(PART 4)
BY EDWARD J. SCHMIDT
Field tests on "Moon
Shuttle" indicate that while the
game is getting good play, the
length of play per quarter is
becoming unacceptable at
some locations.
In line with Taito's contin-
uing policy of providing the
best service possible, they are
rushing new roms to cover
"Moon Shuttle" games already
delivered to your distributor.
Questions For Evaluating New Technicians
16.
How would you read a voltage of 250 VDC with a VOM?
(Where would yo place leads and scale settings?) Please describe.
17.
What is an integrated circuit?
18.
There are three (3) basic Transistor Amplifiers; they are C-Base,
C-Emitter, C-Collector. Which one provides signal Inversion?
A. CE
B. CC
C. CB
19.
Describe briefly the operation of schematic below.

Le
effect of these new
roms is to increase the
difficulty from the first frame
and make the game increas-
ingly difficult as the player
continues.
The
new rom will, of
course, be in Taito's
production run.
Taito believes that this rom
change will not only heighten
player enjoyment, but will also
boost earnings significantly.
Contact your distributor for
further details and
availability.
Note: The output of the Decoder is Active Low.
20.
Digital !C's are basic switching circuits which respond to:
A. Only at + 3 and zero volt levels.
B. An alternating DC or PDC voltage.
C. High and low logic levels.
D. Voltages that are between zero and + 3 volts.
E. None of the above.

ANSWERS
(PART
3)
11. A equals 0, B equals 1
12. A programmable read only memory is similar to ROM,
except it is manufactured as a blank without any data
stored in it. Each data bit is represented by a small fuse.
It is possible to "blow" the Prom at a later date with
proper voltages on the data lines and permanently
destroy the fuse in order for a bit to be represented.
13. A read-only memory containing data permanently
stored when the unit was made.
14. A random-access memory where words may be
"written" (stored) or "read" (recovered) in any order
at random.
15. C. Infinity
