major difference in the new cabinet
is that the coin box is not accessible
through the back of the game as it
was in the old cabinet. (The only
way to get to the coin box is through
the coin door.)

CONVERSIONS
Now fora II of you who are interested
in converting your Dragon's Lair to
a Space Ace, there are two ways of
doing this:
1 . You can convert from Dragon's
Lair to Space Ace without exchang-
ing the players.
2. You can convert from Dragon's
Lair to Space Ace and exchange
your old PR-7820 disc player for a
new LD-V1000 unit.
Now there has been a lot of
politicking going on between the
distributors to sell kits. I personally
know of one distributor who was
advertising and selling the kit with-
out the disc player exchange for
$150.00 below cost, but was
marking up the kit with a disc player
$300.00 above what others were
because he knew that he could
convince the people to exchange
the playerto"reduce maintenance"
so shop before you buy!

8. Reset signal sent from U23, pin
9to U16, pin 1 to cure false coin
count on power up.
9. Reference letter not used.

7. C63: Was0.001 ufdisc. Became
470pf effective 9/5/83.
When you convert your Dragon's
Lair to Space Ace you will receive a
videodisc, decals, marquee, control
panel, circuit panel assembly, 16-
pin ribbon cable, adaptor harness,
control panel harness, Space Ace
ROM set, some screws and a
manual.
In the LD-V1000 conversion kit
you receive instructions for remov-
ing the PR-7820 disc player,
mounting the LD-V1000 disc player,
modifying the wiring harness, and
exchanging the P.C.A. logic board.
In the LD-V1000 conversion kit
you will also receive a complete
parts list, instruction manual and
65 component parts including the
LD-V1000 disc player.
NOTES:
The major difference between the
Dragon's Lair cabinet and the new
Space Ace dedicated cabinet is
that the area where the disc player
sits is partitioned off in the new
cabinet. This helps to keep heat
out of the disc player area. Another

11 . C63: Was 470pf disc; became
330pf disc.
C17: Was 330pf mica; became
330pf disc.
1. Original release.
Addition of U31 (74LS74) to
divide clock.
2. R3: Was 1 K; became 300.
DO on U20 incorrectly shown
as pin 8. Changed to pin 18 on

16.000MHz.
U24: Was 74LS04; became
74S04.
3. Addition of capacitor C63, 220pf
disc between U24, pin 3 and
ground. 6/27/83.
Addition of R29 between U29,
pin 4 and C24.
Addition of R50 between U30
pin 4 and C50.

these were formerly a spare
gate. 6/29/83.
5. C40, 0.01 disc tied between
U22, pin 2 and ground is deleted.
7 4LS244 inserted between 01
collector and U22, pins 1 and 2.
U17, pins 11 and 9 used-these
were formerly a spare gate.
