Homebrew projects wanted for exhibit at VCF 3.0

by maxeskin＠hotmail.com

How about building an 'information appliance' toaster, like Microsoft wants you to? For purely parody purposes, of course. Maybe I'll do something like that. Maybe it will have a network card, and I'll demonstrate toaster operation with CGI scripting. And put up a toastercam.

Any *really* homebrewing going on?

by CLASSICCMP＠timaxp.trailing-edge.com

>Homebrewing is still going on. Its just not as prevalent any more because >each year the art dies a little more. I think the tales of homebrewing's demise are being a bit exaggerated. Certainly, the character of homebrewing has changed greatly over the past 20 years. It is true that some of today's tools of the trade - for example, a good PAL/GAL programmer - are more expensive than many of tools of 1975. But in real dollars, today's $800 device programmer is much cheaper than, say, an 8080A CPU, which had a street price of US$250 or so in 1975. And many folks are doing very interesting things with programmable devices. You can get into PIC programming for well under $100, and there's lots of really interesting things you can do with that. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817

If you don't mind making about a 15-year advance in the electronics you'll be using, you might also seriously consider making a CPU via the state machine route, using an EPROM and some counters. All math and logic operations can very easily be done via table look-up in the EPROM. This is a rather common assignment in lower-level computer engineering courses, as it's something that can be easily wire-wrapped in an afternoon or two, and it is extremely easy to try new microcode revisions. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817

BA123 Power Supplies

I have some complete BA123 supplies here. I also have 4 BA123 chassis that are on my trailer that is heading for the scrap dealer.

Last night I left the PDP-11/23+ (still haven't gotten it to work with a /73 CPU board) running for about 4 hours to see how it handled being left on. The only thing running was "show mem" on the console since I was working on some other stuff. Much to my terror/irritation, about 10pm I noticed a buzzing or sparking sound. I quickly moved it away from the sofa, and started investigating. It sounds as if something in the area where you've got the breaker and the powercord plugs in is 'arcing and sparking'. I've got to take off in a little while, but I plan on looking into this later this afternoon or tonite. Unfortunatly I don't have any docs on the BA123 (just the BA23), so will be having a fun time figuring out how to get it apart. Does this problem sound familiar to anyone, and does anyone have any suggestions? Zane | Zane H.

New to the list

by Aaron_J_Hayden＠student.ferris.edu

Howdy all, My name is Aaron Hayden and I have recently joined the list. Currently in my collection I have a C64, a PC Jr., a Hero robot and my trusty 486-66. I enjoy using the older systems and in some cases I think they're a bit more user friendly (at least for me). I was looking for some info on my PC Jr. and found the list. I'm sure I'll gain some knowledge and hopefully give some too. Which brings me to my first question... I was just recently given the PC Jr. however it seems it doesn't work. I have only plugged it in a couple times but haven't looked at it much more than that. I also do not have any documentation on it so I'm flying blind. When I turn it on the screen turns all grey. Anybody have this problem before? It has been sitting for a while but worked fine until it was boxed up. It came w/ two power supplies so maybe their both bad? Any ideas? thanks in advance. Aaron

No subject

by Aaron_J_Hayden＠student.ferris.edu

Thanks for all of the responces. They're very much appreciated. At any rate, while attempting to keep my first message short I left out some important info. So we'll see if this clarifies any? I have a 4863 monitor (which does not use the RCA plug). This computer has two floppy drives and two cartidge slots. Which slot is primary? The left I assume. With the machine I got a BASIC cartridge, three DOS 2.1 disks, and a couple DOS 3.21 disks. However, I don't think the computer is trying to boot. That is, it's not reading the drive (red LED doesn't light). I didn't get any manuals with it, although I'm sure I have the monitor plugged in right. It only can go in one plug, one way. The keyboard however, can go in a lot of places, but which one? It came w/ two power supplies and the computer acts the same with either one. (I have not had a chance to check them with the info I've got so far). I do not have a logic analyser (but I do have a RCA signal generator used to work on t.v.'s if that can be used i n any way). Again, thanks for the help and I hope this info helps too. Aaron

ESDI, MSCP, RSX11M, TK50's, etc.

by CLASSICCMP＠timaxp.trailing-edge.com

>of my parts and tapes. I discovered that I've got two ESDI controllers, >instead of the one that I knew about, one is a Emulex QD21 which I found >the manual online for, the other a "Webster WQESD" which I have the manual >for. Which version of WOMBAT is on your WQESD? You can identify this by either looking at the sticker over the firmware EPROM, or if this doesn't tell you, by starting up the on-board diagnostics. Certain versions of Wombat do not interact well with RSX-11M's DU driver. Very often, older versions will work better than certain newer versions. Most of my systems are running WOMBAT V2.3, which works fine for me with the PDP-11 OS's (but *not* with later VMS versions.) WOMBAT V2.3 does work a little strangely with 2.11BSD's MSCP driver when you do a "shutdown -r", having something to do with the CPU doing a bus reset while the controller is still doing a write. I've never attempted to compile a list of which versions of the PDP-11 OS's do and do not work with various WOMBAT versions, but perhaps it would be worthwhile to build such a table. As it is, I just pop in different firmware EPROM's until it works. It's also worth checking that the WQESD really does respond to the CSR you think you've set it to. The table in your manual is probably correct for the most common address configuration PAL, but there are several dozen different address configuration PAL's that were made for special applications. If you have one of these non-standard PAL's, you'll probably be much better off to put the WQESD at 17772150 and the floppy controller at some other CSR. --- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817

