<Well, I guess there may have been some applications, but I doubt <if this has ever used the full potential of the 86/89 combination. <The design did realy borrow a lot of good mainframe ideas. Just to <early ? DEC LN01 used an 8086 and 8089 for the RIP (raster image processor). The 8089 did the parallel IO to the host (Dataproducts interface) and the band buffer to video serializer (7+ Mbits/sec). The band buffer depending on mode was either a 16bit wide scanline segement of binary data or the 8089 would use the band as raw data and translate it for font lay down. Both chips were working hard at 12ppm. Allison

how many heads, Cylinders on a Quantum 540?

<No offense, Allison, but the 1007 and 1005 controllers won't work with tha <drive at all, as both 1005 and 1007 are ESDI controllers.

Also my 1006 was used with them in the current system before I went IDE. Note we may be talking across part numbers as I have three 1005s that are each decidedly different from each other yet, the primary part of the part number is WD1005! I also have 4 flavors of 1002, three differnt lengths, one surface mount! Of all the PC controllers from WDC I have about ten, starting with the 1002 also the 1003, 1005, 1006 and 1007. The only EDSI controller I have is a non WD design and I don't ahve drives for that. <ESDI is a high-level interface not at all like the "ultra-dumb" <ST-506/ST-412 interface this drive claims to have, though it does use cable <of similar configuration, hence has similar connectors.

Computer History Lecture: January 13, 2000

by spicer＠computerhistory.org

The Computer Museum History Center is delighted to present: "Recollections of Early Paint Systems" Richard Shoup & Alvy Ray Smith January 13, 2000 18:00 hrs Building 3 (Moffett Training and Conference Center) NASA Ames Research Center Mountain View, CA 94035 In the early 1970s, with the advent of 1 Kbit integrated circuit memories, it became practical for the first time to build a semiconductor memory capable of holding an entire image and displaying it on a video monitor -- a picture memory or "frame buffer." This led to developments in interactive frame buffers, painting and drawing programs and other graphics-oriented software at Xerox PARC, the University of Utah, MIT, the NYIT, and elsewhere, and ultimately to the entire field of pixel-based graphics. Dick Shoup built the first video-compatible frame buffer and painting system, "SuperPaint," at Xerox PARC in 1973. His colleague and friend Alvy Ray Smith collaborated on SuperPaint, and then went on to develop the first full-color paint program and much more at New York Tech in the late 1970s. In this talk, Dick and Alvy will describe and demonstrate -- hardware gods willing --the original 1973 SuperPaint graphics system, and a Windows-based PC emulation of the NYIT full-color Paint3 program, exhibit historical footage of early graphics programs and achievements, and tell some stories of their early adventures in pixel graphics. Following the lecture, tours of The Computer Museum History Center's Exhibit Area will be conducted by Center staff. Refreshments will be served and admission is free. Attending: Please RSVP by January 12 to Wendy-Ann Francis. (francis(a)computerhistory.org) Due to government regulations, all lecture attendees must register to be admitted to NASA Ames Research Center.

Well ... that i8089 has to be a slave processor to something else. The notion of CP/M for something other than the "BIG-3" i.e. 8080/8085/Z-80, seems unnatural to me. I you can find an OS that actually uses that i8089, I'll be surprised, but really interested. I've got one on an Intel iSBC215 "Versatile Hard Disk Controller" intended for goodness knows what, which I mistakenly bought back in the early '80's, thinking it would do something "wonderful" and worthy of study since it was so expensive. -Not so! - The 11-bit bit banks in those memories are halves of 22-bit words which are SECDED compatible for 16-bit words of data.

how many heads, Cylinders on a Quantum 540?

Yup! That was a bad spec! I see where there are several Quantum drives with the 540 as part of their model number. This is the old Q540 form back in the '80's, though.

