Intel 4004 from discrete SMD transistors

by wbblair3＠yahoo.com

> http://www.4004.com/ I forgot to point out that they are still requesting volunteers at the project web page linked to above (under the "How can I contact you?" heading). I'm surprised that I can't find anywhere on-line a project to create an entire MCS4 system on a single, low-end FPGA. Am I just missing it?

COBOL quote in the news

by cclist＠sydex.com

>From http://www.sacbee.com/111/story/1132588.html concerning the California budget crisis: The state payroll system is based on the COBOL, or Common Business Oriented Language, programming language - a code first introduced in 1959 and popularized in the 1960s and 1970s. "COBOL programmers are hard to come by these days," said Fred Forrer, the Sacramento-based CEO of MGT of America, a public-sector consulting firm. "It's certainly not a language that is taught. Oftentimes, you have to rely on retired annuitants to come back and help maintain the system until you're able to find a replacement." What does California's DMV use? Cheers, Chuck

IBM EGA Programming manual: anyone have a copy?

by Watzman＠neo.rr.com

I have a copy of it (original IBM EGA manual), apparently I made it back in the 1980's, it's definitely a copy but it's exactly like the original (e.g. double sided in the original 5.5 x 8.5 format). It's 168 pages ... it would be a hell of a job to scan or copy, and since it's an odd page size, I can't run it through an ADF "automatically".

WTD: DEC 11/40 power supply (main unit) model H74

by billdeg＠degnanco.com

The part number on the front is "H74 a" and it's the big part of the power supply in the back. In front (looking from the side) are 5 "h754" modules. The modules and the console power are attached to the "H74 a" Other H74x supplies should work. Here is the wording on the unit: Dec Power Supply H74 a Caution AC & DC OUTPUTS ARE PRESENT WHEN LIGHT IS ON POWER ON (( )) ------------ where (( )) = the light bulb. System was working recently.....The supply's red indicator light no longer comes on, nor do the console lights, though the fans still run. In the meantime I will test with a volt meter and so on, maybe there's a bad connection. Thanks in advance Bill

Hi, I have a cad system (Altium), which can convert some formats, maybe I could convert EAGLE files. But, if you tell me, how the final board should be, and its not so much work, I can do it for you and you get Gerber files, which are accepted by most of the PCB manufactures. Cheers Gerhard

Barbie PC

by alhartman＠yahoo.com

Barbie PC's are VERY expandable. They have 4 USB ports (at least the one I have does), so you can easily put a USB hub on there to have even more ports. I've put USB wiireless adapters, USB NIC adapters on my sisters. I've put a 512mb RAM DIMM in it, and put a better CD-ROM drive in it. It came with Windows 98, but runs fine on Windows XP Home or Pro. It's not a top end box at all, but can be a nice Internet/Wordprocessing computer. There was also a Hot Wheels Computer which had a Blue and Yellow case with Flame stickers on it. Changing out the battery is no big deal. I just did that for my sisters unit. They are old and slow, but I'm sure there are lots of uses for them. Al

More ETH Lilith goodies available

by julianskidmore＠yahoo.com

Hi folks, >CPLD's are cheap and easy to program now days. > I suspect getting high speed 2901's and proms > for any micro-programed machine is tricky. Over the past 6 to 9 months I've become rather intrigued about Lilith. One of the great things about the design of MCode (the Lilith's stack-based bytecode) is that it lends itself to being emulated directly by a Microcontroller, rather than emulating the machine at a Microcode level (170ns / microinstruction). My preliminary calculations imply that a low-end 60MHz ARM Microcontroller attached to 128k (or 256K of RAM) could emulate a Lilith in this way at full-speed even if it didn't have a proper memory bus (i.e you access the RAM via I/O Ports). > I suspect 16bit addressing and data seems to be the limiting > factor of this design. The later Liliths accessed memory as 2 banks of 64KW => 256Kb in total. >>> But can one build the hardware from scratch? >>> None of this software emulation. Well, I suppose the ARM version would be software emulation, but on the other hand, it's a dedicated hardware / software combination and it'd probably give you a Lilith for around $12! ... I wonder if MIT & India would be interested ;-) -cheers from Julz @P

by jos.mar＠bluewin.ch

Those with an interest in the ETH Lilith Modula-2 should point their FTP clients to ftp://jdreesen.dyndns.org/ftp/lilith where they will find plenty of data concerning that machine. Most important is a binary image of the Lilith Systemdisk, and a directory containing all files ( more then 700..) of that systemdisk. Among these files are : Medos binaries and source code. Modula-2 compiler binaries with source code. Lilith system utilities with source code. Bootfiles and system files. Microcode sources and assembler Manual Also available are hardware docu and some screenshots. Enjoy , Jos Dreesen Server is on a basic DSL line, so download speeds will vary....