Damn

Came close to finding the cable for my laptop by instead found some audio cables that probably belong to either Rax or Roger. I'll be in SF next so I'll try to bring them and drop them off with Roger since I know about where he lives. Can Rax and Roger please check their audio gear and see if my laptop cable got mixed in with some of theirs? You'll know it when you see it: normal wall plug on one end (three-prong) and a funky three-prong on the other that looks like it can't belong to anything but a stupid Compaq laptop.

Guardian article

by dastar＠ncal.verio.com

Here's the Guardian article for those who were interested in reading it. Copyright 1998 Guardian Newspapers Limited The Guardian (London) October 1, 1998 SECTION: The Guardian Online Page; Pg. 4 LENGTH: 739 words HEADLINE: Not just any old iron;A festival of vintage computers threatens to rewrite computing history. Karlin Lillington reports BYLINE: Karlin Lillington BODY: Computing history is clear - microprocessors were invented by three engineers at Intel in 1971. Or were they? That notion was disputed in a press conference at the Vintage Computer Festival in Santa Clara, California on Saturday, when an obscure computer consultant from San Jose revealed that he initiated work on a secret onboard computer for the US Navy's F-14A TomCat fighter jet that contained a chipset comprising three microprocessors and three support chips - in 1968 (and completed in 1969). According to 53-year-old Ray Holt, the Navy has only now released documents allowing him to publish the details of his work. Holt read out an analysis >from a former chip designer for Motorola, Russell Fish, which stated his belief that, had the microprocessor design been made public in 1969, it would have advanced the industry by five years. However, two of the Intel engineers involved with the creation of the 1971 microprocessor, Ted Hoff and Federico Faggin, have already disputed the claim in a Wall Street Journal article, centring on the correct definition of a microprocessor (six chips should not qualify, according to the two). Whoever deserves the laurels, the achievement of Holt and his small team was astonishing for its time. In today's world of finicky microprocessors, which overheat easily, the chips in Holt's F-14 could function at the temperature of boiling water - in a range of -55C to +125C. Because of size and weight restrictions for the F-14, the circuit board was an extraordinary 6 by 4 inches for a highly sophisticated flight computer that analysed and controlled altitude, angle, speed, missile systems, positioning of the movable wings, and other functions. Machines of similar power at the time weighed 300-400 pounds. 'I think as computer designers and people interested in history, we need to know this happened,' says Holt. 'That back then, we could do this.' Other hardware at the show at least enjoyed a moment of fame - however fleeting. Who now remembers the MAD Computer, the Sol, the Exidy Sorcerer or the Czech -designed Tesla 780, which used a TV set as its monitor? Most people might see the machines as just back-of-the-garage dust magnets, but hardcore computer buffs were entranced by these footnotes to the history of computing, lovingly displayed at the show. Organised by a Sam Ismail, a goateed, hyperactive young programmer who started his own collection of 200 machines 11 years ago at age 17, the festival attracted several hundred devotees. The kind of person who thrills at the mention of the Altair, the kit-built, embryonic personal computer from 1975. Some came for the computer flea market, others to hear such speakers as computer designer turned Microsoft researcher Gordon Bell (who admitted during his talk on the prehistory of personal computers that he proposed to his wife using a program he created at DEC). But the festival's soul lay in the impromptu museum of geriatric hardware. Sitting among neat rows of his Commodore PCs, exhibitor Larry Anderson explained the motivation for collecting what others send to the landfill: 'Nostalgia. This is the type of computer I went to school and used,' he says, caressing the metal casing of a 1977 Commodore 2001 series PC. The machine boasts 4 kilobytes of memory - in comparison, computers today routinely come with 4,000 times as much. 'Chips were so unreliable that the Commodore came with a spare,' says Anderson, pointing to an extra chip taped into one corner of the box, like an extra coat button. The manufacturer warned that chips frequently came loose and needed to be pushed back down. The Atari manual, he says, actually recommended dropping the machine from three to four inches if it wasn't working properly. Nearly every species of computer basked in visitors' attention: the 1975 prototype Apple I, screwed onto a piece of plywood by Apple founders Steve Wozniak and Steve Jobs; the first IBM PC, and the first Sun micro computer. The crowning event was the Super Nerd computer quiz, covering such categories as computing acronyms, computers in the movies and 'Nerdpourri'. Ismail conducted the entire quiz - to much general admiration - from behind the green -screen glow of an Apple III from his collection. Ray Holt's paper on the F-14A computer's architecture is at www.microcomputerhistory.com The Vintage Computer festival is at www.vintage.org/vcf/ Sam Alternate e-mail: dastar(a)siconic.com ------------------------------------------------------------------------------- Ever onward.

