Cliff Hanger Pinout Part 2





This is not a complete list, but I will cover most features. Switch 4 is actually
dip #1 at location H-11. From there they go right down the line. Most boards
are silkscreened with the switch numbers already on them.

5 This group controls window or move time. All on = easy, off = hard

12 service mode = on + reset (S3 on CPU board = reset button)
13 switch test = on (test control panel & other switches)
14 freeplay yes = on
15 player immortality (player inputs are N/U in this mode) yes= on
16 disc test (this tests your disc and reports errors) yes = on
17 attract mode sound yes = on
18 & 31 both on = long scenes, off = short scenes (this cuts story)
19 buy-in/continuation yes = on

28 & 29 3 lives = off, off 6 lives = on, on

30 eliminate hanging scene = on (you'll want this on after 5 minutes)
32 display score & lives over animation yes = on
33 hints yes = on
34 & 35 "should have gone right/left, etc" never = off, off

Pots: there are 4 pots on the sound board. The one by itself at the top right
hand corner of the board controls screen brightness. The 3 at the bottom deal
with volume control.

Socketed ICs on CPU board:
There are 4 or 5 roms depending on which software you have. I don't think
there is any difference, except that you can use 2 different types of roms:
2732s or 2764s. J4 is a jumper on the CPU board that determines which
roms to use. Jumpering pins 1 & 2 will make it think that it is using 2764s.

Bookkeeping ram (E6) = TMS4016
Scratch ram (D6) = TMS 4016 (note the socket has 2 pins that are N/U)
CPU (E4) = Z80A

Socketed ICs on sound board:
A4, A5 = TMS4416
B5 = the impossible TMS-9128NL video processor chip that is required
to play the game. If anyone finds any of these or knows where they
can be found, please let me know.


The video outputs of the sound card go to the NTSC and overlay cards. I
don't have either one, as I am playing the game on my TV and using a
separate monitor for the onscreen hints and score. If you want to play the
game on your TV, all you need is the CPU and sound boards which is what I
have given the pinouts for. You will also need a Y cable to split the video so
that you can pipe it into your TV and the sound board. The game uses the
video input to read the disc so the sound board is required.

If you are just going to play the game on your TV then there is no need to
mess with J1 of the sound card. If you have a separate RGB monitor, you
can run the outputs of J1 to the RGB and run the video from the player to
your TV (and sound card) and you will get both. This method is not too bad
if you have a small RGB on your test bench.

To get the game to run on a RGB monitor you are going to have to find a
NTSC decoder card. The player's video output would go to the NTSC card
(and sound card, remember) and then the output of the NTSC card would go
to your RGB monitor.

To get the nice on-screen hints, you will need the overlay card. This card is
next to impossible to find but it is possible to make one.

By the way, the game flips around from running the demo, to the credit
screen, instructions, etc. so if you hook it up and your player sits there for 2
minutes on pause then don't freak.

Intial self-test procedure:
Upon turning the game on, the PCB goes through an initial self test. You
should here 8 consecutive beeps and see simultaneous LED flashes on the
CPU board about 1 second apart. The beeps correspond to the following:

1 = Z80
2 = Rom 0
3 = Rom 1
4 = Rom 2
5 = Rom 3
6 = Scratch ram
7 = Bookkeeping ram
8 = video ram test 4A & 5A on sound board

If any of the beeps hang then you have a problem.

One other thing, Cliff Hanger uses the PR-8210 player and I have heard that it can
also run on the LD-V1100 with an infrared transmitter (which only consists of two
diodes and two resistors).

OK, that should get you guys up and running. Have fun and long live Cliff
