I have an IBM 5160 that has a BIOS ROM U18 with IBM part number 500026. The ROM is a ceramic package with a gold lid.
The motherboard is also slighly different than the two shown here:

Mine has an Intel 8088.
It also has the number 4073 stamped to the right of the silkscreen "64 - 256KB SYSTEM BOARD"
I read that nobody has seen one of these motherboards in the wild and have not seen this BIOS PROM.
Is this system one of the first XT's?
