Infoserver SCSI chips?

by witchy＠binarydinosaurs.co.uk

Hi folks, Had a mail from someone wanting to know which SCSI chip is used in the Infoserver 150.

MK11 box controller, or M8159 board schematics

by julesrichardsonuk＠yahoo.co.uk

Was fiddling with our Decsystem 570 this weekend. Seems like we may have a PSU fault as the left-hand M8728 MOS memory boards in the crate don't have a lit green LED on the top, whilst the right-hand boards do. Tried the obvious swapping memory boards around and the associated A/B control boards with no luck, and according to the bitsavers docs a problem with PSU B would knock out that portion of the memory crate's bus. Anyway, I'm looking for either the schematics for either the MK11 box controller, or for the M8159 data buffer board. In particular I need the pin connection diagram for the 40 pin ribbon cable that runs between the box controller and the M8159 board. Our Decsystem 570 never had a box controller; instead it had someone's homebrew attempt at half a box controller - a bunch of LEDs on a single- width board plugged into slot 26/F of the memory crate, and a couple of SPDT switches grafted onto the edge of the M8159 board (yuck!). Slot 26 in the MK11 appears to be a spare; someone's added wires beneath to connect three of the LEDs back to the power supplies, so I know those are doing the equivalent of the battery status LEDs in a real box controller. However, there's three more LEDs on the homebrew board that are soldered directly to various pins on the box controller connector of the M8159, and the two bodged switches are connected up to pins here too. The two switches are unlabelled, so knowing the pinouts of the box controller connector is the only way of working out what they do. Working out what the three unknown and unmarked LEDs are for would be handy too! The manual for the MK11 doesn't go into detail of connector wiring though - any have the relevant schematics? cheers!

Cleaning gungy Flexowriter

by rigdonj＠cfl.rr.com

I asked about cleaning up the Flexowriters and a friend of mine reminded me that the old typewriter shops had vats of solvent that they would dunk the entire assembly into (taking off electrical and rubber parts before-hand). These are pretty nasty so I thought that sounding like a good idea. I was thinking of using minerals spirits. Anybody have any experience with using that on electromechanical stuff? Any sugggestions? I thought I'd remove the platen and belt on the RH side and any other rubber parts that I could see. Does anyone know if there are any parts inside the Flexowriters that should be removed first? Joe

question about pdp8/e console switches behaviour

by GOOI＠oce.nl

Hi All, after some distraction on other projects I picked up my pdp8/e simulator that runs on the 6809 Core Board. When I stopped a few months ago, I got the simulator working (as far as I can know with my very limited pdp8/e knowledge), but the console (yes, blinkenlights!) crashed the software. That problem is fixed, but what I can not get clear from the books is the active position of the HALT and SING-STEP switches. When the Switch Register switches are "down" they produce a logic zero; the "up" position present logic ones. Likewise for the SW switch. The momentary switches CLEAR, CONT, and EXAM are "up" in their normal position, but in that 'block' are also two switches: HALT and SING-STEP. Are these two active in the "up" or the "down" position? TIA, - Henk, PA8PDP.

Kickass "terminal" find:

by toresbe＠ifi.uio.no

Allright, my grandma called me telling me she saw something I might like at a fleemarket. Thinking it would probably a typewriter or an SVGA screen, I still wanted to stop by the fleemarket. I was wrong. It's a big, blue, keyboard-folds-down Atlantic Research Corporation Interview Comstate I. This is one of the coolest pieces of equipment I've ever seen. Anyways, it's got a program bank. Are there any other programs availible out there? It can function as a 1200bps terminal, and it does. Anyone know anything about it? TIA, -- Tore S Bekkedal <toresbe(a)ifi.uio.no>

demodulating audio cassette wav files

by cswiger＠widomaker.com

Gang - Any tips/pointers appreciated. I have some cassette tape audio files using 300 baud 8/n/1 format simple fsk 1200/2400Hz I think. Same audio you would find on a cassette tape for program storage except in a wav file. Any easy way to demodulate it back into data? Something like a software (mo)dem that can read the audio file and create the contents? Otherwise I will have to type the program in again (yuck) or read it into the old machine and rig up a serial interface to transfer it to a new PC running a simulator (more fun but would rather just extract it directly). Thanks --Chuck

Flexowriter: Round 2!