They mostly did .gov work and a lot of her work went to NASA and defense work. She would bring home reject work that had not been "capped" (open top, die, pins and bonding wires visible). I remember her making some into jewelry. They were so unusual at the time that they attracted a lot of attention. BTW, a bonder soldered the hair thin gold wire from the "chip" (dice) to the carrier legs (pins). They used stereo microscopes and it was precision work.

LocalTalk

> Date: Tue, 05 Aug 2008 16:17:32 -0400 > From: Sridhar Ayengar <ploopster at gmail.com> > Subject: LocalTalk > > Hi. I'm looking for a LocalTalk->Ethernet bridge and some LocalTalk > cables. Anyone have any available? I don't have one available but the product names you are looking for include: AsantePrint MicroAsanteprint AsanteTalk in order from oldest to more recent. All three of those were by Asante. There were similar products from Farallon and Dayna, but I do not remember the specific product names. All of those will bridge from LocalTalk to Ethernet, but I think they only bridge the AppleTalk protocols and not TCP/IP. The latter two are about the size of a deck of cards and pretty much look identical, except there's a variation on the middle one with a BNC connector in addition to the RJ45 jack. The earlier two have more network management features which one is unlikely to use in a home network. For LocalTalk cabling, unless there's some reason you really want to use original LocalTalk cabling, you should get PhoneNet connectors and use phone cable for the connections. The PhoneNet connectors are a dongle (available in many different brands) which plug into the serial (LocalTalk) port and have two RJ11 jacks on the other end. The RJ11 jacks can be used to form a daisy chain network. If a PhoneNet connector is at the end of the chain (only one jack used) then the unused jack should have a terminating resistor installed. I don't remember the value. Finally, PhoneNet uses the two wires in four conductor cable, which the telephone system does not use (yellow/black vs. red/green). However, there are a lot of telephone cables out there shipped with modems which only include the telephone pair and not the pair which PhoneNet needs. You can spend a lot of time trying to diagnose a PhoneNet connectivity problem when the necessary wires are absent from your cable. :-) When ethernet became very affordable, old PhoneNet equipment was more or less being given away free. Most of it has been disposed of by now, so it may be a bit challenging to find, but probably not too challenging. I remember seeing a lot of 150 PhoneNet dongles go for something like $.99 plus shipping. :-) But that was probably eight years ago. Jeff Walther

My first Computer job was for a Data Processing Outfit in New Jersey as a Computer room Operator. One day they brought in a Machine "Datapoint 2200" and I said I can program that. I had gone to a Programmers school a couple of years before. I at some point dumped the Datapoint's 8K of memory to the Printer then decoded it and re-assembled a program written in Assembly to intake three 11 line screens of data. It had Interrupts and You could even back track fields to correct them. Took me six months. Gave it to the Rep who eventually slid it into the Round File where some of my Best work ended up over the years. Wish I had been able to save the listing. The Manual for the editor said "Go have a cup of coffee while your files were being copied from the rear cassette to the front. I was still working on the Datapoint's in 1979 when I left the firm and moved to Wisconsin. I moved on to CP/M then the PC's as well as Learning how to Program for the IBM Series/1 in EDL. Now there was a Language. Still got a 110 Volt IBM 4952 in the Basement but never got it running. Wish I could find a GURU who could help me get it up and running. Kick my self for not doing it back in the early 90's when I brought it home. I was doing consulting on the Series/1 then but didn't find the time. Oh Well Bob in Wisconsin

Where to find memory ICs?

