Page 5Installation Instructions: Roadrunner 030 & 040 AM-1000 / AM-1200 Upgrade
The power supply in AM-1000 and AM-1200 computers will support one hard disk drive
and one diskette drive or one streaming tape drive; there is not sufficient power to
support more than two internally mounted peripherals. For the Roadrunner hardware to
function properly in your computer, your power supplies +5v DC voltage output must be
a minimum of 4.90 volts. The voltage output should be measured at the J3, J4, J5, or J6
peripheral power distribution connectors. Make the measurement at the AM-167 or
AM-177 board, not at the peripheral end of the DC power cables.
