Hi I am looking for a comprehensive reference works for (non-PC-board) DEC hardware. Things with the part number pattern like : 70-xxxxx-xx 10-xxxxx-xx 12-xxxxx-xx 90-xxxxx-xx I'm sure you get the idea. If you could let me know about print, online, official DEC documents, or even DEC microfiche, I would be very grateful.

BA11-F boxer muffin fan source ?

by luc＠e2t.be

I 've replaced them by the dozens in those early days - this are industry standard fans, I think you can find them anywhere. Just make sure you have ball bearings, no sleeves. They are a bit nosier (who cares in an 11/70) but last much longer. In Europe we used Torin (UK factory) and Papst (Germany) but they were all 220V versions of cause... gr.

Displaywriter availiable

by Innfogra＠aol.com

Well, one of our local Goodwills has an IBM Displaywriter for sale in pieces. The CPU & monitor is one lot and the dual 8" Floppy disk drive is another lot. I could not find the keyboard or printer. they want $20 for each part if anyone is interested. Shipping would be expensive. If someone wants to look at it for themselves it is at the Centralia, Washington Goodwill. Too expensive by me. They may mark it down int a couple of weeks or so. Paxton Astoria, Oregon

Prime PT200 terminal capacitor values

by ian_primus＠yahoo.com

I got ahold of an old, nonworking, Prime PT200 terminal. It just displays a horizontal line in the center of the tube for a little bit, then a blank screen. The lighted keys flash on powerup, and the keyclick works. This leads me to believe that the the logic part of the terminal is still functional, and the video portion has lost vertical deflection. I took the back off and found a bunch of bulging, leaking electrolytic capacitors. Most of the capacitors are pretty common values that I was able to replace with some from my junk box, but there are two capacitors on the power module/board thing that are so corroded they are not even legible any more. I did my best to make out the values, but only one has any numbers visible at all. If anyone has the schematics, parts list, or a PT200 that still has good capacitors, I need the values of capacitors C19 and C15 on the power module/board. C19 _appears_ to be 1000uf @ 70v, but it's missing a couple numbers, and very corroded, so I can't be certain. C15 is so badly corroded that I can't even find any evidence of the original markings. Also, does anyone have a manual or any information about this terminal? There are two RJ-45 looking ports on the back labeled T1 and T2, and I don't know what they do... Thanks!

Epson HX-20 problem

by tmkwan＠pacific.net.hk

Does anybody know how to fix the classic protable Epson HX-20? This is my part of collections, I know it's work fine before. When I tried to switch on the machine last week, (it was after 15 hrs charged), the LCD didn't show up and there was no response on the contrast wheel. But I still tried to key in something, like "SOUND 10,10" and "LPRINT A", there was a beep sound and the text printed from the mini-printer. Then I plug in the AC adapter again and tried to switch 'on and off' many times on the startup switcher, the LCD worked again. At that time I thought the problem is solved. After one day later, the problem happened again, I needed to switch on and off many times to make the machine wake up. I am sure the machine is work on the first switch, because the computer responded my key strokes but the LCD still sleep. Really want to know what's happened on this machine and how to check/fix it? Thanks Man

Restore Disk Question

I have a >utilities diskette but it won't restore off the backup diskettes since the >computer thinks there is no hard drive any longer. The first thing is to get the machine booted with anything that has Disk First Aid and Drive Setup on it (Disk Tools floppy, or a bootable CD). To boot from the CD, put the CD in and hold down the C on the keyboard then turn on the computer and keep holding C until it starts to boot. (make sure caps lock isn't on as it only works with a lowercase C) Then run Drive Setup and see if it sees the hard drive, if not, the drive itself is toast, get a new drive. If it does see it, update the driver (its in the menus). After updating the driver, reboot using your boot disk NOT the hard drive. After the reboot, run Disk First Aid and attempt a Repair on the hard drive. After that, the drive still may or may not be bootable. If it still is not bootable, try reinstalling the OS, that should restore it to bootable state. -chris <http://www.mythtech.net>