by rigdonj＠cfl.rr.com

Today I started working on the 2nd Flexowriter. First I should point out that this is a newer machine than the first one. This one has an ~13,500 serial number and the first one has an ~4,000 serial number. This is what it looked like to begin with; front <http://www.classiccmp.org/hp/flexo2/2front.jpg> and back <http://www.classiccmp.org/hp/flexo2/2back.jp.g> and right hand side <http://www.classiccmp.org/hp/flexo2/2right.jpg>. At least the keyboard hasn't been smashed in this one but you can tell that it hasn't been used in a LONG time by the mildew on the keys. The keys are supposed to be black and not white! The power cords of both machines had been wrapped around the carriage for so long that they had taken a permanent set and they broke when I tried to unwrap them! The first thing that you notice about this machine is that all the removeable covers are dark blue instead of brown. I've been told that sometime in the 60s they changed the machine color from brown to blue. Perhaps this is a transistion model or maybe somebody just mixed up the parts during a repair or modification. This is the same model as the first one but it's very different. For one thing it has a transformer in it <http://www.classiccmp.org/hp/flexo2/2motor.jpg>. It also has a 2nd circuit board lurking behind the transformer and the fuse holders are very different from the first machine. But in the back it's even more changed. There are a lot more relays in it and the relays have a lot more contacts. <http://www.classiccmp.org/hp/flexo2/2relays.jpg>. The blue arrows show all the new relays and the red arrow shows a stepping relay that has also been added to this machine. This appears to be a factory modification since all the brackets, wiring, etc fit perfectly. However all the added parts use wire with grey plastic insulation instead of the various colored cloth covered wire used originaly so this appears to have been done long after the machine was originally built. This mod also uses a different type connector (white arrow). In addition to the added relays, the encoder <http://www.classiccmp.org/hp/flexo2/2encoder.jpg> has three more switch levers added (red arrows) to the original seven levers (blue arrows. And of course there are three added sets of switch contacts (red arrows) on the back of the plate that hold the original seven sets (blue arrows) <http://www.classiccmp.org/hp/flexo2/2switches.jpg>. All of the added electrical parts use the same grey plastic insulated wires. Another change that I spotted was the use of round rubber feet with studs sticking out of the top and bottom of it (the one in the picture is broken). The top stud screws into the machine to mount the foot but I don't know for sure what the bottom stud was supposed to screw into.* The first machine used square rubber feet that were obviously make to sit on a flat surface such as a table top. Both of these machines were built by Commercial Controls Corporation prior to it being taken over by Frieden in the early '60s. <http://www.classiccmp.org/hp/flexo2/CC.jpg>. FWIW Here is also a picture of the PT punch <http://www.classiccmp.org/hp/flexo2/2punch.jpg>. It's a modular design and I had to take it off to remove the encoder. *When I was a kid my dad had several teletype machines. A year of two ago he told me about another machine that he used to have that printed form letters from a paper tape. He said that it stopped printing at certain points and you could manually type in people's names, addresses, etc. He got rid of the machine many years ago and didn't remember the name on it. Today I called him and asked him about it and asked if it was a Fleowriter and he said that it was. He said that he still has a few accessories for it including a bit bucket and a Frieden marked dust cover. He also said that his Flexowriter sat on it's own stand. I suppose that that is what the rubber feet with studs on this machine are intended for. As I mentioned. I worked on the second machine today. I found that there's something locking up the carriage and preventing it from going back to the left. The release buttons have no effect even though all the linkage is free and moves like it should. The problem seems to be in something UNDER the carriage. I finally found a escapement behind the carriage and I pryed over the lever that prevents it from turning backwards and I was able to move the carriage to the left. I need to find out more about the escapement and what how it's supposed to work. The shafts in the encoder <http://www.classiccmp.org/hp/flexo2/2encoder.jpg> that rotate and move the switch levers were also rusted up. I had to take the encover out and take it apart and clean the pivots before it worked. Boy getting it all back together was fun! NOT! Joe

Xerox 6060

by jrice54＠vzavenue.net

Any one know anything about a Xerox 6060. I've got a free one to pickup tomorrow and I'm wondering what it is and is it worth the effort. It's set up with a 10/10 Bernoulli box too. There doesn't seem to be much on Google about it as Xerox also uses 6060 as the model number of a large digital printing press.

Ok - I've figured just about everything out! ... The board on top is an 80 column adapter. The Boot rom listings are in the technical manual (duh!) The problem with this Osborne is the keyboard! - It is apparently sending a false key, which is causing the O1 to clear/redraw the screen. Unfortunately, the keyboard does not look very servicable ... anyone successfully fixed one of these things? (membrane matrix).

Another Osborne needing TLC

by dave04a＠dunfield.com

After the 1A monitor started working, I turned my attention to another Osborne in need of attention. This is an Osborne-1 - the older one in a "tan" colored case - not a 1A. This machine "sort of" works - it powers up, beeps, and displays the "box" on the screen, along with the "Insert disk in drive A and press RETURN" message. At this point however, it seems to keep restarting - the screen continually clears and redraws the box/message, which creates a flickering effect. It does not beep as it restarts - experimentation shows that the beep is enabled at power-up and gets turned OFF by the firmware as part of the init sequence - it appears the the firmware does not actually turn the beeper ON at startup, just OFF, so it only beeps after the first power-on (?) Took it apart and checked all contacts/connections/sockets for corrosion, reseated everything and still the same operation. A couple of questions: 1) This machines has a large board on top of the mainboard - this board plugs into the Z80 socket (the Z80 moves to the top board), as well as a ROM socket and the monitor connector - there is also a bunch of "flying leads" which connect to various points on the mainboard and attach to a socket/header on the top board... Can anyone tell me what this board is? Is it "normal" on an Osborne-1? Neither of my 1A's have this board, and the mainboard appears to be the same... Is it perhaps an upgrade of some kind? 2) Has anyone disassembled or otherwise obtained source code to the Osborne boot ROM - I would like to try and figure out how far the machine is getting, and what it is doing when it restarts. 3) Has anyone seen this behaviour in an Osborne before?

