Hi, I've saved two annexes from going into the 'dead machine' skip but haven't managed to talk to either of them yet. I'm planning to use them to give me console access to the two DEC workstation clusters that I'm building as a student research distributed systems test bed. I saw some mail on an Annex 3 but there is no 'Test' button on an Annex 2 - just a Normal/Diag switch and a reset button. I've tried powering on with the switch in diag and normal and terminal connected at 9600,4800,2400 and 1200 (all N-8-1) but, so far, no joy. Does anyone have any information on this model? Thanks, Nick. -- -- Nick Falkner -- PhD Student -- Distributed and High Performance Computing Group -- The University of Adelaide

Diablo 620 diasy-wheel impact printer needs home

by oldbear＠arctos.com

I have a Diablo 620 daisy-wheel impact printer available to anyone who would like it. This printer was carefully restored by the folks at Printerworks in Hayward, California in 1988 and was lightly used for about a year before being put in storage. It looks to be in excellent shape. It has its matching cable which can be configured as a serial RS-232 or parallel Centronics interface. It is capable of proportional spacing and uses a film ribbon for a nice letter quality impression. Unfortunately, I do not have software drivers for it, so you'd need to do some research. (Many word processing programs of the era included appropriate Diablo drivers.) I have a number of different font daisy wheels around here somewhere and should be able to find them to go with the printer. I am located close to Boston and would much prefer having it picked up than trying to properly pack it for shipping. However, I do have plenty of bubble wrap and might be able to find a big enough box to send it via UPS if someone wants to pay for the shipping. Please email me if your are interested. Regards, Will

poormans transputer

by rachael＠rachael.dyndns.org

I found a specialix si/xio multi serial port controler, sadly without the cables and actual link modules, it uses a ST t225 tranputer along with 64kb memory. As I looked at the linux software for it, it seems as I could upload a small program to it and make it run, Anyone tried such a thing ? While it might be a waste of good I/O card, without those external modules it aint much good, might as well have som fun with it. Would anyone happen to have drivers for a Newport system solutions inc. isa serial card, its a full length card using a nec v50. For this card I have everything except the drivers, Newport system is part of Cisco now, but their site doesnt hold much infomation about their old products. regards Jacob Dahl Pind -- CBM, Amiga,Vintage hardware collector Email: rachael(a)rachael.dyndns.org url: http://rachael.dyndns.org

netBSD 1.5 on a 1994 Mac68K

by cb＠mythtech.net

>The Mac's current chip is a XC68LC040RC33B. >I have a spare chip here, a XC68040HRC25M >which looks the wrong speed. The one you have will probably work anyway. But since it isn't cleared for 33 Mhz, it could fry (chances are it won't as Macs have usually faired pretty well at being overclocked). If you have no use for the 25 MHz version you have, I'd actually love to make a trade. I'm pretty sure the ones I pulled are all 33 MHz (I'll check in the morning), but since I planned to use them in Centris 610's which are only clocked at 20 MHz, I'd be fine with a 25 MHz chip instead. If you do have another use for it, no biggie, I'll still send you a full 040 chip (pending I have a 33 MHz one, but I'm pretty sure that is the only speed I have, they came from dead Quadra 630's which were 33 MHz machines) -chris <http://www.mythtech.net>

Several systems for sale or trade

by nospam212-classiccmp＠yahoo.com

I have several systems to trade or sell. Need to move them out. They're located in Houston TX and I'll give preference to anyone who can pick them up. Some I can't ship, too big, but some I can. Conditions are unknown as I haven't had time to work with any of these and don't suspect I will any time in the future. Not even sure what all is in each system. Thus, they're up for sale or trade. Ok, what is available... PDP-11/60 card bays and cards, power supplies and I think the front panel. No cabinet. Can't ship this. Kaypro 2 HP 715/100 HP 9000/300 HP 9836 - couple of key tops broken off but I still have them I can send pics of any of the systems for those that are interested. ----- "When the mind is free of any thought or judgement, then and only then can we know things as they are."

Qwint Systems?

Can anybody tell me anything about these? Found a little something I thought was word processor, but it actually looks like some sort of serial terminal using 80 column paper for output vs. a CRT. Very compact, kind of a neat looking little package. Googling has come up dry.....

Apple IIc Power Supply

by alhartman＠yahoo.com

I once had an Apple IIc that didn't have a power supply. Radio Shack sells a regulated 15v supply, rather inexpensively, and I bought that and made up a cable to go from that to the IIc. It worked nicely until the unit was stolen from my car. I've since gotten another with a monitor, the stand and a power supply. I am looking for a Laser128EX. I did a lot of programming on one of those, back in the day. Al __________________________________ Do you Yahoo!? Yahoo!

