Hi.
Many years ago there was a partial port of AMPLE over to 26 bit based RISC OS. It's not however a version that could be easily patched 
I also found a general FORTH called !ArmForth (written around 1992/3 on an ancient FTP archive. This is largely 26bit based on the dates, but given it's source (supplied with it) appears to be ASSEMBLER+ FORTH it could be patched presumably.)
There is also a minimal forth called JonesForth (which had been ported on one repositry to work with an ARM EABI (Linux?) interface.)
I will note JonesForth was also 'extended' on Windows into BB4WForth (by Richard Russell).
Recombining BB4WForth (which is x86) and an ARM JonesForth could provide a suitable new Forth for RISC OS (Over which a new AMPLE could be developed), which could be made 32bit neutral at the very least. Of course the x86ism in BB4WFORTH would have to be recoded, but in general it is only the assembler portion that would need this.
(Jones Forth is an assembler bootstrap, with the rest of a Not quite Forth-94 system being coded in FORTH itself.
However, before porting anything,
I figured I'd check if this was something someone had already done.
So
(i) Is there a FORTH for RISC OS?
(ii) Is it 32bit neutral?
(iii) Does it meet Forth-94 (ANS Forth) ?
(iv) Does it support SWI calls? |

I think that the most complete Forth environment that was available for RISC OS is Forthmacs, ported in the mid-90s by Hanno Schwalm. Certainly not 32bit compatible, because the last version I am aware of is from 1997/1998. But at least it is StrongARM compatible.
You can still download this from
ftp://ftp.uni-stuttgart.de/pub/systems/acorn/riscos/lang/forth/forthmacs/
I know that Hanno Schwalm is still active within the Forth scene, so it would be worth a try to contact him. Maybe sponsor him a Raspberry Pi  |