Osborne monitor service information ?

by dave04a＠dunfield.com

Hi Tony, >I would start by tracing the horizontal drive signal. My guess (without >seeing it) is that the 555 is part of the vertical circuit and can be >ignored for the moment. You may find the horizontal drive signal goes to >the base of the drive transsitor, transformer coupled to the base of the >horizontal output transistor, thence to the flyback. Thats pretty much exactly the circuit --- This monitor is not designed to be very easy to work on - there's a metal plate right under the circuit board, and the other side of the board is right up against the neck of the CRT - makes it pretty hard to take measurements in circuit. This afternoon, I pulled it all apart, checked continuity through the flyback, and pulled the horizontal drive transistor and checked it - it appeared to still be a transistor (correct "diode" junctions from both B-C and B-E). So - I put it back together, planning to leave it for another day - on a whim I tried it, and it worked! - And I used it for a couple of hours as I checked out the rest of the machine with no further problems. I still have no idea what the problem was - perhaps a bad contact in one of the connectors, although I wiggled and jiggled everthing and was unable to deter the monitor for working perfectly after I put it back together.

Osborne monitor service information ?

by dave04a＠dunfield.com

Hi Guys, I have an Osborne-1 with a bad monitor - I have the technical manual, which gives schematics for the main logic board and the disk board, but NOT the monitor. The monitor is a: Zenith model DS5NF3 Symptoms are: Its Powered through a single +12v line on the connector, filiment lights, which suggests power is present. Horizontal drive, vertical drive and video signals are all present on the monitor connector. No light at all, no "buzz" typical of flyback transformer. Looks like horizontal/high-voltage circuit is dead. Unfortunately I have no schematic - At least the only IC on the board is a 555 - hopefully no unobtainium used in this one (unless it's the flyback :-( anyone got diagrams or other service information on a "Zenith DS5NF3" monitor. Suggestions/debug hints welcome - I'm guessing horizontal output transistor or flyback ... [and before anyone asks - yes, this is the one which was missing it's monitor plug, however I have borrowed the plug from a working machine and verified that the signals are getting to the monitor] Regards, Dave -- dave04a (at) Dave Dunfield dunfield (dot) Firmware development services & tools: www.dunfield.com com Vintage computing equipment collector. http://www.parse.com/~ddunfield/museum/index.html

LF: Obsorne-1 video jumper plug

by dave04a＠dunfield.com

Recently picked up an Osborne-1 which is missing it's video jumper plug - this is the small block to the right of the keyboard connector which enables the internal monitor, and is removed to connect an external monitor. I know I can make one - but I thought I'd check here to see if anyone has a "parts" or beyond-repair Osborne that might have a spare of the original jumper block. This is an Osborne-1A - the second edition, however I believe the jumper block is the same on both versions.

Flexowriter history

by rigdonj＠cfl.rr.com

Al pointed me to some information about the Flexowriter on Herb Johnson's website. It seems that the Flexowriters have been around since at least WW II and was orignally made by Commercial Controls. CC was bought out by Frieden sometime doing the 1960s. The original Flexowriter only had a PT reader and punch and no external I/O and was used for generating form letters. Notable, It was used by the US government to write letters to relatives who lost family members in WW-II. Later new models were created by adding interfaces and a 2nd punch and 2nd reader. The two machines that I have appear to be original Commercial Controls FL models without the external I/O interfaces. Oh, I'll throw in a bit more history about these two particular machines. These two originally came from the US Air Force Missile Test Range. Anybody remember what that was? It was the original name for what is now called Kennedy Space Center. Originally just called Cape Canaveral after the geographical feature, it was used as a missile test range starting in the late 1940s and was called US Air Force Missile Test Range. The name was changed to the US Air Force Eastern Test Range about 1959 when NASA choose it to be the site and their manned launches and it was renamed to Cape Kennedy after the death of President Kennedy in 1963. Footnote: Not many people realize it but the Cape Kennedy name was not officially recognized so the land is still Cape Canaveral but the facility was officially named Cape Kennedy in 1963 and is currently named the Kennedy Space Center. Another footnote: For many years I worked for Martin Marietta in Orlando Florida. The Orlando facility was originaly built in 1958. MMC chose Orlando due to it's location close to to the Missile Test Range at Cape Canaveral since they originally planned to buid the Pershing missiles here and test fire them from Cape Canaveral. Herb has a short interview with an X-Flexowriter repair/salesman posted on his site at <http://njcc.com/~hjohnson/s_flex.html>. For anyone that's interested. Joe

HP scanner: doubly on-topic!

by tomj＠wps.com

I just acquired an old (on-topic)(I think) HP 9195A flatbed scanner... because it has an ADF (Automatic Document Feed). Likely it's only 300dpi monochrome, but I want it only for mass-scanning of (on-topic) crufty docs. (I have a nice, newish flatbed 2**20 color, 2petapixel/inch scanner I paid nearly $20 for, 15 minutes ago, but it requires a hairy meat arm to feed it sheets.) I found & downloaded the sj121en1.exe driver, which is the most-recent version, for Win95. I don't have a Win95 machine (I actually own zero win/dos computers) but bought a loaded Dell P120 for such things. My questions are all obvious: * has anyone used this scanner on linux? (parallel interface, mind you) * does it work under wine, vmware, dosemu? * Will it work under WinXP? Win98? DOS? I do have legit Win95 CDRs to install, as a desparate last resort. Don't make me install it please!

