Hi, gang, FYI: I'm in the process of converting a 1991 vintage Data I/O device wallchart to spreadsheet format. Once done, it will provide the family & pinout codes for just about every device Data I/O was supporting at that time. Said codes are necessary when using older programming equipment, such as the 19, 29, and 212 families. The file will be made available in Quattro Pro spreadsheet and .PDF formats, if all goes well, and will be stashed on my FTP site. I'll post an additional note when its ready. It's going to take at least a month or so, as there's a -ton- of raw data in the thing (I'm working on a little each day). It will be sorted by Manufacturer, Device part number, Package, and F/P code. No charge... I'm doing this because I know a lot of people have the old programmers, and I hate to see good equipment go idle simply because the manufacturer no longer supports it. Besides, this is something I'd love to see if I were still using a 29 or something similar.

Aztec C-86 3.40a command line args

by msg＠waste.org

Greetings: We're wrestling with Aztec C-86 3.40a for MS-DOS (1986) and have no docs; we'd very much appreciate a description of command line args and switches for the various tools (if anyone can still find this info), especially the linker 'ln.exe'. We've compiled objects and libraries for a version of KA9Q specifically modified for a newer version of Aztec C (we needed to remove function prototypes and do other workarounds) but the linker chokes on backward references to unresolved symbols. Reordering the objects in libraries is not feasable as a workaround since that would create another set of backward references. There must be a way to get the linker to work properly on its two passes... All replies much appreciated. Michael Grigoni Cybertheque Museum (msg _at_ cybertheque _dot_ org)

Reel-to-Reel care?

by aek＠spies.com

I think as long as the cast is made from an existing roller then a bunch of them can be turned out in a short period of time. --- Wax casts are for one-shot use. That's why they're wax.. Fancier casts would need to be two-piece so you can get the part out. But, a two-piece would leave a seam. d

Hopefully not a silly question

by scschaut＠peoplepc.com

Hello Jonathan, I was doing some extensive surfing regarding SEMs, and I happened upon a message that you posted regarding an ISI-WB-6 SEM/EDX that you were giving away, as it was taking up space in the hallway. Of course, the message was posted March 9 of this year (my birthday, but that would be true for approximately 1/356.25 of the earth's population). But I just have to ask: Is that SEM still blocking your hallway, or did somebody mercifully relieve you of it? If not, and you still would like it to find a new home, I would find that a most tantalizing prospect (I wonder how much an interstate transport permit would be for an X-ray source to haul it to...California). I hope that the weather isn't too miserable in Ohio these days (I used to live in Wisconsin, so I know), and have a great weekend! Take care, Steve Schaut

22-pin PCMCIA cable

by rmeenaks＠olf.com

Hi, I am looking for a 22-pin PCMCIA cable for my Sundance/Applied Transputer Technology PCMCIA transputer card. The current cable that it comes with is not compatible with the transputer boards I currently own. Here is a picture of the card itself: http://www.classiccmp.org/transputer/smt104.htm The cable needs to connect to the card itself. I need at least 17 wires >from the 22 coming from the cable. Here is a picture of the PCMCIA side of the cable: http://www.thesupplynet.com/productDetail.cfm?prodID=453 I have this, but the problem is it only has 8 wires and I cant seem to open the shell. Any help is much appreciated... Cheers, Ram PS: This is a B004-compatible transputer interface that I am planning on running on an Ultra 2 Enterprise Sun workstation with the Sbus-based PCMCIA card :-)

LGP-21 (and LGP-30) software

by Christian.Corti＠studserv.uni-stuttgart.de

The site is indeed very interesting. In our computer museum at the University of Stuttgart we have a complete working LGP-30 with Flexowriter and high-speed reader/punch since 1999; it is probably the only working machine on earth. I met David Weil of the Computer Museum of America last year and I gave him a copy of the german maintenance manual including schematics of the LGP-30 and all our paper tapes (read in on a PDP8/e and transferred to a PC with Kermit) on a floppy disk. In return I copied the essential parts of the american LGP-21 maintenance manual (not the complete manual because of the excessive high costs of $0.10 per side) and extracted the wiring diagram of the little daughter board which is in my eyes an instruction set modification. There were many such modifications/enhancements for the LGP-21 for which we have all the documentation and blueprints and I know of a modification for the LGP-30 which added a -Z instruction and an overflow flag in the program counter. I have reengineered this and added it to one of our two LGP-30 logic boards. It is working but we have no software which makes use of this new feature. We have the original and complete sets of schematic diagrams, blueprints and software for the LGP-30 and LGP-21 (except SW). For those who are interested the LGP-30 papertapes can be found at ftp://ftp.informatik.uni-stuttgart.de/pub/cm/lgp30/papertapes and some pictures and (german) description (needs to be updated) at http://computermuseum.informatik.uni-stuttgart.de The paper tapes include the Act V compiler, basic subroutines, 10.4 (successor of 10.0) and 9.0 (bootstrap loader), as well as the original Blackjack game (yes, it's there!) and other stuff. All tapes have been converted to ASCII but there are tools to convert from ASCII to FlexCode and vice versa. I have also written a LGP-30 simulator for MS-DOS (written in Turbo Pascal) that runs all LGP-30 software. I have not published it yet because I have to cleanup the code and translate the messages into English. I will put it onto the ftp server if this is done. I would be very happy for any comments and discussions on the LGP-30 or LGP-21, especially if there is another *working* LGP-30 out there. Our one was built in 1958 and it's working perfectly, the drum has no "bad sector"! Christian PS: Here's a transscript of my simulator running Blackjack. The output is in color (black and red) and it appears to be the same program as the one on Tom's site. *** LGP-30 Simulator *** HALT (C) 2000-01 Christian Corti 5 - c 7 - s 4 - s Card? yes 9 - s Card?

