Logic Switches
Eight SPDT logic switches SO to S7 are provided with outputs at the connector tie
points. These switches set a logic 1 to corresponding tie points when pushed up, and a
logic 0 when pulled back. The logic 1 output voltage is dependent upon the jumper
installed in the CMOS/TTL selector, being 12 volts in the CMOS position and 5 volts in
the TTL position.
Connectors
All functions are permanently tied to these three tie point connectors. Each tie point has
two solderless connection points.
Solderless Breadboard
The solderless breadboard, UBS-100 accommodates up to eight 14-pin DIP ICs with 4
tie points per pin plus 8 power rails with 25 tie points each.
