Twiggy Find

by jrkeys＠concentric.net

I purchased a plastic bag mixed with new and used 5 1/4 floppy diskettes and inside the middle was one of the famous "Fileware" or Twiggy diskettes with it's sleeve used with the Lisa I. I could not believe my luck as I had just watched one of these go for almost $50 dollars on eBay for just one diskette awhile back. Now I just need to find a twiggy drive or better yet a Lisa I. :-) Yes I went back to the thrift store looking for more disk but no luck. The cost of the package was $1.40 for about 20 diskettes.

We had six Macs and one LaserWriter on the same >floor of a smallish retail establishment, so it wasn't a problem. >I can see networks near the edge of their physical spec falling off >a cliff, though. Yeah, phone net was designed with the idea that you would piggy back it over your existing phone wiring... the theory being that a standard house/business would be wired either all serial (one jack to the next) or in a star (all jacks coming back to a central punch block). Following this assumption, it was specifically designed to work over the unused pair (being yellow/black in standard station wiring). All PhoneNet REALLY cares about is having two wires from one box to either the next box, or to a central hub. It need not be twisted pair, and it need not be the yellow/black pair. Although, if you choose to use a different pair, either you need to make sure you wire it to the correct pins on the jack (and thus fake a y/b) or you will have to cut a custom wired flat cord as the boxes all expect the wires to be the outer two wires in an RJ-11. But there is nothing stopping you from using unused pairs in Ethernet and just use a custom flat cord (or break them out into their own jack). The single biggest problem with Phone net that I ran into was it was VERY picky over the wiring being correct. Unlike phones, you could not safely reverse pairs in a serial setup. Also, the fact that it expects there to be either serial wiring, or star wiring falls thru in most phone lines. And even depending on the unused pairs wasn't a surefire idea. In every Phone net system I installed, I was forced to do some degree of rewiring, or correcting the wiring. POTS phones are very forgiving to poor wiring, and many telco installers use that as an excuse to be lazy. In almost all POTS phone setups you will find some degree of "non spec", things like unused pairs not being connected, reversing pairs, mixing star and serial wiring, tapping mid line into a drop to extend for a new jack. Tapping was DEATH to phone net, it was the single worst thing you could do, as it caused things like ghosting (items showing up after they have been removed, or showing up more than once on the network), and random dropouts of networked devices. It also proved hard to track, as you almost had to physically trace every wire, looking for a tap. But all things considered, phone net was a much more econimical way of wiring a localtalk network. True localtalk cables were very expensive compared to cheap 2 pair phone cable, so even with rewiring, it still worked out to be the less expensive way to go. Even today, phone net works as a nice quick and dirty network when all you want is printer sharing. I keep a 25ft retractable cord and phonenet connectors connected to a Localtalk to Ethernet bridge. It lets me connect old Macs to the network (or my Newton) on the fly, and I can set it up anywhere in my office. When I am done, I just unhook the phonenet box, and let go, the retractable cord rewinds and pulls the box back to my hub shelf, where it hangs waiting for my next use. -chris <http://www.mythtech.net>

Although I would not be willing to part with it (thus why I think I still have it), I CAN open it and send some digital pics of the chips. Maybe even draw out some schematics. I would guess that based on its age, there is nothing fancy in there. Probably a simple eeprom or something for storing your stats, and everything else was probably random gates (fighting, spinning, whathaveyou). As far as "emulation" goes, I would think you could just write it from the ground up following the rules of the game. Although, it wouldn't be a true emulation, it would make it playable (and you could do it networked EASY... now THAT would be a cool internet based game!) -chris <http://www.mythtech.net>