by trixter＠oldskool.org

Have a working Intel Above Board Plus 8 with 2MB RAM and would like to populate it to the full 8MB. It will take 120ns or faster 1mbit chips -- but where can one find that kind of thing nowadays? Are those still commercially available or am I going to have to scavenge them from somewhere else? Manual lists acceptable part numbers like: Fujitsu MB81C1000P-xx Hitachi HM511000P-xxS Mitsubishi M5M41000AP-xx Motorola M5M511000P-xx NEC UPD421000C-xx NMB AAA1M100-xx OKI M511000RS-xx Samsung KM41C1000P-xx TI TMS4C1024-xx Toshiba TC511000P-xx ...etc but google searches haven't been very fruitful (that is, the pages returned when I search for IC part numbers don't return vendors with plain pricing/availability info). I just want a few tubes of these to populate the board, I'm not looking for a box of 'em :-) Any pointers? -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/

It is really a shame that no one has been able or willing to have one scanned, but that would take a LOT of work - the manual is over an inch thick. Without proper OCR it would be a PDF of pictures, which load very slowly and would make the scan huge. I've seen quite a few manuals done this way and they aren't nearly as usable as the OCR'd variety. I thought about scanning mine back in 2003, and even bought a flat-bed scanner w/OCR software, but it wasn't up to the job at that time. Better equipment and software would have been necessary, along with cutting away the spine of the manual. Today there are better and more affordable solutions, but I am not up to doing it as my health has forced me to retire. I'm not willing to sell my manual in case anyone is wondering, sorry. This looks like an opportunity for someone with the manual, proper equipment, and time - anyone? Simon, do you have the required setup to do this without damaging the book?

When anyone with a tech company says "We can't find anyone to do X" what they really mean is "We can't find any new graduates to do X" because heaven forbid they should hire an older (like over 35) worker. There are plenty of older tech experienced folks working at hardware stores, who would jump at an entry level tech salary, but for some reason, human resource drones in tech companies are universally convinced that they would be too expensive or otherwise a poor choice. Sigh. <happy I have a good job finally> It's the same story as a few months back when B. Gates went before congress and asked for more H1Bs claiming he couldn't find any programmers. Jeff Walther

segmented memory models

by segin2005＠gmail.com

Note: This was written at a eariler date than mailed. This is due to the fact I personally do not have a net connection and read email whenever and however I find a unsecure IEEE 802.11g "Wi-fi" access point. As of such, I ask that would someone please be so kind as to compile all relevant replies to this email into a digest and email that to me, as at the last time I checked my email, I had over thirty thousand unread email messages (30,069 to be exact) from over the last 20 months or more and I am simply too lazy to junk them all -- it's a GMail account and the ratio of incoming daily mail to storage growth is low enough that accumulating email appears to be a non-issue, even with 3 very high volume mailing lists subscribed; wine-dev, cctalk, and I think LKML. (Normally, I sort this all out using a rather ad-hoc set of regexp filters in Thunderbird) My question is rather perplexing. When most people refer to segmented memory, AFAIK, they mean banked memory systems, where each segment is like a piece of paper, that is, seperate from each other. On the contrary, the Intel 8086's segmented memory model is like lessing some source code and using the terminal arrow keys or K/L to move the display one line; given segment X, segment X+1 contains almost all of the memory of segment x, except for a new line of 16 bytes (which the metaphor between a new line in 'less' and the segment differential is rather ironic; most hex editors I have seen display exactly 16 bytes of data per line) The question is, is the Intel 8086's memory model brain-damaged? IMHO, extremely much so.

question aaout ISP's

by James＠jdfogg.com

> I'm based in Philadelphia. My current provided is disabling > telnet capability at the beginning of September. I would like > to know if anyone knows of a service that will permit me that > capability? > bs Don't use standard ports. My provider (Comcast) blocks port 25 (mail) inbound and outbound, and doesn't allow relaying through its mail servers. Instead I use port 2525 and an external mail relay service. With telnet, you won't need a relay service if anyone accessing your system knows that it's on a non-standard port. Do you really need telnet though? SSH preferable if your host can run it.