New finds, RFI

by pat＠computer-refuge.org

I managed to finally open up and look at the Westinghouse/Unimation roboto controller that's been sitting out at Purdue Salvage for the last few weeks, next to a robotic arm that probably weighs >1000lbs and has been stripped of some of its parts. To my suprise, I saw a bunch of what looked like QBUS boards in it... pulled one out and said 'this looks like an 11/23 CPU board. cool!' After getting it home, and seeing exactly what board it was, I discovered it was an M8192-YB... an LSI-11/73 CPU. Along with that was a 64kW SRAM board, a pair of DLV11-J 'clone' boards, and some robot controller hardware... This is a nice topping for the past week... so far in addition to this I've managed to get (for next to nothing): - A pair of Texas Instruments Business-Pro machines - 286-based DOS/ XENIX machines that looked complete (minus kb, monitor, cables) - A SPARC IPX and a few Type 4 keyboards - (OT) A Sun SparcServer 1000 with 3 boards and 5 cpus in it. - (OT) An HP C200 workstation with a high-end 3d accelerated video card - (OT) An IBM C20 workstation, maxed out with RAM Now the real question: Does anyone know anything about the TI Business-Pro machines? Specifically, what kind of monitor and keyboard do I need for it? The keyboard connector is an 8-pin DIN, and I don't see anything that looks especially like a video connector on it. Or can I use a serial terminal with it? I'm doubting it since it's a DOS machine, but not ruled it out yet...

OT: Email header question

by julesrichardsonuk＠yahoo.co.uk

Hi all, In light of the recent thread about email headers, somebody may be able to help with this one. I don't normally have any problems with the emails that I send out; however one particular person who I send mail to complains that anything I send to him appears in a much larger (unbearably so) font than mail that he receives from anyone else. Maybe someone can have a look at the header on this message and see if there's anything obviously missing (it looks fine to me) FYI, a reply from him showed the following info about his client: X-Mailer: Microsoft Outlook Express 5.50.4522.1200 X-MimeOLE: Produced By Microsoft MimeOLE V5.50.4522.1200 I suspect I send email to a good many people using the same client / version, so there's nothing odd about that. I'm using Evolution as a client on a linux box, with sendmail doing the address munging so that my reply address appears correctly, so that's a little atypical but not *that* odd. Anyone shed any light on what's going on? I would have said it was a problem with his client, if he'd been getting the same font problem elsewhere, but it seems like his version of Outlook doesn't like mail sent by Evolution for some reason... cheers Jules

DEC stuff available (old, but probably not old enough)

by jack.rubin＠ameritech.net

I have the following: - 3 Personal DECstation 5000/25 (1 w/ 2.88 floppy) + manuals - 1 keyboard and mouse for the above - 3 DEC Storage Expansion units (2 with CD, BA46A, 1 without, BA42A); each has a 95MB CompacTape unit - ULTRIX v4.2 on CD, plus DEC Fortran for ULTRIX, v3.2 - 1 DECpc Lpv+ 405d2 1 DELNI 8 port hub Used to work, no idea about present state of operation or completeness. No monitors or other keyboards, mice or cables. DECstations have gooey feet. Located in Evanston, IL - northern suburb of Chicago. I'm interested in H8-H/Z89 stuff, Godbout/CompuPro docs, 8-bit single board computers, if you feel like trading something, but mostly I want to keep this stuff from the crusher, which is where it will go otherwise, come January. Best is if you come pick it all up, second best if you come pick some of it up. If I have to ship things, you will need to pay postage + a few bucks for packing materials and entropy reversal. FIFO distribution process, though local pickup trumps shipping. Jack

Databook Thincard

by aw288＠osfn.org

I suppose I have one of these things, and really want to make it go away. This is apparently a late 1980s precursor of the PCMCIA card - about the same size, but the connections are different. Anyway, this little "drive" (officially a TCD/1-E from Databook) is mounted in a cradle, so it fits into a 5 1/4 half height bay. I have no idea what the interface is. Tagged "Not for Life Support or Nuclear Use". So, anyone want this thing for a buck and postage? William Donzelli aw288(a)osfn.org

FAT file system now licensed by MS ?

