as far as i remember only the daystar "master" cpu was special and you could drop any cpu you want into the second slot? but dunno anymore if it was that way.
No, the master cpu would work if you dropped it in a 7500 or 8500 or 9500. The second cpu was the proprietary cpu. The two cpu's were attached by a ribbon cable. The cpu's could be mixed and matched. The main cpu could be a 233 MHz with a 46 MHz bus speed. The secondary cpu could be 200 MHz with a 50 MHz bus speed. The machine would then run at the speed of the slower processor. In this case 200 MHz with the 50 MHz bus speed.
