I will be in the Bay Area from the 7th thru 9th of May, part of my annual working vacation. If anyone wants to show off their collections of Big Iron - well I would't complain! Or if not, maybe just a pizza dinner rag chew jam session... I leave this Tuesday, but will be able to pick up email in Boulder in about a week. -- Will

Analog character generation for CRT's and American Used Computer/DEC Pr0n

by tshoppa＠wmata.com

I think last month someone here asked for a link to an article they had seen where X-Y waveforms were generated for CRT character generation. I believe the link they want is this: http://www.nixiebunny.com/crtgen/crtgen.html Also on David's web site, and by my accounting completely classiccmp-worthy is this picture (from a 70's National Geographic magazine!) of the proprieter of American Used Computer, standing between H960's filled with lots of DEC Mini's and peripherals: http://www.nixiebunny.com/sonny.jpg Tim.

Cleaning of Equipment

by jrkeys＠concentric.net

This past weekend I was given a IBM paper tape punch, that was and still is pretty dirty. It has what looks like animal waste on it and other strange stuff. What's the best way to clean this without removing any of the paint or labels? It has the gray base and stainless steel arm on top. Thanks for any help. John

Micropolis 1355 ESDI hard drive "sticky bumpers" Fixed!

by andy.piercy＠gmail.com

Allison, Well hats off to you, it worked! I have now fixed the faulty internals of the two faulty Micropolis hard drives by teasing out the black gooey mass that use to be the head park rebound bumper / end stops for each drive. They had turned into a black sticky mush and as you correctly identified were holding the heads from un-parking. However one of the logic board has also gone faulty so if anyone has a spare faulty drive they would be willing to part with the hopefully working bottom logic board please contact me. Drive type: Micropolis 1355 ESDI 5 1/4 full height (144 MB) Part no. 900568-11-4a Faulty PCB part number: 101942-04-3 B2 Eprom fitted: 800140-03-0 (But this is just for ref) Many thanks, Andy.

Quick survey on equipment

by roger.holmes＠microspot.co.uk

No CP/M machines, though I think I saw a Z80 softcard in a box of old Apple ][ cards I have lying about, though I know nothing about CP/M as I came from mainframes, minis and military computers directly to Apple. Two ICT 1301 Mainframes, one operational, the other dismantled but complete, offered to UK Science Museum but their new boss has ordered them to stop collecting big computers. The first one was offered several years ago (via the Computer Conservation Society) to Bletchley museum but they had no space for it. Since then I have restored it to an operational state and am now working on getting the peripherals working so that I can read the software and get it onto modern media. Then will work on the rest of the peripherals such as the line printer and online card punch. Manufactured in 1962, acquired late 1970s. Price new about a quarter of a million pounds each. Need 700 square feet floor space each, weigh 5 tons each, consume 13kVA three phase (440V). UK101 single board computer (8k static RAM, mono video output, keyboard, casette tape storage) Two or three Apple ][ europlus. 48K, twin floppy drives, dozens of cards, hopefully including a Microspot serial/parallel card (AKA MicroPeripherals Zappler) which I designed. An Apple /// (probably non operational), maybe two plus a Profile hard drive. An operational Macintosh XL (AKA Lisa 2), plus one which has not been powered up in 5-10 years. Odd Macintoshes, can't remember what, we had a chuck out a while ago and I'm not sure what is left. A Titanium Powerbook, so once a year I can run Civilisation 2 and a few other games, which won't work on Intel Macs. Work machine: MacBook Pro, 2 GHz Intel Core Duo. Roger Holmes Also collect classic cars and hoard all sorts of interesting junk because its easier than selling it (e.g. never sold a car).

