This died out, Do we want to do our own Wiki? The last suggestion was that we make entries at WikiPedia [ http://en.wikipedia.org/ ] I think we would be better served with our own Wiki, we would be able to arrange the data in a way that would mean something to us. Otherwise would have to have our machines peppered about in between other subjects. I suggest this arrangement: Introduction Year : Manufacturer : Model : User : Individual machine Some Wiki's also allow for a user's home page. There I sugest each user tell us about their collection / machine (with a link to the machine page)

PDP-11/73 boots!

by ian_primus＠yahoo.com

A few minutes ago, I got my PDP-11/73 to boot. I installed the disk controller and connected the hard drive. I typed in the boot program, and booted from the BRU standalone tape. It worked! This time it didn't crash, since it could find the drive controller. It booted up and displayed this: http://24.194.65.231/images/screen1.jpg I haven't figured out how to get past this though. Typing /dev gives me this : http://24.194.65.231/images/screen2.jpg I tried typing in a device name, but it just gives me a syntax error. Hardware wise, I think that everything is working together properly. I don't know how to use the software though... To start off with, I'd like to run a flavor of UNIX on this, since I know UNIX very well. Any reccomendations as to what I should use? BSD 2.11 should work on this, but I don't know how well. In the future though, I'll probably install a PDP specific operating system, like RSX or RT11, and learn that, but at least as I get things going with the hardware, I think I should at least stick to software I know :). Also, once I do get something installed on the hard drive, how do I boot it? Currently, toggling the boot switch doesn't boot the machine. Should it? Will I have to type in a bootstrap code every time, or can I make a ROM do it for me? Here are some more pictures I took of my current setup. This is what the computer looks like at the moment. The side panels are off the rack, and the cables are just hanging around the front for the time being as I am just testing at this point. I'll neatly route them out the back later. I'm currently using a Lear Siegler ADM3A, since it was convenient when I was first hooking it up. Not only that, but I really like the ADM3. Mine's missing two keys, but it works. http://24.194.65.231/images/pdpworking.jpg This is one of the brackets I had to make to mount the Fujitsu Eagle into the rack. It's made out of a Home Depot bracket that originally was wider, and had two little wings coming off the top of it. I think it was intended to join two 2x4's together somehow. I cut it down with a Dremel tool, and drilled new holes in it. It worked out very well. http://24.194.65.231/images/homemadebracket.jpg Ian Primus ian_primus(a)yahoo.com

Source for disk & head cleaning?

by aek＠spies.com

> HP recommends cleaning the heads on the 14" drives with a flat wand, and a cleaning sleeve that fits over it. -- Tex-wipe made them They're called Tex-Sleeves and are a blue plastic split wands that look like oversided tongue depressors (1" x 6") with a lint free cloth sleeve that slides over that like a sock. The ones I have are in storage, will retreive the part numbers for you. I have extras of the plastic parts, but am running out of sleeves. This is exactly the right thing for cleaning 2315/5440 style upper/lower heads.

Free IBM System/36 (5362) and Kienzle 2000 in England

by vcf＠siconic.com

Here's another one. Why does this seem familiar? Didn't I already post this to the list? Or did someone else? At any rate, it just plunked into the hopper so I'm passing it along. An IBM 5362 in England. The address makes no sense to me: I think this is an estate sale company in four locations(?) North Leaze Farm, North Cadbury, Yeovil, Somerset. Take your pick. Sorry, my geography of the UK does not enable me to figure out where this is exactly. Or maybe it IS the address (quite odd by US standards at least). Or maybe it doesn't make sense anyway. Whatever. There's also a Kienzle 2000 "magnetic card accounting computer" which sounds rather cool. Please do contact Bill Longman directly.

