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. I compiled Eric's utilities on an SGI running IRIX, with the IRIX C compiler, like this: cc -O -fullwarn -o tsbextract tsbextract.c tapeio.c cc -O -fullwarn -o tsbdecode tsbdecode.c tapeio.c ("-fullwarn" is the IRIX cc equivalent of gcc's "-Wall"). If you want to use tsbdecode (to list BASIC programs), ask Eric if you can have the updated version (tsbdecode is a work-in-progress, and I recently sent him an update which takes it a bit further towards its goal). -- Pete Peter Turnbull Network Manager University of York

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 I guess ELM is based on an out-of-date (not-quite-)standard (RFC1049), though even then that header is illegal according to RFC1049.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

by jwstephens＠msm.umr.edu

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. Harve Harve Thorn Greenmiddle School Greenland, AR 72701 hthorn(a)greenland.nwsc.k12.ar.us > From: Martin Scott Goldberg <wgungfu(a)csd.uwm.edu> > > Anyone have any extra old Corvus hard drives?

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. Don't buy a coin door from Happ. You can get them on eBay for about $30 + shipping. <snip> _________________________________________________________________ Cell phone ‘switch’ rules are taking effect — find out more here. http://special.msn.com/msnbc/consumeradvocate.armx

Space Invaders returning to arcades...

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. There is also the issue that you're not allowed to distribute ROM images with MAME, so you'd need some way of distributing the images separately. -- Pete Peter Turnbull Network Manager University of York

SGI 4D/35 Personal Iris question

by bdwheele＠indiana.edu

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. Or they may keep the drive selected for a while in case whatever software is asking for sectors, asks for another one. > > So Tony's idea could handle everything including an LLF, for any format > > and any encoding scheme you like. > > Which, IMHO, is important. 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 ;-)

It's an ordinary text file, compressed with gzip. However, it's not STD39 at all. It's not even related to it; it's RFC903, which is about RARP (Reverse Address Resolution Protocol). It looks like the people who run that FTP site have not only not updated it in ten years, they've accidentally copied their STD38 file as STD39. -- Pete Peter Turnbull Network Manager University of York

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

> 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

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
