B.M.S. tape format

by ard＠p850ug1.demon.co.uk

This is on-topic if you think the HP9830 is a computer :-) I'v been thinking about the internal cassette tape drive of that machine, with particular refeerence to being able to read/write the tapes in some other machine. By chance I was looking at the technical manual for the Racal Thermionic (the company name, it doesn't use valves!) Digideck P72. This unit has obvious similarites to internal tape drive on the HP9830, in fact some mechanical parts will interchange between the 2 units. Anyway, it appears the data format is very similar too. There are 2 tracks on the tape. A pules on one track is a '0'. A pulse on the other track is a '1'. And a pules on both tracks together is a marker. The format of a byte on the taoe is M b b b b f b b b b M Where 'M' is a marker (and both markers are part of a given byte, by default, therefrore, there are 2 markers between the data bits of adjacent bytes on the tape), 'b' is a bit of the data byte and 'f' is a flag bit. The flag bit, being in the middle, appears in the same position in the serial-parallel conversion shift register no matter wheter the tape is moving forwards or backwards. I think HP used it to identify the bytes in the fiule header or something. It's not chear whether HP record 2 markers between each byte, or just one. But the Digideck can do either. Anyway, the Racal manual refers to this as 'B.M.S. format'. Has anyone heard of this? A google search doesn't find anyhting that looks relevant. -tony

ASR33 Partsbook and Facit 4070 manual

by ard＠p850ug1.demon.co.uk

>From time to time I get asked about the Teletype ASR33 Parts List (much harder to find than the other 2 volumes of the maintenance manual) and the service documentation for the Facit 4070 paper tape punch (which was used by just about all computer manuafacturers in the early 1970s...) I was poking around on www.hpmuseum.net and _both_ are on that site. The trick is that : HP2752A == ASR33 and HP2895A == Facit 4070 with HP modifications (an extra interface PCB, etc) In the fromer case the 3 volumes of the Teletype docs are available to download separately (the HP manual just gives the modifications to make it HP-compatible, and the schematics), tin the latter case there is one manual, most of which is the Facit service docs and parts lists. -tony

OT: How do I flash an ATI Rage 128 GL for a PC?

by woyciesjes＠sbcglobal.net

Apologies for being off-topic. Please reply to me directly, and not the list. I've got an ATI Rage 128 GL 16MB PCI video card from a B&W Mac G3. I put it in my Dell Precision 530 workstation, CentOS 4.4 Linux recognizes it, but no video comes out. Not even when I tell the BIOS to use that instead of the AGP card. Looks like I need to change the firmware from the Mac version to PC. Searching on Google so far hasn't turned up anything. Anybody know where to look? Or does anyone have a comparable video card for trade/gift? -- --- Dave Woyciesjes --- ICQ# 905818 --- AIM - woyciesjes "...Talking to you is like clapping with one hand."

HP 21MX/F and OS choices (was Lookee what I just got!)

by steerex＠mindspring.com

With that work done, it may be practical to boot your HP over a serial port at a reasonable speed, but loading a large ABS file this way can take a very long time (as things are). I generally don't recommend the serial boot method due to its poor performance. Then again, I think its nothing to throw together a PIC and some I2C eeprom and build little paper tape reader and punch emulators, and I can burn copies of any loader rom you wish. I found that serial booting the system to be the easiest way to get started. I don't recall which one but, one of the loader ROMS will work with the "high speed serial" card and read data off a serial link. There's no handshaking or error correction but, with a short RS232 link, passing data is not a problem. The ABS data format does provide checksum error detection so data errors will be detected. On many occasions, I have loaded HPBASIC and other programs over a serial link with absolutely no problem. The advantage to the serial link is that the only hardware required is a RS232 serial cable. Admittedly, it is not as fast as a parallel link but, who cares ;-) I had to write a PERL script to format the data before passing it to the 1000 but, that was fairly trivial. SeeYa, SteveRob

Abandoned Prime looking for new home (UK)