Flat Earth?!

by tothwolf＠concentric.net

For those of you who may have wondered where I'd gone, I really didn't fall off the face of the Earth (and contrary to what some folks might believe, the Earth still isn't flat). I'm currently recovering from a multi-drive failure in my RAID-5 array. I was very, very lucky in that only one of the drives died a horrible death, with the 2nd having a semi-recoverable error. The second drive failed before the array could reconstruct itself, and my spare drive was already in use. Had I been running an OS where I didn't have the source, I probably would have lost all of my data (roughly 25-30GB currently), but since I had the source to the RAID software, I think I've managed to recover most everything. Let this be a warning to anyone else with a nice RAID setup who also doesn't keep current backups... My DAT drive died about 6 months ago, and Sony can't seem to cough up a service manual. [If anyone has any surplus DLTtape IIIXT tapes sitting around collecting dust, feel free to contact me off-list. I managed to collect a DLT2000 drive right before my DAT drive died that still hasn't attracted the proper tapes. I'd also like to find an inexpensive source for new or low mileage 4/9/18GB UW SCSI drives, as I think it may be best for me to replace the entire lot of old 9GB drives that made up my RAID-5 array.] I also have a number of things that still need to get sent out to folks. If anyone is expecting anything from me and doesn't hear from me soon, contact me off-list and remind me. -Toth

OK, mine concerns a PDP-11/40. When I got it, it wasn't in a rack, just lying on the floor, minus the power supply, a few wires cut, a bit of rust here and there, and no docs. At the time I didn't have a Unibus machine with a full lights-and-switches front panel, so I took it anyway. After 2 or 3 years of lying on *my* floor, I gave up trying to get a power supply sorted out, and gave it away to someone whom I suspect broke it up. The sad thing is that it had a full complement of boards in the CPU (my present 11/40 has no FPU, no MMU, etc) and a few extra goodies. Moreover, it turns out to have been been one used for the developmenmt of MUMPS, so it was actually a more historic machine than many. -- Pete Peter Turnbull Network Manager University of York

Source for disk & head cleaning?

by jwest＠classiccmp.org

I think I posted a query about this before, but don't recall any answers.... HP recommends cleaning the heads on the 14" drives with a flat wand, and a cleaning sleeve that fits over it. They also recommend the same device for cleaning the fixed platter, through an access port next to the heads. I seem to recall that old Microdata Reflex drives I used to work on wanted the same thing. You put the sleeve on the flat wand (the wand is much like a tongue depressor in shape, but a bit longer, and plastic), dampen with ISO 91, rest it on the platter through the access port, and slowly turn the hub by hand. I have searched the net, and can't seem to find a source for these wands and cleaning sleeves anywhere. I would have thought they'd still be around. Does anyone have a source for these? Thanks!

Some cool finds and info needed

by jrkeys＠concentric.net

Yesterday I go a Apple G3 (White) iBook with a cracked screen for $22.50 but it still looks cool. Today I was given a card from Future Domain Corp. called a Apple Signal SCSI Port, TMC-850MER? Anyone have some info on this? At a thrift I got a very heavy black case with a Motorola Reader/Programmer in the top half and a Digital Analyzer/Controller in the bottom half. Mounted on the top cover is a Motorola RTL-5820A PROM socket and there is a spare one store in the cover RTL-5821, There are also several cables in this storage area. I got no manuals with it and would like more information if someone has worked with one of these before?

Computer terminology and political correctness

by rdd＠rddavis.org

Did anyone hear that some bureaucrat, in charge of purchasing for the city of Los Angles, has sent a letter to all of the city's suppliers of equipment, asking them not to use the "insenstive" words "master" and "slave" in relation to equipment sold to the city? Maybe this means that there will be a glut of politically incorrect surplus computer equipment and documentation available there. Of course, they'd probably recycle it into scrap so as to not risk offending purchasers... too bad they don't just recycle the political correctness into something else. -- Copyright (C) 2003 R. D.

MDB MLSI-DB11 (DB11-H?)

by pat＠computer-refuge.org

I've just acquired a MLSI-DB11 (produced by MDB), which is a QBUS adaptor that sort-of looks like an SMD disk controller. I'm not quite sure if it's that, or something else. The closest thing I've found to what it is the DEC DB11-H adaptor, which I can't find any description of anywhere. The MDB card is a dual-height QBUS card with a 60-ish pin connector, 20 pin connector, and 2 smaller 10 pin headers on it (might be off by a couple pins on those counts). Does anyone know 1) what this is and 2) anything about it? Thanks, Pat -- Purdue University ITAP/RCS Information Technology at Purdue Research Computing and Storage http://www.itap.purdue.edu/rcs/

DC 30 tapes?

by rigdonj＠cfl.rr.com

I went scrounging a couple of days ago and found a big box of DC 30 tapes. Is anyone familar with these? Or know of any systems that use them? I THINK these came from a computerized component tester made by Seimens. They look like audio cassette tapes but are slightly larger. These tapes are made entirely of plastic and don't have the metal plate on one side like the DC 300 tapes, HP-85 tapes or DEC Compactapes. I think the Seimens component tester may be a rebadged tester make by Analog Devices. At the same place I found a big pile of Analog Devices plug-ins to mount and connect various types of ICs and other solid state devices but I didn't take the time to see if they fit the Siemens marked testers.