Can anyone identify this vax for sale on Ebay?

Right... >< I am not suprised. Although there's a PDP11 CPU in there, the I/O ><system and interrupt structure is nothing like any other PDP11... > >the primary thing was the memory mapped video. the PDT-11 also had >strange IO. The PDT-130 and -150 both used the same device driver (PD), though they would display as different device codes, if I remember. The interesting thing about them was the fact that the firmware knew about RT-11 queue elements, so all the driver had to do was take the queue element and pass it to the ROM, which handled the IO, returning if there was an error, or when the request was satisfied. The driver then returned to the monitor the completed queue element. The PDTs were also interesting in that they used an 8085 (later an 8085A) to handle the IO page. Word accesses were about 90ms, byte accesses were about 180ms if I remember correctly, and we had to avoid any read-modify-write instructions (BIS/BIC) otherwise it would take twice as long as the 90ms/180ms... Finally, an interesting point, the PDT-11/110, which had no storage devices, had code in ROM which understood the same protocol as the GT40 for downloading code... Somewhere I have a program I wrote for use at a science fiction convention (worldcon-1980, in boston) where I used a PDT-11/150 to download a GT40 with various programs like lunar lander or roses, or bowling, etc...

FS: Apple Lisa System on Auction

by gmast＠polymail.cpunix.calpoly.edu

I was a member of this list for quite a while but the mail load got to be too much for my school account. I have placed an Apple Lisa 7/7 on the eBay auction recently. The bidding ends on Sunday the 4th of October. It's a nice system and I posted a ton of pictures at my page: http://www.calpoly.edu/~gmast/sfs/lisa/lisa.html The bidding hasn't been that great so I think this system will go for a good price. It will sell regardless. If this post offends anyone, I apologize but I know some people here might want one of these for their collection and this might be a good opportunity. For more info, check out the auction listing at: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=32694351 and check out the pictures at the link above. The bidding must take place through the auction now that I've listed it. Bidding is free but you must register with the auction. Thanks, Greg

VCF mentioned in UK newspaper

by pjoules＠joules.enterprise-plc.com

There was write up of the VCF in todays Guardian, it included a picture of an Altair and a wooden Apple, along with an account of Ray Holt's talk. It also says the it was organised by "...Sam Ismail, a goateed, hyperactive young programmer who started his own collection of 200 machines 11 years ago...". Is this a fair description Sam? ;-) Regards Pete PS Congratulations, Sam, on what seems to have been a very sucessful event.

Universal drive

by kaikal＠MICROSOFT.com

Nothing universal. Let me break this down by type: CP/M and Related Formats: Teledisk will read most CP/M and related formats on double-density (MFM) diskettes. Standard IBM PC floppy controllers are physically unable to read single-density (FM) formats (for some reason, even though the Western Digital chip they used supported FM, they never connected the pin. The Teledisk folks have some instructions to modify old IBM controllers). Teledisk can also read CP/M and related formats on FM diskettes with an appropriate floppy controller (e.g. CompatiCard, or modified IBM controller). Some CompatiCard versions will also allow connection of 8" drives to an IBM compatible. If you find a CompatiCard for sale, buy it. Non-CP/M Related, Non-Apple Formats: Teledisk does not read other FM formats that are not similar to CP/M (e.g. TRS-80 Model 1). I'm not aware of a solution to read/write formats such as TRS-80 Mod1, Coleco, Atari 8-bit, etc. Later TRS-80's like the Model 4/4P can read TRSDOS diskettes and copy the files to CP/M format which could then be read with Teledisk. Apple II: There is no physical way to read an Apple II diskette on IBM floppy drives. There are 3 solutions: 1) Use a Trackstar 128 card in an IBM compatible; 2) use a //e emulation card in a Macintosh LC series, then copy to PC format if necessary; 3) Copy the 5.25" Apple DOS files to 3.5" ProDOS format on a //e equipped with 3.5" and 5.25" drives, then use an old Apple File Exchange on a Mac to read the ProDOS disk. Macintosh: All Macs with SuperDrive/FDHD drives can read/write PC format. To read Mac dual-density format on the PC, you can either copy the files to PC format on a newer Macintosh (be SURE to keep the disk write protected or the newer Mac will automatically screw it up so it won't read properly on your old Mac!) or you can use a Central Point Copy II Option Board Deluxe on an IBM compatible. Others: Atari ST uses DOS format in the first place. Amiga can be read on the PC by Amiga emulators. C64, I have no idea, but I know at least you could use a C128 to copy files to CP/M format. NOTE that if you don't want to actually access FILES, but just want to COPY the disk, all you need is a Central Point Option Board in an IBM compatible. I use my "Compaq Computer" (a.k.a. Portable I) with an Option Board to copy any SD/DD format, including Apple II. Kai -----Original Message----- From: Max Eskin [mailto:maxeskin@hotmail.com] Sent: Thursday, October 01, 1998 4:36 PM To: Discussion re-collecting of classic computers Subject: Universal drive Is there a device that would allow _any_ disk, independently of format, including Apple ][ disks, to be read?

