Global Specialities is pleased to introduce a new ADVANCED state of the art proto-board design workstation which is ideal for higher level analog, digital and microprocessor circuit designs.

An exceptional combination of advanced functions, features plus exceptional performance, workmanship and flexibility of circuit design makes the NEW MODEL PB-505, (part number 104-1505) LIST PRICE $475.00 a valuable cost effective product for design engineers, educational institutions and hobbyists.

This advanced design workstation feature life-time guarantee on all breadboarding sockets and 3 year warranty on all parts and workmanship.

The new PB-505 features a larger removable breadboard area (3360 uncommitted tie points) and optional additional breadboard socket plates (part number 325-1448, List Price $63.75 each.)

This new model also features eight high (red) and low (green) buffered logic LED indicators, eight individual selectable logic switches offer-ing settings of plus, negative and uncommitted, a built in logic probe with pulse capture, a built in multi-function, multi-wave 100KHz, function generator with continuously variable sine, square and triangle wave forms and TTL pulse.

Besides the standard triple output power supply (2 variable and 1 fixed), two digital pulsers, audio experimentation speaker, SPDT switches, potentiometers and debounced pushbutton switches, This new advanced trainer also features a BCD to 7 segment decoder/display, special AC voltage output 12, 6 AC, center tapped at 6.3VAC, larger individual breadboard socket areas and is housed in a rugged metal enclosure.
