The Apollo 4040 is designed to be plugged into the CPU Fast slot of the A4000 series machines as well as the A3000T. The Apollo 3040 is almost identical to the Apollo 4040 except it contains only two SIMM slots and is therefore better suited to fitting in a desktop A3000. The Apollo 3040 can still be used in A4000 series machines as well as the A3000T. Most versions of this card also contain a SCSI-II controller which is non-DMA but capable of transferring at up to 6MB/sec. The original 68040.library from Commodore cannot be used with this card, instead you must use the supplied library.

A4000/A4000T Installation

The motherboard jumpers marked CLK INT/EXT (or possibly CLK I/E) should be set to the INT (I) position, before installing the card. If the jumper is in the incorrect position, the machine will not boot.

A3000/A3000T Installation

For installation in an A3000 series machine, you must have at least Kickstart 2.04. You cannot use Kickstart V1.4, the pre-boot kickstart that loads the ROM from disk, regardless of the Kickstart version it eventually loads. NOTE: This card is reported not to work in versions of the A3000 shipped with an 030@16Mhz, although it may be possible to upgrade an oscillator on the motherboard to allow the card to work, this has not been confirmed.

CPUCLK (J104) Must be set to position INT on the motherboard
BRDCLK (J102) Must be set to position INT on the motherboard
QUADCLK (J100) Must be set to 25M on the motherboard.

For installation in an A3000 series machine you will require a chip adaptor which was usually supplied with the card. The SCSI chip on the motherboard and one of the Kickstart ROMs should be removed and inserted into the adaptor, wish is then placed into the empty sockets on the motherboard.

Note: Most SIMMs do not contain EDRAMS which are DRAMs with an 8K cache, however if you use EDRAMs you can gain a speed increase by using this Jumper. EDRAM is NOT the same thing as EDO RAM.