AT&T 3B1 Unix PC

by mikelee＠tdh.com

Anyone collect and/or need parts to the AT&T Unix PC? I've got a pile of systems I dismantled over a decade ago, and don't really want or know how to put back together. I bought them "new" as surplus by the pallet at the time, and about half of them were defective with only displaying horizontal lines when turned on. The monitors are perfect, I also have the 20Mb MFM drives and 5.25" drives, as well as the mainboards, plastics etc. I'm not sure exactly how many and what I have yet, but checking for interest here. Please reply if these are of interest at all. Any suggestions on the line problem? Mike Lee

my mac SE problems

by jlobocki＠gmail.com

ok, so i got a mac SE off ebay, for a decent deal. now a logic board, floppy drive, CRT tube (I let the magic gas out of the first one) later, im back where i started. i write a boot disk with my powerbook 1400cs, pop it in. it boots up to the system software. i go to hd sc setup like i did when i used my external floppy to boot, and it shows nothing. the first time, i got to boot with an external floppy and the old logic board, and it showed the drive until i attempted to format it, which it wouldnt. after that, i couldnt see the drive again, and my boot disk kept getting wiped each use, and id have to reload it. so then, i replaced the board, the CRT, and the floppy, and now its still doing the same damn thing as it was before. is it possible i need new or replacement SCSI and floppy cables? its just being really weird.....

AIX 3.2 Weird Networking Problem

Double-Sided disk drives reading Single-Sided disks (HP 9122 vs 9121)

by jplist2007＠kiwigeek.com

Hey guys; This may, or may not, be a silly question, but in all my years of fiddling, I realised I had never tried this, so I'm unsure of what the results will be. My HP Logic Analyser (1630G) can talk to a HP 9121 via HP-IB. I have found a 9122, which is a double-sided version of the same device, as far as I can tell. I'm fairly confident the 1630G won't care - but the diskettes that I have (inverse assembler pack, thanks Gavin - you rock) are single-sided. Is there any reason that the 9122 DS drive won't read a SS diskette for the 9121? Thank you for your help! - JP

Line time clock wanted for PDP-11

by steve＠cosam.org

Hi all, I'm looking for a KW11-L line time clock (that's the M787) for a PDP-11. I don't suppose anyone happens to have one lying around they'd be willing to part with for a reasonable sum or maybe trade for other DEC stuff? A KE11-F floating point module (M7239) would also be a welcome addition, although I suspect there's much less chance anyone has one of those going spare ;-) Cheers, -- Steve Maddison http://www.cosam.org/

RetroGraphics VT-100 or not?

Can someone confirm or deny that the following two photos: <http://www.xmission.com/~legalize/tmp/1.jpg> <http://www.xmission.com/~legalize/tmp/2.jpg> depict a retrographics upgraded VT-100? This seller previously sold a number of retrographics VT-100s on ebay that were badged as such, but this one lacks the retrographics badge on the exterior of the case.

I'm fairly confident the 1630G won't care [...] Unfortunately, the HP9121 and HP9122 are very different. The former uses the Amigo protocol to communicate with the host while the HP9122 uses the more recent SS-80 protocol. If the 1630G can use both protocols you are OK, otherwise you're stuck. The HP-85 had an optional ROM that allowed use of SS-80 drives, perhaps there is a firmware update for the 1630G that talks SS-80. Regards **vp

9 track tape drive motors - suitable for a go-kart?

by sellam＠vintagetech.com

Brad, I suggest a much better use: turn it into a windmill. I finally got my hands on a motor from a 9-track I scrapped. It puts out several amps at 24V+ when I hand-spin it. It will do nicely as a current source to charge a lead-acid battery, especially where I live: http://en.wikipedia.org/wiki/Altamont_Pass_Wind_Farm As Tony already mentioned, it won't have enough power output to be good for a go-kart. -- 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 ]

9 track tape drive motors - suitable for a go-kart?

by brad＠heeltoe.com

This has only a little to do with classic computing, but it seems like it could generate epic amounts of email, so what the heck... Does anything know much about the construction and capacity of a typical 9 track tape drive motor? Like the big 1 foot x 6" tubes which I've seen a kennedy or DEC drive? I don't know anything about how they are constructed, but I assume they are high RPM and high torque. And probably some sort of DC stepper. I have a racing go-kart frame which is currently missing a motor (a CRG if anyone cares). It occurred to me that it might be fun to grab a large number of high capacity batteries and somehow rig one of the tape drive motors to the live axle. I assume via a reduction gear and chain. (clearly math needs to be done, but I want to start by finding the right motor) I would imagine several versions, starting with the simplest version but moving to something where both rear wheels are driven and having some sort of "software differential" and the moral equivalent of compression braking. no doubt there is something like alt.cars.electric-karts where I should go with this, but I thought i'd ask about the tape drive motors first. Anyone know what their specs are approximately and if they would be appropriate? (my goal is to be able to smoke the rear wheels and then turn on the traction control :-) clearly I've been spending too much time on the Tesla and Spacex web sites :-) -brad

