It has to be HW/SW compatible with the 16C550 UART. The only way to tell is for someone to buy the IC + PLCC-68 to dip adapter to test out on the Z80 V4 board. If this works, then we can add to the Z80 V5 board.
For removing PLCC IC’s from the sockets, I learned back at DEC to use a very, very small screwdriver to lift one side first and then the second slowly to avoid putting a lot of force into the socket. I never had any issues with this technique. The extractor tool never worked for me.

Or we could use the 16C550 PLC44 on CPU bard.
The parts I'm looking at are 16C554. All are the same 16C550 UART logic replicated 4 times.
Regarding using a screw driver to pry out PLCC parts... I always
knew you were more than a mere mortal!
The only hit to buy is on eBay. Did you find another place to buy from?

I did not check other places, but digikey seems to have them
