Transfer of Files From RSX-11 (fwd)

by jpl15＠panix.com

I wrote this gentleman off-list (as the S/N ratio is rather out of hand just now) and asked some basic questions... mainly trying to find if he had just a disk, or the who thing. Follows is my reply to his response; if anyone can jump in with more or better info for him, please respond directly and cc: the list. The meta question is: what's he gonna do with the system once the data is mined??

Ah... this makes the process *much* easier! A bit of info now would be: what is the model of your DEC system? (ie PDP 11/23, VAX 11/750, PRO350... etc) > > I have checked Kermit but I could not find this S/W > there. Might be my process was wrong. Hmmm... a lot of RSX systems had Kermit as part of the Distribution Kit.. you can try: MCR> DIR kerm*.*,* but if your disk is big and you CPU slow, this can take upto an hour to complete. OR, you can use a Terminal Emulating program on your Wintel machine (I use VanDyke's CRT on my IBM Thinkpad running Win2K). Then, find the file(s) you want, and use the RSK 'type' command to list them to the port you are attached (logically and physically) to. Use your terminal program's "logging" or "screen capture" function, and... there you are! The files are safe on your PC. (This assumes you have a multi-port set of serial terminal connectors attached to the computer. This procedure can also be done using the PC terminal emulator attached to the DEC system console port. The object is to list the files as an ASCII stream and capture that listing on the PC's HD. This will work with any storage media on your DEC computer, HDs or Floppies, by the way. Please write to the classiccmp list during this process, and we will all try to help out as much as possible. I will also forward this correspondence to the List. Cheers John

TLC Ideas for LA120 Keyboard?

by jss＠subatomix.com

Well, my DEC LA120 is almost perfectly operational. Its only problem is a set of keys that do not work when pressed. I'd like to fix that. What I see when I remove the keycap is a square plastic housing that slides vertically within a larger square plastic housing. The smaller housing slides down when one presses a key. A spring below the smaller square housing pushes the housing back up when the key is no longer pressed. Up through the smaller housing shoot two electrical contacts. The contacts are fixed and do not slide with the housing. When the key is up, a plastic bar across the middle of the smaller housing holds the two contacts apart. When the key moves down, the bar moves down and no longer holds the contacts apart. The contacts touch and complete a circuit, and the LA120 senses a keystroke. Top view (key not pressed): +-A------------------+ | +-B-----+-+------+ | | | | | | | | | | | | | | | | | D |C| E | | | | | | | | | | | | | | | | | +-------+-+------+ | +--------------------+ Side view (key pressed): | | /\ | | A B / \ | | | | D E | | | | / +--+ \ | | | | / |C | \ | | | | / +--+ \ | | | +----------------+ | | /\/\/\/\F/\/\/\/\/ | +--------------------+ A = Outer (fixed) housing B = Inner (sliding) housing C = Bar that holds contacts apart when not pressed D = Electrical contact E = Electrical contact F = Spring The problem is that the circuit isn't being closed when the key is pressed. If I stick a screwdriver in there, bridge the gap between the contact, and thus close it manually, a keypress is sensed. Actually, it senses several keypresses very quickly, probably because of the noise caused by the conductive screwdriver scraping across the contacts. When I press the housing down, the contacts *appear* to touch, but no keystroke is sensed. So I figure there are either or both of two possible things going on: (1) Tiny space between the contacts (2) Nonconductive material (corrosion? oxidation?) on the contacts Two keys were fixed by using the screwdriver to bend the contacts toward each other in the hopes of creating more force pushing them towards each other. The ENTER key does not seem to be responding well to that treatment. One thing is for sure. All this stuff is so tiny and hard to get to that it is difficult to work on. Any suggestions? -- Jeffrey Sharp

