I wonder if John Titor could have used this?

Unlike the IBN 5100 [1] (which I guess actually was IBM's First Laptop Computer), the 5140 ran MS-DOS, and couldn't emulate the IBM/360 ISA like the IBN 5100 could, so it would be useless for John Titor because you couldn't hack SERN with it.

Nah, that would have been made by IBN, a completely different company.
