There is more than one "main program". There are command line tools that do the real work and a GUI front end for them. I only care about the former, I'm fine with never being able to run the latter - I don't need no fucking sissy GUI shit. MS

NEver having seen this unit, I can't offer specific help, but I would at least start by opening it up. Look for _intenral_ fuses, check them, but don't necesarily replace them if they're blown. You do want to see how violently they belew -- if the glass is shattered or blackened by a film of metak, then the the thing really took some current! It would also be useful to know if this is a switching supply (look for electrolytics rated at 200V or more), or a linear (is there a large laminated-core transformer?). And what the main components, espeically ICs, are. -tony

PC Ephemera

I had a original IBM PC with the 64k motherboard and small power supply. A friend bought an XT as soon as they came out and it had the 256k motherboard. I don't think they ever made a 64k XT. Later I had my BIOS upgraded to install a 20 MB hard drive. (And a power supply upgrade.) I had to take my computer to an authorized IBM dealer to get the BIOS swapped. They would not just send you a ROM. Even with an AST 6 Pack I did not have 640kB or RAM because of the 64k motherboard. (But I did have a cassette interface.) Michael Holley

Chicago-area DECies?

by ISC277＠CLCILLINOIS.EDU

Hey, I was just wondering if any of my fellow DECies on this list live in the Chicago area, I know there were quite a few DEC shops around here back in the day.

It figures! (broken 9-track)

by ISC277＠CLCILLINOIS.EDU

Well, it figures. I was bragging on the list about how great my 9 track worked with the DQ132, and the power supply blows. I turn it on now, and no lights, nothing. Anyone have a clue what might have gone? I was away when it happened. The PDP11 was off, and I had left the 9 track on, plugged into the power control. The unit is an Overland OD3201. There is no external fuse. TIA Julian

Wolfe, Julian would like to recall the message, "It figures! (broken 9-track)".

chipset pinout wanted for 82C206.

by jpero＠sympatico.ca

Googled and can't find a datasheet. Seems the payware website had cleaned out the websites where you can access datasheets before. What I needed: typical schematic or description of CMOS battery back up 3.6V rechargeable with 4069 IC and 82C206 (SiS, UMC, OPTi and C & T uses this 82C206) specifically chipset's pin number for battery back up to retain data and run clock. I'm trying to troubleshoot typical motherboard that is not holding CMOS data even I do have 3.6V battery power (already checked). Cheers, Wizard

Comment on 'boardswapping' as part of the computer CULTURE.

by marvin＠rain.org

Board swaping and component replacement both have their place and that place depends on your particular philosophy and goals. For myself, I look at component replacement as a way actually learning how things work instead of shotgunning a problem until it appears to have been solved. Actually understanding how something works leads to progress while I *firmly* believe that the board swapping only mentality leads on a spiral path downwards. Board swapping is the obvious answer to the time problem of reducing downtime ... most of the time :). A good analagy that most of us have run into is the "my son/daughter/friend/??? is an expert with computers and can fix anything." Most of these people are called experts *only* because of they know a bit more than the person making the comment. Knowing how to reformat and reinstall an OS has its place, but without knowing what is going on, it is really easy to reinstall the same problems that generated the "Oh, you need to reformat the HD ..." And Tony's comment about "that's the way things are done ..." is a great statement that I fully believe in and support!!! A sad (to me anyway) commentary on people in the US are the number of people who prefer to buy an assembled and tested unit instead of building it themselves when given an option.

If you can prove that your repair business model would be more successful than the one that has evolved over time in the electronics industry then you should write a book and become a consultant and make millions.
