Hello
I have an old computer which communicates TTL pulses via a parallel port.
My question is if I want to replicate this on a raspberry 4, from a hardware point of view do I need to do anything more sophisticated than connect the appropriate GPIO pin with the correct pin on a DB25 connector?
Many thanks for any advice
Michael
