Olivetti M24 monitor

SGI Indigo..

Its from a university who are pretty anal about keeping > all of these things together. so hopefully it will turn up.. Maybe this will help: there are basically 4 mice that have been used on SGIs. Some early 4D's used an optical mouse made by Mouse Systems, rather rectangular in shape; it's possible to convert some old Sun optical mice to SGI use and vice-versa (see the 4DFAQ aka "This Old SGI" for details). BTW, having the mouse work correctly on one axis but not the other is a common symptom of using a mouse pad with the wrong line spacing. Some people have in the past incorrectly attributed this to "one of the LEDs not working", but in fact the perceived non-illumination is because one LED is visible red and the other is infrared. Most Personal Irises and the original Indigo (both R3000 and R4000 models) use a Mouse Systems mechanical mouse, which has a 6-pin miniDIN that plugs into the keyboard. This is basically a serial mouse. It's a beige colour, same as the keyboard, with about 32" of cable, part no 9150800. Benjamin, are you sure you've not misread the last digit? I've checked half-a-dozen mice in case I had any variants... The Indigo^2, Indy, and later machines use a PS/2 type mouse, also 6-pin miniDIN, which plugs into the machine (which has two PS/2 ports, one for the mouse and one for the keyboard). The first ones were made by Mouse Systems and look just like the earlier Indigo serial mice, except that they are normally granite (grey) in colour, have a much longer cable -- about 105" -- and a different part number: 063-0001-001. The very earliest ones, however, were beige (the earliest Indy keyboards were beige). Later Indys, and O2/Octane/Origin/Onyx2 and the like, were sold with a PS/2 mouse made by Logitek. It's a rebadged 3-button Pilot mouse (equivalent Logitek type M-S35), also granite coloured, part no 063-0009-001. -- Pete Peter Turnbull Network Manager University of York

ASR33 questions

by ekklein＠pacbell.net

I just received one of William's ASR33s and it appears to be in good working order. I am not at all familiar with these machines so I have a few questions about their operation and interfacing. First off, when I power on this unit the "main" motor doesn't run. It turns when moved manually, but it won't move by itself. Depending on the motor position at power-up (I think) I sometimes hear what sounds like a warning buzzer. Is there something I'm doing wrong? How would I run this machine in "local" mode? Once I figure out that this machine is working (I assume the problems are mine and not the machines) I'd like to hook it up to my Altair (which is now running great thanks to Dwight!). How would I go about doing this? I'm guessing I'll need some sort of box to interface between the TTY and RS232, but I haven't yet found any information on that. Can anyone point me to an article, website or some other source of information on this? If I manage to get that all done, is there anyone on this list who has software on paper tape that I could get copies of? I'd be most interested in a BASIC variant and any BASIC programs that could run on it, but anything else would be great. What am I missing? Is there anything else I should know? Thanks! Erik S. Klein www.vintage-computing.com

Great HD Guide

by jrkeys＠concentric.net

Stopped at a new thrift in the area Friday and picked up several books (19) and one is titled The Hard Disk Technical Guide by Douglas T. Anderson PCS Publications March 1991. In it all list of various hard drives and their spec's but the best part is the listing of various controller cards and their jumper setting's (93 pages). There is lots of other good information in it and it's a total of 224 pages long and cost me a big 20 cents plus tax. This will help a lot in working with older cards when trying to get the right jumper settings. If anyone needs help with a card email me and I will see if it's listed in the book.

PDP-9 lives again....

by hansp＠aconit.org

Some 20 odd years after it was decommisioned we finally got our PDP-9 to boot software off an old DECTape. Advanced Software System version 5A came up today for the first time on our restored -9. This after a long and frustrating summer when we spent over 100 man hours chasing a processor fault which resulted in the execution of the saved PC value after an interrupt (instead of the word after the saved PC value). Turned out to be a misaligned delay circuit which caused a reset signal to arrive late and provoke all sorts of havoc in the processor while nicely reseting all the tell-tales. Seems like the memory and processor hardware is quite stable now. We have two DECtape units attached with two more units availabe to be attached. Further debug on the DECtapes and learning the software will be followed by attachemnt of TU20 mag tape units. If anyone knows of an available (and cheap) large X-Y plotting scope preferably somewhere in europe we would be very interested in hearing >from you. We have a graphics controller but no large screen. With the screen, the DECtapes and the TU20's this is going to be one impressive system. We also used the -9 for the first time today to try and recover an image >from an old Elliott 903 paper tape I was given in the UK recently. Due to operator error that attempt failed but I fully expect to be able to get a tape image this weekend. -- hbp