Altos Computers near Seattle WA

I just bought up a large lot of vintage stuff and found 3 Altos computers in the lot. Not exactly my cup of tea for collecting but I know someone out there will be interested in these They appear in good shape overall (no broken pieces or anything). I hate eBay so thought I would post these here. I would prefer local pickup but I'm happy to ship too (they aren't that big). I'm taking offers for one or all.

Computer collectors are no longer the dweebiest people in the world...

by James＠jdfogg.com

> > I find almost anything old to be interesting. Lately I've been looking > > at old vacuum tube intercoms (the kind with art deco cases). > > What make? I'll bet I have manuals for some of that stuff... I like Rauland and Bogen, the Bakelite years. I'm watching eBay to see what comes up. Lately I'm spending a lot of time in the barn with some new horses and goats. I don't want to run a PBX extension to the barn, but an intercom is appealing. A lightning strike on a PBX extension would ruin my day. A tube type intercom is more likely to survive, especially a wireless one (carrier current I think is what they called that wireless method using power lines). Also, an intercom would let me monitor audio in the barn to see if everyone is getting along well in my absence. My other choice is a pair of VoIP capable routers and an 802.11 wireless bridge in the barn. I'll use the routers in an OPX configuration to the PBX.

MIT want to make $12 Apple II clone

by sellam＠vintagetech.com

A few (worthless) comments: 1) I agree with Eric Smith for the most part. 2) This will FAIL. 3) As Eric said, it's a cool idea for us retro-dorks, but for real people they will wonder why someone bothered to hand them a cheezy video game console for $12 that they earned working for four cents an hour from 6am until midnight seven days a week for eight years. 4) The title of this thread is dumb, but at least it's lame. 5) If Nicolas Negroponte (brother of John Negroponte, war criminal) finally gets his act together and is actually able to produce the OLPC for $100 then it would render this $12 thing a dumb joke. The OLPC is a real computer. I've used one. It is made from the element Awesome (symbol Aw).

7) Right said Fred: "There exist non-infringing copies of the Apple ][ firmware - Basis, Franklin, and Laser128?" - I had the same idea...use the Franklin 1000 ROMs because they are legal and I doubt there is anyone left from Franklin to go after you. 8) Chuck Guzis made the most sensible suggestion I've heard in this entire thread: "I'd humbly suggest that they simply market a keyboard and mouse that interfaces with a mobile phone. There should be more than enough compute power there--and you get connectivity as a side benefit." It's genius in its simplicity.

MicroVAX 4000-105 Fast Wide Differential option?

by binarydinosaurs＠gmail.com

Folks, Today I came across an oddity, a standard ds-47dbm-b9 VAX 4000-105A but seemingly featuring a third-party FWD/DSSI/SCSI option. Instead of the usual angled rear connector box containing 2 DSSI busses and a SCSI-1 connector the machine had a rectangular breakout box that featured from top to bottom FWD SCSI (68pin), blank, DSSI (single port), SCSI-1. The FWD port was connected to a Baydel RAIDER5 raid system and also had a differential terminator. I'm pretty sure that wasn't a DEC option in the UK, 2 DEC resellers I know agree so has anyone else heard of this? I wasn't allowed to shut the machine down so I couldn't check for manufacturers or part numbers..... VMS designator for the drive was DKW100 which further points at it being wide SCSI.... cheers! -- -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest home computer collection? www.binarydinosaurs.co.uk

Vintage sun stuff free for collection in south bay area.

by silvercreekvalley＠yahoo.com

Hi Sorry for the short notice on this... I have various vintage Sun items available for collection following a storage clear out. No charge for the items, but collector must take everything as I wont have time to split or arrange for multiple pickups. *Various parts for a Sun 3/80 including case, motherboard, possibly floppy drive, and more parts (can confirm). *Sun 3/60 fitted with colour framebuffer. *Sun 2/120 deskside unit. This is the deskside Sun 2 case with internal PSU and multibus card frame. The original multibus cards have been removed and I am unable to find them. There is no keyboard. *Sun monitor (mono) *Various other computer related parts including an old acoustic coupler modem and phone and a motherboard from an old Sun server (VME bus I think). All these items are untested and for parts only - that is you should assume nothing works. Now for the bad news .. unfortunately these items need to be collected by Friday 8th August ie. this week so would suit someone in the bay area (CA). Contact me off list if interested. Cheers Ian.