(ISTR that you can use the > unused pair in the cable for LocalTalk, but I haven't yet tried it). That's true, you can run all sorts of things over Cat5 "structured wiring", in fact that's the point of structured wiring. 10baseT uses two pairs (pins 1+2, 3+6), the phone uses the centre pair (pins 4+5). ISDN uses all four pairs. Serial lines use either the middle pairs (for Tx/Rx) or all four (DTR/DSR, Tx, Rx, RTS/CTS) if they follow the DEC (and other) system. Some use the same pairs as Ethernet (which means a crossover cable for Ethernet also works as a null-modem for Tx/Rx on serial lines). 100baseTX uses the same pairs as 10baseT. You're not supposed to run a phone line (pins 4+5) on the same cable as an Ethernet (pins 1+2, 3+6); it breaks the spec. However, you'll normally get away with it with 10baseT, and it *may* work for 100baseTX over short distances. It certainly won't work for 100baseT4 (does anybody still have any of that?) or 1000baseTX (Gigabit) because they use all four pairs. Nevertheless, you can buy little boxes which are essentially a Y-piece for phone+10baseT -- you need one at each end of the cable. They consist of a small box with two RJ45 sockets and a short Cat 5 lead ending in an RJ45 plug. You can also get similar boxes to combine/separate two 10baseT signals (they move the second signal from pins 1+2 and 3+6 onto 4+5 and 7+8) and ones to simply double up the sockets (pin 1 to pin 1 to pin 1; ... ; pin 8 to pin 8 to pin 8) which are sometimes used for ISDN. For some reason they tend to be different prices, and all overpriced (over here they cost ?8 - ?15, though you can make one for about ?3 including the cost of the box to put the PCB in). I'd be wary of running Localtalk over a cable carying a phone or Ethernet signal. Again, it might work, but it will probably generate interference which might be hard to track down -- I write from experience[1]. Better to use one cable for one service at a time. The real reason for using different pairs for different services is partly serendipity, and partly to avoid damage if you plug the wrong device into a cable which is already connected to something incompatible at the other end. In my workshop and study I have quite a lot of Cat5 (actually Cat5e, the Cat5 standard is officially obsolete) which I use for 10baseT, 100baseTX, serial lines, ISDN, a phone line, and even the audio to the speakers. I'm about to add a couple of Econet adapters, and I'll probably use it for some LocalTalk (PhoneTalk) when I get round to sorting out the non-Ethernet Macs. [1] More than one bad experience, but exemplified by the occasion when I had to make a trip to Northern Ireland with a couple of technical staff >from Acorn to visit some schools who had networking problems. The school staff insisted everything was done to the standard, but it turned out that their erratic network problems were due to putting LocalTalk down the existing network cables. It had worked for a while, but when they extended the networks, both suffered. -- Pete Peter Turnbull Network Manager University of York

Dark Tower Pics

by mythtech＠Mac.com

A few pics of the controller to Dark Tower have been posted. You can find them at <http://www.mythtech.net/darktower>. (Pic #28 is missing, it is the same as 29, just out of focus). The board is about 7" x 3" (17.5cm x 7.5cm) There isn't a whole lot on it. 3 lights down the middle that are socketed, an LED digit display, a pair of LEDs (IR send and recieve, it is used with the picture disc to determine what pictures are facing out), there are a handful of resistors, a few Capacitors, 3 transitors (9112 D 07; 9113 D 05; NP2 3704) a choke coil, 2 diodes, and 3 ICs. The 3 ICs are all Texas Instuments, photos of them are on the web site (I made sure you could read the numbers, but they are upside down right now) The two connector looking things on the very end of the board opposite the LED digit display... are in fact connectors. The white one tied to the motor, speaker, and batteries, and the black one tied to the push button panel for user interaction (the push buttons are a flat 3 x 4 pressure panel connected to the board by a ribbon cable.) That is about it. I will try to draw up some basic schematics later (I'm a little busy at work right now, hopefully I will get to it later this week, or maybe next week). I don't know if I will be able to do any testing of my unit. When I opened it I found batteries had been left it in, and leaked. There is some pretty bad corrosion of the largest IC where the battery acid dripped on it. I am hoping it will still work when I clean it and put it all back together, but there is a chance it has been damaged. Also, the LED digits have suffered some damage (the laminate cover is peeling back >from corrosion) I will post again when I have the schematics done. -chris <http://www.mythtech.net>

New aquisitions: PCjr (minus power supply) and Amstrad PC 6400

by mythtech＠Mac.com

>To make this perfectly clear, I need the external 110VAC to 16.7VAC >part, not the internal AC->DC part. well, it has been a while since I looked at one, but if I understand you, you want the big black external brick that goes between house current and a small round power plug on the PCjr... right? That is what I think I have one or two of still kicking around. The one I was picturing in my mind (and why I was thinking of an odd right angle plug), was a power brick to an old HP Deskwriter... I realized that about an hour ago, when I kicked the HP brick that was sitting on my floor. Now, the problem is, I might have been thinking of the HP brick when I was thinking I might have a PCjr power brick... but I will still look, just to make sure.

