An application that deployed 50 years ago and never updated would not run on 64-bit processors and would not be able to use the TCP/IP protocol suite. 50 years is longer than the average lifespan of any physical hardware component and it's not clear whatever drivers you had from back then would support any replacement part you could still find.

You can run legacy 24-bit mainframe apps on modern 64-bit mainframes fine. You can use legacy 3270 "green-screen" CICS mainframe apps over TCP/IP using CICS Transaction Gateway, with basically no changes to your CICS app. It's just that mainframe customers pay a lot for this convenience and stability.
