Sure. The source code to Chuck's assembler for MuP21 fits on one page.
I posted the P21Forth version of Chuck's assembler some
time ago. The FPC version is a little longer than the version on the
the MuP21 because since FPC is 16 bit it must use adouble number to
hold the 20 bit MuP21 words.
Chuck's code that comes with these systems contains:
Code to program a PCMCIA card connected to several of parallel ports
on the PC. ( a diagram is available to contsruct a PCMCIA card programmer)
(I added a patch to use BIOS supported PCMCIA card drives on desktop and
laptop PCs)
An assembler for the 8 bit boot instructions.
A sequence of 8 bit boot code to boot from 8 bit ram to DRAM.
A DRAM load routine.
A 20 bit instruction assembler.
A routine to initialize the video processor instructions.
The display and menu handling routines in OK.
Part of the OKAD system on MuP21.
Dr. Ting's character output to video routines, and hex dump.
Dr. Ting's graphic load and decompress routines.
And various text and graphic demos in the menus of OK.
In addition Dr. Ting provides several utilites to load text and
graphics from the PC into MuP21 format.
