This subtest functions the same as Subtest 04, except it is used for testing an
optional memory card. Memory module capacity is 8 MB, 16 MB, 32 MB,
64 MB and 128 MB.

Subtest 06
Cache memory
To test the cache memory, a pass-through write-read comparison of '5A' data is
run repeatedly to the test area ('7000':'Program' size to '7000':'7FFF' (32 KB))
to check the hit-miss ratio (on/off status) for CPU cache memory. One test takes
three seconds.