< > this for all conventional formats, but not Apple disks. It would be < > nice to connect one of these and read the disk image into a file. < > The main reason why I ask is for rescuing messed up floppies... Apple used GCR coding for their drives and there are no commonly available chips that do. In fact the apple does not use the traditional floppy disk controller chips at all. The FDC logic on the Apple is rather simple and the CPU provides the brains as a software FDC. It was part of the idea of using software to replace hardware to make the machine simpler and less expensive. < PCs use a disk controller chip based on an NEC 765 design that can not < read ANYTHING other than MFM (some can also do FM), with IBM 3740 style Excuse me! That is patently incorrect! If you qualified that as *most PC controllers cannot read some formats* that would be true. The 765 and all of the chips based on the 765 core can read FM encoded disks. It's not always possible with PC based designs as some are hardware crippled (sloppy data sep circuits) and most of the PC bios code is marginally brain dead. However the 9266, 37c65 and 92c665 have been seen doing FM. In the mean time my S100 card design and the compupro DISK1A both happly read 8" SSSD (FM) disks and even single density 5.25 media. < The Western Digital disk controller chips (179X, before they changed ove < NEC style) could do a reasonably real track read of anything MFM < regardless of sector header structure. Try the 765 read diagnostic command. Hex 02 (fm) or 42 for MFM. <They were used in TRS-80s and a LOT of machines OTHER THAN PC. The TRS80 used the 1771 that was FM only. the WD 177x or WD179x still cannot read an apple disk. Allison

Need info on Teletype

by g＠kurico.com

Just picked up a couple of terminals. A Teletype 3320 and (from memory here) DECWriter III. Any information on the teletype would be greatly appreciated (like how to interface to it, it has some small centronics type connector on the end of the cable). As for the DEC, I'll give it to anyone who wants to come pick it up in the Central Texas area (Austin specifically). It's untested and the best I'd be able to do anyway is to see if it powers up. I'll give it about a week before I trash it unless someone can convince me otherwise. George

Xerox 16/8

by Innfogra＠aol.com

In a message dated 98-10-02 13:36:17 EDT, you write: << Answering an ad for a "Xerox 16/8 Computer," I found out that the computer was actually an 820 II that was in possession of a Xerox employee prior to the seller. He (the seller) told me that the 820 was upgraded to be "just like" a 16/8, and judging by the haphazard looking innards (things jammmed into slots, tape holding things together, etc.), I think I believe him. I also got 3 or 4 binders for a 16/8 computer but all the pictures inside show a standard looking PC style desktop case. Which is the "real thang?" >> The answer is both. Most 16/8s that I have seen are 820 IIs that have been upgraded to 16/8s. This explains the tape and wires. At one time I had gotten the upgrade kit myself. I never installed it because I found a factory 16/8. It looked just like my 820 II with a different bezel. When the IBM PC was introduced the market for these dropped considerably. Xerox was selling into the business market at about a $2000 price point. It was adapt or die. Xerox redesigned the case to look like the new PCs. Printed new manuals. They died anyway The winds of change were blowing. If you find one of the PC versions of the 16/8 save it. There are very few of them. Most of Xerox's production run was remaindered. I saw them surplus for a couple of years. I bet most of them were scrapped. I have never seen one with the PC style case. I have manuals with pictures too. You may be right on the drive interfaces although all the drive boxes use the same 50 pin plug. I would have to do some research. Paxton

Fried PDP-11 -> Panic Mode Off

by healyzh＠ix.netcom.com

OK, it just booted. The only difference was I turned the VT420 off, and the BA123 had been sitting powered off while I wrote my panic message. I decided to give it one more try before crashing for the night in dispare. I'm totally confused. Either it needed to sit for a few minutes, or the terminal needed power cycled. Or maybe it was waiting for me to panic and act foolish :^) Argh! Ideas? Zane | Zane H.

I think I fried a PDP-11

by healyzh＠ix.netcom.com

OK, I had the PDP-11/23+ board in place, and the system loaded up. I was testing out the memory boards I've got by swapping them in. It didn't seem to like a pair of clearpoint memory boards I've got, and then I put in the M8637-EC board, and NOTHING works. It won't even come up with the info on the /23+ ROM. I've a very bad feeling about having put ECC RAM in it. I went so far as to pull out all the boards, nothing. I swapped the /23+ with a /73 and still nothing! What on earth did I do? The diagnostic LEDs on the /23+ are D1, D2, and D4 unfortunatly the manual I've got on the board doesn't seem to explain what the LEDs mean. It's as if I managed to fry the backplane, but that really doesn't make sense. Zane | Zane H.