I appreciate any ideas on this one. Bob, I used an Apple serial card, a null modem cable, and a simple BASIC program to use the serial port. There have been some Apple emulators. Does anyone know if any of them can read Apple 5.25" floppies? I know that in the evolution of 5.25" drives and densities, there was the issue of wide heads, wide write tracks, and later heads and tracks were narrower. Was it that modern heads could read earlier tracks? Greg

Building a PDP-11 for the first time

by chrisc＠addpower.com

The M8190 was salvaged from a PDP-11/23 backplane where it had been running, so I assumed that it would work in a QBUS setup. Is there an easy way to tell whether the card is really Unibus or QBUS? > > M8190-AB (11/84 cpu) > > I separated the '84 CPU because it's oops Unibus and not > Qbus. Everything else you have listed is Qbus. The busses > don't mix. Actually a PDP-11/84 uses a Q-Bus CPU in an adapter of some sort, same with the memory. My concerns with what I see listed above are if the memory will work with the CPU (did it come out of the same system?), I don't have time to check the part number. The other concern is, since you're wanting to run 2.11BSD, is the disk controller supported?

The thing to consider is that we are not sampling a "square" wave. It is a variable pulse width digital signal. The only kind of processors I know of that could handle this from a port is some of the latest DSP chips. Using a PC, even one like our ( AMD ) latest Opteron wouldn't do well since it is so highly pipelined and unpredictable in execution speed at this short a time interval. There are a number of DSP evaluation boards out there that places like ADI and TI sell that could be made to handle this task. Of course, a simple pulse width counter on the front end could simplify the sampling process. > >

Free Stuff

by tponsford＠theriver.com

Hi All, Got a whole pallet load of old documentation for $2 at the local University Auction. Some Stuff I'm keeping but if anybody is interested in some of the other stuff, its your's for the cost of shipping, probably USPS media mail, or UPS at your choice. Free to good home: Evans and Sutherland PS 390 Documentation Set (circa 1987) 4 Full size Binders including Hardware and Software documentation. OSF/1 manuals all topics about 40 or 50 manuals all together. I'll keep a few, but the rest go. Digital Unix manuals, about a dozen, all topics. most are the usual software documentation. Digital VMS 6.2 manuals almost a complete set. These are not the big "grey wall" of dec binders but the newer paperback manuals. All of the manuals are in Great condition. It looks as some have never been used. I will have a list of the OSF/1, DEC Unix and VMS manuals in the next few days,(as I go through them) but if your looking for a special one, contact me off-list. Remember as I'm doing this for free (ie cost of shipping) it might be a while before I get them sent. Also, the last time I did this, I got burnt by some on this list who never sent me the shipping costs, so this time shipping costs up front. Thanks Tom Ponsford

SGI 4D/25 Personal Iris keyboard and mouse

by julesrichardsonuk＠yahoo.co.uk

Hi all, Any ides if the keyboard and mouse needed for an SGI 4D/25 was used on any of SGI's other models? A machine just cropped up for free but it's got no mouse or keyboard with it. The keyboard socket on the machine is a 9-pin D-type female (umm a B-type in correct terminology I think) - I'm assuming the mouse plugs into a port on the keyboard, rather than tying up one of the serial ports on the machine? Oh, the root password isn't known either... but I'm assuming there will be ways around it on a machine this old. cheers Jules

DEC VT420 terminals on VCM

by vcf＠siconic.com

I just listed 8 DEC VT420 terminals on the Vintage Computer Marketplace. I'm asking a mere $5 each plus shipping. They are in anywhere from good to excellent condition. Some have slight burn in. They will be sold off in the order of best to worst, first come first served. Items #300, 302-308. I also listed another Sharp PC-5000 (new in the box). See item #301.

PDP 11/84 systems available

by hilpert＠cs.ubc.ca

A friend who manages some communications systems expects to be decommissioning 3 or 4 PDP 11/84 systems soon (~ end of 2003). These systems have been functioning for approaching-two-decades in a (presumably) good environment. Sorry to be a little vague on details (I'm recalling this from a quick verbal discussion) but each system is something like: PDP 11/84 CPU RL02 removable-platter disc drive MD17 / MD175 fixed disc (?) tape drive (9-track I believe, but that seems a little odd, like it would more likely be those mid-80s DEC cartridges) other I/O interfaces presumably I don't know what OS they were running/installed with. Email me and I'll try to get clarifications if desired. I know these aren't the most desirable units of the PDP 11 family (too young and no blinkenlights) (poor not-so-little things), but any takers for adoption? Any bits or modules to be rescued for someone? Location is Vancouver, B.C., Canada. Price is take-it-away-it's-yours (unless we can twist your arm into making a donation to the radio museum with which we are associated). (Smaller bits I will consider doing for the price of shipping.) -------------------- http://www.cs.ubc.ca/~hilpert/eec

Maybe they're just trying to get rid of the thousands of junk tapes they have around. Anyway, I end up with a closet full of tapes every year. Kelly

Disk hardware emulation, was Re: Grandfather system RTE6/VM?

by aek＠spies.com

Something else that would be nice to be able to do with this sort of hardware would be the ability to read an arbitrarily formatted real disc drive. The MFM drives in Xerox 6085's and 8010's have 'interesting' sector formats that can't be read with normal controllers.

