Yow!!! That means maybe it will run FLEX! [insert

Could someone please enlighten me... What, pray, is FLEX?
Woo Hoo!. Dang! I can just imagine running FLEX at
25Mc! Its performance
over a 1Mc 6800 must have been blistering!
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)
Yikes!! I think I may have seen some boards from a
system like that one
in a junk heap last week! It used four 2901's eh? Hm, I'm gonna haveto
revisit that particular junque pile . . .
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.
