7 track tape drives

by TRASH3＠splab.cas.neu.edu

Well, I went through the hardware I have at home and here is the list. Most of the stuff hasn't been turned on for over 10 years, probably more like 15. It has been in my workshop/basement, so it is pretty dry. The list of manuals will come later. The list of tape drives at work will come after that, but those (I think) are all 9 track, as are most of these. Anyway, here is the list of drives/controllers/formatters. Kennedy 9220 (192-9220-066) two cables, and a Kennedy 5427 mounted on the back. Formatter maybe. Cipher F880 1600/3200 BPI, 100/50/25 IPS IDT (Innovative Data Technology) TD11051, 800/1600 BPI, 45 IPS, 3 connectors, read, write, motion, 36 pin edge connectors, and a cable from (THIS) drive? bringing all 3 connectors into a single 50 pin edge higher densidy connector. Kennedy 9000 (192-9000-019) 9 track 800/1600 BPI, 37.5 IPS Cipher 910640 800/1600 BPI, 75 IPS 2 Emulex TC01/TU01 board pairs, QBUS 1 Emulex TC02 Formatters?: Pertec F6181-1/0085 Formatter, 2 boards, NRZI Read/Write, PE Read Datum 10341 Q/HP (Kennedy 120-0025-01) controller Datum Formatter 5091-120 Pertec f84942(0)/13.9, 901006-01 with R/W 7/9 NRZI Prime formatter 3101-0001 (Kennedy 9219-509), 3 boards inside As I said, I have been holding on to this stuff so I could someday set up a system to read the 15 or 20 tapes I have. All RT-11 or VMS, with a couple off an RSX-11 system. If there is something here that could help out with somebodys project, I would be glad to lend it out, or even give it away, just as long as it either makes it back so I can eventually read my tapes, or if somebody wants to read the tapes they can have all/any of the tape drive hardware. The list of manuals for the formatters/drives will be along shortly. Regards, Joe Heck

Heathkit H89 Video Question

by patrick＠evocative.com

OK, I'm working in unfamiliar territory... and since there seem to be a lot of video experts of late, this seems like the time and place to ask... I'm working on an H-89 that seems to have a problem in the horizontal drive on the video board. The unit powers up from cold to a good display, properly sized, and stable. After the unit operates for 10-15 minutes, the video breaks down, first by jittering slightly for 30-60 seconds, then it goes to a single vertical line on screen that fades to black. At this time, the filament on the CRT also stops glowing. If I leave the unit off for 20-30 minutes, it comes back with good video for a bit, then repeats the above. If I turn the unit back on right away without a cool down, there's no display/no filament glow. After tracing the (good) horizontal output signal from the terminal logic board into various part of the video board, and checking voltages where I felt I could reach safely in a hot set, I discovered that if I shot horizontal output transistor Q217 with cold spray I'd get video back right away. This unit is the one I posted about on cctalk a few days ago with the NOGDS board... when I got it, it had a AA battery inside for a clock board that leaked down onto the flyback transformer. The leak didn't appear excessive, and most of the "material" on the flyback must have dried long ago and was brushed away easily, leaving only a slight tarnish on the aluminum heatsink it's mounted to. My questions... 1) Although the flyback _appears_ OK, could the leak have caused some unseen damage that is now causing excessive current through Q217 and shutting it down? My limited understanding of flyback construction is that they are sealed units. It takes several minutes (10-15) before the failure is observed. Could a flyback failure allow operation for this long? How do I test this thing? 2) If I proceed under the assumption that the flyback is OK and Q217 is not... Q217 is a BU500: 1500V, 6A, 75W, SI-NPN. I normally buy from Mouser, DigiKey, and Jameco, but none of them seems to have this part, and I wasn't able to turn up anything useful Googling. A possible dealer or two in the UK, but for a $2-3 part I was hoping for a more-readily-available source or an equivalent. The closest I can find in the family is BU508A, which is 1500V, 7-8A, 120-125W (depending on whose specs you believe). Is that OK or too far out of spec? Does anyone know of US source for the real McCoy? Thanks for any help/advice! --Patrick

Digital DSM Disribution tape

by luc＠e2t.be

Can you tell me a bit more about this virtual tape creation? I have a few PDP11's working but they all run DSM It's the only Digital operating system I know - I never used RSX RT11 and so... I also have a 9track tapecontroller for pc and a Kennedy 9600 drive on it but this was used on MSM (the pc version of DSM made by Micronetics)and they controlled the drive direct without os intervention.

