<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).

DEC MMJ serial cables

> I'm also in need of a serial cable that has the funny "offset rj11" plug > on one end and a standard DB25 on the other... so any pointers will be > appreciated. The connector is called (by DEC) a "MMJ plug" and they're available through big electronics distributors (such as http://www.digikey.com/ and http://www.mouser.com/ ). If you don't want to spend the bucks on a bag of MMJ plugs and a MMJ crimper, I also sell complete MMJ cable assemblies. The most popular ones are MMJ to DB25F for connection to a terminal and MMJ to DB9F for connection to a PC-clone's serial port. See http://www.trailing-edge.com/www/mmj.html for ordering information. -- 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

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.

YOU BETCHA!! Stay tuned for more information or contact me to find out how you can participate http://www.vintage.org
