The Equity If has a power supply that is switchable

between 115 V, for US and Canadian use, and 230 V, for

use in other countries. The voltage switch is located at the

If you

When

installing a copy - protected software package

 

 

 

 

on the Equity I +, set the the CPU speed to

 

 

 

 

4.77MHz. This has been found to have fewer

conflicts with copy -protection. After the installation, the CPU can be switched back to the higher speed.

RS232C Serial port

WARNING! The voltage is not changed between the AC inlet and the AC outlet. If the CPU is switched for 230 V in order to function in Europe, only peripherals certified for use at 230 V should be plugged into the outlet.

-If a software package does not appear to be compatible with the Equity I+, try switching the CPU speed to 4.77MHz before giving up. Some software packages (e.g., Disk Optimizer from Softlogic Solutions) have been found to function only at 4.77MHz.

Video Adapters

-- - When using the Epson MGA video adapter in conjunction with a monochrome monitor with the Equity I+, set DIP switches 2- 1 and 2-2 both OFF. This will define the parallel port as secondary and avoid conflict with the address for a parallel port on the video adapter. The port itself is not installed on the adapter, but the address is in use.

-- - When using an EGA or VGA video adapter in the Equity I+, set DIP switches 1 -5 and 1 -6 both ON.

Installing Floppy Disk Drives

-When installing a floppy disk drive as drive B, remember to set the drive select jumper to the second position and attach the pass -through connector on the floppy drive controller cable to the drive, not the end connector.