HP front-panel keys

by rigdonj＠cfl.rr.com

John, I found my original HP 1000 keys and they are marked 4T1427. The CAT99 keys may be for the back door of the cabinet. Many of the HP 1000s were mounted in cabinents that had locking doors on the back. I don't know what the key number was but I think they had round heads also. I do know they were made of brass and I know that they were different from the FP keys. If you don't need the FP keys I can use them. I've made copies but they're not the same as the originals and aren't as nice. Joe > > I have several HP 1000s and two original keys but I'm not sure what you're asking. But yes the keys in all of the HP 1000s are interchangeable, at least in the six or eight machines that I've tried. I don't have one here but IIRC they are Corbin keys and they are brass with a round head. FWIW I just got some keys made and it was a real hassle. I tried Home Depot, Lowe's and a couple of othe large hardware places and they didn't have any blanks of the same type. I finally went ot a small local hardware store and they found some blanks made by another company (ILCO?) that they could make keys from. The new keys have a trapazoid shaped head like that usually used on house keys and they're nickel plated steel so they look completely different from the original keys. > > The locks on the HP 1000 simply hold the front panel closed.

FA: Cirris Signature 1000 cable Tester

by rigdonj＠cfl.rr.com

Last week I picked up a new cable tester. As a result I'm selling my old one. It's a Cirris Signature 1000 and it comes with 17 different cable adapters plus an AC adapter and two Cirris storage boxs for the adapters. These are GREAT devices! They make testing and reverse engineering cables a breeze. This one can test up to 128 different points (in .2 seconds!) and can even print out a complete wire list that you can add to a note book for a permanent record. If you've never used one, read the description at www.cirris.com. <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2539809546> Joe

He mentioned, that Sweet Micro Systems (who manufactured the board) sold 500 - 1000 to Nielsen ratings. I tried to get in contact with them, but this was not successful (i got no response to my request).

BA11-F boxer muffin fan source ?

by luc＠e2t.be

Hi, I had to look up a few words of your reply in the dictonary... You can (or could) do that for your own equipment, but I can't imagine me walking around with grease tubes and mineral spirits in the computer rooms of those days. Second, a fan costed about $10-$15 and a computer engineer about $80-$100 per hour. Third, you could't take the risk - if the bloody thing went down again the next 12 months, you smoked a huge cuban havana... and at last, this things are supposed to be impedance protected, but after being stalled for some time, more then once the windings were damaged... this was perhaps less common on the 110V versions, but our european 220V's had other behaviors. This was not ebay stuff you bought for a few bucks, but $80.000 - $100.000 equipment.

Cambridge (the UK one! :) computer companies

by julesrichardsonuk＠yahoo.co.uk

Hi all, I do occasional volunteer work for a technology museum in Cambridge - one of the things they're interested in doing (once some new storage is put in so that things can be moved around) is putting on an exhibit showing the history of computing in the Cambridge area. At present I'm really after suggestions of machines to look out for (and machines themselves if it's that or they go to the tip!) - other than Acorn, Sinclair and Torch from personal experience I'm not sure who was really active in this region, and know basically nothing of what went on in the 60's and 70's around here. I expect some of you UK guys know the history of the British computing scene pretty well though. I already have plenty of Sinclair and Acorn machines (I picked up yet another BBC Master along with a more modern A3020 and Risc PC only yesterday) but will have to be on the lookout for other systems of local significance over the coming weeks. cheers Jules ________________________________________________________________________ Want to chat instantly with your online friends?

Restoration: how far should it go??

by dwightk.elvey＠amd.com

Hi Well, some would consider what I've done to be real bad while others might see the reason behind my actions. I have an Olivetti M20. This is one of the rare desk tops that was made with a Z8000 processor ( there were a couple of s-100 boards as well ). I wanted to be able to bring up CP/M-8000 on this machine. The problem was that it didn't have enough memory. They sold two versions of the memory boards, 32K and 128K. I didn't think I'd ever see any 128K boards ( most everyone I know that has one of these machines has the 32K boards ). I did the unforgivable. I modified the boards to use 64K chips instead of the 16K chips. This required some cuts and jumpers since the boards were almost the same ( power planes are different ). While I was reluctant to do these mods, I felt that bringing this software alive was more important than preserving the original condition of the machine. After all, it is the software that completes the computer. The hardware is just the means. So shot me. Dwight

Restoration: how far should it go??

by kapteynr＠cboe.com

I agree. The whole historical significance of classic computers is the way they inspired tinkerer's everywhere. When you see my Altair, with its maze of prototyped wire-wrap interfaces, the monitor made from a converted B&W TV set, and the homemade "light pen" -- it brings all of this history into perspective.