SGI hinv...

by lbickley＠bickleywest.com

There was a comment regarding the SGI "hinv" (hardware inventory) command and other UNIX systems. I've attached inline a "hinv" of my Onyx2 system. As you can see, it gives both hardware information as well as serial and part numbers of all boards in the system. In addition, I've also provided a "gfxinfo" command - which inventories and describes the graphics hardware on the system. There are other "info" commands which describe other system options - but I figured this would be enough to get the idea... ---------------------------------------------------------------------------- hinv -m IP31 Board: barcode MJT049 part 030-1523-001 rev C IP31PIMMR12KS Board: barcode MJS498 part 030-1423-002 rev H MODULEID Board: barcode K0010378 part rev IP31 Board: barcode LAM652 part 030-1523-001 rev C 4P1G5_MPLN Board: barcode DAW270 part 013-1839-001 rev E IP31PIMMR12KS Board: barcode LAT574 part 030-1423-002 rev G GE16-4 Board: barcode GMR170 part 030-1398-001 rev B DIVO Board: barcode DDE075 part 030-1046-002 rev H BASEIO Board: barcode GKN285 part 030-0734-002 rev N MIO Board: barcode GJJ660 part 030-0880-003 rev F 4 400 MHZ IP27 Processors CPU: MIPS R12000 Processor Chip Revision: 3.5 FPU: MIPS R12010 Floating Point Chip Revision: 3.5 Main memory size: 3072 Mbytes Instruction cache size: 32 Kbytes Data cache size: 32 Kbytes Secondary unified instruction/data cache size: 8 Mbytes Integral SCSI controller 0: Version QL1040B (rev. 2), single ended Disk drive: unit 1 on SCSI controller 0 Disk drive: unit 2 on SCSI controller 0 CDROM: unit 6 on SCSI controller 0 Integral SCSI controller 1: Version QL1040B (rev. 2), single ended IOC3 serial port: tty1 IOC3 serial port: tty2 IOC3 serial port: tty3 IOC3 serial port: tty4 IOC3 parallel port: plp1 Graphics board: InfiniteReality2E Integral Fast Ethernet: ef0, version 1, module 1, slot io1, pci 2 Iris Audio Processor: version RAD revision 7.0, number 1 Origin BASEIO board, module 1 slot 1: Revision 4 DIVO Video: controller 0 unit 0: Input, Output IOC3 external interrupts: 1 ------------------------------------------------------------------------------ /usr/gfx/gfxinfo -v Graphics board 0 is "KONAL" graphics.

The advantage of being exDEC. I had a lot of stuck rd53s and built up a lab MicroVAX system by fixing a few when noone could get their hands on stuff (budgets). I figured they were officially dead and the worst that could happen is they get deader. I'd scrounge bits and peices and trade RD53s as needed with other groups to get the needed bits. My boss was surprized when a request for node address came back to her for approval for a system under my desk. When she saw the BA123 with 3 RD53s and a RD54 she wanted one, I produced that one in about a week. Getting her the 19" color monitor was tricky though. ;) >I have now fixed the faulty internals of the two faulty Micropolis hard >drives by teasing out the black gooey mass that use to be the head park >rebound bumper / end stops for each drive. > >They had turned into a black sticky mush and as you correctly identified >were holding the heads from un-parking. > >However one of the logic board has also gone faulty so if anyone has a spare >faulty drive they would be willing to part with the hopefully working bottom >logic board please contact me. You will likely have success finding a board or another complete drive (with stickies). Now that you know how to fix them you may find an excess of the drives results. ;) Allison > >Drive type: Micropolis 1355 ESDI 5 1/4 full >height (144 MB) >Part no. 900568-11-4a >Faulty PCB part number: 101942-04-3 B2 >Eprom fitted: 800140-03-0 (But this is just for >ref) > >Many thanks, > >Andy.

Old IBM mainframe crt/monitors

by halarewich＠gmail.com

hi guys I was just remembering back about 20-25 years ago when i was in my 10-15 years old going to work with my step dad who worked at a mining co that had a bid datacenter and was awed at the computer monitors that were hooked up to the mainframe the bulk of the monitors were these great big ones that sat on the desk they were probably 2'wide X 1 1/2'-2'high and about 3' deep the base cume up about 6" then curved out so you could see the main screen like so forgive the drawing ----------------- ! ! ! ! !__ ! ! ! ! ! ! ! ------------- CROSS SECTION I would like to know what motel that was all i remember it was stamped IBM and if there are any pic's arround then a couple years leter i remember we got these lcd plasma type displays about 1985 or 86 about 2.5 feet tall 2.5 feet wide but only bout 1 foot thick and they were neat because they could be 4 small monitors or 2 or 1 big monitor but they only had one color flouresent orange im trying to figure out what these are to tx 4 your time Chris

Outright removal is the easiest. You hear a clunk when the head returns but I've nver had any that showed adverse side effects from that. Allison