Olympia Olytext 20 OS question.

by ernestls＠home.com

I have an Olympia Olytext 20 computer but I don't have the OS for it. It's a single board, Z-80 system, with a 3.5 inch FD. The manual said it used CP/M-80 but I haven't been able to find any other information on the system, or the OS. No one that I've talked to knows anything about this PC, so I won't even hope that anyone here would have the OS but... I'm wondering if there is a way to make a new copy of the OS for this system? If I can find out the hardware addressing, etc., can CP/M 80 be made to run on it, and without a horrific amount of work? (I know, depends on what I consider a lot of work.)I don't mind tedious, if it's do-able. I've never done it before, and some of you may be chuckling about it but I'm just curious? Otherwise, this computer will just continue to sit, unused, on my bookshelf. Ernest

< Hi Tony, I have an 8089 in a CPM machine but I haven't been able to fin <out much about that chip. What can you tell me about it? 8089 is an IOP (IO processor). It is a super intelligent dual DMA channel and 20 bit cpu combined. I have a few and docs. It can run 8 or 16 bit busses in local or remote modes (or mixed). Commonly used with 8086 to offload the cpu from taking IO interrupts and doing high speed interfaces. While it could be used as a general purpose processor the instruction set and stucture was more for moving data (or tables of data) than arithmetic. < FWIW the same machine has ECC memory controller in it too but I don't <remember it's number.

Question for you 'big iron' collectors

by allisonp＠world.std.com

Actually this is not hardware specific but echos the points many have made. Stable mature systems we know how to use. Really CPM may have bugs but, they are known, true for many small and larger machines that are aging. This beats a lot of new hardware and software where buggyness is a grand unknown while work MUST be done. Allison

DEC boards avail

by oliv555＠arrl.net

Got hold of some DEC boards here in SoCal that were about to be scrapped. Some were going to another list member, but haven't been able to get hold of him (Dave, let me know if you still need the 11/24 bd). These are rather obscure devices, 2 M3110's(hex), 2 M3111's(hex), 15 M3102's(dual), 1 M8743(hex 11/24 memory) and 1 EMC2 memory (hex-depopulated). Separately, I picked up a rather dusty quad M8350 ("positive IO bus interface" ??). Anyone interested in any of these should contact me off list before the weekend. Yours for the postage, probably not more than $5 to $6 for a couple of bds. Dont really want to haul these back home to Houston, so if no takers will return to scrapper. Happy New Year to all! Nick

Question for you 'big iron' collectors

by nerdware＠laidbak.com

I've been following the list for about a year and a half now and I'm curious -- you guys (both genders) that have the room and the know-how to run the big stuff -- what do you do with them? I guess I'm not that familiar with non-business apps for minis and I'm just curious what someone using a PDP at home would do with it? Do you just write code for the sheer challenge of writing code? Have you written real-world apps? Is it just nostalgia? Or do you keep them running purely for historical reasons and don't have any practical day-to-day use for them? It just fascinates me that there are so many of you who run these beasts and I'd just like to know why. Thanks.

You have to be a bit careful: Again, I take it these images are not "distribution sets". I a hoping to post all the distribution sets of the various PDP-8/11 OS soon (sysgen stuff).

To be honest, I cant get to it at the moment lol...I have a ton of stuff I just got in, the Apricot among it. As near as I can recall, it was basically rectangular shaped with 2 disk drives on the front, the front being one of the narrow ends of the rectangle. I am really going to tear into this stuff tomorrow or Friday! I still havent got all of it to the house :-) I believe I can make quite a few decent systems out of all this stuff! And hey, to everyone who answered me, thank you so much! All this info is coming in really handy! Mark

Ontario Hydro for one still runs many PDP-8s and still buys RK05 heads. In some cases it is cheaper to run the old stuff than to get new hardware approved for use. I had a really weird contract in '92-93 that required a cpu to monitor and run quite a few sensors in a very hostile environment (we are talking sodium cyanide and sulfuric acid in the same sealed room -- HCN byproducts - yuck) for an experiment. A PC would last a day or two with such gases so I concluded it would be cheaper to wheel in a PDP11/34 with a bunch of A/D and DR11-Cs in it. We did so and the 11/34s lasted about a week and a half before the chemicals ate away enough of a PCB trace to cause the CPU/RK05 to fail. Went through 3 of them in a couple of months and the experiment succeeded. These old minis can take a lot of abuse... and they are great for real-time data acquisition. For the most part now it is just collecting..... john PDP-8 and other rare mini computers http://www.pdp8.com

