Metric hardware on cars - even North American built - has been very nearly universal in North America for the past 15 years. There are a couple exceptions still, like lugnuts. (Though by no coincidence the most common lug nut hex sizes on small cars are 3/4" and 19mm, and it's nearly impossible to tell whether it's metric or not by the hex size!) Strangely enough, spark plug threads in North America have been metric since the beginning of time, but the heads are still fractional-inch. Tim.

looking for an IBM 8525

by jlobocki＠gmail.com

hello, I'm trying to find a reasonable IBM 8525 all-in-one system. I've seen the ones on ebay ($200! before shipping, for a computer from the late 1980s that were in high abundance) if anybody knows where I could get one reasonably (preferrably close to illinois) please let me know, thanks! picture: http://www.recycledgoods.com/images/s_p_20127_1.jpg

Free DEC Digital Equipment box (Computer)

by rborsuk＠colourfull.com

Here's a DEC computer I'm tossing out. Don't know anything about it. Can't find any model numbers on it. You can have it free, just pay for shipping plus a buck or two for packing stuff. It's small so I would expect it to cost too much. What you see is what you get. Computer only. USA only please. Rob ps. Some pics http://homepage.mac.com/irisworld/ebay/dec_box1.jpg http://homepage.mac.com/irisworld/ebay/dec_box2.jpg pss. Nope. Didn't bother putting it on ebay. Not worth my time to test and such.

3.5" floppy jumpers

by rescue＠hawkmountain.net

I have 3 3.5" floppy drives with configuration jumpers (and 5 times as many without :-) ). Ons is a Chinon FZ-357, and has jumpers for: MD, RDY, MM, DC, and TTL/C-MOS. Another is a TEAC FD-235HF and has jumpers for: H HO, OP, LHI, HHI, and a position (but no header pins) for FG. The last is a Sony MPF520-1 which has 2 rows of 3 pins... and I have no idea what they are for. I understand some abbreviations... RDY (ready), DC (disk change), but not MD, MM, TTL/C-MOS (assuming this is for interface logic levels?), and the TEAC ones I don't know at all. The Sony one is a mystery, and a google search hasn't turned anything up... don't know if the headers are for selecting D0-D3 only... or more than that. Can someone fill me in/point me to web pages on these 'magic' jumpers for these drives ? Thanks, -- Curt

semi-monthly ebay grumble

by dgriffi＠cs.csubak.edu

One again, I'm getting the grumbles over Ebay's policies: its impenetrable policies on how much much I pay for what, lack of protection against insane buyers, a constantly changing look and feel, and so on. I tried out chasethechuckwagon.com for selling a couple video game carts and I like it. Their whole fee structure is generous and easily explained in one paragraph. The only problem is that I don't sell that much in the way of video games. I don't know what a good alternative for classic computer stuff would be. Right now I'm looking closely at ebid. I think this week I'll run a few things there and see what happens. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

Unused RK06 heads

by quapla＠xs4all.nl

During cleanup I found 3 unused RK06 heads, Dec partno 74-14130-12. They are still in their original box. Next to that I have a few more RK06 heads, new, but not in a box, as well as 3 or 4 RK06 servo track heads (these have an extra cable + connector). Maybe this is Dec partno 74-14130-13 ? Make me an offer. Ed

Flat screen for monochrome Sun output?

by silvercreekvalley＠yahoo.com

I've been trying (unsucessfully) to get various flat screen monitors to display the output from a sun monochrome frame buffer. This is proving tricky. The monochrome fb outputs 1152x900 if I recall correctly and its proving difficult to get any monitor to sync to this. Note the output is analogue not the older ECL (?) type display. Old CRT multi-sync monitors that sync on green handle this OK. Can anyone recommend a modern flat screen that will work with this kind of framebuffer? I do have various video processing units that can scale and process the output, but I'd rather not use these as they are already in use for other tasks. Ian.