Visual Technology Terminals models 55 and 310

by d_cymbal＠hotmail.com

For those that followed my ADM3 terminal saga, most of the "Lear Sieglers" turned out to actually be the above terminals (there is still a "mystery terminal" that I can't ID, I am going to have to post a picture somewhere...) Most of these have manufacture dates at or about 1981. Anybody have any info on these? What they emulate, if they are of any interest, etc. Want to take one (or 5) off my hands ;-)

Free Computers in St. Louis - SGI 4D/310VGX, NEC APC, Altos 1086, IBM 5363 & 5247

by nick＠computer-history.org

I have several systems available free for pickup in St. Charles, Missouri, just outside of St. Louis. The systems are: NEC APC - This machine is complete but somewhat yellowed. It's an old 8086 CP/M system with two 8" floppy drives and a monochrome screen. SGI Iris 4D/310VGX - This machine is in very good condition. It's the size of a large dorm fridge and includes several boards but no hard drives. IBM 5363 System/36 - This is a small member of the IBM System/36 line. It is the size of a large PC tower and includes several hard drives. IBM 5247 - I think this is a hard disk unit for the IBM System/23 line of computers. It may work with others as well. Altos 1086 - This machine is the size of a large PC tower. This is an 80286 machine designed to run XENIX. I also have two SGI 20" color monitors available. If you are interested or have any questions you may contact me at nick(a)computer-history.org These machines are all quite large and are available for pickup only. If there are no takers you will probably see them on the Vintage Computer Market Place and then on eBay, they won't end up in the landfill. This shouldn't be considered a rescue, I'm just trying to make room for machines that I have more interest in. No software or manuals are included with any of the systems. Thanks, Nick

Dayton Hamvention (slight return)

by kahrs＠caip.rutgers.edu

To paraphrase my friend Bob: "It ain't Dayton if it don't rain". Friday was the best day in my 3 years of going. I do recall seeing a SPARC 5 on basically standing in a puddle. I saw several SPARCStations around as well as a Netra T1. Oh yes, a PILE of Data General multiprocessor 386 RAIDs (was this their last machine?). List price was $75 each. If you wanted soldering stuff, this was the year to go, lots of different irons and tips. Last year there was an oversupply of cables; I didn't see that this year. And lots of small capacity disks everywhere. At least it was warmer this year than last but the rain makes it difficult just because everything is covered. I'll go next year just because it's fun to see what's there. And to see how the maxim "One man's junk is another man's treasure" applies...

Still looking for the Alpha Microsystems VideoTrax PC interface

by vcf＠siconic.com

I'm still seeking out the PC interface for the Alpha Microsystems VideoTrax VHS tape drive. I've scored the drive (which is just a slightly modded Panasonic VCR) but I still need the interface, which is the last important piece of this puzzle I'm working on. I have no idea what it would look like exactly. It probably has some phono jacks on the back, and a one or two row header with anywhere from 4 to 8 pins. It probably is labeled "Alpha Microsystems". If anyone's got such a beast then you will be my New Best Friend :) Willing to pay good money. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

Nintendo GameBoy a valid discussion topic now?

HP computers / test gear in Chicago

by Innfogra＠aol.com

I see a HP 9820 or 30 in the pile, not to mention a HP 9825 and a HP 86. I want to go but it is too far. Looks like a great sale!!!! If anyone goes please post a report. It looks well worth going. Look for very old large 200 & 400 channel dataloggers. I have pulled a lot of core memory stacks from those. Some of the tube stuff will have tubes that are worth more than the instruments. Looks like lots of collectibles. I would love to know the history of the junkpile. It looks like someone has been going to auctions for a long time. Paxton Astoria, OR

Nonvolatile RAM on single board computers

by vax3900＠yahoo.com

I have a SBC with nonvolatile RAM on it. There are DRAM and EPROM too. I guess the nonvolatile RAM might be used to hold some important parameters while EPROM is used to hold program. Since nonvolatile RAM has limited life, I wonder how you guys deal with nonvolatile RAM in your old computers. Reading out the content with a EPROM programmer is a solution that jumps into my mind. "Burn" a new nonvolatile RAM and wait for another 10 years? It seems a boring work... vax, 3900 __________________________________ Do you Yahoo!?

