Got it locally. It's an EM 4 drum fruit machine.
It was made in the UK in the mid to late 70's.
It's an ACE 3000. The base (not in
pictures) is pretty
much destroyed so I have to rebuild one. This is where the coins
go into. This machine does not have a hopper (it doesn't pay out
coins). It just accumulates credits. There's a small hidden
reset swicth that clears all the credits once they have been paid out.
Works well.. Needs a good cleaning and a few bulbs. Looking
for schematics.