Well, my use is just for general programming printouts on a PDP 11/23+. Is the LA75 a viable replacement for the Letterprinter 100? The 75 isn't period to the 11/23, but my concern about the 100 is ribbons. Ribbons for the LA75 are plentiful and cheap. Thanks Jim, Tony, Allison for your replies. JS

What's a LK207-EE ?

by bob＠jfcl.com

I give up - what's a LK207-EE? http://www.sparetimegizmos.com/Downloads/LK207-EE.JPG It's clearly a cousin to the LK201; it has the same keys as a LK201 but with a different physical arrangement. The paper labels stuck on the keycaps would make me think that it was used in some kind of stock broker application, but I've never seen or heard of anything like it before. Bob

ICL 1900 hardware documentation available

by aek＠bitsavers.org

I just put up a large collection of documentation on the 1900 hardware over the past couple of days under http://bitsavers.org/pdf/ict_icl/1900 Has anyone heard anything from Brian Spoor lateley? I'm concerned since his last post on AFC seems to be from about a year ago.

MITS Disk Boot Loader manual

by rcini＠optonline.net

All: I?m working on adding support in the Altair32 Emulator for directly reading WAV file samples of audio cassettes. Initially, I?m working with the 88-ACR but it should be a snap to modify that code to support the KCS. A WAV sample sent to me by the person who asked me to look into adding this capability is a cassette from 1977 called the MITS Disk Boot Loader. I?ve known this to be usually distributed on PROM, but I guess if you didn?t have a PROM board, the cassette makes sense. I actually have the source and ROM binary already because I use it for the floppy disk support in the Altair32. Anyway, me and a buddy of mine are starting to parse the WAV samples and it would help greatly if we could get a copy of the manual for the DBL. The owner of the tape doesn?t have it. What I?m really looking for is the toggle loader or whatever was used to bring the DBL in from cassette. If anyone has it and would be willing to scan it for me, I?d appreciate it. Thanks!

Mystery paper tape reader

by toby＠coreware.co.uk

Hi, I was digging through my collection at the weekend and came across this paper tape reader(?). Can anyone help me identfy it? I've put some pictures up on my blog here: http://www.pdp8.co.uk/2008/11/26/mystery-paper-tape-reader/ It is labelled on the front as a ?Paper Tape Comparator?. It has an optical array for scanning the tape and an adjustable width feeder to support 3 different sizes. I can't find any indication of its make which makes me wonder if its scratch built with bits from another device. On the back is a female 25 pin D socket which I assume to be an RS232 outlet. There is also a 3 pin power socket in a format I don?t recognise. Any information would be greatly appreciated.

After an H960 rack..

by toby＠coreware.co.uk

Hi, I don't suppose anyone in the UK has any H960 DEC racks looking for a good home? I'm in the process of moving all of my collection from my storage unit to my office server room and I'm short of racks to put it all in. Would be nice to put it all in correct period racks. Condition not important as I am a dab hand at cleaning and de-rusting. Thanks, Toby -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

New home sought for a PDP-11

by gordonjcp＠gjcp.net

Hi all, I've come to the conclusion that it's time my PDP11/73 went to a new home. Not a terribly easy decision to make, but I just don't have space to even get to it to switch it on just now and I'd rather see someone else get some use out of it. Anyway, here's the spec: PDP11/73 in a large Baydel cabinet with a 40M-ish MFM drive RX02 floppies 2 x RL02 plus a spare RL02 2 x CIT101 terminals VT520 terminal VT220 terminal LA36, spare ribbons and paper spare boards including 11/03 bits, a couple of opto-isolated I/O boards and some ADC boards DEQNA about a dozen RL02 packs large box of RX02 disks RT-11 V5.2 manuals Pick up in Glasgow. You'll need a van, although not a very big one, to shift it. A large estate car would be too small unless you broke the rack down into panels - a PITA, I've done it before though. Mail me on- or off-list if you're interested. Gordon

Hmmm . . . that technique might work for my 2N2/256 BSCP project! It also occurs to me that the machining could be done with the drive mechanics, provided it's rigid enough and you take very light cuts. You would fabricate a cutter head that bolts in the same way as a R/W head. To take a cut, you just tweak the adjustment screw(s) and turn an additional "feed" screw to cut the track the right width. Heck, you wouldn't even need the feed screw. Make the head so it can slide laterally a millimetre or two, then you could move the cutter head back and forth by hand, the same way the Fonly lathe works. It also might be possible to just lap the R/W heads in with a tiny amount of jewer's rouge, then carefully clean all the grit out and readjust the heads to give the right gap. -Bobby

