Published in Sinclair Projects Aug. and Dec. 1983.
Built Summer 1983.
Size - 9" * 4 1/2" * 3".
Operational area - 3ft * 3ft plus host computer.
The B/W photos were taken in the mid 80s.
The heading photo was taken in 1999 and the Gallery photos in 2021.
Prowler's electronics run from 5v supplied over the control umbilical,
the interface is in the Gallery.
Some time in the 90s I added the 4AA cell holder with a switch at the rear
