> But I have no idea how big this 11/70 would be? A couple of points: 1. The 11/70 CPU itself weighs 400-500 pounds, in its cabinet with power supplies. Several fairly hefty guys can roll a CPU around and tip it into a trailer, for example. (Hi Elmo!) 2. An 11/70 by itself is pretty much useless. There's no memory inside the CPU box (in a "conventional" configuration) and there's no peripherals either. 3. Memory boxes weigh about 80-100 pounds each. A fully equipped system with core memory boxes (2 Mwords of core) requires 8 memory boxes. Solid state memory is more dense, and depending on exactly which generation of memory boards you might only need two memory boxes for a usable configuration. 4. Now you need peripherals. You'll almost certainly need a BA11 Unibus box tacked onto the CPU, this is another 70-80 pounds. And Massbus disk drives (as were mentioned in the original post) are the size of a washing machine and weigh several hundred pounds. You'll need at least two disk drives for any real usage. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

IBM 3270 PC

by dlw＠trailingedge.com

Got an urge to go to a thrift I haven't been to in a while and found what was labeled as a 3270 PC. Brought it home and opened it up. Looking at the boards inside I'd guess it was a 3270 PC as the label said. No keyboard or monitor. I'm guessing it used different ones than the normal PC. It has a hard disk, but have to pull it to see what type first and 2 half height 5.25" floppies. Not sure what software is on the drive. Anyone tell me anything else about this? Such as where to locate a keyboard and monitor, what each of the boards might be, etc. I can go into some detail on the cards if need be. Half appear to be normal drive controllers and serial port, etc. Then there is one with a BNC connector and two others that have a small jumper board between them. Should I even keep it? Hmmmm.... Thanks. ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

If you are looking for one keep your eyes open for DECserver 500 and 550's. The 500's use the 1/2 meg version and the 550's use the 1.5 meg.

St. Laurent, Quebec: Enemy of Classic Computing

by hrothgar＠total.net

I found this article in the September 22 issue of the Montreal Gazette: ST. LAURENT SUED FOR COMPUTER-FIRM RAID George Kalogerakis Gazette Justice Reporter ------------------------ A computer recycling firm is suing the city of St. Laurent for $36 million, saying the municipality destroyed millions of dollars in computer parts when it sent backhoes into the company's warehouse. Backhoes broke through the garage doors of A1 Vente Ordinateurs' building on Stinton St. on Thursday morning, the lawsuit says. The machines then used their shovels to scoop up computers stored inside and drop them into waiting dump trucks. This went on until A1 got a court injunction to stop the raid that afternoon. The city's crew returned Friday morning, and A1 obtained a second injunction Friday afternoon, halting all operations. St. Laurent city officials were not available for comment last night. The equipment was sent in as part of a zoning dispute between A1 and the city. St. Laurent has criticized the company for stockpiling discarded high-tech parts outside in an unsightly manner. It also claimed A1 was illegally using the site as a truck depot. So they went to court. In August, Superior Court Justice Vital Cliche ordered A1 to suspend operations and clean up the outside site. The company was given 30 days. If it didn't do the work, the city would and make A1 pay the costs. A1 general manager Mike Brown said yesterday the cleanup was done. It cost $8000 for trucks to haul away all the discarded parts, enough to cover a football field. Brown said A1 buys computer salvage by the truckload from bankruptcies and governments. What can be reused is stored in the warehouse while the junk is left outside. Court papers filed by A1 say the firm had complied with the cleanup order. But the city arrived Thursday at 7 a.m. and broke into the warehouse, which was not part of the judge's cleanup order, Brown argued. The 14,000 square-foor building is usually filled with 8-foot- high stacks of good computer parts, to be sold to brokers or repair shops that need parts. "They just destroyed it all and then took it all away," Brown said. He added about three-quarters of the computer stock had been hauled away as garbage by the time A1 got its injunction on Friday. What remained was about $10 million in stock. Brown said that's why A1 is suing St. Laurent for $36 million - $30 million for the computers that were hauled away and $6 million in damages. He said videotape and photographs taken by staff can prove the city acted maliciously. For example, he said, the warehouse is split in two. In the front is a display area with offices on the second floor while the back is the storage space. Workers sent by the city were pushing computer equipment off the second storey, where it fell 15 feet onto the concrete floor. He also claimed people were taking computer screens and putting them in their personal cars. -- Doug Spence Hrothgar's Cool Old Junk Page: hrothgar(a)total.net http://www.total.net/~hrothgar/museum/

Which series is most compact (sized for desktop or tower style) pdp or vax and only needs one wall power cord to run whole thing (including storage built in). Current draws snipped. Even I did manage to bull through my parents and did gotten that 11/70, breakers will trip every time I power just the cpu itself up.