It would have to be PC-DOS 2.10. Version 2.11 was MS-DOS i think. I have a copy of 2.10 on the shelf with the book. I don't know anything about PC Jrs though, with the exception of a thrift store here in Portland, OR that has a monitor for one. If you are interested in the SW contact me directly. I was actually looking for DOS 1.XX to see if I might have it. I don't but I ran across the book set marked 1.01 for the 3270 PC. I got excited but what was inside was PD-DOS 3.0. Oh well, such is life. I have lots of versions of PC-DOS 3.0 & 3.1, and a couple of MS-DOS 2.11 for other computers that I am interested in unloading. Any interest out there.

Apple <> Orange 386?

by Innfogra＠aol.com

Hi Joe; Nice find. Almost any NEC multisync momitor will work. There is a adapter that goes from 9 pin to apple for the older multisync monitors and another 15 pin to Apple for later monitors. I can get them here in Portland, Oregon at Oregon Electronics. You should be able to find a cable house in your neighborhood that has the adapter or a cable that would work. Other monitors like the Sony should work also. Paxton

Xerox 16/8

by Innfogra＠aol.com

The Xerox 16/8 is a desktop CPM Computer of the mid 1980s vintage. It has both 8 and 16 bit processors in the cabinet. I believe the original computer was based on the UK Big Board design. The 16 bit processor is on a propriatory add on card. It runs CPM-80 & CPM-86. If I remember right it will run an early version of MS-DOS. It has been years since I have run mine. My 2nd computer was a Xerox 820, an earlier model. I was delighted when I got a 16/8. It uses external drives which you may not have gotten. The disks availiable were dual 8" floppys, dual 5" floppys or a 8" Floppy and 8" HD. You could use only one set at a time. Brian of Emerald Microware (business no longer in existance) in Beaverton, Oregon made a data sharer that would alow you to hook up both 5 & 8" drives at the same time. He supported this family of computers for many years. It was a nice machine. There are two styles of keyboards, the original which is bulky and a low profile which uses a different ROM. The basic computer consists of three pieces, the Monitor/CPU, a keyboard and a drive cabinet. I have docs, drives, cpus and parts if you want to communicate with me directly.

IBM XT286

by kaikal＠MICROSOFT.com

It is IBM's clone of the PC/AT with a few exceptions. Hmm, I'm sure you don't mean "IBM's clone of the PC/AT", since IBM could hardly clone their own product. The XT-286 is actually a warmed-over PC-XT motherboard design, adapted to use the 80286 CPU. It was a product positioned in between the XT and the AT in IBM's lineup. 3. Some AT boards will not fit into it. Actually, no AT boards will fit into it. Although it used the AT's 286 CPU, it retained the XT's 8-bit bus, and was limited to 640K RAM (no 16-bit RAM expansion available). In a sense, you can almost think of it as a "286SX", since it is largely analogous to the 386SX in that it had a bus half the width of the CPU internal core (although I'm not sure whether the motherboard RAM was 8- or 16-bit). The XT-286 failed, not just because of its limited expansion versus the AT, but due to competition from the Turbo XT (8-10MHz 8088/NECV20) market, which had similar performance.

I have an XT/286 in a box and used it for many years. It is IBM's clone of the PC/AT with a few exceptions. 1. It uses an XT case 2 It is 6mhz with 0 (zero) wait states. 3.

I have recently came into position of an old Xerox computer that I really do not know much about and was wondering if anyone out there would be able to send me via e-mail any info that they may have on it. The computer works and all but all that comes up is something about tables and something about invalid drives. If anyone out there has any info on this computer I would greatly appreciate it.

Ah, I got the answer... there was a 1.01 with a limited release in the US only, I still have yet to get confirmation over whether there was a retail store package or whether it was bundled only. 1.03 was indeed the first multinational release about 9 months later.

Unless this was a pirated version smuggled out of MS or an elaborate put-on it must be the first issue. It has a somewhat-Norton Commander style desktop but has most of the utilities of the later version - notepad, write, calendar ,etc. and a pif-editor and win.ini. It comes on 5 360k disks with a set-up program that builds a small Win.com and an much larger overlay binarie. As you mention it doesn't support VGA and the readme file has a lot of references to problems with AboveBoard (the Intel mem-expansion card). I've had it for a short while and just now installed it on an 8580 PS2 running DRDOS. While I can get the desktop the utilities hang with the familiar hourglass. I just tried it on my 5150 which has an Inboard card and uses the A20 handler but only 1meg memory and also heavily configured and with Dos 5. It crashed leaving me at the prompt. Using my favorite shell CMFiler got me to a blank screen before crashing . Likely memory related. I'm going to try it on one of my 286s' using an earlier dos and with one of 1.01's memory handlers emm.at or emm.xt (dated 7-30-85) in autoexec. I have of course no manual.