USB 5.25 floppy

by cb＠mythtech.net

>I'm sure one can be built, but I've seen drives like these before (but for >the Macintosh). I just saw a 3.5" USB drive this morning connected to a Dell. From the looks of it, that is they way Dell was delivering the drive for that computer (it was a tiny little tower like unit and had no floppy built in). So they are available for more than just the Mac. I think the one I bought for my father's iMac (so he can transfer pics from his Mavica camera) was not Mac specific and was supported by Windows and Linux according to the box (but the drive sucks, its PAINFULLY slow to copy data, far slower than the USB bus so the speed isn't killed by that... IIRC, its a "SanDisk" brand drive, but I could be wrong). -chris <http://www.mythtech.net>

One of the reasons for starting the bitsavers archive was to try to collect descriptions of various peripheral interfaces.

HP-85 Rom Emulator

by bkotaska＠charter.net

I'm working on a ROM emulator for the HP-85 - i.e. a replica of the original (and hard to find) Programmable ROM Module. From photos (thanks to Vassilis Prevelakis), I've drawn a schematic of most of the original module. But I've hit a snag where some of the traces disappear under the ICs. I've been able to deduce most of these but some are too ambiguous to "pin" down. Is there someone who owns this elusive module that would be willing to ring some paths for me (probably 10 to 20) ? Some connections may be obvious simply with a closer visual inspection of the actual module. Thanks, Bill

HP2000 and old archive stuff NOT on 9-track (apple2 transfer??)??

by pete＠dunnington.u-net.com

Kermit, probably, unless you already have a terminal program with file transfer capability on the Apple. You can get versions for just about anything, at http://kermit.columbia.edu/kermit/howtoget.html or mirror sites. Kermit can transfer binary files without loss or corruption between all sorts of systems. The tricky part is getting file transfer software onto the Apple in the first place. Kermit-65 (for the Apple ][) is available as a hex file which you can transfer fairly easily and convert to a working program; after that, the rest is easy. Look for the files that start "app..." for Kermit-65 for the Apple. ftp://kermit.columbia.edu/kermit/a/appaaa.hlp will tell you what they all are, and get you started. It's easier for the PC, all you need to do is download the relevant program (I'd suggest the slightly older DOS version, which is free, and works under Windows as well, despite the disclaimer -- or at least, it does for me). -- Pete Peter Turnbull Network Manager University of York

Early 80's formulas (esp. Memorex) will (has..) become unusable. I've personally had much less problems with 3M formulations. The long term prospects of tape transports with any rubber parts is not good, either.

My understanding is that the selected compensation is only used for the write. The read amps do have some non-linear response to compensate for the normal effects of megnetic data. From what I've seen, the read is fixed for and compensation so regardless of the track, one should be able to provide data with the same framing as any other track. Dwight

Reel-to-Reel care?

by ken＠fraserhouse.com

Greetings, Does anyone have some "care and feeding" tips for vintage reel-to-reel tape drives? I've recently purchased a couple nice 9 Track drives, and want to make sure they (and the media) last as long as possible. I've already given the heads, rollers and guides a good cleaning with 99.9% anhydrous Isopropyl Alcohol using 'fuzzless' cotton cleaning sticks, and plan to do so on a regular basis. Is there such a thing as too much cleaning? ;) What other tips and tricks should I know? For example, should I always unload and store the tapes in their carriers immediately after I'm done using the drives, or can I safely leave them loaded for an extended period (oxidization? de/magnetization? deterioration?). They definitively look cooler with tapes loaded :) Thanks, Ken C.

Is the drive a listed size drive 170, 380 or 760 meg ?? The "System boot" is the code that gets you from the Rom monitor to the System OS. You should be able to enter "ld" at the monitor prompt and the system will list the machine dependent boot files (not system boot). The "system boot" is installed when the drive is involed. It is also checked when the OS is loaded. That's why you get the message that it was found and is being skipped. If the monitor can't find any system files do a "di w" and try again. I still have a Apollo ring here with a working AA install area. if you get in a jam contact me by email. The tapes are not reliable in age and can have fatal errors if used a lot.

If you want to use the Makefile you need gmake (GNU make) not an ordinary make, and gcc, because the rule that creates the .d files from .c files uses gcc-specific switches. I didn't bother.

bbc master 128 plus 512 board + 2 disk drives

by constable＠powerup.com.au

Hello Tony I am interested in selling a Master 128 computer. I was referred to your site by a friend in computing. I thought that I might boot it up again, and with the use of its RS232 port I would use it as a controller for a variety of electronic projects (such as are sold at Tandy's or in Australia Dick Smith Electronics's). But I have become more interested in traditional photography. It is a BBC master 128 computer. And I have a circuit board to upgrade it to a 512. I have the 2 manuals that go with it, each is nearly an inch thick, and I have the manual from the computer it was derived from, the BBC B, again nearly an inch thick. The earlier manual heavily complements the Master 128 manuals; it is a great shame it wasn't sold with them. It would have saved me some grief. I also have a workshop manual for it including wiring diagrams and diagnostics. I have two single 5 and a quarter inch disk drives plus a heap of original discs and software. I have a stack of computer magazines, over 2 feet tall, which include programs and electronics projects for interfacing all sorts of devices with it. I used to use my colour tv as my monitor and an Epson FX 80 dot matrix as my printer. Regards David Constable