That is not true. There are several Pentium4-based AGP, ISA, PCI based motherboards. I went a different route for my transputers which are ISA-based for the most part (I use an SBC Pentium4 with 8 ISA, and 12 PCI slots). The problem is that they are a bit expensive compared to a regular Pentium4 motherboard. The necessity is due to the tremendous amount of industrial equipment that needs to continue running on an ISA-based machine. Here is one: http://www.cyberresearch.com/store/product/776.2.htm (This one is on the expensive side, but I saw one for about $300)...

RML 380Z keyboards

by julesrichardsonuk＠yahoo.co.uk

Longest of long shots, but I don't suppose anyone has any spare RML 380Z keyboards that they don't want, do they? No, I didn't think so... Anyone know if the same keyboard unit (repackaged into a different shell or whatever) was ever used with any other machines / terminals of the time? A quick dismantling of mine shows that they were made my Alphameric, and that the PCB looks horribly familiar (as does the name!). cheers, Jules

more Flexowriter

by rigdonj＠cfl.rr.com

I've been cleaning and repairing the Flexowriter today. While I was working on it I took some pictures. Here they are. The first ones show it just the way that I got it. This <http://www.classiccmp.org/hp/flexo/front.jpg> is what it looked like when I got it. Here is a picture of the left side with the PT reader and punch <http://www.classiccmp.org/hp/flexo/punch-reader.jpg>. Here is a picture of the back showing the label <http://www.classiccmp.org/hp/flexo/label.jpg>. Right hand side <http://www.classiccmp.org/hp/flexo/right.jpg>. One of neat things about it is that it has a stand built into the back of it so that you can stand it up and work underneath it. Here is a picture of the stand <http://www.classiccmp.org/hp/flexo/stand.jpg>. It has two shafts that stick out of the back on the machine near the top and a shaft with two wheels that runs across the bottom. The wheels on the shaft are wood! OK enough of the "dirty" pictures. Here's some more after I cleaned it up a bit. Here's what the bottom looks like. Note that it's sitting up on the built-in stand. <http://www.classiccmp.org/hp/flexo/bottom.jpg>. Here are closeups of the motor and the two connectors coming from the PT Reader and Punch <http://www.classiccmp.org/hp/flexo/motor.jpg>. Here is a closeup of the PT punch with the cover removed, <http://www.classiccmp.org/hp/flexo/punch.jpg>. And here is a close up of the PT Reader with the cover removed, <http://www.classiccmp.org/hp/flexo/reader.jpg>. Another close up of the bottom showing the self tensioner for the carriage drive belt and AC terminal strip. The last picture shows the "stuff" on the RH side with the cover removed. The switches at the RH are used to generate the six bit character code. I believe the round deice in the center is the clutch for the carriage drive belt. It seems to be stuck ON at the moment. The belt in the picture is the one that drives the carriage left and right. I'm not sure what the electromagnet on the bottom left is for. The power switch is shown above the electromagnet. <http://www.classiccmp.org/hp/flexo/carriage%20clutch.jpg>. Joe

Big Iron available - Data General Eclipse - plus lots more smaller stuff

by classiccmp＠vintage-computer.com

I went by my local recycler yesterday on the hunt for some items and came away with a list of stuff that might interest folks here. The main item was a DG Eclipse system in two racks with tape drives and more. I didn't spend much time looking at it but can probably get more information if anyone wants it. I also have no idea what the price would be but I can guess that shipping would be the big consideration anyway. The same place had a bunch of smaller items as well including a very clean TRS-80 Mod 3 with a RS dustcover, a Kaypro II, a Franklin Ace 1000, a CoCo that looked like it had seen better days, what looked like an IBM PC Portable in its canvas bag, and a Compupro system with the main chassis and a dual 8" chassis as well (this was wrapped in a pallet and those were the items I could recognize. There's a few cubic yards of other stuff mixed in that may or may not be related.) There were also a good number of vintage terminals stacked about. Several ADM3as in both blue and beige in various states of decay. Most looked serviceable with a couple having a bit of screen rot. The couple I turned on worked. None had the switch covers. There was also a Hazeltine 1500 in nice shape except for the fact that the video was bad and some TeleVideo 925s and 950s that worked but needed TLC. Newer terminals (DEC and Wyse, mostly) were all over the place. There was at least one VT100 that was marked as dead but that looked like it had all of the (yellow) parts. If anyone wants more info on any of this I'll be happy to get what I can or to put you in touch with the shop.

