Not sure whether this has been mentioned before, but it might be a trap for new players.(like me)
I programmed a short routine into a 08M which included a high interrupt on In3 and a high out on Pin2 early in the program. It loaded ok and seemed to run but when I tried to reprogram after changing a bit of code I got an error panel saying could not see Com 1???. Had me bug**ed for a while!! Checked circuit, lead etc (many times!!) then I realized that I'd set the interrupt on Pin2 not Pin3, so the 08m was trapped in a interrupt loop and the programming editor couldn't get it out. The only way to fix it was to click the program button in the editor and then switch on the power to the 08M before the editor com search timed out.
Just goes to show even the simplest little programs can screw you up...
