FS on AuctionWeb: Apple, Atari, Commodore

by gmast＠polymail.cpunix.calpoly.edu

I apologize for the intrusion but I just bought a lot of Apple service parts for older apples (IIe, IIc, IIGS) and listed some of the ones I don't need on the auction. They were supposedly in stock at a service facility when they cleaned out the old stuff. I'mm still intending on clearing out most of my stuff but I couldn't pass up a good deal. I did get some parts for my laserwriter, Mac plus, a couple new in box 400k drives. Too bad I had to buy 30 boxes to get the 5 things I wanted. ;-) There are also some systems listed. Here's what I have listed there as of today: Apple IIe Power Supply (new in box!)

apple II - SCORE!

by thedm＠sunflower.com

I use alcohol, windex, fingernail paint remover and other noxious things to clean apple][ cases, just avoid getting the nastiest of these solvents on things like the little lite that says power, or the apple ][ logos on monitors or the name badge at the top of the machine. I've also heard that some people will dissasemble the computer leaving the empty shell, take out EVERYTHING, and run the plastic case through the dishwasher, not using the Heated drying cycle of course. As for key repair, they are little plastic wedges that are shoved against two vertically mounted contacts, counter forced by a small spring. You can not remove the keys without damage. To repair a keyboard you have two options, One, Replace the entire keyboard, or aquire a ][ for parts and remove the keyboard from the unit, the contacts are soldered into the keyboard cirucuit board. You can then replace the switch. The Key caps can be removed. but you can't get to the switch of course without destroying it, or desoldering it as a unit. I have manually recontructed them before, but they never seem to work quite right once forced open, but the do function enough to use as long as it's not an alpha charcter, or god forbid the enter key. ---------- > From: J.

Apple ][ design (was: Bad feelings)

by BROBSTONA＠wartburg.edu

>I can understand why the Apple ][ has a significant following - it was a >machine that was 'open', that hackers could get inside, etc. But I also >know that it's not a good piece of hardware design, and thus don't put it >high up my list of interesting machines. Perhaps I am merely biased from growing up with the Apple ][ at school and, later, at home, but I would say that some of the design is ingenious. I do know that many a programmer has complained about the arrangement of the high-resolution screen in memory (which was arranged the way it is to save components). But, I find the economy of this feature fascinating. The Apple ][ and its successors had great capabilities for expansion (with the possible exception of the IIc and IIc+). A IIe has the capability of using a hand-held scanner, for instance, with the right slot card and the right software. I'm sure the IIe wasn't designed originally for that task. There are numerous other examples as well. Your mileage may vary, of course. -- Andy Brobston brobstona(a)wartburg.edu ***NEW URL BELOW*** http://www.wartburg.edu/people/docs/personalPages/BrobstonA/home.html My opinions do not necessarily reflect the opinions of Wartburg College as a whole.
