The Mailbox section of your
February issue, had a letter from
Mr. William S. Anthony of
Anthony Music Systems, Inc. He
questioned the fact that it was
possible to go into a crowded
room on a Saturday night at 6
p.m. to repair a solid state Bally
Evel Knievel pinball. Also, sta-
ting that if it was an electro-
mechanical game there would be
no problem.
In rebuttal to Mr. Anthony I
would like to make this very
simple comparison between an
electronic and an electro-me-
chanical flipper. I think I should
state first off that having started
in the era of the electro-mechani-
cal pin balls and having taught
many schools on electro-mechani-
cal pin balls when the electronics
were first introduced, I was
apprehensive of learning a whole
new state of technology until I
attended one 16 hour lecture
presented by our engineering
department.
At the end of the two days
worth of lecture, I came out with
a completely different idea and
frame of mind about solid state
flippers. I was still apprehensive
because I could not comprehend
that they were that easy.
Since then, I have found out
that they are. Today we teach
one or two day schools on
electronic pin balls and can teach
a person to be competent in the
repair of the machines. There is
no way that in one or two days,
starting from scratch, I could
teach somebody that much about
an electro-mechanical pinball and
I think the reason is and the
comparison that I wanted to
make is a simple one. One circuit
in electro-mechanical pinball is to
give points, activate an assem-
bly, light a line, and give points,
can encompass a large gamut of
switches, wires, relays and sole-
noids and within the game each
circuit is different, and from
game to game each circuit is
different, which to memorize the
circuits would be virtually impos-
sible. However, on the solid state
machine, each circuit within the
game is the same and from game
to game is the same which makes
it much easier to work on the
games.
The only thing that I can ask
Mr. Anthony to do is to attend a
school and see for himself.

Thanks a lot for your interest.

Technically concerned
In reference to the article,
Technical Topics by Randy
Fromm on page 47 or your
February 1978 issue , Mr. Fromm
states that a .22 microfarad
capacitor should be placed across
C-24 on the solenoid driver / volt-
age regulator module in B games.
I have two concerns for this
matter.
First off, my name is used in
his article which in no way
offends me, except for the fact
that the .22 microfarad capacitor
is an incorrect solution to the
problem he describes. The cor-
rect capacitor is described on
page 48 of the same issue. A .1
