Could someone post the pin assignments of a 68k (68 pin grid array) I have a net list of am Amiga accelerator, but it lists the 68 pin chip, and I have a 64 pin chip.

For the record: Motorola Semiconductor Literature Distribution Center P.O. Box 20912, Phoenix Arizona 85036 (602) 994-6561 or for the academic world: Motorola University Support Program MD 56-102 P.O Box 52073, Phoenix Arizona 85072 (602) 952-3855 or call one of the 60 domestic semiconductor sales offices or call the Motorola Design Line (800) 521-6274 There is no good reason not to have the right documentation. -- Regards, Jim Reinhart Motorola Microprocessor Products Group Austin, Texas