Apple 40SC tape details

by aek＠spies.com

I was able to read a tape this morning, after pulling the drive apart and making sure every last trace of the old pinch roller was cleaned >from the shaft. The motor runs HOT (which explains why the old rubber which was already soft liquified) and any little bit left will contaminate the cartridge. It is also souluble in isopropyl alcohol.. So be careful if you try to clean a tape head with a surviving (unlikely..) roller. It is a block-addessed device (like DECtape II's). So that it is saved somewhere, here are the specs: 3M MCD-40 rev 4.0 firmware (Apple Tape 40SC) 4848 blocks 8192 bytes/block (39714816 bytes total) The drive always retensions when you put in a tape. It will then do the usual tape head positioning, pause, then do one last read before extinguishing the red light. If the light flashes, tape loading failed. I've put some emails out to people I know who might have the actual specs/pgmg info, but I'm doubtful that they saved it.

AS/400 1991 9404

by ceby2＠csc.com

Folks -- I just wanted to take an opportunity to thank Sellam and Walter for the AS/400. Walter help me load the beast up, along with not one but three versions of the complete manual set. My back is much better now, if anyone asks. The system is home, and ticking over nicely. I've spent the balance of the weekend toying with it. I'd especially like to thank the guys for the opportunity at an IBM 5364. Walter had this sitting in the back of his basement and mentioned it while packing up manuals. I've had my eye out for such a critter for about two years. I haven't got a PC set up as a controller yet, but I'm very keen to take a crack at it. As always, I can offer myself as at least a physical resource for the S/36 gear, and now a bit of the OS/400. Anyone interested in a surplus set of manuals (and possessed of a strong back) reply quick. The surplus will be dutifully recycled. That should give you DEC geeks a warm and fuzzy since most of it will be reincarnated as toilet paper, I'm sure. Thanks again, Colin ---------- Forwarded message ---------- Date: Mon, 11 Aug 2003 12:06:33 -0400 From: W. E. Perry <wperry(a)fiduciary.com> To: donate(a)vintage.org Subject: AS/400 1991 9404 I have a 1991 vintage AS/400 9404, located in New Jersey, with original QIC120 distribution of system software through 1993 OS/400 v3 and *ALL* manuals. In storage since 1995, but working then. Would you want this machine or could you point me to someone who might? Thank you. Walter Perry

WTD: 74S188 PROMs or MFM data separator

by philpem＠dsl.pipex.com

Hi, I'm trying to build a data separator for a floppy disc controller board. The board uses a NEC 765 (aka uPD765) controller. I've found a schematic for a ZX Spectrum +2A FDC at http://simandl.jinak.cz/stranky/zxs/zxs_a.htm - this seems OK, except it uses a 74S188 fuse PROM as part of the data separator state machine. Does anyone have any spare 74S188s in their junkbox that they could be persuaded to part with? I'm also interested in the format the data separator supports - I can't tell from the state data if the state machine runs in FM or MFM mode. If it's FM, does anyone have a schematic for an MFM data separator that uses fairly standard (i.e. 74LS, 40xx, etc) ICs? Thanks. -- Phil. | Acorn Risc PC600 Mk3, SA202, 64MB, 6GB, philpem(a)dsl.pipex.com | ViewFinder, Ethernet (Acorn AEH62), http://www.philpem.dsl.pipex.com/ | 8xCD, framegrabber, Teletext "High voltage.

anyone have a working Apple 40 meg tape drive?

by aek＠spies.com

I think I've come up with something that will work. The outer and inner cross section of the roller is .7" and .5" so I dug around at Weird Stuff to see if any old DC2000 drives were close. The Colorado 250 appears to be, and with a bit of work with a small flat blade screwdriver I was able to remove the rubber from the .5" shaft. Now, I need to clean the goo out of one of the MCD-40 mechanisms and try it. This may be a workaround for the HP's as well. If someone has a caliper handy, I'm curious what the cross sections are for the roller in that.

DEC Fanfold Papertape Storage

by healyzh＠aracnet.com

What is the best way to store the clear blue plastic boxes full of DEC fanfold papertape? I'd been laying them flat, but that takes up quite a bit of space. I was wondering if it's safe to put them in a bookcase like a book, but I got to thinking this probably isn't a good idea for the papertape. Zane -- -- | Zane H.

