Just arrived: prototype board and panel for a modular trigger to DINsync module. This one got so dense, i had to place a 74HC125 on the Backside of that board. But – finally – i had the opportunity to sneak in the first chip i ever used some 37 years ago, the glorious 7400 in a design. BTW its the proof in former times everthing was bigger; back then it was a DIP, now its SOIC. Big plus for this one: theres is no firmware do write.
