I currently have 1.25meg >(Apple Exp. Card), and wish to upgrade to a 4 meg board that uses 1 meg SIMMS. The GS Sauce is the only card I am aware of that takes 4 1 meg SIMMs. The OCTORAM will take 8 1 meg SIMMs, but I don't know where you can get those nowadays; someone else probably does. >So my questions are: /(DMA compatible, etc.) > Do I have any limitations on what "type" of memory I can use, due to > the use of: TransWarp GS (w/ DMA upgrade), Apple DMA SCSI card, and > an Audio Animator (not yet, but real soon)? TWGS w/DMA and Apple SCSI should get along fine. Audio Animator should work fine no matter what: it doesn't have anything to do with DMA. The only restrictions on the memory you pick are: 150 ns or better (preferably MUCH better) must be a four-row card (GS Sauce, many others that take DIPs) OR and eight-row card (OCTORAM) with 1 meg in each row (NOT 256k). I strongly advise you NOT to buy any GS memory boards from AE. Theirs are all DIP oriented, so that doesn't look like much of a problem. > What cards are out there that would suit my needs? The one I hear > talked about the most is the GS Sauce card. Will this work? Yes, this will work. I have one now, with two 1 meg SIMMs in it and it works just great. The meager instructions it comes with are somewhat confusing, and the configuration DIP switch needs to be modified somewhat, but overall I was impressed with it. I have had no compatibility problems whatsoever so far (1 week). This is to be expected; the GS Sauce follows Apple's RAM expansion guidelines to the letter. > I have no problem with buying a card bare and adding RAM on my own, > but specifically which chips will I need and where could I find > them.

Chip Merchant: 800 426-6375 (orders) 619 268-4774 (info) 619 268-0874 (FAX) 9541 Ridgehaven Ct., Suite A, San Diego, CA 92123 1 meg simms, 80 ns, are running about $50 each these days. >I have seen and heard about some pretty incredible RAM prices, and I just want >to make sure I don't get taken for a ride by buying cheap chips that won't >work. Chip Merchant is reliable. A friend of mine bought 4 megs from them for his Mac II and has been using them for a year without problems. Be warned, however, that the Chip Merchant DOES NOT TAKE CREDIT. They only accept COD and Prepaid. I was too impatient to prepay, and I couldn't arrange for someone to be home to pick up the COD, so I blew a little extra dough an bought my two megs from Fry's Electronics in Sunnyvale. They're having a sale this month (1 meg for $60, in a walk-in retail store) -- they always have a sale on something, whether it's clone motherboards, VCRs, or Coke.
