yeah i am pretty sure BMOW has this very same issue with his Floppy Emu, The screen goes weird every time plug it into this 512k i have here, The thing works but might have some dirty power output or something.

maybe i should ask em to put a nice volt meter on the screen of his floppy emu??? that would be useful… pop on and you can see right whats/what. make it more useful and more of a diagnostic tool as well!

maybe just a one liner at the top? +12=XX.XX -12=XX.XX +5=XX.XX

. 5 -12V

. 6 +5V

. 7 +12V

. 8 +12V

or go the extra mile and program in limits… and the floppy emu says… HEY YOUR PSU IS NOT GOOD DOOD! FIX IT! hahah that would be Cool!!
