I am living proof that there was an Apple /// Fortran. I was the Fortran /// program manager at Apple.
I converted Fortran Apple ][ to Apple ///. I brought it up to government specifications. The army was interested in the Apple /// but they required us to pass their own Fortran tests. They sent a crew carrying reel to reel tapes full of tests. We passed their tests with flying colors after adding missing rare facilities. We were ready to go package Fortran ///. After some consideration, for some unknown reason, Apple decided not to produce the product. I think we could have sold thousands of Apple ///s and opened up the government market.
could it be that by then,Apple corporate was ready to ditch the ///. and govt contract probably would've required Apple to keep after sale support going for years longer than corporate deemed profitable?
Was this Fortran for the Pascal environment (generating P-code), or a separate compiler project?
A version of Fortran for Apple /// Pascal seems to have survived. There are some disks here. The manual was provided as ASCII files on disks APPLE-3-WAP-PCL-17 + 18. Someone converted this to html here. The compiler itself is on disk APPLE-3-WAP-PCL-19.
I love hearing that. I skipped FORTRAN in my career, but nowadays have circled back to make use of some legacy codes at work. I'm finding gfortran and flang for arm64 don't work - compiler succeeds but runtime crashes, whereas on x64 it all works fine. Maybe I should try on 6502!
I am trying to use Apple III Fortran. I have created a disk from the Apple III Fortran disk image. I read the Apple III Fortran manual and it does not say how to update/modify the Apple III Pascal disks to use Apple III Fortran. Does anyone know how to update/modify the Apple III Pascal disks to make a set of disks for Apple III Fortran? I am using Apple III Pascal version 1.1. Also, the Apple III Fortran manual mentions a second manual that should be referenced for Apple III Fortran -- "The complete Apple Fortran documentation includes one other manual: Apple Language System Installation and Operation Manual". When I search the web for this document all that I could find is a manual for the Apple II computer. Does anyone have this manual for the Apple III?
