Heh. Typically, $300 - $500 on the rare occasions when they do show up on Ebay. I want one too...but not that much. I don't remember the exact URL, but google on Gamba SE/30 to get to a page with much discussion about this card. There are also a number of threads about it in the forums at 68kmla.net (68K Macintosh Liberation Army; rescuers of old, abandoned and unwanted 68K based Macintoshes). Some other discussion at applefritter.com's forums. The book the poster on the other related thread is probably thinking about is Larry Pina's "Macintosh Repair and Upgrade Secrets", which Tony probably disapproves of. :-) Pina discusses and recommends replacement of components based on the items which, in his experience, most often lead to certain symptoms. He does not discuss doing an actual probe and diagnosis to determine the failed component, which is why I good naturedly refer to Tony's disapproval. There are a couple of later variants on the above book, such as "Macintosh II Repair and Upgrade Secrets", "Mac Classic and SE: Repair and Upgrade Secrets", etc. These sometimes go for ridiculous sums on Ebay as well, but are often available at Amazon or other used book sites for very reasonable prices. At the moment "The Dead Mac Scrolls" are starting at over $100 on Amazon, but if the past is a guide, it will show up for under $20 if you wait around a while. Jeff Walther