Surviving UK Transputer systems...

by RMeenaks＠OLF.COM

The transputer CPU was made by INMOS (which was later bought out by SGS-Thompson which became ST-Microelectronics). However, there were several manufacturers of transputer equipment. Some of the popular ones are INMOS, Transtech, Niche, Parsytec, Sundance, and Parsys. See the specs page for a list of vendors. This is not complete at all and only contains vendors I have info on. What type of INMOS stuff do you have??? Thanks, Ram -----Original Message----- From: Joe R.

I looked at the data sheets on your website so that I would know that the parts and part numbers looked like. Does anyone other that INMOS and Thompson make these? I find lots of parallel computing equipment so there should be some transputer stuff in there too. I have found a lot of high speed parallel stuff with INMOS parts but I think it's older (early 80s) than the transputers. But the transputer stuff should show up one day.

Surviving UK Transputer systems...

by RMeenaks＠OLF.COM

A transputer is just like any other processor with memory, etc, etc. Except that it has two unique attributes: 1) Has communication links so that you can hook it up to other transputer nodes (or other peripherals). This allowed you to create a multiprocessor system with several nodes (seen transputer networks of 1024 nodes at one time). It was like LEGO for parallel processing. The technology that was designed for the transputer is now slowing creaping into modern processors. Not bad for a mid 80's processor.... 2) Has micro-coded scheduler which allows you to create multi-processes inside a single CPU. It supported two priorities in high and low. You could do parallel processing in assembly with this baby! This is all embedded inside the CPU core. Designed around the mid 80's and had an EOL (End-of-life) around the late 90's.

A new transputer toy....

by RMeenaks＠OLF.COM

Just picked up an IMSB300-1 on ebay. This is cool as now I can connect my transputer processors on the network and access them from any machine on the net. Brings new life to an old friend. After opening it up, much to my amusement, it is really an off-the-shelf package. It contains nothing but: 1 IMSB018 - standalone transputer board 1 IMSB019 - differential link convertor board 1 IMSB404 - T425-based Size-2 TRAM 1 IMSB431 - Ethernet TRAM and it boots off of a firmware that is on the IMSB018. That's basically it. Anyone know how to connect this to a B004/B008? It didn't come with any cables etc. The links are differential, so I guess I can just connect this to a differential tram, right??

Surviving UK Transputer systems...

by julesrichardsonuk＠yahoo.co.uk

Ram's message prompted me to post this, although it's been on my mind for a while. Does anyone know of any complete Transputer systems (i.e. several processors, cabinet, front-end control system etc.) from the '90's that still survive within the UK? I'd like to get one for the museum sometime as we don't have any transputer equipment at present, and it'd be nice to have one on display and running. My old uni used to have a 140 CPU one that was capable of doing some nice ray tracing, but I've been unable so far to find out if they still have it. I imagine it's long gone and either dismantled or scrapped. Seems like individual bits turn up all the time (although probably with a high price tag which doesn't exactly suit a museum!) but not any big systems. If anyone knows of any company that used to have anything that might stand a chance of still being complete and just shelved in storage anywhere, I could make some enquiries... cheersy-bye Jules -- The most secure computer in the world is one not connected to the internet.

The board is a Niche Technologies NT1000 Advanced Computing Platform. Never seen one, but that is what it is. Niche became absorbed somewhat by Transtech later on. So, some of their products were later manufactured by transtech. The NT1000 was re-named to something else by transtech, don't remember the name. I get back to you on that. Niche made several sun transputer boards. Martin Frank OAKES used to work there and when Niche got bought out, they formed K-Par Systems which designed software and some hardware as well. I talked to Martin a while back, very nice chap. Talk to him if you need more details. His website is: http://www.vine.co.uk/ Cheers.

That's what I thought. But wanted to make sure. The AUI port of the IMSB300 is actually an IMSB431 which used a 5V transiever, so I am assuming the transiver on the IMS300 needs to be 5V as well.

I would guess so. The differential links are just the result of feeding normal links through 'RS422' bufferes (26LS31 transmitter, 26LS32 receiver). If you don't hve the official Inmos converter TRAM (which is not really a TRAM as it doesn't contain a transputer IIRC), you can easily wire up said chips.

New finds: Some days you win, other days you WIN!

I have a Friden Flexowriter somewhere that I adapted for use with my Altair when I was a teenager. Herbach&Rademan Surplus out of Philadelphia used to sell them. They come with a huge box full of DTL electronics that provide some sort of telecomm interface. We found instructions in one of the Hobbyist magazines (Byte?) on how to connect that box to the Altair serial port. Later we found other instructions on how to eliminate the need for the box.