It's not all the same font (unless someone made one up specially). The letters "pdp" are a tweaked version of Futura (ither Medium or Book, I can't remember which). BTW, the "11" doesn't look the same as on any of my PDP11 docs; normally, they're Helvetica Bold, but in the logo at the top of http://www.pdp11.org/, they're done in what appears to be a slightly-modified Futura. The "/34" or equivalent that you see in particular model numbers is normally also Helvetica, but stretched. I could give you a (scalable) PostScript copy of the "pdp11/34" logo if that would help... -- Pete Peter Turnbull Dept. of Computer Science University of York

Commodore 3040 drive problem + A1000 keyboard.

by black＠gco.apana.org.au

Hoping someone can help, Recently I picked up a 3032 PET with a dual 3040 disk drive. When I first turned the drive on, the power led & both status lights on the drives flashed in a regular pattern - 8 times. I checked & re-seated all the chips, now the lights flas in a regular 5 times pattern. Obviously there is a problem, but I can't find diagnostics for this drive anywhere, anyone know what the problem might be & how to fix it ? Also, I need a replacement keyboard for an Amiga 1000, am willing to freight >from o/s for this (I'm in Australia). Thanks Lance

It's sounds like I might >(and others) have to write some software(or use yours) to pool all the code >coming in through the above devices to a large NT server. There's no magic - you just have to have an extreme dedication to storing the original information - in its entirety - in an archivable form. This means, usually, reducing every piece of input medium into a "stream of bytes" file that will be portable through operating systems (such as Unix) which don't have an innate concept of "records". For 9-track and 7-track tapes, I prefer "TPC images", as made by many of the TPC archiving programs available for DEC OS's. A TPC image of a tape allows you to exactly reproduce the tape again later >from the image, including boot blocks and any variable-size data records in the file. See http://pdp-10.trailing-edge.com/ to see how I applied this to the PDP-10 software archives, and for pointers on the web to the many TPC tools available. After you make a TPC file, it's important to preserve the record lengths in the file before you transfer the file to a machine that doesn't know about records. For this, my preferred method is ZIP "-V" on VMS, where the "-V" qualifier makes sure that the file attributes and record lengths are all stored in the Zip file. Then you can move the file to Unix's and PC's which don't know anything about record lengths, because the Zip file *is* a stream of bytes. For block-oriented disk (and block-oriented tapes, like DECtape I and II) devices, the preferred archival method is a block-by-block image of everything on the original. This is easily done by, for example, COPY/DEV/FILE DEV: FILE.NAM under RT-11, or by doing a MOUNT/FOR of the disk device under VMS and then COPY DEV: FILE.NAM. Under recent versions of RSX-11M you can use the VCP (Virtual configuration program) and the VD: drivers to make block-by-block copies of disks into container files. Whenever possible, do COPY/VERIFY operations followed by a DIFF/BIN to make sure your copy is exactly the same as the original (and that it's readable, too!) >I'll be pulling out a bunch of 11/23 systems on my next trip with some >11/34,35s.

