Hello Thom, sorry for the delay to answer! I use an Arduino Mega to read/program the Dallas chip. I can send you the script with wiring instructions if you want it.

I actually have a few of those lying around, but I don't know which type they are (re the document provided by modem7). How can one tell one type from the other looking only to the led board? Update: added pictures

If anybody is interested, I put my Cauzin Softstrip Reader for Apple IIe on auction on eBay. Item number is 231475092377.

Hi all, My name is Sylvain and I'm in the upper half of the 40s, so I grew up with the computer revolution. I got hooked to electronics and building mechanical stuff before turning 10, and I never quit. I studied electronics (analog and digital), programming, and physics. I got and used a lot...
