Q10.
What is the Auto Speed function?
A.
The Equity Ile is capable of operating at 12MHz or 8MHz. Some copy -
protected applications require the computer to run at 8MHz while
accessing the program diskette. By enabling the Auto speed function the
computer automatically switches to 8MHz when accessing the diskette
drive. It then switches back to 12MHz for optimal performance. Auto
speed is accessed through the SETUP program under the Auto speed
option.
Q11.
Does the Equity Ile use the Phoenix or Award ROM BIOS?
A.
No. All Equity computers utilize a Seiko - Epson proprietary ROM BIOS.
Q12.
Does the Equity Ile have a battery for the Real Time Clock?
A.
The Equity Ile is using a "Dallas" model DS1287 which incorporates an
HD146818 compatible real-time clock with an internal battery.
Q13.
How many wait states does the Equity Ile have?
A.
At 12MHz 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
I/O expansion bus, 16 - bit memory or device requests require 1 wait
state while 8 bit memory or device requests require 4 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.
Q14,
How many jumpers are on the system board?
A.
There are three (3) jumpers on the system board:
Jumper 1: Password Enable/Disable
Jumper 2: P - ROM type
Jumper 3: IRQ12 Assignment
A: Enable (Default)
B: Disable
A: 256KBit (Default)
B: 128KBit
A: IRQ12 dedicated to the auxiliary mouse port. (Default)
B: IRQ12 available to devices on the I/O channel.
