Did any computer built after 1960 NOT have a FORTRAN
implementation?
Yes, my ICT1301 (155+ built from 1962 to 1965) had no Fortran compiler.
I've not seen a Fortran compiler for any of the following :
HP9830 (I claim this is a computer, it ran BASIC from ROM)
Philips P850 (maximum 2K words of core, I believe larger P800 series
machines did have a Fortran compiler available)
HP9825, 9831, 9845, 9835 series
HP80 series.
Just about all the pocekt computers (Sharp, Casio, HP, etc)
What abotu the IBM 5100? And for that matter the Commodore PET (I know
the SuperPET had such a compiler), the C64, etc. And the Sinclair/Amstrad
machines (ZX*0, ZX81, Spectrums). And the Oric
How many of the above would run *any* type of compile-to-machine-
language HLL compiler? Most of the BASICs were tokenized and
interpreted.
A few of those that you've cited simply didn't have the resources for
it.
