Memory Expansion (and more) for Amiga 600
+++ No longer available, replaced by
The new memory expansion card A604 for the A600 offers all
the features that its predecessor
- 1 MB additional Chip RAM (expanding the A600 to 2 MB Chip RAM)
- battery-backed clock
- Clockports for A1200 expansion modules (*)
- Expansion socket for
The A604's new design allows to mount an Indivision ECS without losing the
floppy disk drive (which was a problem with the A603 card). Additionally, the
A604 now features a second clockport especially designed for the
Subway USB controller module.
This second clockport can boast a performance gain of 60% compared to a
standard clockport, so the Subway's USB transfers are faster than ever before.
A604 with Riser Card
Please note the screw that secures both the floppy drive and the riser card.
This solution offers maximum stability for the Subway controller.
A604 on Trapdoor Cover
The A604 was designed and manufactured with extreme precision, hence the
accuracy of fit as seen in this picture.
A604 with Subway
The Subway controller is mounted on the riser card like shown in
this picture, definitely more stable and clean
than the original cable solution.
A604 with Subway and Indivision
...is not the maxed out configuration yet, you could still
add another clockport module(*). :-)
(*) Only clockport modules with a cable can be used, e.g.
Catweasel Mk2, or
Silversurfer Limited Edition.
When using the second clockport, modifications to the metal shield may be
required (if the shield is present at all).
The A604 can be installed through the trapdoor bay on the bottom without opening the case.
However, it is recommended (and may be required) to open the case when installing
For operation of the real-time clock, a coin cell (type CR1220) is required, which
is not included (but can be ordered separately).