Seeking Proteon P4100+ router manuals

by dave＠mitton.com

Sellam, et. al. As others have contributed, Proteon was an independent network vendor in the 1980s. I'm a little unclear what became their corporate fate, (I forgot about DEC buying source code) but they did eventually come apart due to market forces. They were an early token ring manufacturer, with their own product. When IBM pushed their technology into the IEEE 802.4 standard, they adapted with the market. They also made multi-protocol routers, and since they weren't Cisco, Digital did do some work with them. I had a 4100+ and a 4200 in my development lab. Unfortunately for you I don't think I took any of that stuff home. I was the technical lead/architect for a DECnet Token Ring Data Link specification. As part of that program, I also specified how to interface DECnet-DOS/Pathworks on to PC token ring devices. We worked with Proteon to put DECnet routing support into their routers, and I think they are whom we got to OEM an 802.4 Qbus NIC card for us. (with DECnet VMS support!) This was all to deal with the pressure IBM was putting on the PC and networking business at the time. (my memory is fuzzy on that now.) God I'd love to see what happened to the customers that swore that token ring was so superior to Ethernet that it was going to rule their networks going forward. IBM put some interesting crocks into their LAN chips wrt multicast addressing that really messed things up. I'm glad to see that chapter of history closed. I may be able to make some personal contacts to see if they have anything around. I woundn't be suprised if there is a Proteon old users/collectors group out there somewhere.

The curious approach to "18pin" printing was twofold. One was to allow fast draft quality printing and the other was rugged high quality printing that could still punch multipart forms with a known reliable head. At that time there were a few 18 pin heads but they didn't have the long term life at sustained high print rates. Note, this is a 1984-5 design so understand that many printers at that time were of smaller or less rugged style or really imposing printers. The LA100RO is most valuable to businesses that still used wide pinfed (assuming you have the forms tractor) multipart forms. In the high quality mode it does print decently and the graphics printing is not as slow as some dot matrix were. Allison

More stuff uncovered. I have several (~5, actually) Interlan NT10 transceivers to dispose of. These clamp on to coaxial backbone ethernet cables and pierce the jacket (vampire tap) to make a connection. They have an AUI port to connect your equipment to. If you are interested in them, make me an offer for my time to box them up and take them to a shipper. If there is no interest, they will get recycled.

I can't help you with manuals, but I will confirm that Proteon was indeed an independent firm in the 80's. During the early and mid-80's I was a member of Novell's technical staff during and had a good working relationships with several Proteon engineers. Novell, of course, had PC networking software and was working with just about any and all PC networking hardware vendors to make sure that there was a NetWare driver for their gear. At that time, Proteon had their own flavor of token-ring over twisted pair style hardware call Pro-Net. I don't remember the details or the transfer rates, but it was not particularly successful and later Proteon ended up joining the shift of the industry to Ethernet. Somewhere along the way, in the very early 90's, I think, they combined with 3Com. If I remember right, Proteon was located in Waltham, MA during the 80's. - Jared

FS or FT: HP75D and 82164A (HP-IL/RS-232C Interface)

by joachim.thiemann＠gmail.com

Hello, in an ongoing effort to thin out my collection, I've decided to sell or exchange some old HP bits that I'm sure are more useful to other members of this list. They should probably go to the same person, though the latter might be useful to some HP41 owner, too :-) HP-75D, with power supply, 8k ram pack, about 16 magnetic strips and one abrasive cleaning strip, and I/O Rom. I only have the manual for the I/O ROM, and the June 1983 issue of the HP Journal; that is the only "manual" I have for the 75D. I don't have the battery pack, I did at some point, but can't find it anymore. Some cells were dead, anyways - I think I kept the plastic parts, but it may be lost. It's fully functional (on AC power), but looks used (of course). Two of the feet pads are missing. I also have the 82164A HP-IL/RS-232C Interface, with power supply and manual, but I never had any HP-IL cables, so I could never test it :-( This one looks as if it came just out of the shipping box. I'd be happy to trade for a more modern HP calc (HP48SX or better) or interesting MIDI gear - otherwise I'm open to offers. Pic at http://www.ece.mcgill.ca/~jthiem/IMG_1916.jpg Oh, I also have an HP Omnibook 600C (working except the left mouse button) that I'm trying to let go. I'm in Montreal, Canada.

