Almost a John Titor Redux

I had to do a double take when I saw this because I had just been reading about the old John Titor time traveler internet hoax.
If you remember it, supposedly John "had been sent back to 1975 to retrieve an IBM 5100 computer which he said was needed to "debug" various legacy computer programs in 2036; a reference to the UNIX 2038 problem. The 5100 runs the APL and BASIC programming languages."
Then I saw this about the 5150.

Can You Do Real Work With the 30-Year-Old IBM 5150?

Yeah I know the IBM 5100 and 5150 are totally different machines.
The 5100 came out in 1975 and the 5150 came out in 1981.
But like I said, reading about that one thing then seeing the other....