The only reason I'm hunting for 9122 instead of 9121, is I thought > the floppy disks for the 9122 might be easier to find (they DO use different > media right?) The difference between the 9121 and the 9122 is that the former is single sided and the latter double. Apart from that they both use the DOUBLE density format which is different from the QUAD density PC floppies. So while you gain in capacity with the 9122, you still need to find these floppies. BTW note that while the 9121 is very reliable, there are quite a few 9122s with damaged heads. This has to do with the disk loading mechanism that gets stuck with age and if the user forces the diskette in, it hits one of the read/write heads. > Thanks for the tip!! I don't have too many old DECtapes, but when you say > old 40mb PC tape drive tapes, are you talking QIC-80 tapes? I have tons of > those. If not, exactly what tape do I go buy? CAREFULL! The HP-85 tapes (and the DECtapes) are NOT the same as the QIC-80 tapes. They look the same, to the extent that I was trying to insert one and getting annoyied when it wouldn't go in. > I saw note of that on your website.

Actually its not that complex. If you look at http://www.series80.org/Manuals/HP82929A.pdf you will see that most of the chips deal with address decoding. You can replace most if not all with a microcontroller (e.g. PIC). BUT, (there has to be a but, otherwise, I would have already pointed you to a page that tells you how to build one :-) The HP-85 bus is not TTL. I think the logic true is +6V and the clocks are like +12V. So you need more than a PIC. Like I said, its in my TODO list. Having said that, relocating the ROM executable may actually be easier. But (there's that word, again) when I tried to look at the CPU architecture, I freaked out. What the **** were they doing back then. This CPU is totally wierd, so understanding what is going on with that thing will take some effort. Anybody who knows/remembers HP-85 assembly? :-) **vp

Build your own PDP-8!

by bob＠jfcl.com

If you're one of those people who wants a PDP-8 but can't find one, don't despair - you can always build your own! The SBC6120 is a complete PDP-8 built around the venerable Harris HD6120 CPU and modern programmable logic devices. All parts used except the 6120 are contemporary, easily available devices. The entire system fits on a PC board 6.2" by 4.2" and has approximately the same footprint as a 3.5" hard disk. The SBC6120 has 64KW RAM, 32KW EPROM, a true KL8/E compatible console terminal interface, and a standard IDE/ATA disk interface. OS/8 device handlers are available for IDE interface, and the system will run standard OS/8 V3D. There's even an expansion bus so you can design and build your own daughter cards to plug into it. To find out more, visit the SBC6120 web page at http://www.SpareTimeGizmos.com/Hardware/SBC6120-2.htm Last fall, a group of about 30 people got together to order parts and PC boards for the SBC6120, and the results were better than I ever hoped. So far as I know, every one who assembled their SBC6120 got it working (a few people still have theirs on the shelf, unassembled, I'm afraid!). Some people even designed peripherals for it, such as Jim Kearney's cool I/O board which allows you to use a standard VGA monitor and PS/2 keyboard as a VT-52 substitute. http://www.jkearney.com/sbc6120/iob6120.htm And perhaps the best of all, we're now beta testing a real lights and switches front panel for the SBC6120. Visit http://www.sparetimegizmos.com/Hardware/SBC6120_Front_Panel.htm for a preview! Even now I still get enough inquiries about the SBC6120 that I have decided to purchase another run of PC boards and 6120 CPU chips. There's a fully assembled unit available on eBay now, http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2750838322 and Spare Time Gizmos is now selling bare PC boards, two different partial kits, and a complete kit at http://www.sparetimegizmos.com/Hardware/SBC6120_Orders.htm If you wanted to have your own PDP-8, then here's your chance!

Word processor--vintage computer or typewriter ?

by rogersda＠cox.net

Over the years I've worked on a number of systems that were sold as "word processors". They were all "computers" in the sense that they had the standard complement of CPU, memory, mass storage and the programming was loaded at boot time, as opposed to being in ROM. Some of them, e.g. DEC's WS-78, were general-purpose computers (oops! pardon me ... Personal Data Processors) that were shipped only with the word processing software. However, especially in the case of the WS-78/DECmate family, a DOS (OS-8/78/278) was available, as were a variety of compilers and interpreters, e.g. Fortran, BASIC, Dibol. I think I still have OS-8 on 8" floppies. Dale (the DECdude)

As this thing is taking up a serious amount of space I wont it out (I don't have any functional RP03 drives left) It's for free for the first PDP11 lover who wants it, does not intend to scrap it, and is capable of picking it up...

