Hello Thorsten, Alex, and others, Thank you for one of the most interesting threads I've ever read! I like to consider myself relatively computer-adept, but I'm definitely a little out of my element here ... I like fiddling with older LEGO electronics; recently I've been playing with the 90s Control Lab and VLL with the scout, and I finally decided to conquer the Interface A. I have the Interface itself, a USB to TTL adapter, Arduino Nano, and a hodge podge of ribbon cables. I understand (based on your most recent post on this thread, @Toastie) that's all I need to get the interface running on my modern computer via DOSBox, correct? I'm only unsure about which arduino pins to connect to which pins on the interface. If you could help me figure that out, I would be greatly appreciative! Thanks for all your work on this, -Ry