He finally got in the load of Intel Multibus manuals that I'd been waiting for. Went down there this morning and spend about 4 hours digging thru a pallet load of manuals. Found about 50 Multibus manuals. But only three different manuals. Yeah. About 15 copies of each one! While I was there, they were sorting out another load of OLD stuff that they'd just gotten. There was a lot of '40s, 50s and '60s electronics in it as well as a lot of typrewriters, checkwriters and mechanical adders. while I was there I went over and looked in the scrap basket where they were tossing out stuff and in the bottom I spotted something that said "Flexowriter". I really didn't want to have to pull out all the junk that had been thrown in on top of it but decided to find out more first. A quick call to Alex Knight (aren't cell phones great?) and he confirmed that I SHOULD dig it out. So into the basket I went. An hour later and I was the proud owner of not one but TWO Frieden Flexowriters! Anyone have a manual or more information about these? Also found some OLD modules that are marked Digital Logic Modules. They're made of black plastic and about 1 1/8 square and 1/4" thick and have ten pins on the bottom. The pins aren't round but are blade shaped like those used on Jones plugs. There's no name on them but they have a symbol of a capital R with the electrical symbol for a resistor superimposed on it. I think I remember seeing that symbol a long time ago but I can't remember who used it. Does anyone remember it. Joe

deadmedia.org

by tomj＠wps.com

All this talk of DNS makes me hungry. The Dead Media site (http://www.deadmedia.org) is in need of a new owner. I nominally ran it for a few years, cleaned it up somewhat, then I passed it on to a new volunteer last year who ultimately flaked on me. There is sits with no change for probably two years. If anyone is interested in reviving it, preferably on another host, let me know. It's mainly a bunch of text. I have low-quality perl scripts that actually generate the HTML, the content is in a trivially simple flat "database" easily converted to anything else. There's a lot of room for work in categorization and such. There is also a mailing list, somewhat cobwebby, that was on old smartlist software, archives are around somewhere, plus the last-used list of participants if you want to poke them all in their virtual ribs.

1mbit dram chips?

by waltje＠pdp11.nl

Hi all, See... now I remember why I should not dive into yet another restoration project (such as my AT). It only causes me to need even MORE stuff :) My system came with one of the last NEAT-based mainboard, which did support both the 1Mbit DRAM chips, as well as those funky "SIPP" modules. It had 2 banks of those chips installed, and, at the time, I also had two banks of SIPPs in it, for a total of 4MB. For some reason, the SIPPs have been pulled, so I am now looking for a bunch of either SIPP modules, and/or about 18 of the 1Mbit chips to "fill the board." A 80286-12 copro would be fun, too. If anyone has something laying around they'd part with, pse contact me off-list !

OT: exchange of DNS secondary service?

by tomj＠wps.com

I do realize this is largely off-topic (though it's on my net machine that supports vintage computing activities), but I cannot think of a better bunch of people to ask. Please reply off-list. I have a long-lived, well-placed and reliable machine on the net, turing.wps.com, and I'm looking to exchange secondary DNS service with someone outside the U.S. or on the East Coast. My server is in a secure, A/B powered telecomm colo in Seattle Washington, 600+ Mb/s to three ASNs. I have a lot of heavy DNS experience so when I foul up I do a really good job of it. I've got a half-dozen zones, all small, and would set up axfr's for you in exchange for me. This of course does not require me to have access to your machines, and vice-versa, we just set up bind config. Swap for like service, no money involved.

New finds: Some days you win, other days you WIN!

by rigdonj＠cfl.rr.com

I got a call yesterday from one of my steady sources. He finally got in the load of Intel Multibus manuals that I'd been waiting for. Went down there this morning and spend about 4 hours digging thru a pallet load of manuals. Found about 50 Multibus manuals. But only three different manuals. Yeah. About 15 copies of each one! While I was there, they were sorting out another load of OLD stuff that they'd just gotten. There was a lot of '40s, 50s and '60s electronics in it as well as a lot of typrewriters, checkwriters and mechanical adders. while I was there I went over and looked in the scrap basket where they were tossing out stuff and in the bottom I spotted something that said "Flexowriter". I really didn't want to have to pull out all the junk that had been thrown in on top of it but decided to find out more first. A quick call to Alex Knight (aren't cell phones great?) and he confirmed that I SHOULD dig it out. So into the basket I went. An hour later and I was the proud owner of not one but TWO Frieden Flexowriters! Anyone have a manual or more information about these? Also found some OLD modules that are marked Digital Logic Modules. They're made of black plastic and about 1 1/8 square and 1/4" thick and have ten pins on the bottom. The pins aren't round but are blade shaped like those used on Jones plugs. There's no name on them but they have a symbol of a capital R with the electrical symbol for a resistor superimposed on it. I think I remember seeing that symbol a long time ago but I can't remember who used it. Does anyone remember it. Joe

I used to have one like that, and I may even still have some SIPPs -- but they would be 256K SIPPs, which you probably don't want. However, you do realise that SIPPs and SIMMs of the same size (capacity) have exactly the same pinout? You could either tack pins onto SIMMs (I've seen it done) or fit a SIMM socket to the board, if the spacing between the SIPPs is standard. I may also have some 1MB DRAM. What pinout and config does your board need? -- Pete Peter Turnbull Network Manager University of York

"Old PC" emulation ?

by waltje＠pdp11.nl

Hi, While reading up on my old Minix stuff (I found a box full of my old Minix backup floppies a couple of weeks ago), I tried to install them onto a PC I, um, borrowed from my customer (I was in Oslo for the week, and was bored at nights ;-) but that would not install. Obviously, old system software does not necessarily have to run on the new, current (PC) systems. Which led me to consider the impact of this on being able to run the older PC software anytime in the future. Can one still install a QNX box, or a Minix box, or an OS/2 system? So.. what it boils down to is: is there any (serious) project on doing a "old pc systems" emulation a la SimH, which does, for example, a pure IBM PC, PC/XT or PC/AT ? Just some random thoughts...