keypunch equip on govliquidation

by brian＠quarterbyte.com

Looks like the lot has 4 brand new 029s and two used machines, at least one of which is an 026. Somebody go get these! Or, do what I did in 2001 when a lot came up, and get a group together to buy them and divvy them up. These don't come along that often. Looks like there is some interesting old radar display gear in there too, which some military buffs would probably want. Are those scope hoods made of Bakelite? http://cgi.govliquidation.com/auction/view?id=2037010&categoryId=c7149 There's a whole bunch of other stuff in the lot, but you can call the DRMO staff and see if they can either keep and relist the remainder, or give it to a surplus dealer. There are usually surplus dealers hanging around happy to haul off whatever doesn't sell or what gets abandoned. It's the logistics of shipping and dispersing the stuff that's painful. Looks like the four new 029s are crated, the 026(s) are sitting on pallets, and they'll have to be padded and strapped. In the 2001, I used freightquote.com and scheduled a pickup & had the units sent to the people in the group. FYI I just looked at the bills of lading, we listed the factory-crated 029's as 520 lbs each, and the 029s on pallets as 310 lbs each. At today's rates, you should be able to ship a palletized unit from Ohio to, say, California, with a liftgate delivery, for about $250, and a crated unit for about $350. I'd be interested to know on or off list what happens with these, punched card stuff is one of my areas of interest. Brian

Interdata Model 74

by toby＠coreware.co.uk

Hi, A couple of years ago I bought an Interdata Model 74 CPU and I'm pondering what to do with it. I'm leaning towards rebuilding it to working condition next year and I was wondering if there are any other Interdata owners out there? The machine is in generally good condition, although I have has no power supply with it so will need to find or build something suitable. Unfortunately I have no documentation and so if anyone has any engineering documentation for these machines it would be a great help. Bitsavers has some details on the Model 70. Does anyone know how similar the Model 74 is to the 70? Thanks, Toby -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

I'm not likely to ever find another .029 in as new condition, presumably with the program drum which I've been outbid at silly money on eBay. Ohio to California is quite a long way, so maybe 2 or three times as much for shipping across the Atlantic, would be worthwhile for an AS NEW one, but not for spares. As long as it can work on 50Hz mains frequency, voltage no problem. I would also be very interested in an old control drum if there's one in the .026 and it gets scrapped. The printing mechanism too maybe if its not too difficult to remove. My alternatives are to restore my IBM 836 keypunch (like an 026 but with more bells and whistles) or to resurrect a spare online punch and interface it to my Mac. This will take many hours of effort, though it would also get me a fairly slow card reader. The mechanism is an IBM design made under licence by British Tabulating Machine Co (BTM) and its successor company, International Computers and Tabulators (ICT), the main mechanism of which seems identical to the one on the IBM 1401 restoration web site. Old keypunches just don't seem to come up any more in the UK.

PDP-8/E H724 power supply and serial interface

by pete＠dunnington.plus.com

I've taken my newly-acquired PDP-8/E apart to clean out the dust and disintegrated foam, but I've not powered it up yet. (In fact it's still in pieces while I sort out the foam). I'll be checking the capacitors before I go much further. Part of the reason for not powering it up is that it's a 110V version, and here in the UK my mains is 240V. Looking at the engineering drawings (on David Gesswein's site, and Highgate) for the H724 (110V) and H724A (240V) supplies, I see transformer taps shown for both voltages, and on the face of it, it should be very easy to convert. Just a matter of moving the connections from tags 6 and 9 of the relay (or "realy" as the schematic calls it :-)) Has anyone ever done this? Another question: There are four 1N4721 rectifier diodes used for the +8V and +15V supplies (two pairs for two full-wave rectified supplies). Someone before me has disconnected one end of one of them. Usually that's because it's gone short, but my meter says this one is OK. Any ideas why? I'm also lacking any serial interface for this machine. I do have some other spare boards; is anyone (especially in the UK) interested in a trade? -- Pete Peter Turnbull Network Manager University of York

Are they really saying the keypunches only cost them 100 dollars each new (400 for 4 and 200 for 2)?