Unfortunately, it requires > RSTS/e 8.0 or later. I do not know if one of the RT or RSX versions > would fill the bill on earlier RSTS/e versions. That's probably 3.6x. Sadly, Frank da Cruz no longer keeps older versions of Kermit online (something I regret, as periodically I need to find yet another version for some newly-acquired machine, and also because I dislike the bloat that happened between C-Kermit 5 and 6). Luckily there are other places to find it. Thanks to Tim Shoppa, several DECUS tapes are available which have versions of Kermit-11. It's usually in account (directory) [356,040] on the tapes which included it. Look for the file k11ins.rno (or k11ins.doc, which is a flat ASCII file but most servers wrongly assign a MIME type of application/msword to it, just because of the suffix) for release notes. .rno is a RUNOFF file, the source for a document processing system akin to (but much older than) troff. 3.51 (Spring 1986) runs under 7.2 but doesn't handle binary files properly, and only builds under 8.0 or later. It's at http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/rsx /decus/rsx86a/356040/ 2.30 (June 1985) says: "This is release 2.30 of Kermit-11. It requires RSTS version 7.2 or later, RSX11M v4.0 or later, or RSX11M Plus version 2.0 or later, or RT11 version 4.0 or later, or P/OS version 2.0 or PRO/RT11 version 5.1 Minimum system requirements to run Kermit: RSTS v7.2 or later, with multiple private delimiters" It's at http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/rsx /decus/rsx85a/356040/ 2.17 (August 1984) says "This is release 2.17 of Kermit-11 for RSTS and RSX11M/M+. It requires RSTS version 7.2 or later, RSX11M v4.0 or later, or RSX11M Plus version 2.0 or later, or RT11 version 4.0 or later. Minimum system requirements to assemble and link Kermit RSTS v8.0 or later, with multiple private delimiters and RMS V2 Kermit-11 will run on RSX11M version 4.0 and RSTS/E version 7.2 as long as the task was built without using RMSRES. To be able to build KERMIT on RSTS version 7.2 or RSX version 4.0 you will have to get RMSLIB.OLB and MAC.TSK from RSX v4.1 or RSTS v8.0." It's at http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/rsx /decus/rsx84a/356040/ Most of these have pre-built binaries in the form of .hex files; these are flat-ASCII hex representations of the binary, intended to be stuffed over a serial line by a simple terminal emulator or whatever, in case you don't already have Kermit or something similar to transfer a binary. There are also de-hexifier programs in various forms (BASIC, FORTRAN, C, etc). Most of those directories also include other verisons of Kermit (ie, not for DEC OSs). I discovered that last URL I gave has C-Kermit 4C :-) -- Pete Peter Turnbull Network Manager University of York

Want to borrow TTY for a few minutes...

by v.slyngstad＠verizon.net

I mentioned this before, but the subject line may not have caught the right people's attention. I need access to an ASR TTY with the reader-run mod to do some final testing on some cards I am developing for myself and the group. If you have a pdp-8i or pdp-8L that's great, otherwise I can bring my 8L. I am in the Portland (PDX) metro area (Beaverton, actually). The cards have already been tested with a TTY which does not have the reader-run feature, so it is that specific feature I still need to test. Anyone out there who can help? Thanks! Vince

Paper tape

by davidmercier＠newengleng.com

Newer paper tape is not oil impregated at all but has a barrier / lubricant made from resins. Tape is still available from The Trybus Company in Pittsburgh. (412 367-1880) They also carry Mylar tape which I prefer. Quite often a customer will come to me with an old worn out executive tape and ask me to "do Something". I will generally read in the tape using a DSI reader that I have slowed down to 30 CPS and have narrowed the strobe width to 1/6 the charactor width. I will then use a FACIT 4070 to generate a new tape onto Green/Gold mylar. On executive tape using all 8 bits and no parity I use norton disk edit to make any manual repairs. This eliminates the need to splice fragile originals. David A. Mercier New England Engineering Services 25 West Street Stafford Springs, Ct. 06076 (860) 684-5980 Fax: 684-5982

