Hmm, and there is another possibility: try checking if the IC sockets of the 8501 and the 8360 are still in a good condition, and they're not oxidated. Also, try swapping the 8360 and / or the 8501 by replacements from an other Plus/4 or C-16. These problems could also happen if the TED was unable to generate interrupts to the CPU (as both the keyboard and datassette motor is handled by an interrupt routine). Whether this is because of a bad TED, a bad CPU or a bad contact between them, they'd all result in not handling both the keyboard and the datassette.
