The notebook pc is a Zenith running DOS 6.2 with a Q Basic keyer program by Cody Snider, KC6UNN. The black box on the left houses the Little Joe (one Watt) transmitter and a 100 Watt Solid State amplifier (gold color in center of black box)
The small white box on top of the transmitter is the keying interface, consisting of NPN switching transistor, 1K resistor and the LPT-1 connector and cable.
The amplifier is rarely used. Check this site for current configuration which will be listed on page one.