Hi, I need to get rid of the following (it's not in line with what I'm interested in and it's taking up too much space): * Sun 4/110 with printer port and 2 SCSI ports * Sun 4/110 * Sun Sparc Server 490 (has 3 disks in base) (big) * 2 HP Apollo * Symbolics 3650 (heavy) * 2 extra color memory boards * extra 2MW memeory board * Monitor & keyboard * VAX Vector 6000-520 (big) * Sun 3/60 * 2 Sun 3/50 * 2 Sun Monochrome monitors (hey, they're monitors...heavy) * Original IBM PC (w 2 1/2 height floppy) * Original IBM PC (w floppy & HD) * AT&T 3B2/EXP * HP-UX tape set (4mm) Rev A.09.05 * HP-UX Install tape * HP-UX Runtime 2-user * HP-UX Runtime Support * X.25/9000 link * Focus for HP-UX * HP9000 Series 700 Customized S/W * Radio Shack TRS80 Model III (no floppies) I want this stuff gone! The whole point of this excersise is to get rid of this stuff so don't ask for board xyz-abc out of something. I'd prefer pickup, but if you're not local I'm sure we can work something out. I haven't tried powering any of this stuff so I'm not sure what works and what doesn't. -- TTFN - Guy

I took some pictures of the Millennium ICE and the Prolog M825 8085 System Analyzer. http://www.chd.dyndns.org/ICE/ The Millennium looks like the same manufacturer Joe R. was referring to, but a different model. -chuck

>> Both of mine had seriously burned in CRT's; I put in >> new ones I got for about $40 each shipped >Where did you get these. Have details of the swap out? The instructions for CRT replacement (at your own risk, etc etc) and the ROM replacement are linked from http://juliepalooza.8m.com/sl/adm%2D3a.htm I got the tube(s) from: http://www.cathoderaytubes.com The people were very knowledgeable and helpful; the tubes were less expensive than I thought that they would be-they are very common. But they even had CRT spares for my HP2644A (8008 based terminal-for $250.00! But I (physically) rebuilt that tube myself. The tubes were packed (not too suprisingly) very well. You need to know the P/N and mfg of the CRT (should be a label on it) before you call. My original tubes were made by 2 different manufacturers and were slightly different! ===== -Steve Loboyko Incredible wisdom actually found in a commerical fortune cookie: "When small men cast long shadows, then it is very late in the day."

My brother just got an apple //C, but it came without power supply.. I heard there was "cigarette lighter" adapter for the Apple IIC, Will the Apple IIC run on 12V? (the case says 15V 1.2Amps) Does anyone know where we can get a power supply? 2- will ProDOS run on 5 1/4" diskette? 3- Will DOS 3.3 run on 3 1/2" disks?

It's very simple but has all required data in one interface. http://dafc.rauch-grapengeter.de/ sorry, its all german, but you'll get the idea You will find the following data: -Name, Email (spam-treated), Collection-focus -Geographic position, (town + zip) handy to know who to ask if suddenly a nice machine comes up at the other side of the country that must be collected whitin xx days (or hours...) -Current inventory (as far as one likes to publish it) -Items for trade / sale, items sought after. -Machines cross reference with some photoos -Internal area, (passworded) there are e.g. phonenumbers and Ebay-aliasses to avoid useless competition between collectors. -Linklist -contactform http://www.geocities.com/computercollectors/index.htm is another site, but I will never list myself there due to the open presentation of the email-adresses, which just asks to be captured by spam-robots. So if you want to setup something, go head! I think it's useful. However, you may considder to seek some cooperation with one of the big vintage sites.

OT: Argh!

by julesrichardsonuk＠yahoo.co.uk

Now was not a good time to find that one of the disks in the fileserver has been slowly and silently corrupting itself for the past two weeks - it only manifested itself as a problem when the system was rebooted earlier though :-( 9GB of data down the pan - Grrr! It was all audio data on that drive, so yes I do have backups - on original media though. Gonna take a while to get that all converted to digital format again! Boy am I pissed! :-( Jules

Well, then again I don't have room for or ability to transport a full 19" rack either... But if the VAX system per se is not the rack but the rackmount units in it, is there perchance a way you could let me have those?? I want a VAXBI/XMI machine sooooo bad!