by james＠machineroom.info

Hi all, this is probably the shortest time I've owned a machine. Bought just a few months ago as a "project" I now have it to offer again. I simply don't have the skill to get this running. I've also got too many other projects :) It's ex Salford Uni Prime 2550. Comes with 2 disk drives, 1 tape drive, 3 boxes of manuals, 2 boxes of tapes, 4 5.25" floppy drives and a bunch of terminal lines. Pictures (including all the manual covers) are here http://www.flickr.com/photos/17208732 at N00/ Located in Southampton near M27 J7. It's yours for the taking. I'd like it to go to a genuine collector but will consider any and all interest! I can hang on to it for a few weeks but it's just taking up valuable space right now. If there's no interest in the entire system then I may part out boards, manuals, etc. As I understand it when I bought this it had sat for a year unused. Previous to that it had sat for a few years in a garage and been used occasionally and prior to that had been in the hands of the chap who rescued it from Salford. When I received it I had problems getting anything sensible on the terminal then things went downhill and I discovered the main 5V PSU had failed. I tried replacing that with an external 200A unit borrowed from my Cray EL but hadn't considered how many other signals are generated by the power supply. (MAN070 is available on bitsavers but this only covers the older Prime models - the power supply signals look the same but the VCP is very different). The ? 12 and +16 are all OK. I tried faking some of the power good signals and checked others (50Hz clock, etc). I even found one signal had broken on the backplane and have repaired that. Unfortunately without the manual for this specific model I'm stuck. In it's current condition it just sits with all front panel lights on and nothing on the console. CPU: As I say, the 5V supply has failed. I've patched several lines (the power good signals) inside the supply. I've had all the boards out, cleaned the connectors and vacumed the boards and case. I can include an 80A 5V supply if it's of any use to you (I'd hope 80A is sufficient. The 200A unit I was using is now back with the Cray!!) Disk drives: I found that the bolts holding the disk units in the casings were missing (a bag of "spares" was supplied which included the bolts and rubber mountings). I replaced the bolts before powering up, thankfully! One of the disk units powers up and spins. The other doesn't power at all. I removed all the dust too whilst the drives were out. Tape drive: Powers up and front panel buttons seem to "do stuff" but can't test any further. Tapes: These are all externally clean but a lot of the casings have cracked. You'll need some experience with 9 tracks to read these I expect. Documentation: There's a lot of very tidy manuals and also quite a few loose manuals in ring binders. There's also about 10 pocket guides. What is nice is the collection of history - there's administrator logs, service requests, etc. Floppy drives: I'm told the two original Prime badged units have failed. There's a couple of more modern replacements (and a handful of floppies) included - one of these should work! Without a working system I obviously can't test anything. Therefore, you should consider this as a source of spares or possible repair if you have the skill and/or manuals. I'm around most weekends for collection and can obviously give a hand loading. A standard SWB Transit does the job nicely. So come on, give the Prime a new home. Please :) James

Nine track tape BOT sensing foil

by ian_primus＠yahoo.com

After a recent fight with some Cipher tape drives, trying to boot a system, I managed to badly mangle the leader of my boot tape. Now, rewriting the tape isn't a problem, but fixing the tape is. I can cut off the mangled leader, but then there won't be enough tape left before the BOT marker. The BOT on a nine track is just a hunk of sensing foil, just like I remember from trying to repair eight track tapes (BTW, tinfoil and double sided tape _doesn't_ work on eight tracks). Rat Shack no longer sells sensing foil, surprise, surprise - so, does anyone know of a currently available solution? That metal duct work tape perhaps? I don't want to use anything that might risk damage to the heads though. Any ideas? -Ian

That the bulb glows at all with all the secondaries open is >to me a strong indication that something is shorted. > ---snip--- Hi That is not necessarily true. The transformer is an inductor and would normally draw quite a bit of current. It would be 90 degrees out of phase with the voltage across it but It is still current. It is current that makes lamps glow as well. To tell if the transformer had shorts, you'd need to measure the relative phase angle of the voltage on the lamp and the transformer. If it was 90 degrees, there was no short, just the open in the HV. For a quick check, measure the voltage across the transformer and then across the light. If these totaled together was greater than the measured line voltage, I'd say the transformer was most likely OK. If the sum was equal to the line voltage, it is surely shorted. Some 'oscope measurements on a dual trace would be more meaningful. Just the fact that the light lit is not enough to say that the transformer is bad or good.

what BS

How nice. It just happens to match the pdfs from a well known source. He's done this with other parts of the archive, but this particular add makes it sound like he actually did some WORK. At least the guy that's been selling bitsavers stuff in Israel puts the source in his ads.

