To add to Neo's Arduino subject matter I have decided to upload this in ".zip" format.
Ignore "*.info" files these are AMIGA icons only and also the "HAM" drawer as these are photos in ancient AMIGA HAM modes.
I have noticed that there are current converters to RS232 for USB Arduinos and this was my incarnation 11 years ago for the Diecimila Board. It should still work so long as "RXD" and "TXD" are the same pinouts as my board and it looks as though they are.
This gives everyone, even with old HW, a chance to have fun with Arduino.
The serial circuit is a modification of Arduino's original design on their very first Arduinos from yesteryear.
Irrespective of any copyrights in my stuff I categorically state on this post that you can do with any info as you please, this is a CC0, Public Domain issue.
NOTE: You can only use one mode at any one time, so ensure that the USB is disconnected when RS232 is being used and vice-versa.
Hopefully this does NOT attach to the previous post #4...
Hi Neo...
Here is another little snippet aimed at WinUAE, the AMIGA emulator, I created also around 2008-9, if you are interested...
