8 Bit I/O Recovery Time
The recovery time is the length of time, measured in CPU clocks,
which the system will delay after the completion of an input/output request.
This delay takes place because the CPU is operating so much faster than the
input/output bus that the CPU must be delayed to allow for the completion
of the I/O.
This items allows you to determine the recovery time allowed for 8 bit
I/O. Choices are from NA, 1 to 8 CPU clocks.
16 Bit I/O Recovery Time
This items allows you to determine the recovery time allowed for 16
bit I/O. Choices are from NA, 1 to 4 CPU clocks.
Memory Hole At 15M-16M

space below 16 MB.