Nicolet manuals and software

by chrish＠precisionmetrology.com

Mr. Joe R., I am a manager for a calibration company and ran across your web page stating that you have several old Nicolet manuals. When I clicked on your link for them it told me that this was an invalid link. I am curious if you have a manual for a Nicolet Integra 20 Oscilloscope. I am looking for calibration information and having a hard time finding it online due to the age of this equipment. Can you help me out? My Regards, Chris Henley Lab Manager Precision Metrology, Inc.

computer graphics in the 1950s

by legalize＠xmission.com

What was the first machine to have some sort of graphical display (most likely oscilloscope style) driven by a computer? SAGE is the first one I can think of; I don't recall the predecessors at MIT having any sort of graphical display. Then, after the first machine, besides SAGE, what systems were utilizing graphic displays in the 1950s? Did the IBM commercial derivative of SAGE use any graphic displays? -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

anybody have any IBM 8525's?

by jlobocki＠gmail.com

hello, Im trying to find one of those all-in-one PS/2 computers that IBM had in the late 80s, some were under the "EDUQUEST" badging, but most were the all-in-one 8525, and for some reason those who are selling on ebay think they have one of the rarest machines in the world and charge as so, and it really makes me regret not grabbing one from the salvage pile when they dumped all the ones in 99 when i was in middle school. anyway, does anyone have one they are willing to part with, or know of a cheap source of them? thanks -Joe

RS232 voltage level converter box

by mbbrutman-cctalk＠brutman.com

I came across something strange that I need some help with. Pictures are here: http://www.brutman.com/2008_1117_140718_RS232_conv_back.jpg http://www.brutman.com/2008_1117_140718_RS232_conv_top.jpg It looks like a converter box that takes TTL level serial signals and converts to RS232 levels, kind of like the MAXIM single chip solution except that it is using 1488 and 1489 chips. The problem is that it came with a PCjr, but it doesn't physically plug into a PCjr. The onboard serial port is only 16 pins, while the rectangular connector here is 20 pins. It physically doesn't work. Does anybody know another machine or card that might have used the 20 pin header for a serial port? I'm almost thinking that I'm missing another piece (a card internal to the machine) that the header goes to. Regards, Mike

I'm no expert, but I've done a little ULTRIX sleuthing myself over the last couple of years, learning more about ULTRIX and how to use it on my c. 1990 DECSystem 5400, which is RISC-based. From my experience, primarily with with ULTRIX 4.5, 4.3, and 4.2, I'd say that the 4.2 discs, one each for VAX and RISC, would be considered a 'complete set' for each architecture. The online documentation disc is probably a companion for either or both of these 4.2 install discs. I'm not acquainted with the earlier releases (though I'd like to be), but it would appear that the ULTRIX-32 V3.1 with UWS V2.2 should be considered complete (for both VAX and RISC) since you have both the ULTRIX OS + UWS on the one disc, which also looks to supersede the ULTRIX-32 V3.1-UWS V2.1 UPDATE disc. As for the V2.0, I have no idea if you have a complete ULTRIX + UWS package, or if it is just the UWS. - Jared

Hi Dave, but IIRC, I just put you in contact with Robert, who gave you one of his. Though he got some of his from me, so it may have been indirectly one of my machines... If it were mine, and I'd given it to you, I'd have no objection to your selling it for as much as you can possibly get for it. My theory is, the more value it acquires (by somebody paying for it) the less likely it will be to get scrapped, hence the more likely it'll be to be preserved. On the other hand, I *know* you are a knowledgeable collector and know which end of the soldering iron gets hot without having to grab it, so I'm happy it's in your hands. One reason for me to take this philosophy is that I don't have time to do myself the things I'd really like to do with my collection - like imaging floppies! I have 'em, but not imaged. They are in climate-controlled storage - that's the best I can say for myself. I'll hunt for mice. I don't think I kept a spare, but if I did, I'll let you know. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

differences SA1000, ST506

by lehmann＠ans-netz.de

Hi, I wonder if a ST506 drive can be used without problems on a SA1000 interface controller. The signals seems to be the same, but ST506 is working on a slightly higher transfer rate.