True, it should contain a subtype. On the other hand, the header is only required if the mail uses MIME (Multipurpose Internet Mail Extensions). RFC2045 allows *extensions* -- but does not require them. RFC822 is authoritative for plain-text messages, and that header simply shouldn't be there at all. It shouldn't appear without the rest of the MIME stuff, anyway. I guess ELM is based on an out-of-date (not-quite-)standard (RFC1049), though even then that header is illegal according to RFC1049. Not, however, an excuse for some broken software to consider plain text to be a virus. -- Pete Peter Turnbull Network Manager University of York

Don't believe everything you see in a mailing list archive :-) Something to do with the archive (and maybe the digest? Are you guys getting the list (it's a mailing list, not a group) in digest form?) is misunderstanding something -- and apparently so is your Outlook Express, if it tells you that Tony's messages are anything other than normal ASCII email. Tony's using ELM, a perfectly respected mailer. There's *no* attachment at all in Tony's messages, and if there were, the mailing list would strip it off. What you're seeing are messages without a MIME type, and something is trying to make them fit an inappropriate mould. They don't appear on the list with any attachment when I receive them, and messages I've had from Tony directly certainly are not like that. They have headers like this: From: ard(a)p850ug1.demon.co.uk (Tony Duell) To: cctalk(a)classiccmp.org Date: Tue, 9 Dec 2003 03:04:53 +0000 (GMT) In-Reply-To: <1070934186.3030.321.camel(a)dhcp166-138.ace.uci.edu> from "Tom Jennings" at Dec 8, 3 05:43:06 pm X-Mailer: ELM [version 2.4 PL24 PGP2] Content-Type: text Subject: Re: Disk hardware emulation, was Re: Grandfather system RTE6/VM? not like this: > Message: 2 > Date: Fri, 5 Dec 2003 23:46:39 +0000 (GMT) > From: ard(a)p850ug1.demon.co.uk (Tony Duell) > Subject: Re: Disk hardware emulation, was Re: Grandfather system > RTE6/VM? > To: cctalk(a)classiccmp.org > Message-ID: <m1ASPek-000J2AC@p850ug1> > Content-Type: text/plain; charset="us-ascii" > > A non-text attachment was scrubbed... > Name: not available > Type: text > Size: 2441 bytes > Desc: not available > Url : > http://www.classiccmp.org/pipermail/cctalk/attachments/20031205/10cc7c9a/at… Moreover, they have no attachments, no hooks for attachments, and nothing other than correct ASCII headers and plain ASCII text (as, indeed, the headers indicate).

5 1/4" disk drives, 1/4" tape drives and media

A friend is shutting down a business and has a quantity of hardware available. His schedule for getting rid of this is by 12/31/2003, so do not respond to this after that time (like in 7/2004 at least) as he will probably be successful in getting rid of stuff. modems, disk drives, tape drives, all sorts of cards. the disk drives are up to 1gb and may be of use in older minis as well as older PC's. The tape drives are the same. He also has a large amount of printer supplies and documentation available (Al K?) Please email: harold(a)crsinc-pa.com or call: 215 674 1399 CRS incorporated. ask for harold, he can tell you what he has and what he wants for it. If you are in the eastern pennsylvania area, you might go get larger amounts. Thanks Jim

WDC1797 floppy controller data sheet?

by swtpc6800＠comcast.net

I found that it helps to search for WD179x or WD279x when looking for Western Digital FDC data sheets. A good set of WD179x (and WD1771) data sheets and appnotes can be found on David Keil TRS-80 page. http://discover-net.net/~dmkeil/trspdf.htm On the tool bar on the left side go down to the "TRS-80 Books & Technical Manuals" icon. A copy of the 279x data sheeets can be found on my site. http://www.swtpc.com/mholley/DC_5/TMS279X_DataSheet.pdf Michael Holley

It > could be just sampled at the speed of the drive. I'm sure Tony will comment further, but his idea has the merit of not being restricted to single sectors; in fact it doesn't need to know *anything* about the data it's handling. It can start sampling when the interface is set to write and the relevant drive is selected, and stop when it isn't. Similarly it can replay the data stream when requested. There's nothing magical about a sector, it's just a stream of interspersed data and clock bits -- headers and all. However, it does need to be oversampled so you can get the timing right. An ST506 interface is very similar to a floppy interface, only 10 or 12 times faster. The way you read a sector from an ST506 interface is to "listen" to the data strema until you see the header for the sector you want, then start capturing the data. The way you write is to listen, and when you see the end of the preceeding sector, you wait (for the inter-sector gap time) then turn on the write signal and write a sync pattern, a header, more sync, the data+checksum, then turn the write signal off. Actually, IIRC you only rewrite the data, unless you're doing a low-level format. So Tony's idea could handle everything including an LLF, for any format and any encoding scheme you like. > c) Something that works "with most ST506 drives" is, IMHO, not good > enough.