EBAY fraud alert

jumper settings for Chinon FZ-354 floppy

by redodd＠comcast.net

Hello all, I finally set up my SWP ATR8000 last night. This device allows an Atari computer to use standard floppy drives along with Atari proprietary drives. Included with the ATR8000 was an external floppy case with power supply that can hold 2 half height 5 1/4 floppies. It had 1 Shugart SA455 5 1/4 DSDD drive and I added (after hours of drilling and filing) a Chinon FZ-354 3 1/2 DSDD. I put the Chinon on the end of the cable set at drive 3. I removed the resistor pack from the Shugart and added a switch using old motherboard cables so I can change the drive id from 1 to 2. This is so I can boot CP/M from the Shugart as drive 1 or switch it to drive 2 and boot from an Atari drive. I had no trouble using the Shugart drive but the Chinon gave me a lot of problems. After a little research on the net, I changed the jumper from DC to RDY (this sounded like the answer) but I still got errors. The errors occurred after I rebooted and wrote to the same disk. Every file from the second write was messed up. The only jumpers left were MM and MD so I changed the jumper from MM to MD and it works great now. My big question is what are the MM and MD settings for, and how did this solve my problem? From what I've read, 3 1/2 drives don't have removable resistor packs and they somehow achieve termination automatically so that's why I put the Chinon at the end of the cable. Thanks for listening to my raving. By the way, does anyone have the CP/M disks for this setup for sale or for trade? Ralph

Monroe Calculating Machine

by vaxzilla＠jarai.org

Does anyone know where I can find out more about this old mechanical calculator? http://www.jarai.org/temp/monroe/0830_001-sm.jpg http://www.jarai.org/temp/monroe/0830_002-sm.jpg http://www.jarai.org/temp/monroe/0830_003-sm.jpg The unit is fully operational. With some inspiration from the Curta instruction manual, I've been able to figure out addition, subtraction, multiplication, and division on this device. I picked it up at a local yard sale today for a reasonable $30. So far, I've not been able to find much about this particular model. Most everything I can find talks about Monroe's later electromechanical calculators. The closest match I found is this one from the Computer Museum in San Diego, but the image is very blurry and there isn't much information about the calculator. http://www.computer-museum.org/collections/monroe_addc.html The next example is this one but it is a bit more streamlined than mine, so I'd guess it's a slightly later model. http://www.officemuseum.com/Monroe_Calculating_Machine_Co._NY_OM.jpg http://www.officemuseum.com/calculating_machines_pinwheel_other.htm The identifying marks on the calculator itself are the "Monroe Calculating Machine Company, New York, U.S.A." on the front and a number stamped in the metal underneath the carriage--41516--which I'm guessing is the serial number. The keyboard keys seem to be made from Bakelite. -brian.

There were a lot of word processing systems that, even though they had separate system boxes, the O/S was in ROM and couldn't be overridden. I would call that a dedicated-purpose "computer". I thought we were distinguishing between those and GP microcomputers sold as word processors. > I'd say that a wordprocessor that *looked* like a typewriter probably doesn't > qualify as a computer though; it's just a microprocessor-controlled typewriter. > The systems I worked on all used Diablo or Qume daisy-wheel printers for their output.

anyone have a working Apple 40 meg tape drive?

by aek＠spies.com

> Can you give me a model number? Apple Tape 40SC - Apple part number M2640 Did some digging on google's usenet archive, and people were trying to find replacements for the roller already in 1998. The mechanism is a 3M MCD-40 There was one message I've found that says that 3M sold off their tape drive division (or spun it off) as "GII" but I've not found anything more on them. Between bad tape formulations, and drives going bad, it is becoming really difficult to inexpensively recover data from 10 to 20 years ago that was written to tape.

Up for auction...

by kyrrin＠bluefeathertech.com

Hi, gang, Two of the items I just put up on E-pay may be of interest. First, there's a big lot (11 boards worth) of MicroVAX II CPU's and memory, which includes a "Controller of Mystery" (A System Industries CS-1) that I never did figure out the purpose of. Second is a pair of unused coaxial cables for VAX clustering. Easy enough to find. Just do a 'Search by Seller' for 'bftbell' (sans quotes). Thanks again for putting up with my occasional ads. -=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com ARS KC7GR (Formerly WD6EOS) since 12-77 -- kyrrin(a)bluefeathertech.com "Quando Omni Flunkus Moritati" (Red Green, aka Steve Smith)

Osborne 1 monitor questions

by dfnr2＠yahoo.com

Hello, Thanks to the help of several of you, I have, after reparing the power supply, been able to verify that the CPU is running, and using the .PDF service manual, am able to get a signal on the video pin (8) after replacing the contrast pot. However, the monitor still produces no output. I have a couple of questions: 1) Is there a SAMS or some other document that discusses the monitor operation? 2) What's the simplest way to use an external monitor for testing? 3) Does the monitor use the +12V line on the connector >from the CPU board for all its power, including the HV converter? Unfortunately I don't have an HV probe at the moment, so I'm being cautious about poking around the CRT. Thanks, David.

