In this change I have split the /preForth directory into /common and /i386 and I have also split some of the Forth sources into bit-width depedent and/or direct/indirect threaded dependent files. So in the /common directory we now have
hi16bit.forth
hi32bit.forth
seedForth16bit.pre
seedForth32bit.pre
and these are prefixed to the similarly named files hi.forth and seedForth.pre to set the minint and maxint values, whereas in the /i386 directory we now have
seedForth-i386.pre
seedForthRuntimei386.seedsource
and these are suffixed to seedForth-i386-rts.pre and seedForthRuntime.seedsource respectively to define some critical words implement the compiler or does> system, allowing us to insert call instructions for direct threaded and so forth.
And then I have added the following new directories:
/asxv5pxx contains a local copy of the GPLv3-licensed ASxxxx assemblers, (as a submodule that references my nick4 account on github), for bootstrapping. See https://shop-pdp.net/ashtml/asxxxx.php for the original source of these files.
/emu_z80 contains a local copy of the MIT-licensed Z80 emulator at https://github.com/superzazu/z80 (as a submodule that references my nickd4 account on github), and a wrapper that t I developed to provide preForth-compatible I/O facilities.
/z80 contains a copy of the /i386 directory with appropriate changes: fasm i386 source changed to asz80 source, Makefile changed to build bin files and run via the emulator, 32-bit changed to 16-bit, indirect threaded changed to direct.
You can run ./seed and ./seedForth-tokenizer in the /z80 directory and they work pretty much the way they do in /i386.