Old DOS software

by tony＠baechler.net

Hello all. I am looking for MSDOS software from the early 1980's. I have some leads, but not many. Specifically, what I want is the entire PC-BLUE, PC-SIG, and any other similar collections. I would prefer to download them >from someone and burn my own CDs but if you have them on CD-ROM and you are willing to sell that is fine. Here are what leads I have. I looked on google for PC-BLUE and found that oak.oakland.edu apparently had everything but are long gone. I used to download from there in 1997 but apparently there are no full mirrors left. However, ftp.mirror.ac.uk has several disks but nothing past 1989. I know that there were more than this by a 1991 post I found from the old simtel20 indicating that volumes were still being added. I would like the full set, even files into the 1990's. Regarding PC-SIG, google showed almost nothing at all. I tried every set of keywords I could think of, but there is very little to be found. Again, ftp.mirror.ac.uk had quite a bit but cut off at 1989. I know they had at least 1,000 disks, probably over 2,000. I used to download them from a local BBS many years ago, so I know they sold a CD-ROM. If I could buy or download that somehow I would be very happy. They are now out of business. Amazon might have it but I doubt it since they cannot get them >from the publisher and have been known to offer items which they did not really have. Finally, I found another directory called COMUG which I assume was another user group. Does anyone know if there are any other disks from them besides those posted? I am in the US. You can write either on or off-list if you can help. I have no ftp upload space unfortunately. I can use .iso CD images. Sorry if this is off topic, but the FAQ seems to not be working.

Looking for SIMMs for PS/2 P70 386

by rschaefe＠gcfn.org

Thanks to the local college boyz, I now have a slightly misused P70 to play on. The previous owner was kind enough to break off the retaining clips when he pulled the memory, but other than that it seems to be usable. Booting without any memory elicts a `211' error early in the POST, and booting with one or more of 8MB (IIRC) SIMMS gives a 225 error. I did a little research, and it seems that the max SIMM it'll take is a 2MB parity part, I know don't have any of those. Anyone happen to have a spare 8MB kit? Also, I'm looking for the S/370 card for it, if anyone has an extra they'd like to get rid of. ^_^ Bob

Is there something I'm doing wrong? How would I > run this machine in "local" mode? Sounds vaguely similar to a problem I have (occasionally) with mine. Sometimes the motor noise starts to rise and fall slightly, as if the motor is struggling; eventually it blows the fuse. In my case, I suspect the problem is something binding (needing adjustment) and/or needing correct lubrication. There are lots of parts that need lubrication, and it's definitely NOT a case of oiling or greasing everything in sight! There should be a knob on the front right. Turn left for online, centre off, right for local. > Once I figure out that this machine is working (I assume the problems > are mine and not the machines) I'd like to hook it up to my Altair > (which is now running great thanks to Dwight!).

Probably ;-) But I'd get the machine working in local mode before you start worring about interfacing it.

It's a small keyboard and 80x8 line display. built in software seems to be a word processor, spreadsheet, calculator, database (1 text field), Phone numbers, spell checker. seems to be aimed at the ed market. I picked it up because there is a legend on the outside that suggests it runs some kind of BASIC, but the option turned out to be a keyboarding drill. Anyway, found lots of surface stuff on the web, but I am interested in: 1) what processor 2) pinout of IO port on back 3) Can I add a BASIC (I don't mind if I can junk the WP et all at the same time) here's the Place that made it: http://www.perfectsolutions.com Hey Sellam, what would you want to trade for it? : ^ ) Thanks! ron

id this Data I/O part

by rigdonj＠cfl.rr.com

I found a small circuit board marked "Data I/O", "702-1072" and "Plug in Adapter". There is also a paper label on the board that says "910-1347-1 E". It has two 16 pin DIP ICs on it. I can't see their part numbers because they have paper labels on them. The board mounts using three metal standoffs and has a row of 14 pins along the left and right hand edges. Can anyone tell me what it is? Joe

DG Aviion & 3 phase supplies

by Qstieee＠aol.com

While I agree with the other answer that often there are several single phase supplies inside, connected to separate phases, note that there are some commercial solutions if you truly have one big power supply with a three phase primary on the transformer. See http://www.phaseconverter.com/ and http://www.phase-a-matic.com/ for example. These devices have a long life time and can be found on industrial surplus markets (which of course are on the web too)
