI 6 ISA slot backplane, which is kinda large. PICMG is the designation for the form factor. I searched, and found at least one company that sells a 2/1 slot backplane, but they're industrial, and wouldn't sell a single quantity. My hopes was to build a nice tiny box out of it. Given the form factor, it would be roughly the size of a shoebox. So, does anyone have a source for backplanes? I don't need any ISA slots, and would rather have just two PCI slots. I could take a dremmel to the existing backplane, but I would end up cutting off the headers for the power switch, etc, due to the way the backplane is constructed.
