Documentation on the HP IPC

by vp＠mcs.drexel.edu

I have an IPC with HP UX 5.0 and HP Basic in ROM. The system has a built in HP-IB connector as well as an HP-IB expansion card. The system boots fine but I haven't had much success in getting the built-in floppy drive to read the floppies I have prepared (using a wide variety of systems and techniques). I am trying to use an external HP-IB dual floppy drive (an HP 9122D) but the IPC refuses to admit that the 9122 is connected. So, if anybody has tranferred images to a floppy, please let me know of your technique. I have PCs running many OSs (from MSDOS 5.0 to Windows 2000 and OpenBSD, FreeBSD and Linux). I also have Sparcs with Solaris 7 and OpenBSD. On the subject of documentation. If anybody has manuals for this machine please send me a note. If you don't want to part with them I can pay for photocopies. It is very frustrating to have the IPC just standing there when I *know* I can get it to work. Thanks **vp PS I suspect that the built-in floppy is double sided-double density, but anybody knows block size, interleave etc. of these diskettes?

MicroMint BCC52 BASIC controller

Does anyone have a manual for one of these? I bought one for $1 and now I know why. The 5V PS was putting out about 20 volts! I've fixed the PS and got the card talking to a terminal again after replacing about 6 ICs but I'm not sure of some of the features on it so I can't test it completely. Joe

Nice Manuals found up in the above garage storage area

by jrkeys＠concentric.net

I have not been up in the storage area for over 10 years and I found several items of interest up there; 1. AJ832 keyboard printer terminal operator's manual 2. IBM - Introduction to IBM Data Processing Systems C20-1684-2 a pretty cool book. 3.IBM - Introduction to Virtual Storage in the System/370 GR20-4260-1 4. IBM - An Introduction to Linear Programming GE20-8171-0 5. Data Storage System 370 service 6. HP 9825 Desktop Computer Quick Reference 7. HP 9825A Desktop Computer Operating and Programming 7. A notebook with the 9825 Customer Course in it: covers - introduction; mainframe; array variables; tape;strings; advanced programming; general I/O; HP-IB;9872 Plotter;9885 Floppy Disk; Matrix Rom. Also found some old IBM clear/blue reel tape covers and a few punch cards. Not 10 years old yet but yesterday at the thrift I picked up a Compaq Armada 7770DMT ( 233MHZ) laptop for $14.99. It was missing the powercord and CD-ROM drive. I was able to find a cord today but cost $20 at the second store I stopped at. I got it and so far the machines seems to work fine. I'm waiting to see if it will hold a charge.

Blank Paper Tape Question

by mhstein＠canada.com

FWIW, all the PPT I have & have used is/was blank, and the perforators punched the feed hole along with the data. However, I also have some edge-punched cards, which use the same perfs & readers as PPT, and these ARE pre-punched, presumably to avoid long-term drift across cards. However, IIRC, the perforator does not punch the feed hole when it senses a card instead of tape. So, technically no problem either way, although re-punching an existing hole is not usually a good idea. For the curious, EPCs (not to be confused with the tiny 96 col cards which also have binary round holes) are similar to 80 col TAB cards but are continuous, connected with perforations at the ends and stacked accordion-style. They go through the PPT perforator just like PPT, getting punched along the edge, and are subsequently separated and used like other punched cards. Sounds like you're embarking on an ambitious project; I think you'd need some massive solenoids. The way it's usually done is to drive the punch pins with a motor-driven cam and the solenoid interposers only select which pins are driven. I've still got some punches & parts if you're interested; threw some of it out since no one seemed interested (except Steve, who understandably couldn't wait :), and it seemed like more hassle than it was worth, but I think there's still some stuff in the pile that'll be a lot easier to work with than building a perforator from scratch, either complete units or punch blocks/dies. Mind you, if you enjoy that sort of challenge I wish you well! And how about a reader (or two)? mike ------------------------ Date: Fri, 8 Mar 2002 19:36:13 -0600 (CST) From: Bill Richman <bill_r(a)inebraska.com> Subject: Blank Paper Tape Question Does regular paper tape normally come with the sprocket holes pre-punched, or does the device that punches the data holes also punch the sprocket holes? I recently bought some "paper tape" from eBay, and it looks like the right stuff except it's totally without holes. I don't think I've ever seen "virgin" tape before, but I had the idea that the sprocket holes down the middle came with the tape.

