Does anyone have the pin-out specifications for a Koala Pad? It is a pressure sensitive drawing pad made for the old Atari computers. It was made by Koala Technologies Corp, and is model #004. Before anyone tells me that it has awful resoltion and that I should buy something better for my amiga, this is free and sitting in my lap at the moment.... But if you did know its resolution I wouldn't complain if you told me. :) My primary interest in hooking this up is to provide an easy to use drawing medium for 2 to 3 year olds..... and if the resolution isn't too awful, for doing some of my own drawings... Oh yeah, one last detail. It has a standard 9 pin joystick connector. Thanks for your help, Joe Peck peck@ral.rpi.edu

Point being: the +5 and ground pins and the (joy)stick "direction" pins seem to be the same else the C64 joysticks wouldn't work as well as they do on the Amiga. Thad Floryan [ thad@cup.portal.com ]

So anything that reads the pot inputs on the Amiga would be a good place to start. I wouldn't be too surprised if you had to rearrange some of the pins though. -- Blaine Gardner @ Evans & Sutherland 580 Arapeen Drive, SLC, Utah 84108 blgardne%javelin@dsd.es.com ...dsd.es.com!javelin!blgardne (I hope) {decwrl, utah-cs}!esunix!blgardne DoD #0046 My other motorcycle is a Quadracer.

It uses the paddle ports on the C=64, and can be read with the Amiga, but I have not seen any software designed to use paddles (that's what the pad would replace) on the Amiga. -Todd PS: Our PNews has been acting up could someone let me know if they see this other than at Acadia.

Although he didn't actually say, enough other people have so it seems that the pad is a resistive type. A little proportional input reading should work just fine. I would like to thank everyone for their help, I only have one of these. I would have hated to have fried it by guessing..... Joe peck@ral.rpi.edu

BIX: blaine_g I don't know about the Apple ][ version, but the C64 Koala Pad can indeed be hooked up to the Amiga. No pin changes are required, but 1 resistor internally must be changed because of the different sampling rate on the Amiga. The pad looks like a proportional joystick, and a little driver to make it produce input events from port 1 was fairly simple. The only problem was that Intuition, prior to 2.0, went right to the hardware looking for mousebuttons for its gadgets and menus. Except for this irritation, I have had the pad working with DPaint III, and under Release 2.0, the buttons aren't a problem anymore. Works fine on the 3000, too! If anyone wants to post the code, send me a disk, and I'll send back the driver and a schematic. Please use email to get my USnail address.

In-Reply-To: message from thad@cup.portal.com I'm pretty sure the Koala pad was read just like a paddle on the Commo Commodore 64 and probably the Atari also. ------------------------------------------------------------------------- ProLine: danb20@pro-graphics *************************** UUCP: ...crash!pro-graphics!danb20 * Dan Bachmann * ARPA/DDN: pro-graphics!danb20@nosc.mil * Raritan Valley College * Internet: danb20@pro-graphics.cts.com *************************** P-Link: DanB20 <-- I only read PLink once a mo. use Internet U.S.Mail: 509 StonyBrook Drive, Bridgewater, NJ 08807
