020/030 prototype CPU board
Hi Res version, Front
- 4608 x 3456, 3,146K
Hi Res version, Back
- 4608 x 3456, 3,805K

A combined '020/'030 card used to prototype the A2400/3400 (the 3400 eventually morphed into the A4000).  One of few cards that has both CPU's mounted. 


Production cards omitted the 68020 CPU and any unnecessary logic parts.

The A4000D requires an additional logic part (not installed on an empty solder pad) to use the 68020 CPU setting.

The 68001/68882 FPU socket can be separately clocked from the native CPU/Motherboard clock.

This board uses Int/Int clock settings from the motherboard.