I picked up some stainless steel flat and some rod of the appropriate diameter for the holes today, along with some solenoids for actuating said rods. I'm thinking of machining the stainless to make my own punch, but the lack of sprocket holes on the new tape has me confused. Do I need to add another solenoid and pin to punch a smaller hole for the sprocket, or did I just buy some odd-ball tape?

DEC distribution tapes - VAX vs RISC

by Mzthompson＠aol.com

I was looking through my DEC tapes to see what VAX, if any, were there. I found most tapes clearly marked RISC, and none marked VAX. I did find a couple tapes, early versions of Ultrix. They were not marked as for VAX or otherwise, but were dated around 1987 or 1988. So the question is when did the RISC series of processors come into use, and are these 'unmarked' tapes likely for VAX? TIA Mike Thompson

OT Mitsubishi Monitor Weirdness

by Lee.Davison＠merlincommunications.com

As an example, I use to work on some navigational transmitters with power output of a few hundred watts. There was a test jack for sampling the RF output and you hooked a scope to the jack. The gotcha was when you hooked the coax cable to the transmitter first instead of the scope. If you did that, the transmitter went down within seconds. This is rot! On a transmitter with even a few watts output the RF probe coupling would be -10dB or more, so even an open or short on this would give a return of -20dB. This is so small it can be ignored, in fact many antenna systems aren't that good. As a termination a scope is a very poor match for any low Z RF source it's impedance being 1Mohm or more so it wouldn't matter if you plugged it in or not. Also most test gear can't absorb any ammount of watts for any length of time, so if the port was a high power snif it would have to be terminated at the port with a high power attenuator which gives a good match regardless of it's terminating Z. The open circuit at the other end of the coax got reflected back to the transmitter as a low impedance and detuned it, and the monitoring circuits would detect the detuning and pull the plug. This depends entirely on the wavelength length of the coax. Did you use an exact odd multiple of 1/4 wavelength coax every time? can you remember the make/model of these transmitters?

DECstation Ultrix

by meltlet＠fastmail.fm

Hello all! I'd like to get in contact with anyone that has access to a DECstation 3100 with Ultrix. My problem is that I have a Cranfield DECstation which was built to run in a NFS environment. I've rebuilt the network scripts &c to get it to boot 'multiuser', but as it's missing the whole of /usr and refuses to present me with a login prompt (good thing really - lack of usr means I cannot change passwords anyway). I would really appreciate it if you have a working copy you could tarball /usr for me or point me towards somewhere with a publicly accessible archive...? TIA Alex

That's the way it is. The sprocket hole gets punched along with all the data holes. Even the TTY33-ASR did it that way. Otherwise you would have a tough alignment problem between the data and the "timing track". carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu

IBM 3840

by pat＠purdueriots.com

An IBM 3840 Tape System just came in recently at Purdue University Salvage and Surplus. The guy that works there (Don) said he would try and figure out a price for it. The system includes: 1) 1x3840 A22 controller 2) 2x3840 B22 dual-tape drive 3) 1x3840 B22 dual-tape drive with autochanger. The item was in 'unknown status', but appeared to be complete. I've asked him to hold off on scrapping the system until at least next Tuesday. If you're interested, contact me off list, and I'll try to see what he'll want for it(you can make an offer for him). Currently, I don't have any way to move it or store it (more than a couple days in my apartment that is) so the pickup would either have to be by Tuesday by you or I'd have to rent a truck to move it to my place for temporary storage (which I'd ask $20+truck charges for). If no-one's interested by next Tuesday, I'll tell him to go ahead and scrap it, so make up your minds soon... I'll post a price for it as soon as I find one out. -- Pat

