I would hazard you'll never get it in one chip that cheap until
ten years from now. :-).  However, if you are diligent, you can
get by with two chips.  Motorola used to make
a "floating point ROM" - I believe MC6839 - which interfaced with
the 6800 family.  Basically, it was floating point emulation in
ROM, already coded and debugged for you.  You can get the source
from their BBS too.  Then you wouldn't have to code up floating point
(which sounds about as exhilarating as watching paint dry :-).
Although it'll take more chips, you'll have more spendable dollars too...
6800s are cheep cheep cheep.  And you can burn some EPROMs with code from
the BBS.  If you're truly a nut, you could run all the 6800s off of one
EPROM simultaneously -- sorta a SIMD architecture...naaaa, wouldn't work....

BTW, anybody out there got a description of Intel Hex format they can
e-mail me?  Much appreciated!  (I'll swap moto Srec for it too)