You'll have a job to get a parallel port or any other standard interface to work fast enough to talk to the ST506 side. On the storage side, you could use anything you like -- make the software in the emulation system modular, and storage is just storage -- whether it's SCSI, ATA/IDE, network filestore, flash, whatever. -- Pete Peter Turnbull Network Manager University of York

apple/corvus hard drive

by maya2blue＠juno.com

Hi Al, I have just joined the list and noticed the April 2003 exchange between you and Martin Scott Goldberg re Apples and Corvus hard drives. That subject is why I joined the list! I have been searching for documentation and admin/maintanence software for the Corvus hd for sometime. I am a middle school teacher and have an old IIe/Corvus Appletalk network that my kiddos use. It was orginally part of an Impac Learning System lab. I "snagged" it when we upgraded some years ago. I have ten computers, a hd chock full of MECC software and a variety of other software. I also have a 4 drawer file cabinet full of Apple software, and lots of extra apple talk cards/cables/etc. What I want to do is learn how to "add" or "delete" pgms from the HD in order to use more/different software. The specifics of the HD are: Corvus model 74MB7 Rev C SN 398-GN9230-P I have no hd software or instructions of any sort. I *do* know how to connect it all, boot it up and use it. :) Just wondering if anything you have in the way of docs or software might be of help to me? Or perhaps, you could point me in the right direction! Please let me know if you can be of help, and what sort of costs might be involved. Many tks your help.. Best regards.

Not 100% sure that they are still working, as they have been in storage for over 10 years. I also have controller cards and manuals/software for them. I'd love to adopt them out to a good home, and wouldn't want much for them. I just can't stand to throw classic computer stuff out, but would love to lighten the load around here... They are heavy and shipping would be expensive. It would probably cost more to ship the units than I'd want for them... Contact me off list if you're interested...

HP Apollo DN5500 disk and sysboot

by arohirohi＠hotmail.com

I am trying to salvage a nice Apollo DN5500 server. Unfortunately I had to swap the original Maxtor ESDI 760 HD - it makes a clunky noise - for a lower capacity Micropolis and I have some difficulties to reinstall DomainOS software. The system starts under service mode. It can read a bootable tape and install the mini DomainOS software but it cannot boot DomainOS directly from the hard disk ... it dies with an "Error: sysboot not found" What I've done ... in service mode, with a 10.3.4 boot tape inserted, > re > di c > ex config, ex calendar, ex invol ... to enter the new hd configuration, setup date/time and format hd then ... > ex domain_os ... does a lot of shoeshinning, copy base OS from tape to hd and says that sysboot is found and skipped ... ) go ... goes to HP logo and login or ) sh runs a text shell ... I was delighted ... but now if I shutdown and reboot the system in normal mode, it passes the tests ok but fails to start the base OS complaining about "sysboot not found". Same result in service mode if I do a > re and > ex domain_os. Considering that it boots fine from a tape, I assume that the sysboot is not a eprom program and that it has been erased by formatting the drive. Does anybody know how to install the sysboot. Does it have anything to do with the 40KB file copied from the tape to //nodeXXX/sysboot on the hard disk? Kind regards, Aro

Space Invaders returning to arcades...

by r_a_feldman＠hotmail.com

I've been buying from Happ Controls for almost 15 years to make interfaces for museum interactives. Their products will stand up to severe pounding. I've been using the same trackball with my regular PC for 12 years and I've only had to clean and oil it once. When I took it apart to oil the bearings, it looked like one of the rollers had worn a bit, so I wrapped a piece of Scotch Magic Tape (R) around the shaft, and it has been working fine for the last two years. Bob Date: Sat, 06 Dec 2003 21:59:36 -0500 From: "Richard A. Cini" <rcini(a)optonline.net> Subject: RE: Space Invaders returning to arcades... I don't recall this being mentioned before, but I've found that Happ Controls (http://www.happcontrols.com) has everything you need to build a proper MAME setup. The buttons are reasonably priced. The trackball will give you a bit of heartburn. The spinner is a must-have.

A few of them, perhaps, but I suspect a lot of copyright holders might get upset about that. If you're thinking about the exemption granted for obsolete games, it only applies where "machine or system necessary to render perceptible a work stored in that format is no longer manufactured or is no longer reasonably available in the commercial marketplace." If someone manufactures and sells machines, especially for use in arcades, the exemption does not apply. It probably doesn't apply in Europe anyway -- it's an exemption to the United States Digital Millennium Copyright Act.

SGI 4D/35 Personal Iris question

Seeing the 4D/25 question, reminded me of a machine I've got in storage. I've got a 4D/35 with the storage tower thingy. Unfortunately, I only get the fault light when it comes up. After digging around in it, I found that the internal fan was shot. Would that cause the fault? I know they're heat senstive, so I suppose its possible the whole thing is hosed, but if its just a fan sensor, how would I determine that? Any hints on where to start? Thanks!

