Could someone please enlighten me... What, pray, is FLEX?

Warning. Clock speeds may not be comparable. 6800 and friends
(including 6502) often do more per cycle than 2901s.

That said, the 4052 is a 16 bit system, despite its 8-bit instruction
set. The data path is 16 bit throughout, it fetches two byte
instructions in a single memory cycle, etc.

And Tek do claim some quite impressive performance boosts upgrading from
4051 to 4052 (average gain they claimed was ten times, I think)

Bear in mind Tony Duell's comments - 16 bit systems based around 4 2901s
used to be common, but may now be worth grabbing anyway.

I must do some more research into the relationship between 4052 and 6800
instruction sets.
