I didn't get the impression the Z80 was "expensive" - contemporary prices that I found placed the Z80 at something like $60 (or at least, under $100) and an 8080 at over $300? (but it's hard to pinpoint individual price vs bulk order, and normalize across those critical years of 1974-1977).
Also prices were volatile; announced at one price, and then up or down on demand
At Lockheed (then GD), when the F-16 was first being developed, I'm told they used Commodore PET's to do initial aerodynamics modeling because it's BASIC had floating point support. Obviously, that's not unique to the 6502
As did TRS80 ("Level 2 BASIC") where all numbers were single precision floating point by default!
also AppleSoft, and many/most? of the other Microsoft BASICs. -- Grumpy Ol' Fred [email protected]