I hated this apt even it's located in nice location, nice people. But I do have 2 negatives about this apt, floor is very bouncy for a uneven cement floor (too thin?) and too few breakers on too many circuits attached.

Zilog reintroduces enhanced Z80!

by allisonp＠world.std.com

<Just my observation, of course. Few processors would actually run that fas <for long, but those 8 MHz parts would do it for a little while if you kept <them cold. I've been running them at 8 and 10 mhz for years. The cmos parts do run cooler though even at 10mhz. To get real perfomance out of them (under CPM) you need to have a caching bios or the disk system will definately be the bottleneck. Also DMA is a must though the zilog DMA part never hit more than 6mhz the 8237-5 worked just as well and didn't have to run lockstep with the cpu. my 10mhz machine is on s100 and the CPU is not running the bios for disk IO thats a 4mhz z80 with DMA the the main system ram. the 4mhz cpu runs the hard disk and caches it (it actually pushes a teltek HDCTC as it's slow MFM) so the caching operation is invisible to the main cpu. CPM screams on that crate. There is an 8085 configured to do the same for the floppies and that caches at the track/cylinder level so the initial read is a bit slow but after that it's much better as the 32k LRU cache really helps. To date the fastest z80 system I've run (no waits) is 10mhz... I have a z180 that clocks faster but the dram is wait state so the effective speed is slightly less than 10mhz. Allison

Zilog reintroduces enhanced Z80!

by edick＠idcomm.com

I did get far enough along with some 55ns SRAMS in four 16K boards, to see clearly that running the processor at 12 MHz with floppies isn't nearly as good as running it at 4 MHz with a decent hard disk. The difference between my 8 MB ramdisk and my then 40 MB (formatted) HDD, was barely noticable, while both were considerably faster than the hot-rodded CPU with fast RAM. Just my observation, of course. Few processors would actually run that fast for long, but those 8 MHz parts would do it for a little while if you kept them cold.

<I suspect that it's only news to the slashdot crowd. "Two (or three) <decade-old architecture still doing real work" is news for 99% of the folk <out there, though it isn't to us :-). I agree. ;) However I did check zilog and the part is a new beast and does offer potential for some hot performance. Little things like 24bit linear address and an accumulate/multiply engine. With those goodies added yep, beats 180s182. The z80 has plenty of room to grow and unlike the 8080-->8088 transistion they learned from the z8000... it's z80 code compatable! This is one I'd like to play with... can you imagine CPM with 16mb ram at 30+mhz? Allison

TI Silent 700

by donm＠cts.com

I ran across a Texas Instruments Silent 700 Model 745 in a thrift store today. This is the middle sized one - about the size of a small portable typewriter - and appears complete (except for power cord) and clean. It even has part of a roll of the thermal paper in it. If anyone wants it for $20 plus shipping, contact me off list and I'll check if it is still there. (Good bet, I'd guess.) - don

Just a regular old 10meg xt with additional goodies to connect to mainframe. runs like a 327x mainframe console. a special monitor and keyboard were used. there may be a dongle plugged into the keyboard port; you can unplug that and use a standard xt keyboard. you'll get a 30x post error, but you can continue. some of the cards were for connecting via twinax (IIRC) and the special video modes that were required when you ran emulation.

There should be a sweep rate switch as well. lack of vertical deflection is either input set wrong, wrong gain setting or possible a input selector switch set for grounded(to zero the input). Heath would be a source for a manual in good likelyhood. Allison

As XTs go they were turbo (8mhz) and well made. The rest of the PS2 line was MCA bus (better) and incompatable at the card/bus level with the then PC world. Allison

IBM System/3 owners

by Henk.J.Stegeman＠is.shell.com

Hi, I had my S/3 up and running till end 1991. Then I moved house and since then is it stored in my garage. If you like the write small programs in macro/assembler and like to single instruction step through it, the S/3 is the best. In the extreme you can even single cycle the machine. I have all IBM program listings of the OS, RPG, FORTRAN, COBOL etc etc on microfiche. I also have the IBM program logic manuals. I like to hack little bit in the OS. B.t.w. are interested in a real S/3 mod 15 ? -----Original Message----- From: Richard W.