Most systms, if they want to read a sector, assert the select, wait for the correct header to come around, and then de-select as soon as they've got it. A lot don't of course; they wait until they've verified the checksum, and if it fails, they expect to see the same sector come around again.

No, it's essential if emulation is going to work for anything other than the simplest case of a PC with an ST506 controller (which is trivial to replace with IDE anyway). :-) BTW, it occured to me that you can alleviate the transfer rate problem on the real drive by splitting the data stream, like RAID systems do. -- Pete Peter Turnbull Network Manager University of York

FAT file system now licensed by MS ?

by waltje＠pdp11.nl

Hi, To my own laughter and surprise, Microsoft now claims to have the rights to the FAT file system, and intends to execute on a licensing program for it, with obvious results. Wasnt FAT done (in crude format) by MP/M or CP/M86 already *before* Microsoft? They claim it was developed by them in 1976, but I seem to recall it being mentioned before that, around 1974-ish or so, by homebrew people (such as CP/M et al.) ?? --f (who runs FAT on his own PDP-11 OS ;-)

Virus Distribution via this group

by r.mueller＠fz-juelich.de

Does anybody else have trouble with routinely receiving a virus in place of the proper collection of messages which constitute an issue from this group? What I often receive looks like ------------------ Virus Warning Message (IIIIIIIIIIIIII) Security warning Exceed_Decompression_Layer in file email-body The file email-body is moved to /etc/iscan/virus/virNUv9Rs. Information from IIIIIIIII Mail-Server: Scanner detected a virus (Exceed_Decompression_Layer) in an attachment (email-body) of this message. The attachment was removed from the message. No further action is required on your part. If you have questions, please contact postmast@IIIIIIIIIIIIIIIIIIIIIIIIIIIIII --------------------------------------------------------- ------------------ Virus Warning Message (IIIIIIIIIIIIIIIIIIII) email-body is removed from here because it contains a virus. I have removed the name of our mail processor and substituted several letters= "I". These viruses come numbered in the correct sequence, as if they were issued by the normal server which distributes the proper message collections. By the time the messages reach me any real content has been removed. Several of these arrive per week. One question I must face is whether our firewall is discovering non-existent viruses, and request a repair, but if the viruses are real, then the server for this group needs cleaning. It is possible there is somebody out there at a third point doing this, but how does this explain having the messages in the correct sequence and delivered to me while eliminating the correct message? (It never shows up, and how would this "Third Party Server" be trapping the proper messages in order to substitute a virus loaded message? If I were receiving one proper message and also the contaminated version it would be easier to explain.) Any advice would be appreciated. Bob

DSI NC2400 Reader Schem's?

by ohh＠drizzle.com

Hey, all: I've got a DSI NC-2400 paper tape reader/punch which is _almost_ completely working, but still has a small grumpy problem with its reader light source. Whatever it is, it's not as obvious as such a trivial problem _ought_ to be. :) Does anybody out there have a set of schematics or maintenance manual for the NC-2400? If it's scanned and available somewhere, great! If it's hard-copy, let me know and we can see what arrangements we can make. Thanks! -O.-

If they were making so much money that it was a overwelming gouge, other would compete against them. Arcade machines are not cheap to make. Doing 10K units of a 10 year lifetime is not a large run. The CPU board is most likely designed in house because they can not depend on outside vendors to keep an obsolete design. Any uP design is obsolete within 6 months to a year. They need a longer product life. Knowing the methods used to create these arcade machines, I would say that $3K is a little on the high side but not all that much. One wouldn't stay in business doing these for anything less then $2.5K. Maybe you know something I don't. Dwight

disc simulators

by aek＠spies.com

A good overview of disc formats can be found in two National app notes http://www.national.com/apnotes/Others__v17.html AN-413 AN-501 describes the SMD interface, but National doesn't have it on line any more. It can be found at: http://manuales.elo.utfsm.cl/datasheet/national/pdf/nsc04334.pdf There are lots of other related app notes there related to using their disc chipsets which would be handy as well

Byte Magazine article on IO Selectric interfacing

by brian＠quarterbyte.com

Hi, Does anyone have the June 1977 issue of Byte Magazine (vol 2 issue 6)? There are two articles in there that I'd like to get a scan or copy of: "Interfacing the IBM Selectric Keyboard Printer" and "A 6800 Selectric IO Printer Program". If anyone has this issue and can scan or copy and mail the articles, I'd really appreciate it. Contact me on- or off list. Thanks, Brian

Needing info on error messages for "option board"

by rich＠sias.us

I am trying to get Central Point software's Deluxe option board to work on reading and writing tracks on floppies. It has been 10 years since I wanted to do this. I have version 5.4 and the book only has a little info on errors. When TCM copies from the one track and "R" is for read then it is to qualify the track read, "Q", I can do this to hard disk. When I do this >from the temp copy on hard disk to another floppy it does not come back "Q" but "2" or once "3" and message box had message about destination directory. I think there was an error writing to floppy but I can't be sure. I tried all 4 port postitions for the 2 jumpers. Anyone out there still familliar with the "Deluxe Option Board" and all of its errors etc. I may have more questions. All the 'good' stuff I was looking for aparently is in archives of this discussion group that is presently unavailble. 1997-1999 era. Rich Sias