netBSD 1.5 on a 1994 Mac68K

I don't know what I'm referring to for FPU emulation. I just know I've seen messages about it pass thru the mac68k email list. Since I don't have any machines runing NetBSD that don't have an FPU, I've never paid much attention. I thought it was something on the netBSD side, but it could be a MacOS side thing for all I know. >There is an experimental 2.0 -msoft-float kernel and people have reported >good success with it, but my recommendation has always been that if you can >upgrade the machine to a full '040, just do it and use the stock kernel. >I'd reserve -msoft-float only for machines where this is not possible, like >the Blackbird PowerBooks, for example. Yup, and thus why when I was tossing some broken macs with full 040 chips, I pulled the chips to swap into things like my Centris 610's and 650's. That way, I can use them for mac68k later and not have any FPU headaches. I'm sure I still have a chip or two kicking around, so all John has to do is ask, and I'll be happy to send him one to swap into his 575 (if he is still using the 575 and in fact needs one. I can't be sure that I didn't do the swap before giving him the machine, but I don't think I did, because I don't think I knew he was going to use it for NetBSD). -chris <http://www.mythtech.net>

netBSD 1.5 on a 1994 Mac68K

by cb＠mythtech.net

>I'm thinking there's three possibilities right now: (1) mis-configured >swap space, (2) feeble SCSI driver + marginal SCSI drive specs, >(3) bad memory. There could be another cause; I don't know. >#1 seems most likely since all I've done is create the swap partition, >no config changes were made, but the /etc/fstab at least looks OK to me. >#2 has been hinted at by some documentation, but the disk load >went without hiccup. >#3 hasn't been seen within the MacOS (7.5.1) but I don't know any >serious tests for it. I'm certainly no BSD expert. But two issues come to mind. 1: I know there is an alternate SCSI setup for some drives. The default one doesn't work with all drives. I've only ever used the default and never had a problem, so I don't know what would indicate if you need the alternate setup. 2: Could any of this be due to a lack of an FPU? I *think* the Mac I gave you (if you are still on the same one we last talked about) I left with an LC040 in it. (that's the stock for the 575). I know netBSD prefers an FPU. I also know there is a software FPU patch that can be loaded to run on machines with the LC040 chip. I think Cameron may be able to give you better hints, he's got far more experience then I do (and has helped me a number of times) -chris <http://www.mythtech.net>

Let me also add that I'll be in the Bay Area on Memorial Day weekend (attending Conspiracy Con 2004 www.conspiracycon.com), so if the stuff is in San Jose as I've heard mentioned and there is something that would be takable for me and not already spoken for, then maybe I could take some. (Assuming it's something that can be fit in the baggage space under the Greyhound bus I'll be riding, or can be disassembled down to that size. Obviously a 19" rack wouldn't go, but I think a rackmountable *unit* would be OK.) MS

Attention Chicago Folks: Vintage Test Equipment Sale - Chicago

by cfandt＠netsync.net

Found this big sale mentioned on one of my ham radio-related email lists. Check out the pictures and prices! Condition of stuff may not be great, but anyway . . . Saturday May 22, 2004 from 9 AM to 2 PM Details and map at http://chicagotest.i8.com/BigSale.html Saw pictured at least one HP 9825, maybe a 9810, a Topaz "Ultra Isolator", a couple of 1611 logic analyzers, plotters, etc. along with a bunch of other nice, juicy early radio test gear within my interest. Wonder if there's any DEC or DG items in there nobody recognized to list or even a Tektronix TEK 30 . . . Wish I was nearby, dang it! Please let us know if anybody went to the sale and give us a report. -Chris F.

Manual for HP 82928A System Monitor?

82928A System monitor: Provides the necessary hardware to aid in developing and debugging assembly language programs for HP Series 80 Personal Computers. The HP 00085-15007 (or 00087-15007), 82928A and 82929A form a complete set of tools. The 82928A System monitor is described in the HP85 Assembler ROM manual. This manual is currently available on the MoHPC CDROM (http://www.hpmuseum.org) collection (if you are interested in the 85 then purchasing the MpHPC collection should be a priority as it also contains the 85 service manual). Somebody has promised me a scan of the 85 assembler manual, so it should appear shortly in the www.series80.org site as well. Last but certainly not least is John Shadbolt's site (http://www.vintagecomputers.freeserve.co.uk/hp80) **vp

AIM65 test program?

by rcini＠optonline.net

Hello, all: While browsing an early-1980 issue of Compute magazine, I saw a blurb for Rockwell offering copies of the manufacturing test program for the AIM 65 computer. The blurb references a test manual (#EA74-M800) and a test program listing (#EA74-J100). It also indicates that on the manufacturing line, two EPROMs with the test program are installed in the BASIC ROM slots. Does anyone have either manual or the ROMs in question? Thanks. Rich

