Many years ago I bought a AT102 Digital Lab by "A-Tek". It is a mains powered electronics breadboard laboratory using 0.5mm wire connectors. I have use it quite a bit, but there is no reasion why anyone could not build up there own version of a breadboarding lab.

POWER SUPPLY: a multi wound & tapped transfomer provides DC voltages to various regulators to give;- Fixed: +5V DC @ 2A max, & -5V DC @ 500mA max. A floating +5V for the DVM, Variable: 0 to +18V DC @ 800mA max, 0 to -18V DC @ 500mA max.

OSCILLATOR: 1Hz - 100kHz in 4 decade ranges. output:-
Square, & Ramp Outputs ñ5V. Sine output variable to ñ3V constant level with buffer amp. (added CR filters, to improve shape)


AF AMPLIFIER & LS: (added as room inside) High gain audio monitor amplifier & gain control with internal LS or 1W into 8ê 3.5mm output jack, 100k input Z.

LOGIC TOOLS:
4 logic level switches give 0 & 5V,
2 centre off logic level switches give -5, 0, +5V,
2 press buttons +5v or 0V pressed,
1 J-K Flip Flop gate,
8 data display LEDS with drivers, +5V for on,
2x 7 segment displays with drivers.

COMPONENT PATCH BREADBOARDS
Two 48 row component boards for 0.5mm wires etc.
For 0.4" DIL ICs, bus surround. & for 0.2" DIL ICs, bus surround.

EXTERNAL CONNECTION CONVERTERS
Four 4mm wander sockets to 0.5mm wire sockets.

3« DIGIT DC VOLT METER
Isolated meter, 10Mê Input.
Ranges 0-200mV, 0-2V, 0-20V, 0-200V.

USES
Plug in Rs, Cs, transistors, IC etc to make a test circuit up. I keep long lead components for use in it, & often make up actual circuits with short lead recovered components etc. Quite useful for AF responce checks & even some complex analoge & digital IC setup tests.
