Epson Equity II - Manual (Page 33)

Selecting an Execution Speed
The Equity II can operate at two different execution speeds. You
choose between a 4.77 or a 7.16 MHz clockrate. At the faster speed, the
Equity II performs all tasks more rapidly. You can select the slower execu-
tion speed to run application programs that have specific timing require-
ments.
To select the execution speed you want the computer to start up in,
use the MS-DOS SETUP program. To change between the two speeds
while the computer is running, you can use the MS-DOS SPEED com-
mand or you can hold down
Ctrl
and
Alt
and press 1. See your MS-
DOS manual for more information,
When the computer is running at the faster speed, the power LED
lamp in the top right corner of the front panel is green. At the slower
speed, it is red.
You can change the wait state when the computer is running at the
slower rate to further control the speed. The wait state can be any num-
ber from 0 through 7. The smaller the number you select, the faster the
Equity II runs. To set the wait state, you can use the MS-DOS SETUP
program or hold down
Ctrl
and
Alt
and press a number key from 0
through 7 on the main keyboard. For example, hold down
Ctrl
and
Alt
and press 3 to set the wait state at 3.
Resetting the Computer
You can reset your computer to load a different operating system or
reload the current operating system. For example, if an error occurs and
the computer does not respond to your keyboard commands, you can
reset the computer and try the same operation again. However, resetting
erases all data in the computer’s temporary memory (RAM), so reset
your computer only as a last resort.
In MS-DOS, you can hold down
Ctrl
and press C to stop a pro-
gram’s operation and return to the MS-DOS command prompt. If an
error occurs, try this method before you reset the computer.
WARNING: Do not reset the computer to exit a program unless you
have to. Some application programs classify and store new
data whenever you exit the program properly. If you reset
the computer while such a program is running, you may
lose data.