(My >DECNET background was really strong at one point in time but when I saw DEC >dumping I ran to NT like everyone else...) DECNET is fine, if the machine's you're putting together support it nicely. Don't discount the effort it takes to get a PDP-11 properly configured and the peripherals running - sometimes I'm sure you'll get lucky and it'll just work when you plug it in, but when stuff is coming in "unknown" or "not used for many years" condition, it can take time to get everything going happily. Finally, it's really quite easy to get a PDP-11 running RT-11 hooked up and running TCP/IP, so don't waste too much time dinking around with DECNET. >I really don't want this to turn out into a year long project.. Just for some perspective, I've been building the PDP-11 DECUS and freeware archives for over a decade now. It's not that reading any particular medium is slow (I can image several gigabytes of 9-tracks a day while doing other "real" work), but tracking down the material, getting it into my hands (even when I supply my Fedex account number to get it here at no cost to the donator) and indexing and organizing the results is *not* a quick process. If you've any doubts about the mechanical condition of any of your drives, by all means play it slow and don't risk one-of-a-kind media in a drive with questionable heads. And for paper tapes, if you're concerned about mechanical fragility of the tape, find yourself a gentle slow optical reader (like the DEC PR/S01) and don't risk the tape to some insanely high-speed reader (which *will* occasionally jam up and crinkle your tape, even if you keep it properly adjusted.) The name of the game is to preserve and archive for the next 100 years or so, not to rush to get something that isn't as good as the original! If you're going to be archiving DEC OS distributions, you might want to ask me to get you a list of what I've got archived here already. The archive here doesn't go back forever, but I have copies of most versions from the early-mid-80's onward. (i.e. RSTS/E V7 and on, RT-11 V4 and forward with some earlier V3 And V2 distributions, RSX-11M 3.0 forward, and RSX-11M+ V2.0 and forward, with many of the layered product kits thrown in for good measure.) -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

"Has anyone >looked at how old paper should be preserved?" Although it is harder to store, you might want to think about storing it as rolls instead of fan-fold. Old paper tape has a nasty habit of breaking at the creases.

The basic idea is: Expand PDP8.com to a few hundred gigabytes. Find the "module list file - 1959-1984" which I now know contains 55,000 items [I have the total report], index it, and put it online. Hire/buy a microfiche scanner and *attempt* to scan and index the 5000+ sheets of microfiche I have (prints, MDS, IP,tecos,reports, maintenance manuals, software, source code,wire lists, engineering drawings and bulletins, internal tech reports, etc..)... with the help from a few list members. Read in all the software into one standard image format and index on the site. The project will be financed by selling a small portion of the stuff I have received(am receiving)on eBay.

Atari ST Y2k Question

by healyzh＠aracnet.com

OK, I've got someone asking me if there Atari ST's are Y2k. Considering the fact that the only Atari I've got working is a TT030 and I've not touched it in a couple years (can't even get to it at the moment), does anyone have any ideas on this? I don't even remember if you can set the data on a ST. It sounds like a they've got 520's. Somehow I don't think they're up to attempting a TOS upgrade, if you can still get the necessary parts to accomplish that. Somehow I think the best answer for them is to set the clock back. On a related subject does Win95 barf if you've not bothered to set the clock back? Who knows when I'll next bother to turn on my Win95 laptop at work (I use it for about 5 minutes a month, if that).

Upgrading Compaq Luggables (fwd)

by siconic＠jasmine.psyber.com

In case anyone is interested... Please reply to: 70224.3422(a)compuserve.com ---------- Forwarded message ---------- Date: Wed, 29 Dec 1999 00:42:47 -0500 From: K.E. Towle <70224.3422(a)compuserve.com> Subject: Upgrading Compaq Luggables Hello, I just happened across a forum thread that you took part in, the subject of which was the original Compaq "Luggable." These were great machines in their time, and can still be quite useful when appropriately upgraded. Should you have one of these old classics laying around gathering dust, I thought I'd mention that I have a few remaining 80386DX-16 motherboards that are "drop-in" replacements for the original 8088 motherboard. With a Cyrix 486DRX2 chip, it will run like a 80486DX2-32 machine. I can supply instructions on swapping the original monitor for a monochrome VGA monitor that bolts in with only minor modifications, along with numerous other modifications. I'm running Win 3.1 on one of these machines to this day (including sound). Please contact me should you have any interest in upgrading such a machine, and/or forward this eMail on to anyone you know who is still interested.