Well, I bought a membership and expensed it out to $CURRENT_EMPLOYER, and they pay for the parking too... but generally you'd be right. There is one motherboard seller selling refurbs, clearly marked, and ditto as maybe or maybe not functional. But a few things do carry a warranty, and I see the same faces and company names almost every time (especially the non-hardware guys like Hacker Hut). At least 50% of the vendors are local and have storefront operations. Russ, are you in Fort Knox? I see you mention the area from time to time, we should get together sometime for a pizza at Impellizeri's... -dq

RS6000 7012-320H

>If the internal disk is SCSI, you could attach it to any other system >(for example Linux), and write a utility that goes through the raw >disk looking for 'root:$[^:]*$:0:0:' and replace it with 'root::0:0:\1' Good thought, but it's not quite that easy. As I recall, AIX defaults to the JFS file system. This is an IBM proprietary, journalized filesystem, and would not be trivial to "write a utility" to safely modify it. Standard Linux (or any other Unix, for that matter) will not recognize it. Luckily, there is a Linux port of JFS (http://oss.software.ibm.com/jfs/). I dunno if it will mount a native JFS filesystem from a legacy AIX box, but it should show you what you need to do to get started. Oh, yeah...AIX stores passwords in /etc/security, or somesuch odd directory. Wants to be a TCB, but isn't really a TCB. I liked and respected AIX...but then I didn't pretend it was really Unix. Ken

The more used, the better for me :-) They do tend to be high, new Americans seeking their fortunes... but a few people carry surplus stuff, and it tends to be priced better if it isn't so decript as to be not worth buying (but perhaps worth picking up off the trash pile). I picked up VB 5 Pro a few years back for $50, and VC++ 5 for the same. But one vendor screwed me out of a academic VB package that came with NT; he had it priced for $50, I made the mistake of asking if it was for real, and immediately it became not so. -dq

Since I didn't know the answer I asked someone who was a Philbrick employee from 1949 to 1966. "Hi, Doug: The standard rationale was that the purpose of the spelling was to differentiate between machines that did computing and people who were employed to do so. For example, my wife's roommate, in the early days of her post-college life, had a math degree and was employed at MIT's Whirlwind lab as a "computer", doing computing tasks that were too complex for the digital machines then existing. However, I think that George really invented the term (a) because it was attention-getting, (b) to differentiate his product from the competition, and (c) because he always liked to do things a little differently and more creatively than the next guy." ========================================= Doug Coward @ home in Poulsbo, WA Analog Computer Online Museum and History Center http://www.best.com/~dcoward/analog =========================================

looking for documentation for 1963 minuteman missile computer

by jtinker＠coin.org

Wow, even a users group! This is great. The boards are beautifully done, discrete logic, and dipped in a conformal coating. Each transistor or diode has its own serial number, which I assume provides traceability to quality control. The card cage is cylindrical, and surrounds where the "stabile platform" would go, except they were removed before the computers were surplused, for reasons of secrecy. I heard once that the whole thing cost about $1/2 million, half for the computer and half for the stabile platform. There is a port in the card cage where a telescope on the stabile platform gets to look out at something, presumably the sun or stars. Thanks for the info, John Tinker 10/15/01 3:02:34 PM, "Peter C.

Almost Free, for pick up only in Michigan MicroPDP11/73

by fernande＠internet1.net

Hello All, Please respond privately.... this is going to two lists. I have a Micro PDP11 that I would like move to a new home. It is an 11/73 that uses the CPU board from the 11/83. It is the 18mhz J11 CPU with FPU (M8190-AE). It currently has 2megs of ECC memory, although I have about 3megs worth of parity that could be swapped in instead. Various other boards are included (no scsi boards :-) It is in the tower mounted BA23. The case is clean, but has a few flaws.... scratches and the base is cracked, and one of the little horns? where the back cover fits it cracked. Overall the case looks very nice. The steel chassis itself could use a vacuum, However. I could get into he ROM with a terminal, but never got it to boot from the RD54 HD. It complained of a bad controller (m7555). I have spares, but never tried them. It could be the drive as this particular PDP11 has a bad history with drives according to the documentation that came with it. The main reason I would like to move this on, is because I don't have the time to learn about it. I know nothing of the PDP11 OS's. Plus I have a Vax that I would like to get working, and lots of other little projects. In the subject line, I state "almost free". I do have some money in it, and would like to recoup at least some of it, so I'd like to get $40 for it. That's certainly much lower than what it would fetch on Ebay. I live in Battle Creek, MI. It's right off of I94 about 1/2 way in between Detroit and Chicago. Here is the info on the cpu board from the field guide: M8190-AE KDJ11-BF Q/U 11/83-84 CPU J11 CPU 18MHz with 2 boot & M8190-AE diagnostic ROMs, FPJ11-AA. M8190-AE Refs: EK-KDJ1B-UG, uNOTE N#025, N#030, N#035, N#039 Thanks, Chad Fernandez Michigan, USA

