インテレビジョン用のジョイスティックを増設したい




デパートのデモ機で、ちょろっと野球ゲーム程度を遊んだかすかな記憶では思い出せない
改めて使ってみてわかるインテレビジョンのコントローラーの使いにくさ

何が駄目って四方向移動が基本のゲームではお話にならなかった

デコのマイナーアケゲー、LOCK'N'CHASE
デコのメジャーアケゲー、BURGER TIME

曲がりたいのに曲がれなかったり、下りたくないのに下ったり Oh! No!

インテレビジョン同様コントローラーの糞っぷりには定評のあるコレコビジョン
以前、そのコレコビジョン用には制限(テンキーほぼシカト)ありながらも
専用のコントローラを作ったことがあるのだが
インテレビジョン用にはそこまでする価値がない様に思えるのと種種の問題が

種種の問題
・テンキー必須のゲームが多すぎる
・乗っ取り不可の薄々シート
・へんてこマトリクス構造

ぶっちゃけインテレビジョンで遊びたいゲームは
アーケードの移植作品とACTIVISION,一部のIMAGICゲームのみ
その辺のゲームはだいたいスタート操作以外にテンキーは使わない
だからテンキーはコレコビジョン同様、無視しちゃっていいと思うんだ
そもそもそこまでソフトを揃えるかどうかもわからないからね

乗っ取りも楽だけどコントローラを潰さないといけないから
やっぱりこれも初めからなかったと思っていいのかな
↓の問題も関わってくるし

で、一番の問題が方向入力の問題
16方向とかどれだけ採用しているソフトがあるのか不明な操作系
マトリクスを1方向2接点のレバーにどう反映させたらいいもんだか
自分は機械的単純な方法でしか対応できないぞ
で、斜めはどうすればいいんだ?

とりあえず資料集め

Intellivision FAQ 内に丁度いい記載があった

7.5 - Pinouts for INTV Controller

The pinouts and information listed below are courtesy of Steve Roode, who in a fit of boredom decided to find out what happened when he pushed the 5 key on his Intellivision keypad...

In trying to build the ultimate Intellivision Controller, I thought that the hard part would be trying to figure out all of the pin assignment combinations for all of the buttons on the controller. It turns out I was wrong! That was the easy part... The hard part is finding components to make the controller with! I went to a couple of stores to look for a rugged, phone style type keypad, nice metal stick, and a couple of rugged arcade style fire buttons. Couldn't find any of them!

Oh well.... Maybe you can! The following will describe all of the pinouts combinations for all of the buttons on an Intellivision Controller (NOTE: I only spent time to figure 8 directions out on the disc. I figured it would be almost impossible to find a 16 direction joystick, and most games don't require that many directions anyway).

DISCLAIMER!!!!!

Hey, I'm just an average guy... I'm only doing this to help people on their way to building an Intellivision Controller that won't drive you nuts. I WILL NOT accept any responsibility for what these instructions will do to your Intellivision. I've tried it on mine, and it works fine. But please don't blame me for ANY problems these plans may cause. Experiment at your own risk!

OK, now that that's out of the way... Down to business!

I used a Sears Intellivision Controller since I had an extra one and it was removable from the system. Remove the screws on the back of the controller and open it up. Next, remove the disc, the side buttons and keypad. What you should see in the controller is a terminal where the cable comes into the unit. It should look something like this (The numbers aren't really there; they are my own numbering system):

Each pin on the terminal connects to a wire which connects into the Intellivision. The numbers DO NOT correspond to the connector pin numbers; They are my own numbering scheme. However, with a little effort, the interested experimenter can map them if desired.

OK, using the numbering scheme above I was able to figure out the pin combinations for each button on the controller. This took a lot of time tracing out the circuit on the plastic keypad, and verifying it with a Baseball cartridge plugged in! The following pins must be connected for each of the corresponding controller operations:

Connecting Pins Makes the Controller Perform
=============== =============================
1 and 4 Up Disc
1 and 2 Down Disc
1 and 5 Left Disc
1 and 3 Right Disc
1, 3, and 4 Diagonal Up/Right Disc
1, 2, 3 and 9 Diagonal Down/Right Disc
1, 2, and 5 Diagonal Down/Left Disc
1, 4, 5 and 9 Diagonal Up/Left Disc

1, 6, and 8 Upper Left and Upper Right Side Button
(SAME!)
1, 7, and 8 Lower Left Side Button
1, 6, and 7 Lower Right Side Button

1, 2, and 6 Keypad 1
1, 2, and 7 Keypad 2
1, 2, and 8 Keypad 3
1, 3, and 6 Keypad 4
1, 3, and 7 Keypad 5
1, 3, and 8 Keypad 6
1, 4, and 6 Keypad 7
1, 4, and 7 Keypad 8
1, 4, and 8 Keypad 9
1, 5, and 6 Keypad CLEAR
1, 5, and 7 Keypad 0
1, 5, and 8 Keypad ENTER

Whew! As you can see, pin 1 connects to every combination, so in building your controller it may be easier to connect this pin to a common strip and connect all controls to this strip.

In examining this circuit, you can see why pressing 1 and 9 at the same time is just as effective as pushing 3 and 7 if you want to pause a game. It connects the same pins either way (Pins 1, 2, 4, 6, and 8); You could even build a separate PAUSE button on your controller if you desire!

Many interesting features could be built into this controller. For example, if you are familiar with a 555 Timer IC, you could build an adjustable auto-fire button! But the most important thing in building it is FINDING the components. My initial idea was to use a push-button phone keypad. Although it would take a little getting used to (and you really couldn't use overlays), it would last a LONG time. Anyways, who actually USES the overlays! If a game requires them, just put one by the side of the controller.

As a side note... If anyone can find a place to get a nice keypad, a nice metal stick assembly, and nice arcade style fire buttons... All at reasonable prices... PLEASE let me know (ANA-NG@ix.netcom.com). I really want to build one of these suckers!

I hope this info gives you the start that you need so that one day you can throw those Intellivision Controllers where they belong... the trash!
