If you let me design the race-course, I can beat a Ferrari with a 1950's
VW bus.    Or, to be closer to on-topic:
If you let me design the benchmark, I can prove that a TRS80 is faster
than a current Dell.

Landmark was extremely popular with vendors, because it made the most
trivial enhancements seem major.


Although it was CLOSE, usually acceptably so, it was not COMPLETELY
plug-in compatible.  For example, the Gavilan required some trivial
hardware mods to use it.