More likely there are more digits, like 2116, 2114, 2115, 2100, 21MX, 21xx.... Most of the HP1000 CPUs have 21xx numbers as well. The 1000 line was, originally, a bundle of a 2100-family computer with HP's RTE real-time executive; eventually HP silk-screened "1000" on the front instead of "21MX", but the actual model number of the processor (the tag on the back) was still 21xx. There were also the HP2000 time-shared BASIC systems, built out of one or two 2100-family processors. 2100-family processors also found their way into all sorts of big HP test and measurement systems in the very late 1960s and 1970s. For example (note these URLs are *temporary*): http://www.reanimators.org/tmp/8322.jpg - scan of a photo of an 8580B automatic spectrum analyzer; the box at the top of the left rack is an HP2100A. http://www.reanimators.org/tmp/8324.jpg = scan of a drawing of an 8541A automatic network analyzer; the top of the right rack is what an HP2116 looks like, and underneath that would appear to be a drawer, a filler panel, a paper tape reader, and a paper tape punch.

pdp8/11 console cable pinouts

Indeed, it's true. I'd even trade two-for-one to get some 16-sector packs. Would it be worth the experiment to butcher a 12-sector pack into a 12-sector pack and reformat it? 12 sectors = 30 degrees, 16 sectors = 22.5 degrees. The idea would be to patch over eight of the slits on the 12 sector pack and cut 12 new ones (by bisecting the circle several times). I haven't disassembled an RK05 in years (the last time was in 1988 when my boss pointed me at two pallets of drives and asked me to get two working units out of the pile - I got four working and carted home the scrap) - the sensor that detects the slits in the pack is optical, not hall-effect, right?

FS/FT: Tektronix 6130 Workstation

by jimw＠agora.rdrop.com

In the ever on-going attempt to consolidate space in the garage and related warehouse spaces (read that - pay less rent!) I'm offering up another random piece that is lurking about and is not a major item of interest to me. A Tektronix 6130 workstation (circa 1984). I'm not horribly familiar with it, but I'll tell you what I know about it. (going from a Tek brochure) 32016 CPU, 32-bit display list processor, 32081 Floating Point Processor, 1MB memory, 360kb 5.25 diskette drive, 20Mb hard drive, dusl RS-232 interface, IEEE-488 interface, LAN interface, UNIX derivitive operating system (Utek?). Known hardware in the warehouse includes: CPU chassis, console display, graphics display (color I believe), keyboard, (at least one) box full of extra boards and parts, asstd. docs and manuals... I think (but don't hold me to this) I recall seeing a mouse and diskettes somewhere but I'll have to go digging. It was reportedly operational when it came to me a couple of years ago. I've never tried to start it up. This may be a pre-production or engineering model just judging from some of the tags/ID plates (or lack thereof) ...and what do I want from this??? Something interesting that fits in more with my primary interests (PDP-8 stuff is good, or check the 'wish list' on my web pages), or enough of a $$ offer to make it worth my while. (over and above shipping costs, unless you are going to pick it up) B^} So...? -jim --- jimw(a)computergarage.org The Computer Garage - http://www.computergarage.org Computer Garage Fax - (503) 646-0174

IBM 360/370 emulation?

by DSEAGRAV＠toad.xkl.com

Anyone know where I can get my hands on an emulator of an IBM 360/370? Always wanted to meet one, and I'm curious. (Taking a shortish rest from working on the '10. I'm into paging and such now and it's giving me fits.) Failing that, anyone know where to get documentation so I can hack one up after I'm done fighting with E10? Altavista search turns up junk matches (resumes and such) and a couple emulators that have disappeared. -------

At one point (oh, almost ten years ago now) small "adapters" were readily available for a few tens of bucks to let you use true blue IBM PC keyboards on machines expecting AT keyboards. I haven't seen these being sold for many years, but they must occasionally turn up at the usual outlets. Personally, I don't really like the IBM PC keyboards, I'm far more agile with a VT100 or DEC LK201 at my fingertips :-). >ON-Topic_analogy: The phrase "SINGLE-Density" never existed until the >marketing people started calling MFM "DOUBLE-Density". Good point. When did IBM introduce MFM "double-density" MFM 8 inch floppies? I'm guessing 1975 or 1976, based on samples I have here.

