You mean IR "emitters"? (IR LED)
If i understand you correctly, you wish to source current with the
digital outputs. The digouts are from the HC11. There can't source enough
current to light IR LED's.

I want to be able to run 2 or 3 IR xmitters from the single output on the
HB with no additional hardware.

Is there any problem with hooking two or 3 IR transmitters to the ground
of the IR output and running the +5v from digital outputs.  Then switch
thru each one using the digital output. Only having one active at any
given moment.

What you can do is just like the schematic for the built-in IR emitter circuit. You need to either software generate your wave or do it like the schematic. If software generated, this output would come from a output port on the HC11 to a transistor (...) (27 years ago, 9-Apr-97, to lugnet.robotics.handyboard)