>Sometimes I have to power cycle the whole thing to get it to boot, do >I'm thinking that the drive might be going bad. If it doesn't boot when you first turn it on, you might not have let it come up to speed fully. It takes a good 20-30 seconds to come up to speed before you can turn the mac on. The drive light will turn on, then start blinking steady, after about 20 seconds, you will hear the drive click a whole lot, and the light will blink rapidly for about 2 seconds... after that, it is up to speed and safe to turn on the Mac and try booting. -chris <http://www.mythtech.net>

The card has trouble with high transfer rates. The on-board BIOS allows you to limit that to 5MB/s; when I slowed it down to that, it worked fine for me. YMMV (rather, HMMV), etc... -dq

I don't think the one that he's talking about is SCSI, it plugs directly into the floppy port on a Mac 128k or Mac 512K. ISTR, using one on a newer Mac Plus instead of a SCSI drive as I needed something of that formfactor and that was all I could get my hands on at the time. Based on how it's used, I'm guessing you're right about it being a MFM drive, but I suspect it's some wierd sort of bridge in it. Zane > I think I've got an old Hard Disk 20 and it's a SCSI device.

Anyone have one of these in use and could possibly be a source for a copy of the manual, disks, etc? Just bought one on auction but of course no docs or software and this is NOT SCSI to the server, it works on the LAN and has SCSI drives in it. Even if someone can send me the manual so I can scan or copy it and send it back that would be great too and maybe I might have something excess here (besdies actual cash to pay the shipping and materials back) to express my thanks.

Burroughs E6000

by mhstein＠usa.net

Ah, yes, remember them well, and the mechanical B series they replaced; might even still have some parts and ledger cards... Those were the days, programming with metal punches and tweaking and debugging with a file... made great desks when they were scrapped... But while on this topic, anybody out there doing anything with Burroughs L series or B80/90 systems? Have tossed most of it out, but still have some cards, manuals and a cassette drive with controller if anyone's at all interested. And of course some paper and mylar tape stuff... And some Burroughs calculator manuals, mechanical and electronic.. mike ---------------------------- Date: Sat, 13 Oct 2001 17:29:07 -0500 From: "Patrick L. Boland" <plboland(a)home.com> Subject: Re: Burroughs E6000 As late as 1977 ! was using two Burroughs E6000 computers to perform the function of loan payment application. The loans were for health club membership in the Chicago area and a great deal of the rest of the upper midwest area. We had over 50,000 loans outstanding at any time and processed from 1,000 to 3,000 loan payments a day. The machines we had were magnetic stripe ledger card readers and they would punch an output card with the results of the processing of the transaction. The latest information about the loan kept on a master deck of cards was replaced with the card that was punched as a result of the transaction on the E6000. The update was performed on a daily basis using the 085 sorter and a reproducer/collater. During the last 8 to 12 months of the use of the E6000, while a conversion was being worked on, we used only one E6000 and kept the other one for spare parts. Burroughs had run out of spare parts.

IIgs using hard disk 20

>Are you SURE? I have an HD20 which works just fine on a Plus, but which I >have NEVER been able to make work on a 128k. My 512k has video problems >and I haven't had a chance to sort those out so I can test the HD20 on it. Not to double reply... but now I am going to start beating my head into a wall. Apple's technote article # 8169 (in the archives section), claims that the only way to add a hard drive to the 128 and 512 is by using the HD20 non-scsi drive (the one in question here). This seems to contridict a previous technote that lists the first supporting mac as the 512ke. So now I am REALLY going to have to pull out my 128 and see what happens... it seems Apple doesn't even know which way it goes. -chris <http://www.mythtech.net>

It was the second generation before really complex LSI actually the '181 was likely the highest gate count part in the class before the TI bit slices (74881-884). It's also very old but still a handy part as it does all the standard arithmetic ops and logical ones too. The ALU core of the 2901 is basically the 74181. Allison