7 track tape drives

by TRASH3＠splab.cas.neu.edu

I also have been meaning to resurrect my 7 track drives and an 800 bpi 9 track, for the purpose of reading a couple of dozen useless tapes. I have at least 12 drives, from 7 track up to 9 track 6250 bpi, a couple of dilog and emulex qbus tape controllers, and two or three external formatters (for the older drives) I have some manuals from datum, pertec, kennedy, digi and maybe others, BUT I just don't have the time or inclination to start putting these together. A cooperative venture maybe? Joe Heck

IBM 60

by aek＠spies.com

The IBM 360/60 was never really a product.. try again. -- > BTW, weren't the 360/60 and 360/62 as evanescent as the 64 and 66? And wasn't there > a 360/70 that also quickly disappeared? The original lineup was the 30, 40, 50, 60, 62, and 70, with a vague promise of a 92. The 60 and 62 were the same CPU (2060), but different core-memory units (2360 and 2362). The 70 used hardware similar to the 60 and 62, but was all hard-wired, with no microprogramming, and used the superior 2362 core. The original S/360's took a long time to be delivered, and, a year later, some of the hardware specs were no longer competitive. The 60 was dropped altogether, and the 62 and 70 were replaced by the 65 and 75. Out of them all, only one 62 was ever shipped to a customer. At the same time, the 92 was dropped, to be replaced by a vague promise of a "90 series", later realized in the 91, 95, and 195. It was also about this time that the original 2.0-microsecond 30, with lights in the front like the other 360's, was largely superseded by the 1.5-microsecond 75(1), with lights behind a flat panel like a 1401; though the 76.-microsecond version was never officially discontinued, and was shipped in large enough numbers that there were 2.0-microsecond 22's offered (the 22's were reconditioned 30's, offered while the 370/115 and 77/125 were not yet ready), it was rare (I never saw one). But in the meantime, the need for large-scale timesharing had resulted in the announcement of virtual-memory versions of the 60 and 62, to be called the 64 and 66. As part of the same restructuring, these were withdrawn a month after they were announced, to be replaced with the 67. Of the original April, 1964, 360's, only the 40 and 50 ended up being shipped in large numbers.

Looking for a good home for my PDP-8/L (working)

by charlesmorris＠direcway.com

I no longer have the time or interest to play with my "University Computing Company" 4K PDP-8/L. It's a box and front panel but no cabinet - can't tell if it was a rackmount or tabletop. After replacing almost all the 7440's and a few other IC's, it seems to be fully working and "talks" with my ASR33 (desktop, no stand). Many panel bulbs were bad so I have replaced them with LEDs/resistors - glows red instead of orange/white but doesn't burn out! The only problem is intermittent read errors from the tape reader that prevent me from reading in a long tape like FOCAL or PAL. RIM can be toggled in and it reads BIN successfully. I also have a homemade NVRAM DF32/DS32 128K emulator (you may have seen the posts this winter) which also appears to be working but may need some modification to work with DEC software. It stores and reads blocks of data, anyhow, and is a 99% complete emulation of the huge rackmount DF32 + 3 DS32 assembly. The interface is the standard five-cable posibus and I had my own "paddle" connector boards fabricated to use with standard 40 pin ribbon cables. I will include the (Eagle format) schematic and board files and hopefully someone can complete the project. Emailed pictures available. I'd like to sell the whole works (8/L, TTY and disk project) to a good home ;) otherwise it goes on E bay. -Charles

7 track tape drives

by aek＠spies.com

As heard from previous messages the TU10 would be capable of reading 7 & 9 track tapes. -- A TU10 transport WITH A 7 TRACK HEAD can read a 7 track tape. Good luck finding one. For a PDP11, the interface was a TM11. There were master and slave TU10 transports. The parity and lrcc circuitry only exists in the first (master) transport. The interface between the drives is DEC's old 'negative' logic.
