FS: Symbolics 3650 LISP machine

by mrfusion＠uranium.vaxpower.org

so, im thinning the herd some more, and have had to make a tough decision... to keep the lispm or not... and ive decided i need to find it a new home. so, i have for sale, a Symbolics 3650 Lisp Machine. While some of the gear has been given away, the lispm is one i paid a good bit of money for (i actually bought it surplus from Symbolics!) and so this one is for sale. It'll go on ebay soon if there's no interest here. The machine is fully operational , has a 750 MB disk, 4 megawords (36 bit word size) of memory, and has Genera 8.3 (the latest version as of 2001) installed. Some pictures of it can be found at the url listed on the bottom.. just scroll about 2/3 of the way down. I'm asking $800.00. It's in Pittsburgh, PA, btw. happy hacking, Isildur http://www.vaxpower.org/~isildur/computers.html

PDP-7

by toresbe＠ifi.uio.no

Hello all! I'm restoring a PDP-7 machine to functional condition, pictures at http://tore.nortia.no. Anyone here ever worked at DEC while this was happening? Anyone know anything about the PDP-7? I saw a post regarding a still-functional PDP-7 running a Van der Graaff posted July 2002, but the poster doesn't reply to my mail. Know where it was? -Tore "Pluribus unum, infinitiv thesaurus.

New toy - HP 1611A Opt A65

by stuart＠stuartsjohnsonfamily.net

I just received a HP 1611A Logic Analyzer with Option A65 (6502 uP) and I am looking for 1) documentation, and 2) how to make the cable from the pod to the uP socket. My internet search (Google) turned up - zilch. If anyone has the operations manual and/or the service manual or knows where they might exist online, I would appreciate you posting the address or emailing it to me. If someone has the manuals and would loan them for scanning, that would be helpful too. Ditto for the manuals for sale. I'm sure the cable from the pod to the uP socket is quite simple, but as I haven't seen one in 15+ years, could someone describe it for me? If someone has one for sale, that would be good too. I am also interested in acquiring options for this unit: HP #01611-62107 Microprocessor Logic Probe for 8080A, 9080, and Similar Chips HP #10260A Logic Analysis Plug-In Module and HP #01611 62105 Microprocessor Logic Probe for Z-80A and Similar Chips HP #01611-62101 External 8 Bit Probes HP #1540-0325 Accessory Large Carry Case. or other items not listed.

VAX vs. Alpha for OpenVMS

by healyzh＠aracnet.com

OK, a bit of an odd question here, but I'm wondering what people think as I'm used to a PWS 433au. A co-worker of mine just bought a VAXstation 4000/90 and a DEC 3000/400. She wants to use one of them as a Mail Server running OpenVMS. The VAX looks to have 104MB, the Alpha looks to only have 96MB. Any idea on which would work best for her? Part of what has me concerned is the lack of RAM on the Alpha. If she uses the VAX, it will probably end up running V7.3, if the Alpha probably V7.2-1H1. DECwindows won't be loaded, which will help get the Alpha down to a better memory footprint. Oh, she'll probably also want to run a Webserver on the system so that the mail can be accessed via the web. Zane -- -- | Zane H.

These have a binary to 1-of-10 decoder made out of photoresistors and neon bulbs (!) in the black box. It's not a HV supply like he guessed. It should be possible to make a clock but he'll have to modify some of them to reset before the usual cycle of 0-9. Resetting at 23:59:59 is probably harder and would take some kind of external logic. They already have a feedback to make them reset after 9 instead of counting to 15 - it just has to be modified. On the other hand if he wants to make a clock, nixies are cheap and it might be better to just leave the counter modules as-is and use some logic more suited to counting the time (which is not 10-based). I'm sorry I don't have a schematic. It should be easy to trace out - it's just four flip-flops and a feedback line for reset.

Commercial steel wool is oil-coated to prevent it rusting. Philip described his as going black, which I expect will be the result of the oil carbonising in the hot air stream. The result will be a tough coating of carbon that will prevent oxidation. A similar idea is sometimes used for steel tools -- heat until it develops a blue oxide layer then plunge into oil. The resulting blue colour is fairly pretty, and rust-resistant. -- Pete Peter Turnbull Network Manager University of York

Homemade Hot Air Soldering Tool

by erd_6502＠yahoo.com

Was it here that I was reading about turning a RadioShack Desoldering Iron into an SMT hot air tool? The basic gist is that you remove the rubber bulb, plug in an aquarium pump on a long-enough air hose, and pack some (stainless) steel wool inside the de-soldering nozzle. The pump provides continuous air over the steel wool which facilitates heat transfer to get the air temp up to something useful. I have used $800 commercial versions of this at work with great effect. I have done some initial digging and have come up with the following: RS De-soldering Tool - $10 new Weller De-soldering Attachment - in junk box Aquarium Pump - $7 - $70 new So... I can use one of my Wellers as the heat source, or I can drop $10 for a dedicated (non-temp-controlled) unit. What I'm hung up on is that I have no idea what capacity pump to buy. The $70 pump is somewhat large, but is adjustable. The $7 pump is too small to enclose a golf ball. There are numerous models in-between, including several with dual taps. So... has anyone here had any experience building such things? If I didn't read about it here, I'm baffled where else I would have run across the info. Thanks, -ethan The New Yahoo! Search - Faster.