ArcNet and the Pursuit of Multiple Topologies

by jruschme＠Mac.com

Sounds a lot like a box I've been threatening to build for a while. On the Ethernet side, I'd not worry about specific 10bT and ThickNet segments. Instead, I'd run a single 10b2 (ThinNet) segment and get a 10bT hub with a BNC uplink. This also had the advantage of saving you a slot in the box. Don't worry about ThickNet, just pick up a couple of spare 10bT or 10b2 tranceivers for the odd box with an AUI port. Since you've got LocalTalk running to the box, then I'd also run MacGate which would let you run MacIP (IP over LocalTalk). As for other fun topologies, you already mentioned TokenRing. My personal choice would be to also add HomePNA (Ethernet over phonelines). The 1MB HomePNA 1.0 cards (the only ones supported by Linux)are very cheap these days. I picked up a pair from Computer Geeks (http://www.compgeeks.com) for something like $12. Now if I could just find a cheap Ethernet/HomePNA bridge for the Nubus Mac in the spare bedroom... <<<John>>> -----Original Message----- Date: Tue, 9 Oct 2001 12:50:01 -0500 From: Tarsi <tarsi(a)binhost.com> Subject: ArcNet and the Pursuit of Multiple Topologies Dear all, I've decided that one of my goals is to run every networking topology possible in my house, regardless if I actually NEED to run them or not. :) My plan is to place 1 linux box running a card from each topology in it and use that to bridge all (or almost all) topologies. I currently have running 10bT ethernet, 10b2 ethernet, Localtalk over PhoneNET and the beginnings of Arcnet. In light of such, I have a series of questions: 1) Who knows some stuff about ArcNet? I've gotten 4 cards (8-bit ISA) and a 16-port active hub. I've read somewhere that cards are either hubbable or not. Any other info on that? 2) Anyone have any (I think it is) 93ohm coax arcnet patch cables that they want to get rid of? 3) Anyone got good resources on ThickNET? (10b5 I think it is?) I know it was run back in the day, and I know some precursory things about it (the funky vampire taps, etc.) Anyone have either resources or hardware on this topology that they'd like to share/sell/etc? :) 4) Any other interesting topologies I should try? I have plans to do: Arcnet, FDDI, Token ring, Localtalk, 10b2, 10b5, 10bT, 10bTX, 10bFiber, and (eventually) 802.11b wireless.

OT: Dark Tower

by mythtech＠Mac.com

> What exactly IS Dark Tower? I've heard of Dork Tower (a comic book) but >not Dark Tower. If you prefer to answer off list, that would be fine too >8-) Well, if the original poster was refering to what I had, then Dark Tower is a board game (circa late 70's early 80's). The board was this roundish board that you moved all over, and there was a dark brown plastic castle thing that sat in the middle. The object was, you were an adventurer, and you had to move about getting things (treasures?) from each land (4 lands, 4 players IIRC). When it was your turn, you would press a button on the tower (I think there was "pass" for do nothing, "move" to go somewhere). It would then spin (well, the inside would spin, the tower stayed still), and eventually stop, telling you if you ran into enemy's, or treasures, or whatever. If it was an enemy, you had to fight them, and it would track your possestions and army strength, and would tell you how you did (how many people died, how many of the enemy joined your ranks, if you got new possestions) Basically, it was a 4 player, board game version along the lines of D&D (and was out when D&D was in its hayday, something else I am afraid to admit I was in to.). I would be happy to pull mine out (I am sure it is in my parents basement still, I have to go over there today anyway to fix my mother's computer), and I can take some pics of it, and scan the directions if people want. Of course, maybe the original poster was refering to some other Dark Tower game, and I now look like a total ass (but the one I know of was really cool, so even if I just get to tell others about it, it was worth the typing). -chris <http://www.mythtech.net>

CompuPro and 86-DOS

by mranalog＠home.com

This last weekend I pulled my old rack mount CompuPro system out of storage and cleaned it up. The last time I used this system was about 15 years ago and I only used it to edit my resume in Wordstar. The system consists of: a "CPU 8085/88" a "DISK 1" controller a "SYSTEM SUPPORT 1" for the console two "RAM 16" boards for a total of 128K and two Qume 842 8" floppy drives After one small capacitor fire I had the system up and running. I went through all of the 8" diskettes I could find to determine what would boot. So far, I have bootable disks for CP/M 2.2, CP/M 86, and CP/M 8-16. But the disks that I really want to read are in 86-DOS format according to the label. I have disks that claim to be 86-DOS boot disks but they wouldn't boot. Some of these disks I'm having problems with appear to be SSSD 26 sectors/ 128 bytes if that helps. Can anyone point me in the direction I need to go in order to be able to boot 86-DOS?