PDP 11/73 is ALIVE!

by ian_primus＠yahoo.com

Last week I got the system unit and the tape drive mounted in the rack, and yesterday, I managed to mount the Fujitsu Eagle. Now I'm trying to figure out how to hook it all up... I have been tinkering with it this morning, and finally, about a half hour ago, I was able to see some activity. I found the information on the serial board in a handbook, set the terminal for the proper baud rate, etc, and connected it to channel 3 of the card. Powering it up gives me the @ prompt. So far, the only things in the machine are the CPU, the serial card, a 1mb memory board, and an Emulex tape controller. Now that I have gotten it to do something, I'm totally lost. I've never worked on a machine like this before. I don't even know how to type in the boot program. I have a tape boot program here, on a piece of paper, but I don't know how to type in the values. I've tried all sorts of commands, all of which yield a ?. Typing P seems to step the processor through something, as it prints 000002, and then typing P again increments that value. G prints 177777, and the LED on the tape controller lights briefly. Same thing if I toggle the boot switch. I tried loading a tape into the drive and putting it online, but I get no drive activity when I toggle the boot switch. So, can anyone offer hints or suggestions as to what I should do next? I'm lost... Thanks! Ian Primus ian_primus(a)yahoo.com

PAIA PVI-1, VT-103

by swtpc6800＠comcast.net

Here is a page scan and the text from a 1978 PAiA catalog. The PVI appears to be Don Lancaster's TVT-6. http://www.swtpc.com/mholley/PAiA/TVT6_640.jpg Michael Holley www.swtpc.com/mholley Don Lancaster's ingenious design provides software controllable options including: Scrolling Over 2K on-screen characters with only 3MHz bandwidth Full performance cursor Variety of line/character formats including 16/32, 16/64 even 32/64 User selectable line lengths You'll want to see the operational details on this first. The PVI-1K is not the universal answer to every video display requirement. In applications where its minor limitations present in?surmountable obstacles to a design, more expensive techniques should be used. If you are in doubt, the PVI is completely described in the July and August, 1977 issues of Popular Electronics. Reprints of these articles are the instruction set for this kit and are available separately for $2.00 postpaid refundable upon purchase of the PVI kit. Complete kit includes circuit board, all parts and instructions and is available in either of two forms. PVI-KM Ready to go with KIM's $34.95 wt. 1 lb.

Grandfather system RTE6/VM?

by aek＠spies.com

Thanks, Al, for the microcode rom dumps (however the 12823-80020.bin, F-SIS is missing - lost somehow during copying?). -- It should be there now I've seen that the base ROMs slightly differ from the microcode listing in the 2109-90004_1000EF_uPrgRef_Apr80.pdf from your site. What is the relation between both sets? -- The set that is up there was the last released set, and uses x8 proms instead of x4. Release histories of the firmware can be found starting on page 33-1 of the CE manual. I've hacked together a simple microcode disassembler for these ROMs, with the exception of the 1816-* ROMs that I do not know how to handle (any further info?). -- That is the MX IOP firmware. They are x4 parts (256x4, 82S129's to be exact) I suspect Bob Supnik or Mike Gemeny may already have disassemblies of that.

I want to say that the ADT was swapped in and out of core on a per-drive-basis as needed. But the core allocated was only big enough to hold 32MEG worth of available disk bits (per drive). So, 3*5=15, 15+32=47 I?m just going on memory on all of this, and that?s been 20 years ago now. Feel free to chime in here if my memory is not serving well enough. Mike Gemeny.

