Virden) Distribution: na Organization: N8EMR's Ham BBS (HBBS), Columbus,Ohio Lines: 42 Summary: 256k GS chips reminder I just want to post the standard reminder - Not all 256k chips are equal. The GS takes special memory refresh features (cas before ras?) and thus one cannot just plug any kind of 256k chip into your board. Likewise, there is at least one brand of the right refresh which doesn work just right - unfortunately I dont have that info with me right now. So, read the doc that comes with your GS memory card and use ONLY the brand chips it refers to . Tell MicroProcessors, INC that you have a brand X memory board for an Apple II gs and they can help you get the right chips. Sell the other chips to someother poor sucker... Antedote: I went into the local apple dealer to buy my memory card a few months ago. I asked for an Appl. Eng. GS ram card. The price was reasonable for a 256k card so I then asked how much the extra chips would be. This was BEFORE I knew about MPI. The price sounded good (it wasnt) so I asked for the dealer to put the chips in for me. Now I told them what kind of chips that I wanted, showed them the literature fromthe board etc. I KNEW that the wrong kind of chips wouldnt work. This is a big time, more than one store in a chain type place - with supposedly technically knowledgable folks doing the work. The salesman says "no problem, I do this all the time". So off he goes. I watch as the chips go on the board. I notice that the chips are NOT the kind approved by AE or Apple, etc. So I "innocently" ask, "Can we check out the board using this ram testing software before I take it home?" "Sure", says the saleman, "but it will be okay, I do this all the time." We set up the board in the store's GS and run the diagnostic, and ALL additional chips flag as bad! "Oh my", I say, "there must be something wrong." "No problem", the salesman says. "It is probably just one bad chip." So for two hours we replace a chip or two at a time, using the RIGHT kind of chips. Amazingly enough ;-) the board works fine when the salesman puts in the chips that I suggested that he use in the first place. Total time spent - more than 3 hours! He was going to send me off home to fight with this sucker by myself. Moral: DONT take hardware that the dealer 'enhances' out the door without verifying that it indeed works as you expect. -- Larry W.
