An option card must meet certain power supply requirements.
The option card cannot draw more than the specified current
(Amps):
+ 12 Volts 0.1 Amps
-5 Volts 0.05 Amps
-12 Volts 0.05 Amps
The option card must not interfere with options installed in the
internal ports. For example, if you install an option card with a
parallel port, you
must
assign that port as the secondary parallel
port (278H) if the internal parallel port is the primary parallel
port (378H). If you want the parallel port on the option card
to be the primary parallel port, you must define the internal
parallel port as the secondary parallel port by setting DIP
switch 5 to OFF. See ‘Setting the DIP Switches” in Appendix A
for details.
