@wyatt i'm not completely sure, i'm not an expert at diagnosing old computers, all i know is the two broken ones don't show any image on power on. one of them is really beat up and has some missing keys, another smells really weird and has double sided tape all over it.
and unfortunately i'm not really able to ship stuff at the moment for personal reasons (and if i had a PET style keyboard i wouldn't want to let it go anyway lol)
