EQUITY III+ CPU SPEED SELECTION ENHANCEMENT

ENHANCEMENT DESCRIPTION:

The Equity III+ computer has been enhanced to allow the

selection of CPU speeds while the computer is in operation.

In earlier units,

changing the CPU speed while the system was

in operation was not recommended because it could cause the

applications program to misexecute.

An information sheet describing the change is being included
with the new Equity III+ systems to inform the user to
disregard the warnings against changing the CPU speed during
operation as stated in the user documentation supplied with

the computer.

Equity III+ systems with the following serial numbers have
the enhanced capability.

From

024515

024799

026770

027100
