centurye: Unterschied 103/103A; CRT Testivator

There were two models of the Testivator made, a Model 103 and Model 103A. The standard plain 103 didn't have a fixed 8-pin octal socket but instead the socket was on the end of a permanently attached cable and also the 2-pin AC connector was in an odd place (on top of the unit beneath the carrying handle).

On the second version (103A) the octal socket was mounted fixed to the chassis and instead a patch jumper connector cable was used to connect the unit to the CRT. Also the 2-pin AC connector is mounted out of the way on the right side of the unit so it looks like the 103A seems to be an improved/revised design of the 103.
