Quoted from SantaEatsCheese:My only horror story is the tale of the 2 broken pinbots.
In case you weren't aware of the story continuation, your buyer gave up on them too, and passed them on to me!
I've had some unrelated stuff to deal with since then, but once the collection is back in order, the better machine is getting a reworked original CPU and a swap for the other machine's nicer backbox. Industry peers are telling me the junker isn't economically feasible to bring back, so its standard constituent parts will supply the whitewood for a homebrew.