I use to see this often during my tour as a television studio engineer. It all came down to one word: TERMINATION. I had forgot to terminate the video cables going into a monitor, or disconnected the monitor at the end of a chain. We all know to terminate the SCSI bus, and the other day there was a discussion of terminating the floppy cable as part of Dave Jenner's thread on multiple floppies. We also need to remember that any time you run a signal down any wire from point A to point B, it needs to be terminated in its characteristic impedance. If it isn't, some bad things can happen. As an example, I use to work on some navigational transmitters with power output of a few hundred watts. There was a test jack for sampling the RF output and you hooked a scope to the jack. The gotcha was when you hooked the coax cable to the transmitter first instead of the scope. If you did that, the transmitter went down within seconds. The open circuit at the other end of the coax got reflected back to the transmitter as a low impedance and detuned it, and the monitoring circuits would detect the detuning and pull the plug. On the back of my Mitsubishi Diamond Pro 20 there is a switch next to each BNC, used to terminate each input. If the monitor does not provide terminate switches, you can always try BNC T connectors and 75 ohm terminators. In a later message, Julius Sridhar <vance(a)ikickass.org> also wrote: > Never mind. The Clamp pulse setting was in the wrong position. I am curious to know if your monitor has termination switches. If so, how about setting the clamp pulse back to what it was and then terminating the inputs. If not, do you have the T's and terminators to try it that way. I would be interested to know the results. Mike

What this really meant was that some manager at NASA who was in the position of responsibility for these tapes didn't have the staff or budget to deal with them. A purely political issue, and not a technical one at all. I used be one of NASA's biggest supporters, and my dream was to work there some day. Year by year, my opinion of them has decayed until we get to how they dealt with the Delta Clipper. I've read the reports, and I'm convinced they deliberately crashed it because it was in comptetition for funds for their pet project, the venturestar (X-33). Which is now dead because they can't figure out how to make hydrogen tanks for the linear aerospike engine (very cool technology from Project Sun in the 1950s) that won't leak... -dq p.s.

Thanks, Bill! Just got home with my brand-spanking-old MVII and set about playing with it. It's indecently clean inside, cables all in good shape, fans all free and clean, cards well seated. I even managed to get them all back in properly, in order, and the cables connected right. So let me see if I got this right, as this is the first working QBus system I've gotten: Boards, in order: M7606-AF MV-II CPU (KA630-A) w/1M RAM & serial console line M7608-BP 4M RAM card for KA630 M7609-AH 8M parity RAM " " M7504 DEQNA ethernet M7546 TQK50 tape controller M9047 Grant card M8053 DMV11 Serial controller M3104 DHV11 8-port async serial DMA mux 2x M3107 DHQ11 " " " " " Storage: 2x RD53-A 70M Micropolis 1325 RD54 190M Maxtor XT-2190 TK50 95M CompacTape drive This means I would, if I had the distribution hardware for the DHQ11s, have 25 serial interfaces? (plus console) What exactly is the DMV11? "Synchronous communications controller" sounds like it requires a DMV11 on the other end as well. Everything VMS I've looked at says the DEQNA is unsupported in VMS >v5.2. Is that unsupported as in "don't call DEC/Compaq/HP", or unsupported as in "it don't work"? Am I stuck with NetBSD then? Does anyone know if NBSD will mop-boot over the DEQNA? I don't have VMS older than 6.2. Anybody have 2 breakout boxes for the M3107, and no M3107? We could equalize.... For that matter, if anybody needs the card, I'll just share. Oh yeah. It boots. VMS 5.2, but it's looking for the rest of a cluster, and apparently a lot of its filespace was remote. Bummer. Other than that, and the fact that I can't get it upstairs, it's a cool "little" box. You know you're over the edge when the lack of ethernet access in your garage is a problem. Doc