ESDI Cabling

by Marty＠itgonline.com

The 34-pin control cable for ST-506 interfaces can either have a twist or be straight through where you need to alter the HDD drive selects accordingly. The 34-pin control cable used on ST-506 interfaces doesn't care whether it lives in a PC PC/XT or PC/AT environment. Marty ______________________________ Reply Separator _________________________________ Subject: Re: ESDI Cabling Author: classiccmp(a)u.washington.edu at internet Date: 10/1/98 3:55 PM > The only thing in PCs I know of that use a twist cable is Floppies. The AT MFM disk control cable (for ST506-like hard disks) certainly has a twist in it. This twist swaps over 2 of the drive select lines between the 2 drives, so they can both be set to the same drive number. I will have to get the manual if you want the exact details. I think the XT control cable does as well.

KL-10 Emulation Underway

by DSEAGRAV＠toad.xkl.com

This message was supposed to have gotten here a while ago, but it never did. Myself and a few other individuals are actively working on a KL-10 emulation. The project is named e10, and is 3.99% finished. I'm busy confusing myself with 36-bit math right now. Anyway, help would be nice to complete this fscker. It's being written in C for Unix platforms, it's under the GPL. Please don't email me and tell me how stupid this is, or how I'm never going to finish, I'm trying my damndest to maintain the Never-Give-Up attitude. I plan to be winning by Y2K. Anyway, does anyone want to help out? I generated a web page (Using vi, of course...) at bony.umtec.com, and the current source can be had from there via FTP in /pub/ka10/*. Any help at all would be appreciated. -------

ESDI Cabling

by Marty＠itgonline.com

ESDI cabling is definitely the ST506/412 interface used on old MFM (e.g. Seagate ST-225) or RLL (e.g. Seagate ST-238). If the 34-pin control cable is straight through (without the twist) select drive 0 if the selection is 0 and 1. If the selection is drive 1 and 2, select drive 1 (nomenclature varies among manufacturers). Ensure the terminating resistors are installed or you are asking for trouble. If the 34-pin control cable has a twist and you have only one drive attached to the end of the cable with the twist, use drive select 1 if your drive nomenclature is 0 and 1. If the drive select nomenclature is 1 and 2, select drive 2 and make certain you have the terminating resistors installed. Two drive scenario: 34-pin control cable with twist, drive at end of cable with twist use drive select 1 if drive has 0 and 1 as drive selects or 2 if using 1 and 2 drive selects and again ensure the terminating resistors are installed in this drive. The drive in the middle of chain should use drive select 1 if drive has 0 and 1 as drive selects or 2 if using 1 and 2 drive selects (yes, use the same drive select as the C: drive attached to the end of the cable) and make certain the terminating resistors are removed from this drive which will be seen as D: drive. If the 34-pin cable has no twist, C: drive is set for 0 (if drive selects are 0 and 1) or 1 (if drive selects are 1 and 2) and connected at the end of the cable with the terminating resistors installed; D: drive is set for 1 (if using drive selects 0 and 1) or 2 (if using drive select 1 and 2), connected in the middle of the chain and must have the terminating resistors removed.

Wang Thang Revisited

by lwalker＠mail.interlog.com

In trying to finf info re my Wang , Wang Users Group turned up empty, so I did a general search on "Wang". What fun. I found out there's a hell of a lot more Wangs than Jones out there. And a good proportion of them are scientists. Wangs like to display themselves and one even had pictures of his wife and his sister on his page. Among the Wangs on display were Joy C Wang, Junping Wang, Leiping Wang, Linping Wang and the saddest, Weiping Wang (maybe a pseudonym for linping) There was Gang Wang and Wang Man but the most impressive Wang was : Wang Jinrey a fighting philosopher Nationality China Fighting Style shin-irokugoken Age 84 Height 165cm Weight 56kg Bloodtype B I was especially impressed that they included this fighting philosophers blood type. I also found out that bin wang wasn't a binary file and wang fan wasn't a computer enthusiasts group. There was also a geographical perspective with the Phuket jewelry shop in Wang Talang Siam , the King Wang Hotel in Taiwan, and the Wang Centre for the Performance Arts in Boston. There's also a Wang differential geometrical theorum used wildly by scientists. Then I dicovered I could finger wang@risc and after 60 Lycos pages of URLs with nary an end in site ,my energy petered out I was getting giddy and laughing hysterically at every Wang thang . There's just too damn many Wangs out there and I exited without finding any references to my Wang.. On a less humorous note I did find a UK source for Wang and NEC as well as other laptop batteries. MDS Batteries. Likely pricey to ship them this side of the pond but they did have some specs so maybe one could make yer'own. ciao larry lwalker(a)interlog.com