I need 72 pin parity simms

by lemay＠cs.umn.edu

Well, another christmas spend repairing and upgrading all my siblings and nephews computers. Very relaxing, actually. And I get to use up all the junk I buy over the year at onsale.com ;) But, my nephews need more ram in their computer. It spends most of its time thrashing virtual memory onto a slow bigfoot hard drive ;) If anyone has some 72 pin parity simms they want to get rid of, I could sure use them. I would need either 4 8Meg simms, or better (ie, 2 16 meg or 32 meg simms would also be great). I have dozens of 4 meg simms, but the motherboard (genuine IBM) only has 4 simm slots... -Lawrence LeMay lemay(a)cs.umn.edu

No... only those OSes which are covered by the license (regardless of how restrictive it is) should be made available for general download. Please do NOT make later copies (in the case of RT, copies later than V5.3) available because if you do, it demonstrates to Mentec that we (the hobbyist community) might not be able to be trusted with what they have made available, which might make them less likely to remove the restrictions. The current restrictions are: 1) Only those operating systems and layered products earlier than specific releases (in the case of RT, V5.3) 2) For us ONLY on the accepted emulators (Supnik and Viking, possible Charon). 3) The license does NOT grant the right to use the software on REAL HARDWARE.

OT?: Illegal Transmitters

Does anybody really believe this unsubstantiated and uncorroborated sort of prattle? The key difference between this and normal "news" is that real stories don't have to mask the names of the participants. While it's possible, stupid as our government is, it's not likely that a legitimate source of legitimate news would report a legitimate story in this way, with oblique references to what should be in the lead, and masked references to individuals and businesses likely to sue.

PDP-10 Freeware Archive now has correct date stamps listed

by CLASSICCMP＠trailing-edge.com

It only took a little bit of effort (notably abandoning the Unix date/time stamp, which doesn't go before 1-Jan-1970 UTC, and switching to a system without so much lossage) to get the date stamps on the PDP-10 freeware archive entries at http://pdp-10.trailing-edge.com/ to be correct. Now, if you go and look at a directory in the TOPS-10 or TOPS-20 categories, you will see the original date/time stamps as on the DECUS library tapes. Take a look at http://pdp-10.trailing-edge.com/www/lib10/0003/ for an example. Thanks to a couple of old-timers who persuaded me that I really shouldn't list the creation dates on these files as being 1999, when this can be off by over thirty years :-) Enjoy! -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

It is possible to take a chunk back out of them... I hope he does it. john http://www.pdp8.com/ >

TRW Report

by jpl15＠netcom.com

Well... pitiful is a good word. I went sort of from curiosity and also because it was the first TRW in the new venue. Not more than 50 sellers showed up... in 15 years I've never seen so few people... but what did I expect? Marvin showed up and had the temerity to actually *sell* some things, whereas I don't think I turned ten dollars the whole day. Nick Oliviero dropped by bearing a most pleasant Xmas gift: a nice RX50 for my uVAX II. Thanx Nick! I, as fate would have it, found a very rare music synthesiser/sequencer combo, [an Oberheim OB-SX and DSX] and bought same... there went all my cash, so I packed up and left before 11:00... as many were doing. The first one in January promises to be a much better attended Affaire. At least the music stuff works.. I have it hooked up in the studio and it's just like 1978... but I'd sure look goofy in bell bottoms and colored glasses... so we'll leave it at that. A pleasant New Year to all of you whose calendar rolls over in the next few days.. I am planning a quiet Evening at Home..... vicarious revelry for me! Cheers and K3WL n3W y3Ar d00dZ! 2K RulEZ!!! wE ArE AlL El!Te... WaReZ 4 aLL.... if you can call a 25-year-old version of Kermit "warez"... ;) Cheerz John

OT?: Illegal Transmitters

by edick＠idcomm.com

Well, since the technology's there to make a detonator out of one of these just as it's there to use a cell-phone to fire a device, I suppose they could be concerned, but the way this information is presented at the '2600' site is quite different from the way it's presented at the Ramsey site.

