I'm trying to help a friend repair an old 80's "Fun Chicken" vending
machine. If you are curious what this looks like, check out the

Well I'm not sure what happend to this poor machine, but a bunch of the
components on the main circuit board are toast. I need to identify four
of these. Here is a pic of the board with the component locations:

Any chance someone out there has one of these machines and could verify
these? A copy of the schematic would be even better!

I've been looking everywhere and so far no luck. Thanks a ton to anyone
who can help!

Hey I remember those! I haven't seen one of them in years though. What
exactly is the board supposed to do? It might be possible to make an
educated guess as to what the parts are, at least there aren't any
custom programmed microcontrollers or anything like that.

The part on the bottom-right looks like it might be a 3 terminal voltage
regulator, looking at how it connects to the rectifier diodes and main
filter cap will confirm or deny that. The one on the upper-left looks
like a power transistor, does the board drive a solenoid or motor?
