Every 8 bit platform needs a Forth interpreter. As I've ported TaliForth to the SBC 2 platform, I figured I could port it to an Apple 1 compatible without much work. The updated sources and build files are here:

https://github.com/Martin-H1/TaliForth

The build file depends upon a conversion tool which converts the binary into a Woz Mon script. The source is here:

https://github.com/Martin-H1/BinToMon

Rather than force everyone to fetch and build my conversion tool, I also checked in the Woz Mon script:

Upload using a terminal program and you are off to the Forth races.

I compiled Tali Forth to assume 32K or RAM which might not be available on a real Apple 1 or more faithful clone. I also found a Apple 1 Hex file of VolksForth which I was also able to convert to a Woz Mon script. It starts at address 1000, so it would work on a more compact RAM arrangement. Although there's sources in the Zip file, they require an Atari ST to build! As I am fresh out of Atari ST's, all I just checked the Woz Mon script into my Git repo for safe keeping:

Cool! Thanks for posting!

You should post the binary file too; by incorporating it into the firmware you can make it show up instantly as either ROM or pre-initialized RAM. To accomplish that, put the binary image file into the same directory as the Appl1SRAM project, e.g. as tali-l-star_5A00.bin (5A00 in the name is just a reminder where it expects to be loaded). Then use the Propeller tool to edit Apple1.spin as follows:

1. Below the line that starts with "rom: "Memory" ", add a new line that reads:
   Code:
   tali: "Memory"
2. Below the line that starts with "rom.StartEx", add a new line that reads:
   Code:
   tali.StartEx(@TaliFile, @TaliEnd, @TaliEnd, $5A00, 0)
   If you want to emulate the image as pre-initialized RAM instead of ROM, use "@TaliFile, @TaliFile, @TaliEnd" as the first three parameters (the second parameter changes to @TaliFile).
3. Below the line that starts with "RomEnd", add the following three lines:
   
   Code:
   TaliFile
           File "tali-l-star_5A00.bin"
   TaliEnd

Now right-click on the Apple1.spin window title and click "Top Object File". Then hit Ctrl+F11 while the computer is connected to the L-Star. This will compile the program and store it in the EEPROM.

From now on, your L-Star has Forth as soon as you start. All you need to do is (presumably) enter "5A00R" in Woz mon.

You could even change the reset vector so it starts Forth whenever you reset the 6502:

1. Insert the following above the DAT section in the Apple1.spin module:
   
   Code:
   PRI Patch(addrval, dataval)
   
     byte[addrval + @RomEnd - $1_0000] := dataval
   
2. Insert the following lines above the line that starts with "clock.activate...":
   
   Code:
     Patch($FFFC, $00);
     Patch($FFFD, $5A);
   

NOTE: as of this writing, I haven't tried it myself but I intend to do so; I'm pretty sure it will work. I'll probably add the result as a new project in my Github repo (suggestions for a project name are welcome ). I think I'll also play around with adding a video generator that gives the 6502 direct access to the screen (like the OSI emulator, but with a slightly less wonky memory layout -- the OSI video hardware kept counting addresses even during blanking which makes the memory layout weird).

Great, that will help a bunch.

I'll definitely check in the binary as well.

Looks like this is built for the 65C02, so it won't run on a true emulation of an Apple-1 (or real Apple-1), which uses the original 6502. Any chance you could produce a build for regular 6502?

(I realize this reply is about a decade late.)

TaliForth 1.0 is a dead Forth as TaliForth 2.0 is a complete redesign. So I stopped using it a while back and removing the C02 dependencies isn't worth it.

Does VolksForth need a C02 as well?

Probably the best strategy is getting FigForth running which is also in my repo as well.

Here is my Apple 1 figForth based off John Mathews ProDOS version. It requires the CFFA1 for the additional 32k RAM and screen storage: http://schmenk.is-a-geek.com/Forth.html