Reply to: PAIA PVI-1, VT-103

by nerdware＠ctgonline.org

I took a look at Paia's website, but it wasn't listed in the archives. You might want to go to www.paia.com and look for a phone number or email link. They like to hear from people with old Paia gear, and I'm sure there's someone there who will be able to tell you what it is. Paul ORIGINAL MESSAGE FOLLOWS: I acquired a PAIA PVI-1 circuit board yesterday, and a Google search brings up no information about this board. The main chip seems to be a GI 2513 with some 8 7400 and CMOS support chips. On the circuit board are two RCA jacks labeled TV and VID, two pots labeled "H POS V", a jumper for selecting 32 or 64, and another YES or NO jumper for the cursor. The code date on some of the chips are in the 1977 era. Does anyone know what this thing is, and does anyone have any docs? In the haul I picked up last week, one of the advertised VT-100s turned out to be a VT-103 and I am beginning to suspect ... with John's help :) ... that the dual 8" RX02 drives go to this unit.

RT-11 on a PDP-11/20

by ggs＠shiresoft.com

Can someone point me at the requirements for running a version of RT-11 (like v4 or v5.3, v5.4) on a PDP-11/20. I'm pretty sure I can get enough memory (in a BA11-K expansion chassis) but I want to know if there are other "gotchas" (like having an EAE). Also does anyone know where there is a reasonable copy of DOS/BATCH? I tried an RK05 image that's around on the 'net on one of the simulators and had little success. Did any version support RX01's? Thanks. -- TTFN - Guy

DECmate-III questions

by pat＠computer-refuge.org

I just recieved a few DECmate III "motherboards" which are supposedly functional (the guy is selling more of them on eBay right now, for their Intersil 6120 chips). Before I attempt to desolder the chip, does anyone have information on these things? I'm looking for information on what each of the connectors is, and the pinout of the power connector (J2) and kb/video connector (J5?). Also, any manuals or images of software disks for this thing would be nice : ). Here's what the connectors are labelled on my board: J1 and J? (can't see a label for that one) are 34pin headers, and I'm guessing go to RX50s, J3 is probably the 'expansion connector', J6 and J4 are serial(?) and J5 is the video/kb (?). I'm fairly certain that J2 is power, but don't know what its pinout is without playing with my DMM... but I'd rather get it right the first time and *not* smoke the board... Btw, J? hangs off of the side of the board, and is a right-angle header, unlike all the rest of the connectors. +------------------------------------------+ | ______J6______ ____J5____ ___J4__ | | \___DB25P____/ /___DA15P__\ \_DE9P/ | | _____________ +-+ | | |__34pin hdr__| |'| | | J1 |:| | | |:|J| | |:|2| | |:| | | +------------+ +-+ | | | | +--+ | | E30 | | | | | DC382 | | |J? | | | | | | +------------+ | | | +--+ | +------------+ __ | | | | | | | | | E25 | | | | | | DC381 | ___ | |J| | | | | 6 | | |3| | +------------+ | 1 | | | | | | 2 | | | | | | 0 | |_| | | |___| | | | +------------------------------------------+ -- Purdue University ITAP/RCS Information Technology at Purdue Research Computing and Storage http://www.itap.purdue.edu/rcs/

This was an MS-DOS device driver that remapped the standard HD 5.25" drive to be Rainbow RX50 compatible. Does anyone have this or something like this that works with current MS-DOS?

OT: hissing from a hub

by vcf＠siconic.com

I've got this 3Com OfficeConnect Dual Speed Hub 8 that is putting out this obnoxious hissing noise. It's loud enough to be annoying and add significantly to the white noise in my office. It sounds like the air is slowly being let out of a tire...forever. I've opened it up and found a capacitor with some brownish crusty stuff caked on the top of it. It also was bulged ever so slight at the top, as was another one right by it. Both are within proximity of the power connector. I didn't see any blackened spots on the enclosure indiciating that either had let out any magic smoke. So the question is, what is the most likely cause for this hissing? I've had a device before where the capacitor was causing the hiss (or at least I was pretty sure). There doesn't seem to be anything else in there that would cause the hissing (a bunch of ICs, a couple couls, a couple power transistors, etc.) Any help appreciated. -- 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 ]

Certainly not an oxymoron. I have a real soft spot for analog computers. The theorist in me wants to hear the term analog computer as a whole as describing a computing device in a different class from the sort we've been discussing. A part of me kind of wishes a different term had been adopted for these machines, but differential equation engine just doesn't have the same ring. Now if I had just had a way to rescue the EIA hybrid machine I used in college. Of course, I'd have no place to put it, but we can ignore minor details like that... Brian L. Stuart