Please contact me off-list. Last weekend I came across a(n) SGI Indigo2 and several Indys at the local university surplus store. Having no experience with SGI gear I couldn't resist and picked up the Indigo2 and (x2) Indys. The prices were quite reasonable, and now I know why! There are no drives inside. As a rule, all systems from this outlet are stripped of their drives before being put on sale. If only I'd known. This particular surplus store always binds the machines closed with nylon shipping straps to prevent people from delving inside and lifting little parts without paying for the machine. So I couldn't 'pop the lid' and check them out. And, you can't cut them open until you buy. What is the saying?..."What you don't know can't hurt you," or something like that? ;) My ignorance of SGI gear and the store's policy cost me on this one. Live and learn! Anyway, I now have an Indigo2 (pre-IMPACT! green case) with what I think is 256MB RAM, and 2 identical Indys with R4600/133 CPUs and mabye 128MB RAM, all without disks. I'll know more when I get a 13W3-to-VGA cable rigged up. Anyway, hoping to resurrect them with some flavor of BSD, or even IRIX 5.3 if I can find it. Thanks, Jared

HP 5036A microprocessor lab - searching for copy of "Practical Microprocessors"

by simon_coleby＠agilent.com

Hi Stuart, This is a long shot, but here goes... I have an HP5036A lab, but lack the book. Searching, I found this on a forum from way back in 2003: "Yes, I managed to get a manual, by watching auctions on eBay. In fact, I bought another HP 5036A plus manual and let the seller keep the hardware to save shipping costs from England to the US. The manual is softcover and would not be easy to copy without cutting the spine off, which would ruin its value. Don't give up, though. I know someone that has a manual that has been cut up and copied and I'm trying to get it so that I can make an Acrobat PDF file of it. Stuart Johnson" I don't suppose you ever got a .pdf copy scanned? Just interested. Cheers, Simon Coleby Customer Service Centre.

For example, my Z80-based Altos 8000 > has a bank-switching MMU that could operate the same way as an MMU on a > 808[68] would. Actually, some PDP-11 models do support restartable instructions. Just not all of them. It requires the MMR3 register, which tells what modifications have been done to different registers before the instruction was aborted, so that you can back out of that, and then restart the instruction. Some PDP-11 models' MMU would also allow you to implement a virtual memory system, if you wanted to. It's just that noone did, and perhaps for good reasons. With only 8 pages, and way more physical memory than virtual, there isn't really much point in implementing a virtual memory system. But on an 11/70, it is definitely doable. Another example of the hardware designers implementing something that they didn't know was needed, but which could be done without much extra effort, so they did it, just in case someone would want to play around with it. But I think we've already established that the PDP-11 isn't brain damaged. :-) (Oh, and I agree with Tony Duells sentiment about the Intel brain damage. It's plain and simple just a question of not doing something one way when it was common knowledge at the time that that was the way to do it. NIH or just sheer lack of clues don't matter. It's brain dead all the same.) Johnny

Free PDP-11 Stuff in Bedford, NH

by dbetz＠xlisper.com

I have a "PDP-11" that is actually a box (BA-23) that used to contain a MicroVAX I. I replaced the MVI boards with the following modules: M8190 KDJ11-B M7551-CF 4MB memory M7504 ethernet adapter M7555 RQDX3 hard/floppy controller M8043 DLV11-J 4 line serial It also contains the following drives: RX50 two 5.25" floppy drives RD54 159MB hard drive It seems to work. I was able to get RT-11 installed on the hard drive and the system boots to a prompt. I haven't played with it much since then though. I also have a bunch of other Q-Bus modules including a KDF11 CPU and some other memory and I/O boards as well as a few spare drives. Is anyone interested in coming to pick this stuff up? David

