I pulled the LED controller board out of my #Teletek #systemaster #s100 machine. I think the comparator chip has failed? Anyway it was responding to writes of all the IO addresses. Very distracting. And it made me worry that it was going to mess up the signals.
So my CP/M machine now seems fully operational again! Woot!