It boots from ESDI <finally>

by healyzh＠ix.netcom.com

Good grief what a week this has been, but I finally got the PDP-11 I'm trying to put together to boot off of a ESDI harddrive. Not the processor or disk controller I was expecting, for all that goes not the version of RSX-11M I was expecting, but it's up and running. At the moment it is running a PDP-11/23+ instead of the /73, has a RLV12 in it, and is missing basically all the boards. However, tomorrow I'm hoping to basically get the hardware back into the configuration that I want. I had two problems. First, for some reason I couldn't get RSX11M to like the Webster WQESD controller I was trying to use, so I switched to a Emulex QD21, and was able to load the TK50 onto the Harddrive. But it wouldn't boot once I got that done last night. Foolish me thinking it wasn't bootable drug a RL02 drive and controller into the house tonite :^( Turns out that I'd gotten the DIP switches mixed up <ARGHHH> Once I had them right (and the system totally rearranged) it booted off DU0: despite my wanting to go from DL0: :^) If work doesn't interfere tomorrow night, I'm going to be having some fun with this system :^) Zane | Zane H.

DECsystem-1090 (KL10) power requirements

by eric＠brouhaha.com

Questions came up last week about how much power a DECsystem-1090 CPU (KL10) consumes, and how the power supply works. Tony Duell suggested that the KL10 might not consume any more power than a big PDP-11/45 system; I disagreed. My previous description of the power system was not entirely accurate, so I've dug out some technical documentation, including the manual "Power System (1080/1090) Interface Description", part number EK-PWR1-ID-002, dated March 1977. The KL10 CPU cabinet consists of three bays. In a 1080 or 1090, the middle bay contains the main CPU card cage, which has 47 extended hex modules full of ECL logic. The left bay (as viewed from the front) contains an I/O card cage containing up to 50 extended hex modules full of TTL for the RH20 Massbus channels, DTE20 front-end interfaces, DMA20 memory bus interface, and DIA20 I/O bus interface. The right bay contains a PDP-11/40 front end processor, a TU56 dual DECtape transport, and a TC11 DECtape control. Note that this does not include any memory or peripherals necessary to make a complete system. I am going to describe only the power requirements of the CPU cabinet. All KL10 models require three-phase power. The KL10-AA and KL10-BA models operate on three phases of 90-132 VAC 60 Hz (208 VAC nominal phase-to-phase) The KL10-AB and KL10-BB operate on three phases of 180-264 VAC 50 Hz (416V nominal phase-to-phase). Total input power is specified as 12.6 kW typical for a basic system; a real-world configuration would have more DTE20 and RH20 units, so it would consume more power. Needless to say, the power supplies in the KL10 are not power factor corrected. The 863 three-phase power control has a 75A main circuit breaker. Unfortunately I do not have a copy of the DECsystem-10 Site Preparation Guide, so I don't know what the actual specifications for peak current per phase are. With the exception of the power supply for the main CPU cage and the cooling fans for that bay, most of the machine actually operates on single phase power. The various fans and power supplies are distributed between the phases to balance the load. The CPU cage fans operate between two phases (208V) in the -AA and -BA models, and between one phase and neutral (240V) in the -AB and -BB models. The power supply for the ECL consists of an H760A or H760B raw power supply (depending on the line voltage), a 70-09475 capacitor assembly, and an H761 regulated series pass assembly. The H760A/B contains three ferroresonant transformers with primaries wired in a three-phase delta. The secondaries are center-tapped and wired with half-wave bridge rectifiers. The output is -12V at 490A. The diodes are mounted to a massive heat sink with its own fans. The capacitor assembly consists of thirteen 0.3F capacitors in parallel for a total capacitance of 3.9F. The output under full load is -11V+-10%. In the event of a power failure, this is sufficient to allow a hold time of 20 ms before the voltage drops below -7.5V. The H761 regulated series pass assembly consists of 13 linear regulators. Nine have -5.2V 35A outputs for the ECL main power, and four have -2V 35A outputs for ECL termination. There is room for a 14th linear regulator which is normally not installed. The maximum load for the CPU card cage is thus (9*5.2V*35A)+(4*2.0V*35A), or 1918W. At that load, the input power required by the power supply is over 5460W. This is less than 35% efficiency. Of course, the ECL power supply is nowhere near the whole story. The following additional power supplies are in the system: quant model output use ----- ----- ------ -------------- 1 H720 +5, -15 DECtape system 1 H725 1 H7420 AC power supply PDP-11/40 3 H744 +5 1 H745 -15 1 H754 +20, -5 1 H732 0-20VDC margin check 1 783-C +10, -15 1 H7420 AC power supply 1 H744 +5V CPU cage TTL supply 2 H744 +5V I/O cage DTE20 TTL supply 1 H744 +5V I/O cage RH20 TTL supply 1 H7420 AC power supply 4 H744 +5V I/O cage RH20 TTL supply 1 H7420 AC power supply 1 H770 +15V air flow sensors 1 H745 -15V I/O cage DIA20/DMA20 3 H744 +5 I/O cage DIA20/DMA20 TTL supply I have not found any figures for typical current used by the various subsystems. However, the ratings of the regulators are: H720 5V 22A, -15V 10A, unregulated -22V 1A, unregulated +8V 1.5A (unregulated outputs not used in KL10) H732 0-20V 5A H744 5V 25A H745 -15V 10A H754 +20V 8A and -5V 1A H770 +15V 10A DEC didn't waste any more money on regulators than necessary, so it is a safe assumption that a fully configured system will use most of the available DC power, which for just the +5V supplies alone is 1860W. Fortunately the power supplies used with the H7420s are switchers, so they are probably at least 65% efficient. Eric

ESDI Cabling

The only PC ESDI controllers I have ever found all have 2 data cable connectors (20 pin on the card), which can each connect to one drive only, same as MFM. In fact right now I can't think of any differences between ESDI and MFM cabling for PC's. Not sure about the twist details though.

