Minutiae:

Improve performance by installing a Newer Technology level-2 cache DIMM, part # 7CC512C.

APS M•Power 603e200 can take only 3.3 volt EDO DIMMs.  It does not support interleaved memory.  The three DIMM sockets are NOT identical.  The first socket, which comes stock with a 16 MB DIMM installed, can only accept up to 32 MB DIMMs.  The other two sockets can accept up to 64 MB DIMMs.  The maximum memory is therefore 160 MB.

APS M•Power 603e200 has a socketed CPU daughter card which can be upgraded. No specifics on upgrades or upgradability for APS M•Power 603e200 are available at this time.
