[Jan/14/97]

These ROM images came from a working Naughty Boy boardset, and were verified
twice.

This boardset was licensed by Cinematronics from JALECO, and is also used in
Jack the Giant Killer and ZZYYZZYYXX, all circa 1982.

This boardset consists of 2 8 1/2" x 12" boards joined by 2 50-pin cables.  One
was marked NB-8201, the other NB-8202.  There is also what appears to be a
serial number written in magic marker: NB-00-00401.

Board NB-8201 has the Z80, an 8-pos DIP SW, a TMS3615-25, and 8 2716 EPROMS
labelled 1 (IC30) to 8 (IC23).

Pins 1 and 5 of the DIP SW were off.  This board also has a 36-pin edge
connector.  Pin 6 is missing, and is cut as a key.  A wire from where the
volume control could be placed runs from a pin marked VR1 to pin 8.  Another
wire on the bottom of this board runs from the pin counterclockwise from VR1
to the edge connector pad on the other side of pin 8 (the first and last pins
on this side are labelled A and V, but I don't know how the middle ones are
labelled).

There are 35 other ICs on this board, mostly 74LS logic.  IC20 has been sanded
to obscure the part number, but it looks like a TI SN74LS153N.  It is a 16-pin
DIP.

This board would seem to have the audio section (like Galaxian, no specialized
chip, just 556, 4066 and amps).

Board NB-8202 also contains 8 2716 EPROMs, labelled 9 (IC50) to 16 (IC43),
along with a crystal (frequency side down) and 59 other ICs, mostly 74LS stuff.
There are 2 socketed chips, Harris M3-7611-5.  IC63 has a red label with a 
U on it, and IC64 has a blue label with an L on it.  IC11 has also been sanded;
it is a 16-pin Hitachi IC.