Up For Grabs: HP 13037 and HP 7925 disk drive

by rigdonj＠cfl.rr.com

I spotted these in a scrap place today. I brought the 13037 home but the 7925 was too big to fit in the car. The 13037 looks like it's in perfect condition and I have the cables for it. I think this stuff orginally came with the HP 1000 that I found last week. At any rate, I have 13037 interface cards in the 1000 and I'm willing to part with them too. The 7925 appears to be complete and in good condition. However it was dropped off of a truck and may be damaged internally. I don't know if the heads and spindle were locked or not. I have no way to haul or ship the 7925 so don't ask. It's located in central Florida so plan on coming and getting it if you want it. Anyone intersted in the 7925 needs to let me know ASAP so that I can make sure that it doesn't get torn apart for the gold scrap and aluminium. Best offer or trade me something that I can't live without :-) Joe PS it looks like these have the MAC interface.

facit n4000 service manual?

by jwest＠classiccmp.org

My facit N4000 reader/punch has developed a problem. Would anyone have a service manual for this unit? I have the operators guide but no service manual. When powering up the unit, about 20% of the time it comes on with "Err" in the display. If I turn it on and off a few times, it comes up correctly with "Off" in the display. Also, the test tape created in diag test #4 mostly, but not always, passes it's read in diag test#5. Can anyone help with a loan of the service manual or perhaps some advice? Regards, Jay West

Ok, I am replacing the HP terminal with either a Macintosh SE or an Apple IIc+... Environment = Linux running simh pdp11 running RSTS/E V7.0 (with telnet from all my other machines) Has to sit in a 2" x 2" square area on my desk, although I think all three choices overflow the intended area. Please weigh in on the following three scenarios: Door #1 - Macintosh SE - Have an appletalk laser printer for this machine - perhaps smaller footprint. Door #2 - AppleIIc+ - Imagewriter instead of a laser printer if any printer at all. - Coolness factor (8 on a scale of 1 to 10) 10 would be a real DEC terminal.. - No Terminal software at hand.. (would beg someone to send me a diskette) Door #3 - HP Terminal - already and still hooked up, and works ok... but. - it's not *also* a computer that I want to get back on display.

new find: another HP 1000!

by rigdonj＠cfl.rr.com

I finally checked out the HP 1000. It seems to work. I checked and the CPU section has a DCPC card, Memory Protect Bd, Mem Bd, four 256KW memory cards and a 2102E Memory Controller. The IO side is full of cards. Here's the list: I/O Buffer, I/O Buffer, 12966A BACI Bd, 13183 7970 Mag Tape 2, 13183 7970 Mag Tape 1, 26099A Line Printer, 26099A Line Printer, Bus I/O, 12966A BACI Bd, 12966A BACI Bd, 13037 Intface, 12821A Disk Intface, Time Base Gen, FEM. It seems to be quite a nice machine. Joe I went to one of my favorite scrap sources today but I was just there a few days ago so I didn't expect to find anything. But I was wrong! I found a NICE F series HP 1000 along with the Floating Point Unit. I haven't looked at it closely yet but all the card slots are full and it's in very good condition. It was mounted in a short (desk height) HP cabinet marked "HP 1000 System" along the top. Unfortunately I had to leave the cabinet, it was just too big and heavy fit in the vehicle that I was in. I'll go through the computer later and give a full list of all the stuff in it. Joe

>In the meantime, I've used my portable Cybiko as an eBook reader, and a few >other trivial tasks. I know this is going off topic, but how well does it work as an eBook reader? I'm looking for something fairly portable for ebooks. I have stacks of books and manuals in either HTML, Text, CHM (crappy HTML), or PDF format. And I haven't read them all yet because currently my computer is the best place to read them, which conflicts with me getting most of my reading done on the crapper. So I either need some portable unit to start reading ebooks, or I have to install a computer in my bathroom... humm... no for the sake of my marriage, I'd better just go with a portable unit. I've used my Palm for the text files, but the formatted HTML, and CHM files don't work so well on that small of a screen. And my Palm can't handle PDF. Is the Cybiko any better of a screen then a Palm? Can it do anything beyond plain text? -chris <http://www.mythtech.net>

