Well, I doubt you'll be able to find much on this one. The lockout chip's
operation is defined in US Patent 4,799,635, however, all the related
schematics and code is property of Nintendo (and a well-guarded secret,
I believe, or at least at one time). My guess is you cut the trace which
is actually the reset line (explaining the non-functioning reset switch),
so maybe a good bet is finding some way to repair the trace (maybe conductive
pen would be a quick-fix to see if that resolves the issue).

If you cut traces in funny places, there's a good chance that it won't work
right, unless you can figure out where the traces you cut were going and fix
it with jumpers, and yeah, a schematic would make the task easier, but I
don't think there will be one to be had on this one. Best bet will be to
try probing everything with a multimeter, maybe comparing everything to a
"known good" console.

As for the technical details on this modification, cutting pin four and
shorting to ground will work (that won't disable the reset switch), so the
creative soldering shouldn't be necessary, but it still might take some work.

Fixing cut traces is a piece of cake, just scrape off some of the solder
mask or find an existing joint nearby on the correct trace and solder a
piece of wire wrap wire to join it.
