Sound
-----
The existing sound input is 8-bit linear PCM with analog limiting to
enhance the power of the signal being digitized. The sample rate may be
set for 22 kHz or 11 kHz. Therefore, the results will not be
significantly better than a low cost cassette recorder without noise
reduction. This level of performance is adequate for voice annotation,
but will not produce the best results with music.
Long Memory Checks
------------------
When you install large amounts of DRAM, the memory check at startup is
lengthy and you may think the machine isn't functioning. There is no
message saying that the machine is running memory checks.
Processor Cooling
-----------------
The Quadra 900 is designed with special cooling considerations for the
68040. For the processor to cool properly, the case must be closed
whenever the Quadra 900 is running.