DEC RK07 drive interface specs wanted

by jkunz＠unixag-kl.fh-kl.de

Hi. All this talk about frontpanel emulators... So I have this (mostly) working PDP-11/34, my one and only UniBus machine. It came with a RK07 drive. But the system was stored under bad conditions for years. There is rust and corrosion _everywhere_. The machine works so far but the drive is quite rotten. I have no other UniBus disk drive interfaces so I need either a new RK07 (unlikely) or a replacement for the entire conroler / drive combination or: What about a RK07 drive emulating hardware? A microcontroler with some TTLs to interface to the RK611 controler on one side and a compact FLASH card on the other. Maybe cache RAM in front of the FLASH to reduce write cycles to the FLASH. 32 MB is enough for a RK07 disk, even if the emulator stores raw data including all sector headers / trailers. Problem: Exact and detaild specs of the RK611 <=> RK0[67] interface. I found some hints in the "RK06/RK07 Disk Drive User's Manual" but not enough to build a new drive from scratch. Any pointers? -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/

I just finished adding some pictures of the core memory boards from the UYK-20 to my website at <http://www.classiccmp.org/hp/UYK-20/>. This <http://www.classiccmp.org/hp/UYK-20/back.jpg> is a picture of the back of one memory card with a 3.5" floppy disk laying on it for size comparision. This <http://www.classiccmp.org/hp/UYK-20/top.jpg> is a picture of the top. The core is under the green cover. Here is a close-up of the Sperry Univac logo on the memory board. And finally, here <http://www.classiccmp.org/hp/UYK-20/core.jpg> is a picture of the core itself. You can get an idea of the size of the core area in comparision with the 3.5" floppy disk in the LH edge of the picture. The green over comes off very easily. Just remove four screws and it slides off. Lyle Bickley send me a couple of PDF files about the UYK-20 and I've posted them on the same webpage. Joe

Beehive: was Lear Siegler ADM3 terminals

by Innfogra＠aol.com

I think Beehives are much more rarer than ADMs of any kind. Beehives were highly sought after by my scrapper as they had an aluminum case and good cards. He actively sought out Beehives as one of the best terminals to scrap along with the early Sorocs and went out of his way to search them out. As a result there are few Intel ones in PDX. ADMs survived by having very poor scrap values and high disposal costs for the plastic case. Paxton Astoria, OR

Lear Siegler ADM3 terminals

by sloboyko＠yahoo.com

These terminals are very nice; I have a brown one and a blue one. One part that always breaks or is missing is the flap on the front for the DIP switches. I made aluminum plates to fit in the recess. Both of mine had seriously burned in CRT's; I put in new ones I got for about $40 each shipped (I hate this kind of work, but I did it) and now they look and feel new. I opted for B/W for "originality", although I could have gotten green phosphor at the same price. One didn't have the lower case option; the chip for lower case is hard to find. So I copied the ROM out of the ADM-3 with lower case (2kx8, strange voltages and pinouts, a 2513-type ROM), blew a 2716, and made a little adapter to plug into the other ADM-3's 2513 socket. This, two 2102-1 RAMs, and a few flips of dip switches gave me lower case! Absolutely hideous matrix, but very authentic! ===== -Steve Loboyko Incredible wisdom actually found in a commerical fortune cookie: "When small men cast long shadows, then it is very late in the day."

Nonvolatile RAM on single board computers

by dwight.elvey＠amd.com

Hi I usually make copies on two diferent media. I make a copy on another similar device and also a 3.5 floppy. I keep these with the unit. Have you played with the SBC any? What kind is it? These are always interesting to collect because of the chalenges of locating software and documentation for them. I've been known to connect up a switch panel to a uP socket and use this to determine the addresses of ports and memory. I did this on a 80C186 machine and implemented a Forth on it so that I could play with it. Development boards are also fun to play with. I have a few of these.

New pictures; UYK-20 Computer and Millennium uProcessor System tester

by rigdonj＠cfl.rr.com

I've added some more pictures to my website. The first ones are of one of the UYK-20 computers. These were made by Sperry Rand and are militry versions of the Univac and use core memory. <http://www.classiccmp.org/hp/UYK-20/>. The other pictures <http://www.classiccmp.org/hp/millennium/> are of the Millennium microproccessor tester that was discussed here a few weeks ago. I took these pictures in a hurry and they aren't real good, particularly the ones of the Millennium. It was in the back of a dark warehouse and the pictures show it. One item of interest on the Millennium is the pullout drawer on the side. It has the CPU and all of the CPU spcific items on it. In other words, you can change it from an 8080 system to a 6800 system by merely changeing that drawer. I have two of these and IIRC one is 6800 and the other is 8080 based. Joe