Misc. stuff available for collection in Dublin, Ireland

by pcoghlan+cctech＠vms.eurokom.ie

Hello, Are there any other cctech members in Ireland? We are having a clearout at work and there is some old gear is going to be thrown out. If anyone wants it, they are welcome to come and get it. There are: One or maybe two VAXstation 3100s. Basic models - no model 76 or other high end ones. No disks. Should be working. Two VR299 colour monitors. (32kg each) One has no red on the display and a faulty on/off switch. The other is fairly ok. Two table top TLZ04 DAT tape drives. They both probably chew tapes :-( Some TLZ09 storageworks (green/brown) TLZ09 DAT tape drives. Condition unknown. Some storageworks (green/brown) canisters that once housed disks. Worked when they had disks in them. Some Decserver 200 terminal servers (8 port, LAT only) Some working, some power supply faults, some logic board faults. Two Dec DEMSB X.25 routers (with a few cables) Worked some years ago. Stored indoors since then. Two Satelcom Megapac X.25 switches (also with cables and manual) Seem to work. Not really sure what to look for though. A Livingston Portmaster 2e serial & ISDN "communications server" Faulty I think. Can test if anyones interested. A VT420 terminal. Dead as far as I recall. Can test if necessary. Maybe some other related bits and bobs. If anybody can take any of this, please contact me off-list. All are available for collection in South Dublin. I don't want to crate and ship anywhere as they are generally heavy, awkward and probably not of sufficient interest or rarity (although the X.25 stuff may be rare in some parts of the world, but I doubt if anyone's interested). Regards, Peter.

Analogue/vector character generator - anyone remember the URL?

by listmailgoeshere＠gmail.com

Hi cctalkers, A while back there was a URL posted somewhere on this list about a (1950s?) character generator which worked solely by mixing harmonics, with X-Y output to connect to a display tube. It could only generate the digits 0-9, but was a seriously impressive piece of kit nonetheless. I recently wanted to show this to a friend, and couldn't find it with any amount of Googling. If someone can remember this site, or has it bookmarked, I'd be endlessly grateful for the URL. Thanks, Ed.

s-100 cards, free for the price of shipping

by frustum＠pacbell.net

Spring comes early in Texas; too many days in a row of 80 degree weather triggers my spring cleaning subroutine. I have just poorly photographed and barely cataloged 28 S-100 cards, all but one, made by IMS -- Industrial Micro Systems. None are tested. My main criterion for picking will be whatever is easy for me, but I can't say that unfairness, prior exchanges, and unfounded opinion will also influence which board goes to where. That is, if I'm so lucky that anybody wants these. The boards are well made, although some have had parts removed (most are complete). None have been tested by me. I've had them for, uh, I guess two years, and the previous owner was given them some years before. You can see the index and pictures here: http://home.pacbell.net/frustum/s100/ Each card is in a 6"x10" antistatic bag, inside a padded mailer. They will be further padded with bubble wrap and boxed, and sent via USPS priority mail. You pay the shipping. I'll give people a few days to respond, then I'll get to work boxing and mailing. Please let me know which board(s) you are interested it, and if you have some specific need or use for one, let me know that too as it may influence the judge. Responding to the list instead of frustum at pacbell.net is an automatic 3/10th scoring deduction. If you are wonder why there are no cards 11, 22, or 33, it is because I used my children's number blocks to act as an index record when photographing, and there is only one of each number. :-) Below is the index: Box #1 ======================================================================== 1 - IMS A645 Rev B Z80 CPU; 2K boot ROM labelled "TST"; empty spot for RTC 2 - IMS C00451 Z80 CPU, (c) 79 3 - IMS A930 Rev C Floppy Disk Controller (NEC 765-based); also NEC 8257 (DMA) 50 pin connector (8"), (c) 84 4 - IMS A443 I/O Board, NS 8255 PIO, "IPL REV 1.4" EPROM, 2*GI AY-3-1015 UART, NEC 8253 PIT, one ear missing from connector, two empty sockets; not sure if they should be stuffed or not 5 - IMS A1021 Rev C, (c) 1983, 64K DRAM, with parity and parity error indicator All 9 DRAMs have been removed, but otherwise intact 6 - IMS C00451 Z80 CPU, Rev C., (c) 79 7 - IMS C00442 I/O Board, NS 8255 PIO, "IPL REV 1.4" EPROM, 2*GI AY-3-1015 UART, NEC 8253 PIT 8 - IMS C00480 4-Line Comm.

Pinout of RJ12 to minidin (PS/2) keyboard adapter for IBM 315x terminals

by pat＠computer-refuge.org

I know that a couple people who watch this list were wanting this info... I took the one RJ12 to minidin-6 adapter which I got with an IBM 3153 terminal, and pinned it out. The pinout of the connectors is from what I could tell, the "standard" pinout for each connector. RJ12 (tab down) MiniDIN-6 (socket) 1 .. 6 /--__--\ +------+\ / 6 || 5 \ |||||||| | | 4 3 | | | | \ 2 1 / +------+ | \------/ \______\| Ok, now the cable pinout: DIN RJ12 Use 1 2 Data 2 4 N/C 3 4 GND 4 6 +5VDC 5 1 Clock 6 N/C N/C Pat -- Purdue University ITAP/RCAC --- http://www.rcac.purdue.edu/ The Computer Refuge --- http://computer-refuge.org
