How many internal device bays does the Equity 386/25 PLUS have and
will it support a full-height device?
The Equity 386/25 PLUS has 2 half-height bays to support up to 2 half-
height devices. There is no room for a full-height device.
How many wait states does the Equity 386/25 PLUS have?
At 25MHz the system utilities a "0 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 0 wait states: on the
expansion bus, all memory or device requests are 0 wait states. 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.
Are the wait states user selectable?
No, the Equity 386/25 PLUS automatically inserts them when needed after
the command phase Of the processor clock cycle.