Altos 686

by bmachacek＠pcisys.net

I just noticed I have an Altos 686 (without a cover) PC in my stack of 'old computer stuff'. It's s model 25A with one 5 1/4 inch floppy drive and a Seagate ST225 hard drive. Is this one of Altos computers that people are interested in or something that needs to be scrapped? Thanks for any help you can give me. Bill Machacek

DECmate II

by aw288＠osfn.org

Another item that will be leaving my collection (mostly because I never did anything with it) is a DECmate II - the micro version of the PDP-8 (Intersil 6120 based, I think). A couple of questions, as I would like to test the thing out before I offer it to anyone. 1) Whay kind of video is "video"? Some sort of odd tube? Whatever it is, I don't have it so I am hoping the box supports a dumb terminal. 2) Will I boot this up from a dumb terminal (VT100, my guess)? What are the specifics? This machine is in decent condition, with an RX50 and a hard disk of some sort. I have no manuals. William Donzelli aw288(a)osfn.org

Sun Ultra 1 questions

by julesrichardsonuk＠yahoo.co.uk

See my other post about the Ultra 1 I found. (I think it's a couple of years too new to be on-topic - sorry!) I put the pair of memory sticks in there which I got in the same day and tried powering the machine up using a terminal as the console. Amazingly, it's alive! At the moment it's set to boot from the network - any idea how I can interrupt that and get into the boot monitor in order to switch that off? I think there's some key combination to do it from a keyboard, but of course I don't have one handy at the moment - just the console. There's a clear perspex bracket above the CPU for holding a fan, but no fan. As this machine had been stripped before I got it, I don't know if it should have one and someone had taken it out. The CPU has a large finned heatsink on it - on the web I saw a vague report that Sun may have stopped putting fans in the machines on later ones and just used a larger heatsink. Any ideas? Finally, any clue as to whether the Apple SCSI CDROM I got will work in the Ultra? It's a 1993 vintage drive, an "AppleCD 300 Plus". If not, I do have a SCSI drive that'll do both 512 and 2048 block sizes, but it's in a running machine at the moment... No idea why this machine was thrown out. It seems to work so far. Maybe it has an intermittant fault when it's been running for a while, or maybe the network interface is dead (according to console messages it notices when a cable's present or not though). cheers Jules

It's also worth pointing out that by the '80s, some of the boards required diagnostics and equipment that it wasn't practical for every field service guy to carry. A lot of companies did as the one I worked for: field service engineers were trained (quite carefully) to pin a problem down to a board, replace that, and send the faulty one to their central workshop (ours was in Stoke) where it would be repaired and tested. There's nothing wrong with swapping a board providing you know which to swap (implying "why", at some level) and the faulty one gets fixed (assuming it's economic). -- Pete Peter Turnbull Network Manager University of York

DEC ROM and RAM boards

by Lee.Davison＠merlincommunications.com

Remembered to bring the details ... The ROM board is marked .. "5419803 5019802-01 A1" and "ROM DWT CARD" .. and holds 14 27C010 1Mb EPROMs. The back has a label saying "VT1000 2.2" I can use these EPROMs so if no one needs them or the contents they'll be recycled next week. The RAM card is marked .. "5019806" and "5419807" .. and has one 1MB SIMM marked .. "5419805" .. I have no use for this at all.

RSTS/E and PDP 11/23

by wacarder＠usit.net

I acquired a PDP 11/23 this weekend. It runs RT-11, which boots fine from either the RL01 or RX01s. Has anyone ever attempted to run RSTS/E on an 11/23? I was thinking about attempting to SYSGEN RSTS/E v7.0 on this machine, but in looking over some info on RSTS/E, it does not list the 11/23 as one of the systems that RSTS/E will run on. Ashley

Update on Trip, opinions on purchases...

