Proms, CPU and video boards.
2. The sound and 1/ 0 board Proms are not affected by the name change.
3. Repeat; check for proper Proms in "Kick" and "Kickman".

Capacitor CP34 on Sound l/O Board (A082-90908-GOOO)
1. Capacitor CP34 on the Sound l/O Board has been inserted with polarity
reversed due to incorrect labeling on the P.C. Board. This can cause a loss of
+5 VDC when CP34 finally breaks down.
2. Remove capacitor CP34 or reverse its polarity on the Sound l/O Board.
Game:

"MOUSE TRAP" AUDIO BOARD MODIFICATION
The "Mouse Trap" Audio Board utilizes a Z-80 microprocessor. To insure
proper operation of the Audio Board, the following modification should be made:
1. Solder a 470-ohm resistor to PIN 1 of the 74LS74 at position C-1.
2. Solder the other end of the resistor to PIN 6 of the same 74LS74 at position C-1
This pull-up modification results in a better clock signal for the Z-80 and if not
done can cause some Zilog Z-80 microprocessors ( especially those with a date
code of 8152) to malfunction.