Bulk Erasing Cassette Media

by cb＠mythtech.net

Ugh... this tape drive is going to be the death of me! Now that I have a small supply of Maxell tapes for my TEAC MT-2ST/N50 cassette drive (thanks Don!!!), I've run into the next problem. All the tapes are reported as "content unknown", and claim to be 60 MB (the drive claims to do 150 or 160 depending on which info you pay attention to). Neither of those are too big of a surprise as the tapes are used, and logically have data that Retrospect on the Mac can't understand, and may very well have been written to last with an earlier version of the drive (different models support different MB's, and from what I can tell, the tapes are all interchangable for writing at max MB, and upwards readable so you can read a lower MB tape on a higher MB drive) However, all the tapes ALSO report that they are locked. Regardless of how I set the write protect slide, the tape is still seen as locked. Which means I can't erase or write to the tapes. I opened the drive, and the write protect sense switch appears to be physically functional. I have not yet broken down the drive enough to see if it is electronically functional (although about the best I can do is test for switch continuity in the open and closed positions). I'm wondering, is it possible they are seen as locked because of the data on them? Is there a way to software lock the tapes? Or maybe the locked is a side effect of having been last written at a lower MB (some kind of a safety to keep you from screwing up the data with a higher MB drive). If so, is it safe to bulk erase the tapes to wipe the data, or will I destroy some kind of a control track as well and render the tape useless? I know some kinds of media should not be bulk erased for just that reason. I would just give it a go, but since I only have 10 tapes, and these have proven a bit tough to locate, I don't want to destroy a tape without at least consulting the resident group of experts.

Hi Ben I didn't build it, I just made it work. A real pain, since I didn't have any schematics and it had several problems. There are a couple of pictures at: http://www.rdrop.com/~jimw/jcgm-vcfiv.shtml Look down 8 rows. The first 2 pictures in that row are my Nicolet machine ( It has 12Kx20 core ). It is all ttl/dtl, thought. Notice the front panel switch position. It is 7600 octal, the boot vector in core. One of the interesting things is the ALU. It has a 5 input port adder. One can select from, ALU, ALU*, MEM, MEM* and "one" to add together. One can do a lot with this combination. Anyway, back on the original subject, there are also some interesting minimal instruction processors described out there. As I recall, there was one that had only 4 operations. SUBtract was one of them ( considered more important than an ADD ). I've been toying with making a single bit relay based computer. My intent is to make the main memory bank using reed relays with a magnet to bias them. The idea is that the external magnet has just enough effect that if the reed relay is closed, it stays that way. If it is opened it stays open. One would arrange these relays in an array with small ceramic magnets, north and south poles alternating so that there is no cumulative bias. Writing to the reeds, coil in opposite directions causes it to open or close. Data is handled by a shift register so that the bus is always 1 bit wide. It'll be slow but what the heck. To make things a little more complicated, I expect to use 3 phase clocking. With this, I can use overlapped clocks, without racing. Dwight

by mvg1＠earthlink.net

Free (you pay shipping), or trash by end of May: Found a box of 53 used quarter-inch cartridge tapes hiding in my home. These are LOW CAPACITY tapes (450 feet/137.2 meters), almost all are 3M brand DC 300XL/P tapes, some few are other brands. All are used (contents unknown, apparently backups). Storage boxes are generally present, in mostly good condition (some cracked), but have been written on with marker. All have been stored inside. You are welcome to as many as you like; tell me your shipping address and I'll tell you shipping costs (USPS Parcel Post (calculated via www.usps.com)). Shipping originates from zip 63132. No cost for packing and shipping, only USPS out-of-pocket costs. I fully expect a thundering silence; I just hate pitching them without at least asking. Mark Grieshaber mvg1(a)earthlink.net

Found that VS-85..

by jim＠smithy.com

Finally found a Wang VS-85. Had to take it apart to get it in the house! I'll be putting up some information and pictures on my web site soon. The power supply had been removed, so I hacked together some cables and used a power supply from something else. It has 1MB main memory, an I/O controller for 16 serial (Wang coax-connected devices), four SMD disk ports, a tape drive controller, and a couple of other unknown I/O controllers. The most interesting part: A CE manual, describing the CPU architecture, theory, and lots of other useful stuff, along with complete schematics for the whole system, and most of the I/O controllers. This machine is 32-bit, with an instruction set similar to the IBM 370. The CPU consists of a ton of TTL chips, an ALU made of 74181's, and an 8KB writable control store. The microcode for the CPU resides on a 5 1/4" floppy disk. The floppy disk drive in the CPU cabinet can only load microcode, you can't use it to store data. Each I/O controller has its own CPU (or several). The old ones have a couple of 74181's and EPROMS with a control program, the newer ones use Z80's, and have RAM only, the control program gets loaded to them when you IPL the system. It's about the size of a clothes dryer. The standard power is 120vac, but the hacked-in power supply is 220vac. Draws about 4 amps @ 220vac. -- Jim Donoghue Smithy Co. (734) 913-6700