by zmerch＠30below.com

Well, amazingly, I'm still alive after my trip to the Dayton Hamvention... ;-) Got down there Friday nite, so I didn't get any chance to peruse the flea-market booths then (which is when I'm told most of the classic schtuff is available...) on Saturday, it rained like a ... Well, a lot. It didn't ease off until about 1600hrs, when I finally figured I'd "venture out into the wilderness", so most vendors were still wrapped up prolly figuring the entire day was a lost cause & went to drown their sorrows. I did see a Heathkit EPROM burner (4800? methinks) - guy wanted $50 but "might" take $40. I told him I'd think about it, it was gone Sunday. (It did have the personality modules up to a 27256.) Dunno if it was a good buy or not. That was all I saw for classic gear (other than PeeCees that were 10+ years old, I'm not counting that due to the boredom associated with said particular platform. ;-) [1] Sunday was nicer, overcast but warmer & no rain, so it was a good day to do some exploring, and all I saw was a TI-44/9a with 1 cart for $20, an unpriced Apple //e, and some unpriced assorted Suns. Altho I'm not "the most worldly wize d00d on the planet" I do know that most of the time, if it's unmarked, the price doubles when you ask. I generally don't waste my time or theirs. ;-) Nothing Tandy-ish, let alone Model 10x/200 which is what I was hoping for... :-( As a lead-in to another thread, tho, I did pick up a soldering station & desoldering gun. For $100 I got a Hakko 939 soldering station w/1 tip (it's fine for medium work, but for some fine circuitry I'd want a finer tip), photocopied manual, and key (yes, you need a small "punch-card" key to change the temperature & the configuration... each tip has a "temperature coefficient" that you key into the station, to keep an exact temperature, AFAICT)... Anyone else have any experience with this brand/model of soldering station? The cheapest I'd found on ePay (tho I didn't search completed auctions yet) was $150, and it looks like they still make 'em for about $400, so I think I did OK... I also snagged a $65 Soder-Wick SC-5000 desoldering gun. My only concern is that the guy told me the filters are no longer being produced for this model (he had the SC-7000, but I didn't have the $475 required to purchase the rascal). I've already googled around a bit for this model, and I got 1 website: His. The filter on it right now is "nearly new" and he stated that it would take me a long time to wear that filter out, but I'm still concerned about finding replacements. Anyone know or use this model? Oh, and I did find an AUI transceiver for my Vaxstation so when I have the room to set that up again... Externally powered (never seen one of those before) w/wallwart, $3. Not too bad... ;-) Laterz, Roger "Merch" Merchberger [1] and there were a *lot* of them. Anything from a '386 & up could be had for anywhere from super-cheap to "what the hell are you smoking" prices. Sad, really... -- Roger "Merch" Merchberger | JC: "Like those people in Celeronville!" sysadmin, Iceberg Computers | Me: "Don't you mean Silicon Valley???" zmerch(a)30below.com | JC: "Yea, that's the place!" | JC == Jeremy Christian

DEC handbook series - official list?

by waltje＠pdp11.nl

Hi all! While attempting to get some organization back into one of my study rooms (the one where all my DEC docs and media are), I again ran into the problem of organizing my collection of the wellknown "Handbook" series of DEC publications. I have many, but after sorting them out, and taking out the dupes (which *are* available for trade, by the way) I noticed some volumes were clearly missing in series where they had multiple-volume issues. So, is there (from DEC, or collected by us) some sort of "master list" of which handbooks were published by DEC? This would help me a lot in finding the ones I am missing, or think I am missing...

new finds (Acorn, Sun, Apple)

by julesrichardsonuk＠yahoo.co.uk

The following turned up yesterday from a couple of skips: Two Acorn 420/1 machines, one with an ST506 drive and the other with an IDE drive and interface. One has an Ethernet board fitted. Both seem to have some sort of CPU upgrade fitted to them. An Acorn A5000, with a board called a "Colourcard" in it - I assume it's some sort of video board with a better spec than the standard video output? I got keyboards and mice for all three machines, which was nice. Also found two seperate Ethernet cards, a whole slew of RiscOS ROMs in a box, Artworks software and a pile of Artworks dongles. Oh, and a collection of the rear panel blanking plates (I'm actually missing those from some of my Acorns, so they'll come in handy :-) I also came away with Sun Sparc 4 (gutted though), a Sun Sparc 10 (memory and CPU board fitted, no hard disk), and a Sun Ultra 1 (also gutted). Couple of Mac LC III's were in the haul too, a couple of Apple Ethernet boards, an Apple SCSI CDROM drive, plus misc. bits - a 760MB full-height SCSI drive, several small-capacity IDE drives, couple of sticks of Sun memory, couple of RS232 gender changers etc. I passed on the huge Apple Quadra tower that was in the skip, and the numerous PCs that were in there... :) Not a bad haul for free though. cheers Jules

DEC boards

by Lee.Davison＠merlincommunications.com

Found in the bin this weekend at Drayton Manor Radio Rally. One EPROM board with 12 27C010 EPROMs and a label on the back saying "VT1000 2.2". One SIMM carrier board with three 64 pin SIMM slots, one populated with a 1MB SIMM. Are these any use to anyone? I can dump the EPROM contents if needed. I did make a note of the DEC part numbers but left it at home (doh!).