I probably have a schematic of the panel in the DX11 prints. OK... so fabrication isn't a big deal, but knowing which cable pins get named what is. I mean there's disk registers of various types, but just sticking a gross of bulbs on the end of a cable protruding from the backplane will result in some pretty interesting, but random lights.

I know I've got RT-11 v4 on RK and v5 on RL disks; it's just a matter of slapping together a system with RL drives, RK drives and getting an RL drive on my MicroVAX again for easy data transfer ($ BACKUP/PHYSICAL...)

I even have an RK-11C that would be much easier to debug (not to mention more fun) with a panel of blinkenlights.

IBM 360 and 370 control panels available

by jdykstra＠nortelnetworks.com

Data Sales in Savage, Minnesota has a number of 360 and 370 control panels available. During my search this morning, I found panels from several Model 30's, a Model 25, a Model 44 and a Model 65. They also have a number of 370 panels, although I can't quote models--those machines are after my time :-) Condition varies widely--email me for what I remember about a particular panel. Contact info: Jim Breckner, site manager, (612) 890-9047, <jim(a)lineserve.com>. Please mention my name if you contact them--I would like to go back and take some photos of other IBM gear they've got, and they're more likely to tolerate the inconvenience if I'm bringing them some business. Other than that, I have no relationship to these people. NOTE--These panels are from machines that have already been scrapped, many more than two decades ago. I too would have liked to see these machines in running condition, but given their size, power and air conditioning requirements, etc., I doubt that there would have been very many takers. Does anyone know of any intact and running System 360's? How about System 370's? ---- John Dykstra jdykstra(a)nortelnetworks.com Principal Software Architect voice: +1 651 415-1604 Nortel Networks fax: +1 612 932-8549

FW: VAXstation KVM switching

by baileyj＠whitlock.com

Hello, My name is John Bailey and I am an integtrator of data projection and display systems in Research Triangle Park, North Carolina. I noticed this board on a search for VAX info and thought you might be able to help with a problem I'm working on. I need to control several VAXstation 4000.60 machines with a single keyboard/mouse/monitor. The environment is a telecom network management center with limited space per operator. Do you have any suggestions or know of any hardware that would accomplish this? The regulars (Black Box, Cybex) are no help. If not, do you know if the machines will operate without a keyboard and mouse (once booted), or support multiple connects and disconnects of keyboard and mouse while operating. Any advice greatly appreciated, John B.

I can post pinouts for the group if needed once I >get the full model number. Mine started out life as the 300 baud version, but was "field modified" to 2400 baud by changing some of the timing capacitors. (No crystals here, the baud rate is set by a capacitor and tweaked with a variable resistor.) It was also "field modified" to RS-232 by adding a small circuit board to the 0.1"-pitch header inside. (That was done by me!) The circuitry inside is really quite simple, just plain old TTL and some optocouplers for the 20mA interface. What *I* like about the PR/S01 is: 1. Very portable, down to the carrying handle on the end :-). 2. It doesn't use a bulb, but instead a small array of infrared LED's for scanning. For those who've had to deal with loose bulb connections or dead bulbs while in the field, this is a *real* godsend. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

One odd thing about the prs01 is that the outermost pin on one of the two connectors is in use. It is a no-connect to either the terminal or the interface card (which uses the middle six pins out of eight, IIRC). Thanks, John. -ethan ===== Infinet has been sold.

