>Whoa, the schematics should really be cleaned up! :-)
Actually, I would go with getting my Space Race paperwork (General instructions and troubleshooting pages) scanned asap and uploaded to various sites even though I will guess Space Race / Asteroid pcbs aren't being repaired as much these days.
Your schematics drawing bugs should be documented in the driver file and also mentioned on Discrete Logistics or any other sites that could make use of your findings.
btw: I noticed a couple of odd differences between Asteroid General Instructions versus Asteroid logic schematics. And it looks as though the hand drawn Space Race blue print sheets have 566 being used instead of NE 555, but that was probably before Space Race pcbs were in full production and placed into Space Race cabs.

General Instructions pages, in trouble shooting section have:
E-5 is 9316
D-5 is 7404
Midway Asteroid has a "D-?" indicated and I can't tell what number it is because it is in a folded part in which numer isn't readable.
On the hand drawn Space Race blue print sheet, it looks as if someone wrote over in pencil with "D" so as to prevent any confusion.
