I am intending to participate in RetroChallenge 2021/10.  In order to register I need to submit a URL to a picture.  So I am posting this picture for that purpose.  While I am here, I guess I can mention that it is a photo of my current development setup.  I write ESP32 code on the black laptop.  I write AppleSoft BASIC code on the //e and //c using Beagle Bros "Program Writer".  The //e has the apple2idiot expansion card I designed in (slot 2, this is where the ESP32 lives).  I prefer the keyboard of the //c, so, I do big bouts of code writing and file management stuff on the on the //c and then swap the code over (via floppy disk) to the //e and run the software and fix bugs.  Ta!