new finds (Acorn, Sun, Apple)

by cb＠mythtech.net

>I don't think it was *that* good. I'm certain it was only three numbers, >not four. It could well have been a 950 - given the dusty dirty skip it >was lying it it's not impossible to believe that dirt made the 5 look >like a 6 :-) What may be tell tale is, did you actually see the name Quadra on it (I came in late, so I responded before without realizing you called it a Quadra). If so, then it is not a 9600. A large tower with Quadra on the name plate would be a 900 or 950 (there were no 96x in the Quadra line, although there were some 6xx, but no 69x and the 6 series were all desktop cases, not towers). Slightly smaller tower would be the 8xx series A Q950 still isn't a bad machine, but not as big of a deal to abondon (I have a WorkGroup Server 95 which is the Quadra 950 with a different software package). -chris <http://www.mythtech.net>

UGH... go back and get it. You probably left behind a PowerMac 9600! DAMN good Macs. Fully upgradable to a G4 processor, and it has 6 PCI slots (last Mac to have 6 slots, and one of the few to ever have that many). They sell used for $100 with stock processors (200-350 MHz IIRC). Grab it, buy a $100 G3 or G4 processor upgrade, and have a 6 slot OS X runnable Mac (OS X requires the patch from XLR8 to install, but it will work once installed). -chris <http://www.mythtech.net>

opinions on very long term storage and references from Google search

by mmcfadden＠cmh.edu

\begin opinion Seems like the best method for very long term storage in theory is ion beam on iridium disk More practical methods include the following: I have also heard that using archival quality ink in a retrofitted ink jet printer printed on acid-free paper may work for reasonable amounts of time. The plastic ink particles in laser toner are very susceptible to environmental factors. I know that for land surveys that archival ink using a pen plotter on vellum is "best". \end opinion References http://www.uky.edu/~kiernan/DL/hedstrom.html Digital preservation: a time bomb for Digital Libraries. www.tims-im.ca/Whitepapers/22010v052p.pdf Preserving Information Forever and a Call for Emulators.

The Lyman books on bullet casting have some good explanations and charts on this. Joe

Original 11/23 *backplanes* are 18-bit, though they can be rewired to be 22-bit. AFAIR, the only 18-bit 11/23 CPU was the Rev.A KDF11-A (the first dual-height one). -- Pete Peter Turnbull Network Manager University of York

IBM AT Free to a Good Home

by bill＠timeguy.com

I have an IBM AT with all original docs and keyboard, in like-new condition from the original owner. It can be yours for the price of shipping. Note that it has an upgrade VGA video card in place of the usual mono or CGA/EGA card, and that it currently will not boot from the hard drive (which is why he finally upgraded to a PC made in the last 20 years). A 14" VGA monitor, IBM ProPrinter, and Okidata 320 printer are also available as part of the bundle. E-mail if you have questions or want the thing. Note that I ship via Mailboxes Etc. so be prepared to pay their packing/shipping rates or arrange to pick it up.

Computer Estate( and collecting)

by mmcfadden＠cmh.edu

There are many areas of "collectors" that can't give up any parts of their collections. My grandfather had an old corn crib that was full of partial parts and containers of stuff from the orchard and farm. There were tractor parts, mower parts, sprayer parts, wagon parts, and picking bags. You could not just drive to the store for a part when something failed. After he died I looked through it, saved some unique items and it was an education of how farming used to be versus what it is today. I don't think he thought he was a collector just a farmer. Currently I have neighbors who are sailors and their back lots are a collection of boat parts. I have seen more hasty repairs from the collections. The local community would like to clean up "junk" however one person's junk is another's treasure. It's probably related to availability, if you have a broken boat and need a part then the closest part is the best. Then there are the car people! I don't know enough to comment. You have never seen stuff until you meet some "horse people", they have more tack, ribbons and stuff than most. I'm the computer person. The nice thing about computers is they don't eat, and need veterinarians. This weekend is a general community cleanup and I'm keeping my eyes open for any neat computer stuff. Last year I got an HP 7550 pen plotter >from the dumpster. Of course I will have to negotiate with my wife. Mike

Sparc 10 PSU connector pinout anyone?

by julesrichardsonuk＠yahoo.co.uk

Looks like the Ultra doesn't need any more attention to convince me it's working, so I just tried the Sparc 10. The fans spin, and I'm getting good +5 and +12V on the hard disk power connector, but no power LED and no console activity. I notice that (apart from the pin nearest the PSU, which is at +5V), all the other pins along the frontmost row of the PSU connector register no voltage, which *could* be a problem. Anyone have the proper pinout handy? (At least this machine's on topic :-) cheers Jules
