I was going to say this earlier but is it the insides of one of our SMT machines ?

That's what I was thinking at first but couldn't get past the "reel" part.  But SMT machines do have reels of parts.

Reeeeel good of you to figure it out boB since you OWN it!!!! :)))) Doug gets demerits and or loss of atta boy points....:(

Don't have a pic of the Quad but here are some of it's Reels......



I got the deluxe kit, it had a solar cell and a meter.

a bank of power transistors on a heat spreader, that may attach to a heat sink underneath
not much visible in the way of IO connectors, 6 pin inline, and only 2 lugs for larger wires visible. Must be more ...
a couple big capacitors
3 big relays (where are their IO connections ? )
lots of discrete parts (transistors, chip resistors & chip caps)
Could be anything that handles some power and steering.

Ok, overhead shot of the board. On the left is the one in question from around 2017 if I'm reading the chip date codes correctly. The board on the right is an older version of it dated May 1994. Just a few minor changes....:)
