I liked being able to compile tightest code to fit the appropriate memory model. Tiny was a favourite with all segment registers pointing to the same segment. Another favourite was the huge memory model, multiple code, data and stack segments. Until the day came when one couldn't fit anymore in. I was glad when the mighty 386 came along.
It turns out that it wasn't actually necessary for a COM file to have the segment registers all the same. The Zortech COM file generation only required that the COM file be less than 64K. The startup code would fix things up so it would load and run.
