MODIFICATION
You may make your 2716 adapter cards go
twice as far with this modification that al-
lows 2732 Proms to be used.
PROBLEM
Early model Drew's Tiger Paw Cranes were
fitted with Cherry limit switches with alumi-
num actuators.
PROCEDURE
First cut the traces from pins 20 and 21 of
the socket on the adapter card. Then tie pin
20 to ground (pin 13). Next run a wire from
the circuit that was going to pin 20 to pin 21.
Now combine the program that was on the
two 2716's to one 2732. ( Ul 1 is prom select
0) and install it on the adapter. The adapter
will then be put in the socket at U 11 with
socket at U 12 being empty. Now you adapter
cards will farther since only one will now be
needed per board.
SOLUTION
Because of breakage we are now using Mi-
croswitch limit switches with spring steel
actuators. These actuators bend and return
to the original shape. These switches can be
used in all six positions in the Drew's Tiger
Paw Crane. Part number 168V3L5608D8 at
a cost of $4.10.
NOTE
What this does is tie chip select on the 2732
to ground and allows the chip selects for the
two 93 l 6's be used as address line 11 on the
2732. If you need further advice or have any
questions, contact me at 615/764-8383.

Every route person should be carrying a
small dust brush so that when they go out on
a call, they can quickly clean the fan and air
vents on most games. Remember with Sega
and Atari's complex boards, over heating
can be a costly repair bill!