Copy of STD39 Internet Standard (BBN Report 1822)

by spedraja＠ono.com

> It is on my list of things to look for. > BBN 1822 describes the host to IMP protocol > > I'm hoping there is a copy in the SRI archives at the Computer > History Museum. Good luck. I only located something remotely similar to one copy, but in one unreadable format, in: ftp.univ-angers.fr/pub2/rfc/rfc/std/std39.txt.gz This file is 3.3k long, instead of the 187 bytes of the official STD39.txt The rest of documents involved in the creation of ARPANET are availables in more or less form in diverse websites. I made one recollection of links if someone is interested. My interest in all these items is diverse. Like a History Student with the focus put in Contemporary History. Same about an important lack of Classic Computing information in our country (Spain) even in Public, Private and Universitary libraries. And finally, with the intention to recreate a simulated Network of IMPs, beginning with the four first installed. It would be curious to see, for example, one PDP10 simulator running TOPS10, one Hercules simulator running OS360, and even one SDS simulator (software ?) with simulated IMPs attached. Don't you think so ? Thanks and Greetings Sergio

classiccmp server issue

by jwest＠classiccmp.org

Sometime around 3am this morning, the classiccmp server tossed cookies. Not sure exactly what happend, I tried powering it off and back on remotely - no joy. So, this afternoon (sorry, but I was busy gutting (refurbing) another HP 7906 drive and for once I decided my collection comes first!). I went down to the datacenter and hooked up a console. Got this wonderful message: "HDD S.M.A.R.T. monitoring has determined that a hard drive failure is imminent. Back up your data immediately. Press F1 to continue" *sigh* So I hit F1, made sure it came back up. All disks were present and accounted for. Tonight I'm sending copies of the filesystems over to a different server... just in case. Not sure how much I trust S.M.A.R.T., so I may let it ride for a while and just keep a closer eye on it. We'll see. On the bright side, my 2nd 7906 is now mechanically sound, servo/positioning tested ok too. On to the diags tomorrow for some read/write tests. What *IS* it with me and hard drives these days anyways? If it's not vintage ones, it's modern ones! Also I thought I'd try throwing this hook out - Does anyone have any 7906 drives that they are sure are junk and not worth keeping? If so, I would like to scavenge them for a spare set of cards from the card cage, the PMR board, and all the heads - especially the servo head. But only if it's pretty certain the drive isn't worth keeping and refurbing. Regards, Jay West

Hubs work fine, but only some switches. Any normal Layer-2 switch should pass Ethertalk packets.

HP2000 goodies tape conversion

by Chapmangregw＠aol.com

Hi, I have a backup and a hib tape for the HP2100A. I live in eastern Iowa, USA. (Iowa City to be very exact). Does anyone in reasonable driving distance have a reel tape drive that can read these old proprietary(?) tapes? (I'll start reasonable and then expand my begging circle :). (oh, and please do not hold aol against me, it is due to finances). Thankyou for your attention, Greg

I should agree too other providings > of Internet RFCs or STDs retired of the official list. You may have some trouble finding that, as it was one of the very few RFCs/STDs that wasn't ever online. You'd have to find a library that has an old copy, or find someone who has scanned a copy. Old RFCs aren't normally taken offline, so my "dump" of RFCs from around 1998 should be complete -- apart from ones that were never online in the first place, like RFC0007: 0007 Host-IMP interface. G. Deloche. May-01-1969. (Not online) (Status: UNKNOWN) which is a discussion about the software part for the interface This particular one *is* now online, with the following Editor's comment: [The original of RFC 7 was hand-written, and only partially illegible copies exist. RFC 7 was later typed int NLS by the Augmentation Research Center (ARC) at SRI. The following is the best reconstruction we could do.

DF32D

by ggs＠shiresoft.com

Does anyone have (scans are OK) of the maintenance docs for the DF32D. This is the posibus version of the DF32. On the same note, does anyone have the drive portion of a DF32 that they'd be willing to let go (or an entire DF/DS 32)? My DF32D is sans drive. Thanks. -- TTFN - Guy

100MFD 55V

by vrs＠msn.com

Hi, I've got an electrolytic I pulled from my TU56 drive because it had a big crusty electrolyte extrusion through the vent plug in the top. The capacitor is marked "SPRAGUE 100 MFD 55V - 60CY A5030". It is 2" in diameter and just over 4" tall, with two solder lugs on top. I think they are connected to the drive motors. I have looked for replacement electrolytic, but they all have way more capacitance or way more voltage rating, and are nowhere near the right physical dimensions. Is there a source for exact replacements? If not, should I just get one with the right diameter for the mounting clamp and the right capacitance, but some huge voltage rating, or is the voltage rating more important and I should beef up the capacitance instead? Or do I have to get both those right, and substitute a little dinky device? Thanks! Vince
