FigForth running under RomWBW [message #9248]

Has anybody ever considered replacing the CamelForth that is in RomWBW with FigForth?

I have been experimenting with it, and I can't get my head around the loading sequence - I am pretty sure I have it concatenated in the image, but it is a little larger than the Camel, at about 1C00 butes, instead of 1700 bytes.

Any clues would be very much appreciated.

Forth occupies rom bank 2. There is free space in that bank that is allocated to the "user" rom which is designed to allow users to easily add a custom rom. However as currently configured, it has to be a maximum to 7k, so too small for your use.

To replace the current forth image you need to set the new size in std.asm - FTH_SIZ equate
update the Forth build process in the Forth directory to generate your binary image at that size.
Update \hbios\build.cmd to concate your new file i.e replace copy /b ..\Forth camel80.bin + etc etc

I think that's it.

Much easier than it used to be Smile

Hi Doug,

Sorry, I just saw this thread. Phil is correct about the way to do this. Are you making any progress?

Thanks,

Wayne
