Stopped at a new thrift in the area Friday and picked up several books (19) and one is titled The Hard Disk Technical Guide by Douglas T. Anderson PCS Publications March 1991. In it all list of various hard drives and their spec's but the best part is the listing of various controller cards and their jumper setting's (93 pages). There is lots of other good information in it and it's a total of 224 pages long and cost me a big 20 cents plus tax. This will help a lot in working with older cards when trying to get the right jumper settings. If anyone needs help with a card email me and I will see if it's listed in the book.