I would have been- I was told about various Sys/3x systems at a company, and they told me I could have had a System/3 model 15D if I wasn't a few years too late. But nice people that they were, they gave me a System/34, a System/36 (the big 5360 kind), two 3262 printers, two 8809 tape drives, a TDX-1050 tape controller/RS232 interface, and a Wang OIS-60 word processing system. I've fired up the printers and the tape drives and checked them out and I'm preparing to fire up the computers, S/36 first. Have you run your S/3? If so what do you do with it? I've always liked them; I have a picture of a S/3 and a S/34 hanging up at work. Richard Schauer

<> prevents rapid deflection changes.

Length of the tube was a function of deflection sensitivity, minimal effect on linearity directly. The linearity improvemnt was the flatter crt face as a result of the larger radius. <For anything higher you need electrostatic deflection, though. High speed <electromagnetic deflection would involve very high voltages in the <deflection amplifier output stages to overcome the back EMF from the <deflection coils. No, the inductance. You need a certain amount of current to move the beam and at higher frequencies the inductance of the yoke is the limiting factor in attaining that current. Faster electromagnetic scopes used very high amperes to turns ratios to keep the inductance to tolerable levels. For electrostatic tubes the capacitance of the plates combined with the leads (internal and external) were less limiting though above 20mhz or so they become very significant. However this helps lordtyran not one bit. Likely the problem he has is twofold, lack of experice using O'scopes and possibly a major balance problem due to internal misadjustment or component failure. We also have no idea if this is a low end recurrent sweep 5mhz cheapie or a triggered sweep cheapie. this would influence what suggestions could be made. Allison

OT: Semi-functional scope?

by a2k＠one.net

About 2 years ago a friend of mine gave me a "Bell & Howell Schools" scope. I put it in my basement for a few years until I've had time to look at it. A friend guided me through the alignment over the phone so I get my dot centered on the screen. But I can't get it to start (is sweeping the word?) I just get the dot. Turning the controls to any place other than where he told me results in the dot falling off the screen (to the left usually). I've tried to get results by connecting low-level audio sources including music and white noise, but still nothing on the display other than the dot. Any ideas? I need to have it working by 3rd period Friday because my friend is bringing an Arp 2600 analogue synthesizer to my chemistry class to demonstrate different wave forms and it will be a lot more effective if we can demonstrate the different waves if theyc an be seen. Oh, I forgot to mention that when I opened it up, there was a REALLY long CRT (I'd say more than 1.5 feet) that ran the entire length of the cabinet. Other than a bit of a rusty shield under one of the went holes, it was REALLY clean on the inside... but had several spider webs and dead insects. How something can be home to little creatures but not get dusty is quite beyond me... the only openings are the vent holes in the top, which are long skinny things that shuold have let it all the dust...

New CP/M implementations (fwd)

by donm＠cts.com

Jarek, you will note that I have forwarded your e-mail to the listserv for the Classic Computer mailing list. This is a group of people who are very interested in a wide variety of older - over 10 years old - computers af many kinds. A number are interested in CP/M machines, and there was a recent dialogue about a Spectravideo machine (whose model number I forget). I think that there will be interest in your work. - don ---------- Forwarded message ---------- Date: Wed, 15 Sep 1999 21:13:36 +0100 From: Jarek Adamski <yarek(a)sp7.zsk.p.lodz.pl> To: donm(a)crash.cts.com Subject: New CP/M implementations Hi! I found this address in CP/M-FAQ and I write because I have implemented CP/M 2.2 for some Z80 computers. 1. SAM Coupe, produced since 1989 in England by Miles-Gordon Technnology. Files are available on: "http://nautilus.torch.net.pl/zxland/" - "CPM22QED.lha" the install disk, - "ZXVGSusr.lha" description how to install, - "CPM22007RAR.lha" - recent version of some system files. 2. TIMEX FDD 3000, produced about 1985 in Portugal by TIMEX. This computer works with TIMEX COMPUTER 2048 and TIMEX INTERFACE. The install disk isn't available via Internet. 3. SPECTRAVIDEO 738 X'PRESS, produced in Austria by Prosystem (I'm not sure). This is kind of MSX. New versions not available due to lack of interest. (But I can compile new on request.) All above are compatibile. Have the same terminal (VT-52), the same format program (QFORMAT) and XDPB utility (QMOUNT). Use disks of 210, 410, 420, 820 and 1640kB - my own definitions.