Here is a varied list of computers (and computer-related things) that were either famous or infamous for various reasons First, the infamous ones Computer with the worst built in hard drive: the ICT hard drive in the early models of the IBM-AT. Computer with the worst system architecture: TI-99/4A. (doubly interpreted BASIC? c'mon TI!) Computer with the worst keyboard: (tie) Sinclair ZX-81/Timex Sinclair 1000 & IBM PC Jr. Computer with the worst pitchman: Bill Cosby. (TI-99/4A) Computer with the most limitations: Timex Sinclair 1000/Sinclair ZX-81. Slowest computer: COM-X 35. Computer with the slowest disk drive: Commodore 64(C). Heaviest laptop computer: Apple Macintosh Portable. Most infamous computer by price: Apple Lisa. And now the famous ones Computer with the best keyboard: (tie) Commodore 64(C), & TRS-80 Model 12. Computer with the best speech synthesizer: TI-99/4A. Most famous "vaporware" computer: Xerox Alto. Computer with the best sound hardware: (tie) TI-99/4A & Commodore 64(C). Computer with the coolest pitchman: William Shatner. (VIC-20) Computer with the coolest case design: TI-99/4A. (The case reminds me of a Delorean. Remember those?) Computer with the best introductory commercial: Apple Macintosh. ("On January 24, Apple will introduce Macintosh. And you will see why 1984 won't be like "1984"".) This is all that I can think of. If you can add some more categories or correct some of the entries, please do so! After all, the above entries are only based on opinion (namely my own). ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

>>Computer with the best speech synthesizer: TI-99/4A. > Dunno 'bout that... how about the Digitalker as used on some S-100 systems? You'll note that his definition of "computer" didn't include S-100 systems (probably because they don't have integral video...). But if we have to talk about the "best" speech synthesizer of the day, I'd vote for the original DECtalk (often confused with a VT240 base!) These are still in continuing commercial use at the far end of those applications where you dial in to check your bank balance, etc. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

>Here is a varied list of computers (and computer-related things) that were >either famous or infamous for various reasons (Bunch of IBM PC - TI-99/4 - Timex/Sinclair - Apple - Commodore - RS stuff deleted for brevity). Replace "computer" with "desktop microcomputer with keyboard and video display" and I'll agree that your list makes sense. (Though the Alto doesn't quite fit that category.) Unfortunately your list completely neglects the non-desktop micros, especially those without integral video, minis, and mainframes... Tim.

RC 702

by rachael_＠gmx.net

Hi I have just got a old Danish build computer from 1979, it was build by Regne Centralen. I got it including a RC 722 keyboard and a RC 752 monitor. It`s based on a Z80a with 64 Kb and two fullsize 5 1/4" floppy drives build by YE in Japan. I did not get any discs with it and no one seems to remember it here in Denmark, so I was hoping that somehow some of this machines has made it outside Denmark, so if anyone knows something about this machine please step foreward.

Time is relative

They couldn't say "this > year is 45 BC'" because they didn't know when it was going to happen. Time is relative. The Egyptians had their own calendar, it would be 5XXX now. I rather like the Mayan interlocking circles. Their calendar was more accurate than ours. It is also interesting that it had a start time that preceded their own culture. I suspect that for most of humanity that the stars and the night sky has held a far greater position in ones life than now. We used to live a lot closer to earth's cycles. The seasons and passing of years generate their own calendar. We, in Oregon, are going through a long term cycle of heavier rainfall, more than 18 years long. People seem to forget this is a 'cycle' in the dry years. I wonder what the native American cultures called "EL Nino"? I am sure it was a segment of their calendar. Mediterranean metalsmiths(in Rhodes, 86BC) built a differential geared calculator for calculating the positions of the sun and moon, with eclipses, multiple years and more. Here is a URL which may have appeared on this list before. http://www.math.utsa.edu/ecz/ak.html <A HREF="http://www.math.utsa.edu/ecz/ak.html">Gears from the Greeks</A> I hope this qualifies as "on topic" Many cultures instituted their own calendars. Western civilization has instituted the current calendar, mostly for commercial purposes. Since most people have adopted it, the current calendar would be hard to change. This is the same problem with the millennium change. I like the British Observatory's statement. The idea of a year of celebration sounds like a lot of fun, I hope to do my share. Paxton