IBM 1130

by rigdonj＠intellistar.net

I contacted a friend of mine that that is a salesman for IBM and asked him if he knew where any IBM 1130s might be found. Here's his reply: > >Joe, >Sorry it took so long to reply....I was in Vegas and didn't get back until >yesterday. It was the annual World Gaming Congress meeting...the largest >gaming convention in the industry. > >Well...I got to admint....I've never even heard of an 1130!!

WANG WLTC up for trade

by roblwill＠usaor.net

Hello everybody. I have a WANG WLTC laptop computer (circa 1980's). I do not want to sell it for cash, but I'd be willing to trade it for another unusual portable/laptop. Here's some specs on it: -NEC V30 (8086) processor -10MB Winchester Disk -External Centronics-type SCSI port (HD is also SCSI) -Built-in thermal printer, with roll/cut sheet capabilities -512K RAM -RS232-C Serial port If you're interested in it, email me, and I can send you more info and/or a picture of it. There is, however, a problem with the internal (regulating/switching) power supply. It runs the computer, but keeps blowing a capacitor. It also needs an external P/S and battery. The battery is 10 sub-cells (with a resistor - I have a schematic). A Tyco 20VDC racing transformer (the kind for the little car/track sets) will run it. I had an offer to trade it for an IBM PC-Radio, but I never got a reply. If anyone has one of these, or any other odd or unusual laptops/portables, and would be willing to trade, let me know. ThAnX, -- -Jason (roblwill(a)usaor.net) ICQ#-1730318

ESDI cables for PC's may or may not have a twist. The drive has a jumper (usually marked drive 1 or 2) that must be set accordingly. I've had a lot of trouble getting old ESDI drives to work also, especially with Western Digital controllers. I thought all my drives were bad until I found a Future Domain controller that worked with most of them. The drives also need to be low level formatted by the card being used. Hans Olminkhof

Nicolet, DEC rescue coming up

by jfoust＠threedee.com

A few months ago, I picked up a scavenged non-working MicroVAX and a little VaxStation 2000/VS410 from a junk storeroom at Nicolet Instruments in Madison, WI. I'd missed a pair of much nicer graphics-equipped MicroVAXes dumpstered a month or so before. I've received word that they're clearing out this storeroom. I know there'a a TK50, carts, manuals and lots of other misc. junk, including several Cypher (?) mag tape units. It was piled high and deep and very poorly organized. There's also a rack-mount Nicolet 1280 that was known-working when retired. Mr. Ismail, you have a 1080, would you like another from the Nicolet family? I'll pick up what makes sense, and post a list. I doubt I'll want to keep it all. - John

Vaxstation 3100

by pechter＠shell.monmouth.com

I just came out ahead on a Vaxstation 3100 from E-Bay, having skipped the MicroVax3300... Looks like it's a 3100 Model 38... can someone point me to video pinouts, monitor specs etc since it's coming CPU box only. I'm wondering if it will drive any of the Sun Sparcstation monitors without a problem (or a modern multisync). At worst I'll run it with a VT100 (or 320 if I can find an MMJ cable). As soon as it arrives I plan to load it with VAX/VMS from the non-commercial hobby distribution... I'm wondering if I should check to see if there are any licenses and software on the box first. Any suggestions? Can this machine boot off a second drive -- I'd like to put NetBSD up on an external drive. Any pointers to FAQs and info on this machine would be appreciated. I left DEC after the MicroVax II and 8650 so I have no info on this machine. Boy, will it be good to see VAX/VMS again. Bill Bill

More Swapmeet stuff

by jpl15＠netcom.com

Along with the Compaq books and the Jonos Escort previously described, I just stumbled (literally!) over the other bit of vintage digital gear.. an unopened/shrink wrapped box containing an AT&T Voicepower VP1 module for the 6300 series. The box is marked "Work Group System Voice Power" I haven't opened it yet, but there was a stack of about 25 of them, 20 of which had been sold en masse. Apparently it is a trainable voice-input command module. Along with it (unrelated) was the AT&T version of the IBM user's guide for the 6300, with disks. Since I have two 6300s skulking around here, I can hook this thing up and see what happens... The VCF II sounds like it will do more than was thought to further the aim of Thechnology Preservation.... but that's why we do this, no? Cheers John
