The first digit denotes the system. If all numbers after the first digit are zero it's the base computer itself. Thus A500, A1000, A2000, A3000. If non-zero digits follow, it's a peripheral intended to work with that system. Thus the 2620, 2320, 2332, and 2091 are intended for the A2000. The A501, A520, and A590 are intended to be used with A500. The A1010, A1070, and A1080 were originally intended for the A1000. Similar products are grouped under the middle two digits. The A108x's are all NSTC/PAL monitors. The A23xx's are, I beleive, network adapters. The A26xx's are accelerator boards for the A2000. When products they do not have a close association with a particular machine are introduced, precedence is used to determine the number. Thus, the A1011 and A1084 follwed the A1010 and A1080 even though the A1000 was out of production when they were introduced. Letters are appended to denote minor changes or bundles of existing products. Thus the 2090A, 1084S, A3000UX, A2000HD. There are some exceptions, of course. The 3000T is a different motherboard than the A3000 and is not a direct replacement. The A2002 monitor did not follow the precident of the A1080 (It didn't last very longer either). I don't know why the A1950 wasn't given a A108x designation. Eric Edwards: c506634 @ "I say we take off and nuke the entire site Inet: umcvmb.missouri.edu from orbit. It's the only way to be sure."