problems generating OS8 system tape.

by jos.mar＠bluewin.ch

After finally getting my TU56/TD8E setup operational, I now run into problems generating an OS/8 system tape. The system keeps insisting that "TAPE #2 is not an original dec tape", although i know for a fact that it is. I have 3 sets of system tapes and all generate the same error. Tape #1 is never asked for, the resulting tape is of course not usable. Any clues what I'm doing wrong ? Jos Dreesen

SCSI Info requested by David Woyciesjes

by dec.parts＠verizon.net

Hello David, I finally got at that info you requested. It turned out that there was some other related info that I thought you might like also. Probably more than you've ever wanted to know about SCSI, up to SCSI-3 info? Of course it was being stored on a SCSI drive that, at the time, wasn't hooked to this system, which is why I asked for your patience. Anyone who is interested must DL and save it within the next couple of days, as I have very limited web space and can't leave it there long. This is the only time I can post it. So, perhaps someone else with more space can host it for a longer period of time. http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi-info-15kb.htm http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi_faq-145kb.txt http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi2-spec-1632kb.txt Sincerely, Bennett

Slightly OT: What to do with a DEC 3000/300?

by ken＠seefried.com

Sorry to be late to this topic. As it happens, I've got a DEC 3000/300X (175MHz 21064, 64MB RAM, 2x2GB Disk, NetBSD 1.5.1 + fixes) in production. I'm fond of it, but probably more for the fact that it comes in a rackmount sled, which appears to be quite rare. It fits nice at the co-hosting facility (it's www.thistle.com, but it doesn't talk to anyone but me right now). What I know: Memory: No...you can't put just anything into it. It's got 8 72-pin SIMM slots, but it will only accept 8MB, true parity, generic SIMMs (giving 64MB). And it's damn finicky about those. My 3000s spits on SIMMs that everything else in the basement has no trouble with. It will also accept Digital custom 32MB true parity SIMMs (giving 256MB). Nothing else that I've found will work, but that could just be me. If anyone has any of these SIMMs they don't want, do let me know... Video: AFAIK, none of the free *nix systems support the built in TC frame buffers. VMS and OSF/1, nee Tru64 do. The 3000 will run X clients and display to another machine. Real men do serial consoles anyway. Speed: Slow. Really slow. Not PC532 slow, but not something I'd trade one of my PPro 200s for (other than the swanky rack-mount sled). Definately useful for low volume web, mail, etc., but "make build" isn't pleasant. My PC64-275 is way, way faster, but still not that fast. There's lot's of good info out there, and I know there are people working to support all that isn't currently supported. Drop me a note if anyone wants to know anything else. Ken

The stringy floppy is flawed the same way an 8-track audio tape is -- it only moves in one direction. As a result, A&J didn't write any OS for their drives, just a couple of simple commands. You search for the file you want, and you either find it (after several minutes) or you don't (after several minutes). > Anyone got a spare QOS wafer? Nope. Glen 0/0

Strange, but interesting, stuff. Ahh, neat! I've heard a bit about Wang VS systems, but I had no idea they were TTL CPUs. Very cool. How wide is the processor? The 74LS181 is 4 bits wide...how many does it use? Have you had a chance to take pics of this system? I'd be highly interested in seeing them if so. -Dave -- Dave McGuire Laurel, MD

Cromemco Pick-up on 10-13-01

by jrkeys＠concentric.net

This pass Saturday was a long drive MN to IL (12 hours total drive time) to pick up 2- Cromemco System Three's, a Systemv CS-300, one new in the box KB for these systems, lots of manuals and software for them, a Cipher 1600BPI tape unit, a model BRZ-III fan for the units, and some parts. All will have to be cleaned up as they are pretty dirty and need some loving care. The guy had over 1600sq feet of computer stuff he is selling most on eBay.:-( At a local thrift I got some Sega master stuff, like the 3D glasses that have been selling on eBay for $50, I got mine for a couple dollars. Got a Virtual Boy system for $11.99. Got some Atari 2600 stuff also they were selling cartridges for 80 cents and they had two big boxes full. Now I will start the clean-up and entering all the info into the database (my paper notebooks). Keep computing John
