its a great ST to PC conversion!!
yeap it's great. I want to do the same to my STFM.
That's what they are talking about here.
Ahh. I had not read the 10 pages of thread, but saw the title, and thought that people should know about the Atari Turkye design, as its the best I have seen.
@Bit, @Fred: This whole fred is about a proven, simple and working ST keyboard conversion (hence an ST PC conversion follows), using just Joskas fast and simple micro controller (Arduino/Teensy) adapter.
Fast, cheap and working. And much less work than any wire based solution.
Just my 2 cents,
IMHO, your 2 cents are correct. I understand little about the Teensy. But the Arduino, I think, although far more powerful than required, is the ideal board for the job. And I will tell (bore) you why:- (ahem)
1. The Arduino is very popular, and can be ordered pre-assembled and complete for a very low price.
2. Even the most technology adverse and non-programmer/electronics-ist (is that a word?) person, could download the Arduino 'Sketch' (the actual microcontroller code) and flash it to the built in chip. How? Well its easy. The Audiuno is designed to program from USB of your main PC, and its as simple as loading the sketch into the free and open-source software for your PC, and then plugging in the Audiuno with the supplied USB cable, and selecting the program button. Simples!
3. There are a range of low-cost "Shields" for the device here http://shieldlist.org/
that I am sure would make connection of the required connections easier, IF, there was needed say a PS2 connector, or another connector that was felt necessary, there are shields with 'standard' connectors or even "screw down terminal blocks (so just the wire colour instructions are needed to connect the ST keyboard"), or maybe .... and I am just looking at a unencased standard ST keyboard now ... the connector on it looks like it will go straight onto the PCB header on the basic Auduino board... maybe the power line needs to be clipped and removed, but thats all!
4. The basic Auduino has a USB port, but it would possible to either
i) program a standard Microsoft compliant driver for USB into the Auduino (harder, unless sketch can be nicked from elsewhere) - or -
ii) read and convert the signals generated from the Atari keyboard and translate to the serial code used in PS2 connections (which is a very basic code used in IMB contemptables, and Intels since the 8086 I think!!)
This would certainly help to make a very faithful Atari ST to PC upgrade possible, and open it up to anyone who wants one just by uploading the sketch, and one or two simple and easy to follow wiring diagrams. I appoligise if I am repeating anything, but I only had enough patience/time to read through the first 4 pages of this looooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong thread.