looking to get a VAX 11/750

by jwillis＠arielusa.com

Who was your contact on the east coast? I'm in New Mexico and have a VAX 11/750 that I've been struggling to complete. If it was $250 for shipping + $150 for the VAX, I'd be quite inclined to let mine go for $250 and then spend the extra $150 to get a complete one from the east coast person. -----Original Message----- From: pzachary Sent: Tue 2/18/2003 11:13 AM To: cctalk(a)classiccmp.org Cc: Subject: looking to get a VAX 11/750 It seemed to me before I called up someone out on the east coast and bought a VAX-11/750 for $150=/- then spent $250 or so shipping it that I should try the list. I want a VAX 11/750 for old times sake and as a peripheral for my pdp-11s... anyone have one for sale/trade/...? Thought I'd rather a local had the money to buy inflated pdp-8 spares or something than giving it all to a shipping company. I'm located in santa Cruz CA and am willing to pick up within a couple hundred miles. I would really like to get out of this for less than $400 (really $250 seems like a fair price(that's what they sold the one I ran out from under me when the funding ran out and I was on vacation for (rant ends)) but I'll take what I can get) further, I have much of a card set and a power supply or two, so if I get a incomplete one that's O.K. thanks, Pavl_ sorry about the joining in of the rant/flame thing RE:politics, I can usually restrain myself but sometimes when it goes on... and to respond to the digest-delayed list makes it worse I know(I've at least changed the last bit) [demime 1.01a removed an attachment of type application/ms-tnef which had a name of winmail.dat]

Dying VaxStation 4000 VLC - help? - fixed!

by mtapley＠swri.edu

All, The result: Replacing the electrolytic capacitor on the lower leg of the voltage divider feeding the reset comparator did the trick. The system is now up and running normally (but I've forgotten the password! Hope I wrote it down, else I'll have to re-build the system...). Many thanks to Tony D. (who guessed right the first time), Toth, Peter, Antonio, and anyone else I've forgotten. Sorry it took so long to report - I just this morning got my friend at work to put the new capacitor in place. I still have the presumed leaky capacitor he took out, but have not tested it. Details of the problem are (presumably) in the archives; in brief, the primary symptom is that the system won't come out of reset (the code LED's on the back won't start flashing) on power-up, or falls back into reset peridically while running. Anyone with similar problems, I'll be happy to relate my full story and send pictures if desired. I *love* being on this list! Thanks again to all! - Mark

OT: OT: OT: Re: Gateway 2000 Handbook 486 question

by Robert_Feldman＠jdedwards.com

That was Win 3.0, which was the last that could run on an 8088/8086/80186. It had Real (Win /R), Standard (Win /2 or Win /S), and 386 Enhanced (Win /3). Win 3.1 is restricted to the two Protected modes (Standard or 386 Enhanced). -----Original Message----- From: Doc Shipley [mailto:doc@mdrconsult.com] Sent: Tuesday, February 18, 2003 1:10 PM To: cctalk(a)classiccmp.org Subject: Re: OT: OT: OT: Re: Gateway 2000 Handbook 486 question On Tue, 18 Feb 2003 vance(a)neurotica.com wrote: > On Mon, 17 Feb 2003, Chad Fernandez wrote: > > > I did try Win 3.1 on my old 286-12, with about 1-1.5 megs of memory. > > It was so slow, it took it a few minutes to finish crashing :-) > > I don't know what you were doing wrong. I did quite a bit of useful work > on Windows 3.11 running on a 286-8 with 1MB RAM. Ran just fine. ISTR that Win3.11 had a switch to run either in "Real" or "Standard" mode. I may have the terms wrong, but one was for low power machines. Doc

Help with my PDP 11/73

by chu＠verizon.net

Hi, Thanks. Big success and then a new problem. I took out the top three levels of my cards and reseated them. There's a lot of corrosion on the contacts so it inserts only with difficulty. Anyway it booted up ONCE and I saw lines indicating that RSX11-Mplus was starting up. It went through an initialization script and then I/O to the console terminal died. I have not been able to get any more output from the console. So my next problem is to figure out what happened. Progress is being made. One big good thing, at least my disk has to be working.

RL02 docs in PDF (re:11/44)

by jwest＠kwcorp.com

I noticed the docs on maincoon for the RL02 were all in tiff format. I got them all converted to pdf in case someone needs them in that format and doesn't have the tiff to pdf conversion utilities. If more than a few people ask I'll put them up on classiccmp.org. Jay West
