Pins 8-11
are control lines A-D. They are for interfacing to our
or other microcontrollers. On
these pins are connected to the
main CPU.
Pins 2-5
are I/O lines facing the outside world. On Tibbo Project PCBs they go to
Tibbit
(i.e. connect to
Pins 6 and 12
are the GROUND and +5V power pins. Most Tibbit Modules consume
(take) 5V power. There are also power supply Tibbits that generate 5V power from
a variety of sources. Those
output
5V through pin 12. As an example of power
Tibbits see Tibbits
Pins 1 and 7
are for the addi15V and -15V voltages. These are optional and
only needed by few Tibbits. A special power supply Tibbit
