A604, Memory Expansion (and more) for Amiga 600

This memory expansion card A604 for the A600 offers all the features that its predecessor A603 already had:

  •     1 MB additional Chip RAM (expanding the A600 to 2 MB Chip RAM)
  •     battery-backed clock
  •     Clockport for A1200 expansion modules (*)
  •     Expansion socket for Indivision ECS

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.

(*) Only clockport modules with a cable can be used, e.g. Delfina, 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 additional modules.

For operation of the real-time clock, a coin cell (type CR1220) is required