Faceplate or floor stand for DS20E

by bob＠jfcl.com

I got one of Guy's AlphaServers - it's actually a rack mounted DS20E that's working fine (thanks, Guy) but unfortunately all of them were missing their faceplates. I know it's a long shot, but does anybody have a faceplate for a DS20/DS20E, or better yet a set of the floor pedestal skins, that they'd part with? Thanks, Bob Armstrong

Offer: Mac Color Classic box

by silent700＠gmail.com

That's right, just the box - the cardboard kind. This one's for the hardcore MacHeads out there. I've got a CC, which I'm keeping, and never had any packing materials, books, etc., but somehow I ended up with the box. It's in reasonably good shape, with various shipping/store labels on it, but not torn or stained. If anyone wants it, I can flatten it, put a label on it and send it USPS or whatever your favorite carrier is. Otherwise, out it goes... j -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org

Free HP 85B and accessories

by dbetz＠xlisper.com

I purchased an HP85B and a few accessories a while back and I've now come to the conclusion that I am not going to have enough time to do anything with it. I've verified that the HP85B itself works except for the tape drive. It has the sticky capstan problem and will need to be repaired. The printer seems to work though. The collection includes the following: HP85B ROM drawer 82936A with the following ROMs: - plotter/printer 00085-15002 - matrix 00085-15004 - advanced programming 00085-15005 I also have the following modules: HP-IB Interface 82937A Opt 001 Serial Interface 82939A 128K Memory Module 82909A Of course, it would be great to trade this equipment for something interesting. At the moment, I'm more interested in music synthesizers than in classic computers. I don't really expect anyone on this list to offer that sort of trade but if you just happen to have some old music stuff laying around that you don't want, I'd love to hear about it. In any case, I don't really want to pack this stuff up. I live in Bedford, NH and would be happy to give this equipment to someone who is willing to come here and pick it up. David

Can anyone identify this 9-track drive?

by derschjo＠msu.edu

I picked up an old 9-track drive and thus far I've been unable to identify what, precisely, it is. I have a couple of pictures at: http://yahozna.dyndns.org/scratch/9-track It has no manufacturer or brand information on it other than an "Interface Data, Inc." label on the front and a label on the back indicating that it is Model No. 9946. I can't find any information at all on the 'net going by this information. I'm guessing that it's a rebranded drive. It is a desktop unit, horizontally mounted and self-threading. As far as I can tell from examining it and fooling around with the front panel buttons it has a SCSI interface and does 1600 and 3200bpi. In the back of the unit are 5 slots, 4 of which are filled with cards. It appears to power up fine, but I can't get it to show up on the SCSI bus when hooked to a PC -- I don't know if the interface is broken or if there's some configuration I need to do. Any ideas? I'd like to find a manual for it so I can figure out what it can do and how to configure it. Thanks as always, Josh

HK ET-1000 Trainer

by silent700＠gmail.com

Looking for some advice on the ET-1000. I think Heath trainers were discussed here not too long ago. I have an opportunity to buy one locally for what I think is a fair price. While it would be nice to own as a relic, I'd like to actually use it as well (I intend to begin an electronics curriculum in the Fall.) It seems to have the features I'd need, and I'm assured it's working properly, but is too vintage to use regularly? Would I be better off just going with some Rat Shack kit? Thanks to all -- j

Floppy controller Q - VCO Inhibit / VCO Sync, and IBM format

by ajp166＠bellatlantic.net

The 765 does the skip of index gap thing regardless of VCO connection an that is triggeerd off the index pulse. VCO inhibit is there to prevent the PLL from trying to track the the mistiming an index gap can introduce. Not always required and some VCO designs are better behaved.

AIX 3.2 Weird Networking Problem

by devonstopps＠gmail.com

Hi All, I've run into a problem with TCP/IP on AIX 3.2, hopefully someone can shed some light on this weird problem. I've used smit to configure the network - which works fine within the subnet. The gateway points at the building router (x.x.132.1), and, a netstat -rn returns this on the default route as well. But, no traffic gets out of the building. A traceroute shows the first hop is made to x.x.132.63, where it dies - a seemingly random PC, which is not in any configuration file on the system. Any ideas why this might happen? T.H.x. Devon