HP nixie tube module information needed

by uban＠ubanproductions.com

Hello, Probably my best find at the recent Hamvention in Dayton OH was a stack of nixie tube modules made by HP. In retrospect, I wish that I had purchased the whole box of them, but I hopefully have enough to at least make a clock. I have two variations on the modules, the part numbers are: HP 05212-6016 series 648 HP 05212-6003 series 415 They both use Borroughs B422 nixie tubes and look like they may have an integrated HV supply of some sort. Here are a couple of pics for reference: http://www.ubanproductions.com/Images/nixie1.jpg http://www.ubanproductions.com/Images/nixie2.jpg I would appreciate if anyone can tell me what HP (or other) instruments may have used these modules. I would also like to find a schematic of the module if possible. Thanks! --tom

Preserving ancient media

by Paul.HILLS＠landisgyr.com

Thanks for that. I tried simply zipping up a .WAV file created by the program I mentioned and it compressed from 544kb down to 3.4kb. The original data file was 409 bytes, so although the result is 8 times bigger than the data file, storage is not too much of a problem. At this compression ratio (or rather expansion I suppose), a CD could store 80Mb of original computer data - more than was probably ever written for some of those computers!. paul -----Original Message----- From: ard(a)p850ug1.demon.co.uk [mailto:ard@p850ug1.demon.co.uk] Sent: 20 May 2003 00:26 To: cctalk(a)classiccmp.org Subject: Re: Preserving ancient media > That's sort of what I was thinking of.

Some did, many didn't. What's worse is that some manufacturers used a constant time for each bit (so that one state was a single cycle of 1200 Hz, the other was 2 cycles of 2400 Hz, say), but many other manufacturers used a single cycle at each frequency for the 2 states. This means the bit rate is not even constant... > the other way round). How many stop/start & parity bits (and possibly more > control bits) are sent may be computer-specific I guess. However, a reasonable quality digital audio recording of these old tapes might well be enough to preserver them (you could play it back to a real tape, or directly into the home computer). It's not an efficient way to store the data, but it's better than losing it totally. -tony

OTOH, when you throw in the RSX and RT-11 runtimes, it does get a little unusual, but that's part of what makes it appealing to me :^) Zane

OpenVMS software.

3-1/2" Floppy Market Cornered

by cb＠mythtech.net

>I thought you could use 3.5" HD/DD disks in a DS/DD drive just fine. At >worst a piece of tape over the "wrong" hole if necessary. At least with the Mac, this isn't a good idea for long term use. It will sometimes format the disk as DD if you tape over the HD sense hole, but even if it does, you can pretty much count on the disk failing in a very short period of time. I've never had a disk last more than a few read/write sessions. After that, errors start occuring and you can't read or write to it any more. In many of the cases, the disk is usually hosed after this and won't take a format back to HD anymore. I can't say that I've really tried it outside of a Mac, so it might just be a Mac thing that keeps it from working. And despite the fact that some company made a hole puncher to make DD disks into HD disks (I have one), that doesn't seem to work any better on the Mac. In fact, in my findings, it works even worse as it rarely ever even took the HD format in the first place, and when it did, it immediatly starting having R/W errors and was unusable anyway. -chris <http://www.mythtech.net>

Cool Find

by Lee.Davison＠merlincommunications.com

Visiting a charity shop this week I found one of these .. http://www.vintagecalculators.com/html/anita_1011_lsi.html .. an Anita 1011 desktop calculator, 10 digit Nixie display and all for the sum of Two pounds forty seven pence. Apart from the rubber feet having melted into a marshmallow like crusty sludge it's mint condition with the manual and dust cover. Looks very pretty all lit up.

Mathiputer

by Ghena2＠aol.com

<< I just took delivery of a Cybernetic Systems Mathiputer.It's a stupid odd-shaped math toy that quizes you on arithmetic..... >> Hey, i WANT one of those things! In some thirty plus years of teaching special education kids, i have never found anything before or since that has worked as well for getting number facts semi-permanently into a certain subset of smart, but learning disabled, brains! NONE of the newer fancy number facts software can hold a candle.... If i knew how to program, i'd write something for windows that worked precisely like the good ol' Mathiputer! So.... If happens you know where i can get one that is still functional, at a price i can possibly afford on school teacher's wages, PLEASE LET ME KNOW!! Thanks, Ghena Dalby Ghena2(a)aol.com

Current Subscribe Procedure?

by GOOI＠oce.nl

Well, I quickly checked for Outlook. Outlook Express *could* be different as with many other things between Outlook/Outlook Express. To see all headers do the following in Outlook: - open the mail message (not preview, but "full screen") - click "View" from the menu bar - select "Options..." from the list that appears. The "Message Options" dialog box opens. - In the "Message Options" dialog box at the bottom the scroll box shows the "Internet headers:". - Henk. > -----Original Message----- > From: Zane H.

Being a major smart A** I can't resist pointing out the following information in the message headers. Though since you're in a Win98 system I suspect they're probably hidden from you (I read a lot of the messages using 'elm' on Unix so I see most of the headers).