URGENT - Big IBM Iron rescue - System/38, Ohio

by mross666＠hotmail.com

(CC'd to a couple of System/38-seekers I know of...) Hope someone can jump on this... a guy has to dispose of a complete System/38 setup, believed working - by the weekend. Miamisburg, Ohio. The unit has to be cleared by Monday of next week. He wants an arrangement in place by Wednesday, but the actual removal can wait as late as the weekend - so long as the collector is 'damn sure' he WILL turn up as promised! He tried the stuff on ebay at too-high prices, got no bidders - but at least you can see the pics (System, disk, tape, printer): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5134099178 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5134099696 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5134100141 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5134100797 Someone needs to move *fast* on this - contact the guy immediately. If no-one steps up to the plate, at minimum I'll try to get him to remove the boards from the /38, so I have a spare set for mine. Contact is Mitch - email miller(a)keyways.com or call him - 937-902-8392 I'd appreciate it if anyone is seriously interested, let me know too. The guy will want some money; he has an offer for the whole lot from a scrapyard, and they'll take it away if we don't. Good luck. Mike http://www.corestore.org

classiccmp hardware

by jwest＠classiccmp.org

All the hardware is finally in for the mirroring setup. I was going to go with software raid till I found out that the system won't boot when the primary drive fails (ie it won't automatically boot from the 2nd drive). So I went the hardware raid direction. The new hardware includes a 3ware Escalade 7006-2 controller ($123.70), and two 160gb PATA 7200rpm 8mb cache drives ($88.54 and $67.22, respectively). Total hardware expenditure including sales tax and shipping was $279.46. Of course, I'll take the time to reinstall from scratch rather than just copy the existing drive. So we'll be getting newer versions of freebsd, sendmail, mailman, mysql, php, etc. etc. etc. My intent is to throw the drives into a small test system and put that at the datacenter and configure/install everything remotely. Then when it's time to switchover, I should be able to just move the drives (and controller) from one system to the other and come back up. Then I'll start the process of migrating historical data from one to the other (by putting the old drive into the test machine). I'll give the list a big heads up when I get around to scheduling this. After this upgrade is done, I will be looking for volunteers (web design people) to see about giving the classiccmp site a facelift, possibly adding some new features, and (finally) cleaning up the archives.

It has just occurred to me that LA is only 3 hours away...Road Trip! :^)

Heath EC-1 on eBay

by dwight.elvey＠amd.com

Hi John Now there are two on ebay. The latest one is a little more on the conservative side. Starting at $990 with a buy it now price of $1250. I don't recall ever seeing one of these go for more than about $600. The first one does come with the plastic component holders. I wish I could find these today. They were actually half of the 300 ohm TV twin lead connectors. RS used to have them but has stopped carrying them. I've found that the miniature banana connectors from Pomona also work but they are expensive. I like the comment that one can not use the EC-1 without the operation manual, that the second fellow states. That is like saying that a person can't use a car without the operators manual. I guess that is an indication of the state of knowledge now days.

Intel MDS Further Information

Hi Scott This is a Series II machine, not a Series I ( no such thing as a Series I ). The IPC card is the indicator. That was only used in the Series II's and Series III machines. The Chassis should also have a non-multibus card called the IOC card that runs the terminal and the SD controller. The IPC card is the main processor card. It is the one that runs any code that you'd normally run from the disk. Also, you should note that there is an small interconnect for the aux bus connector that goes between the two disk controller cards. This may be bolted to the frame but it need to be there for the cards to work.

Hi I knew one of the fellows that wrote the 3000 code for the double density controller. A fellow named Lou Bolardo. It always astounded me that it took 2 boards to do a disk controller.

Hi The controller boards for DD were not that hard to talk too. The fact that they used the 3000 series had little effect on the main bus interface.

it works just fine and I just cut and pasted it from browsing just before I sent the message. I also just cut and pasted the link just a moment ago that I gave out and it works fine. Try going just to www.Intel.com - if you can't get there it could be a Florida issue (I am in Virginia). Every once in awhile, the lines appear to go down that connect the US together. If the browser said it was trying to open the site then the DNS server supplied an IP address to your browser and there is a line issue to the west coast. If it said it was trying to find the site, then you were not able to get to the DNS server to translate the name to an IP address and your connection to the DNS server is in question.

cp/m box for software

by emu＠ecubics.com

Hi all, did a little work on cp/m in the good old days, and thinking about getting at least one machine up again. As it would be mostly for having fun with the z80 again (or 8085, z180, z280?), I'm probably not interested too much in having any of the collector grade machines. So, the question is, what is the best cp/m machine for playing with the software ? cheers & thanks

HP 7900A on ebay

Search Ebay for "7900A" and you'll find it. Missing front screen. There was a day when I'd give most anything for one of these. Now I have a good supply so I thought I'd mention it in case anyone needed one. Anyways... the 7900A is one of the few HP drives that doesn't use a sector surface, it uses a glass reticule. If someone gets this drive and it needs work, let me know as I do have all the service manuals. More importantly, the 7900A is supported on most versions of TimeShared BASIC, including the "E" version which only needs one cpu. Regards, Jay West

Need pinouts for MDB Systems DLV11J serial line interface

I've got a serial line interface in this LSI 11/23 system I've got here. It's made by MDB Systems and is model DLV11J. I've got the manual for the DLV11 but it gives the digram for one big 40 pin Berg style connector, whereas the DLV11J has 4 10-pin Berg style connectors. Does anyone have the documentation for this? And now for a really stupid question: Can the 11/23 run RT-11?
