Fawn Dungeon Prototype

Ward Shrake dumped the prototype of Fawn Dungeon. He needed to repair a leg on the EPROM to get a proper dump. These are pictures of the repair in progress. Here is his edited original posting to the Astrocade discussion group about this subject. I edited the posting so that all of it is pertinent to the pictures:

I then did a fairly straight-forward-but-somewhat-advanced repair: in
essence, I made a new leg to replace one that was missing. A section of
26 gauge, single-strand wire was partially stripped; then partially
tinned. I bent it around the chip, so that the tinned section was near
the area I wanted it to be attached to: with the rest of the wire just
there because it's a heck of a lot easier to control the repair work if
you can get your fingers around a part, instead of using tweezers. I
put the work in a third-hand holding device (with the alligator clips
holding the excess wire onto the chip, reasonably tightly). I used a
small screwdriver to apply gentle pressure to another portion of the
wire that wasn't in my way; and then heated the two parts for a few
seconds, using a temperature-controlled Weller soldering station.

I sort of wicked most of the excess solder along the wire and away from
the important repair area; then let it cool down for a few minutes.
(Sort of like a kid wiping his nose on his sleeve; except with solder.)
The final step was to carefully cut the wire down to its final length,
using some sharp wire strippers that also work like strong scissors.
