A card which is designed to be plugged into the CPU Fast slot of the A4000 or A3000. This card was generally shipped as the standard processor board for 030 based A4000's and usually contained either an 030 (with MMU) or EC030 (no MMU) running at 25Mhz. Commodore had originally also considered shipping A4000's with an 020 specification however this never happened and so any versions of this card (if there are any) containing an 020 are likely to be prototypes or from a demo machine. The A3200/A3400 printed on the PCB actually refers to the machine the card was to be installed in. Apparently Commodore actually considered calling the 020 based A4000's the A3200 and 030 based A4000's the A3400.