What is this system?

by roger.holmes＠microspot.co.uk

Now I have more space in my computer room my elder brother offered me two systems he picked up some years ago. I don't know much about either, but bitsavers has references to one, which is a Texas Instruments 990 with twin 8 inch floppies and a terminal. I have not tried powering it up yet and I dont have any boot disks but it looks interesting. It has a 12 or 13 slot chassis with most of the standard cards present except no printer card. Is this rare, can I get boot disks, would anyone want to buy it, what can I do with it? Much the same questions for the second system but also, what is it. It too has two 8 inch floppy drives, two volumes of manuals for Xenix but no floppies. It is marked "Advanced Micro Computers Inc Microprocessor Development System 29/05". There is a sticker saying Memec Systems Ltd. The front panel is divided into two, one says "Support processor" and the other "Microprogrammed system". Could this really be a proper microprogrammable system or is it just system using a microprocessor. Either way, which programming/microprogramming architecture is it? Any relation to the AMD 2900 bit slice chips? For a couple of months I wrote microcode back in about 1974 but not on this system.

NorPak???

by Reid.Allen＠eni.com

Norpak was a logic device that used only 'NOR' gates. It preceded the PLC concept. The gates were hardwired. Since any logic function can be created using negative Boolean operators (NOR or NAND) they were usable for solid state control systems in place of relays. We used a Norpak system at the San Francisco International Airport on a plane fueling system in the middle 1960s. They had 10 NOR gates per module, and we wired modules using something like #20 AWG wires with some kind of termination on the end that could be inserted into the Norpak units. One had to be very careful using the units because after the various functions and their arrangement had been designed there were often redundant gates in series that could be eliminated, but this caused transparency of design to be lost. I was working for the Standard Oil Company of California in those days down on 225 Bush Street. Reid C. Allen, P.E.

by rescue＠hawkmountain.net

I have graphics boardset for my R4K Indigo 2 (non impact) (FHV1/VB2/RU1/GU1) which includes the Galileo video board (FHV1). I can get a breakout box... but I can't locate a cable ? Does anyone here have a cable, or a cable + breakout box ? If so, what do you want for it ? -- Curt

COBOL Poster

by silent700＠gmail.com

I've finally gotten around to photographing a poster I've had for a number of years. Hoping it triggers some memories for at least one person here. I'd love to know who made it, when and most of all *why*: http://flickr.com/photos/chiclassiccomp/3037313448/in/photostream/ It's fairly large, maybe 3'x5'. It's actually textured - all the white areas are printed with some sort of coarse sand or grit. Right above the lower brown bar is written in pencil "A New Language" and signed, as far as I can tell "D. Meeny." Googling this info has turned up nothing for me. This was some serious work. I'm not one to question an artist's muse - but someone, somewhere, at some time, sure loved them some COBOL.

Offer: VGA Video card "collection"

by wpileggi＠juno.com

It's the end of my fall clean-up, and I've decided to discontinue "collecting" VGA video cards any more; though the proper term might be "accumulate"... I did find it fascinating to note these were state-of-the-art in their (brief) day, we spent upwards of $300-400 on some of these and they are now boards I pull to scrap... Roughly 1990-1999, ISA, PCI and AGP. Been doing this for the last 10 years or so. I have a list of brands and models, please email me off-list request a copy. Anybody else 'collecting' VGA cards? I don't have a price, is there a market? I also have a list of Creative Labs Sound Blaster cards...Bill KA3AIS ____________________________________________________________ Planning for retirement?

Photos of the N8VEM ECB Bus Monitor

by lynchaj＠yahoo.com

Hi All, Attached is a link to some photos of the N8VEM ECB bus monitor I just built. http://groups.google.com/group/n8vem/msg/2fe8df76d05be1d5?hl=en The design is pretty general as a Z80 bus monitor and the original C'T Projekt article mentions you can build an adapter to convert the ECB interface directly into a Z80 40 pin DIP socket. Although I haven't made the adapter socket myself, it makes perfect sense to me since the ECB bus is essentially just buffered Z80 bus signals and the bus monitor should not notice the difference. If you have any questions, just let me know. I have several of the PCBs left if you'd like to build your own ECB bus monitor. The parts are fairly inexpensive items and the PCB is only $20 plus shipping. Clive and Rolf posted a bunch of videos of the ECB bus monitor in action so you can see those to if you'd like. They are on the N8VEM website and on Rolf's ECB pages. Thanks and have a nice day! Andrew Lynch

I believe I skipped over that in responding to a thread about LCD monitors and output from late 80's and early 90's workstation framebuffers, but the 380 displays just fine on a 20" Dell LCD monitor using a HD15 to 3-BNC cable off of eBay.

