Q15.

How many internal device bays does the Equity 386SX have and will

it support a full - height device?

The Equity 386SX has 3 half - height bays to support up to 3 half -

height devices. The separator between bays 2 & 3 can be removed

to allow for the installation of a full - height device.

Q16.

How many wait states does the Equity 386SX have?

At 16MHz the system utilizes a "1/4 wait state" architecture for

memory access and 0 wait states for ROM BIOS access on the

motherboard. At 8MHz, memory and ROM BIOS access require 1

wait state; on the expansion bus, all memory or device requests are

1 wait state. If additional wait states are required, devices on the

I/O channel hold the READY signal low thus wait states are

generated until the device can respond to the CPU.

Q17.

Are the wait states user selectable?

No, the Equity 386SX automatically inserts them when needed after

the command phase of the processor clock cycle.
