While cleaning out the boxs of Apple/Macintosh hardware software I have I came accross a DayStar digital CPU or at least That what I think it is. It has a number on it 01-00489 turbo 040 on the backside on the back it says DayStar digital, inc copyright 1993 and it has a newbus connector. It does have a Motorola CPU on it with a heat sink. Is it a upgrade CPU for an early mac or just dumpester material??