Who wants to help read a Saturn V core stack?

Putting to bed the idea of the "core rope" program store, the 1964 document on the launch computer is pretty clear that this is ordinary read-write core storing the program: http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19730063841_19730 63841.pdf In particular, item 2-37 begins "Reading a ferrite-core memory destroys the information in the memory." It then goes on to describe the restore part of a read operation. No mention of "core rope" is made. The document, all 200-some pages contains a great deal of detail on the computer, including memory operation and organization. Cheers, Chuck

What processor cards are installed? Can you > tell me anything about the VSIMM capacity? I haven't touched the box in a long time. What I remember is that it had two processors, and they were the fastest available for that model. It had the largest VSIMM available (8Mb?). It had 2 disks. As I recall, it had the maximum possible memory compliment. Everything I remember about the box says that as SS20's go, it couldn't get any better. > > I'd mostly be interested in trades. > > What sort of stuff are you looking to acquire? My interests are wide and varied: Old computers (pretty well set with Sun and DEC), radio (ham radio and tube receivers like All American 5's), photography (film/digital) and interesting old tidbits of technology. The one thing I have yet to find is anything from Data General. I have family that wrote AOS/VS for DG and finding and example would be really nice. One need I have is for a microscope capable of 200x or 400x for working with my barnyard animals (I'll spare you the details of what I need to look for at the microscopic level).

Shouldn't that be one digital scope channel for every bit in the word? > The rise times of the address and inhibit lines Do we know this core memory has "inhibit lines"? My only core experience is with 2D planes and I've not heard of inhibit lines, maybe they are the magic that allowed 3D stacks to be made. On my core, half the current required is supplied on two separate wires, if you don't know the current required and you send the critical amount down one wire you will clear the entire memory in one go. > > are mostly to be slow enough that it doesn't cause the sense > amplifier to trip on the coupling in the selected address line. > Other addresses are protected by the matching signal on the inhibit > line.

seeking SS20

by john_finigan＠yahoo.com

Yes, I have one with a pair of SM52Xs somewhere, for quad SuperSparc at 50 MHz with 1 MB cache each. A couple of years ago I put NetBSD 2.0 on it. Compiling Apache, it was just a little bit faster than dual SM71. Of course, SMP was brand new in NetBSD 2.0 The bummer is that with the 50 MHz CPUs, you have to run 40 MHz bus, since the bus must always be lower frequency than the CPU. What I always wondered is, if Sun could run the SM41 at 40.3 MHz and use the 40 MHz bus, why did the SM51 not run at 50.5 and allow 50 MHz bus? I assume the obvious reason was "they tried and it didn't work."

Saving 1962(year) mainframe data

by roger.holmes＠microspot.co.uk

Thanks for your thoughts, yes I think that could work, though a bit slow for 90,000 cards. As some of the cards are printed, might need to scan them twice, once with a black background and once with white. I might use that method for the 160 column cards. For the 80 column cards, I expect to soon have a working card reader. Now I can get to the logic properly it should not take long to find out why the 'zone' is being decoded incorrectly. The 'numeric' is working fine already so I can read cards with columns of just '0' to '9' on them. One day I should even be able to read pure binary cards through the check reading brushes of the online card punch, though for protection I might remove part of the punching mechanism to stop it making more holes by mistake. I have even been toying with the idea of re-building my spare punch mechanism, putting some TTL logic in it and connecting it directly to my Mac laptop through a serial to USB converter. Might be easier than getting my IBM keypunch working without any diagrams for the relay logic. However, the question I was asking was how to encode these special characters. I currently know of two alternatives. One is to put them in pure text files with a two character sequence for the special characters. ACONIT in France have used a character starting Hex F as a marker. The lower nibble holds four of the bits >from the top 4 rows and the second character holds the bottom eight row bits. This means even fully laced cards can be represented. The other is to put them in UTF8 form which has characters with rings around the numbers 10 to 15. I think they probably have the fraction characters, pound sign etc as well.
