An assembler for the SPEW language/CPU

Already found a bug with the hex numbers. Sorry, however, its fixed now.

The SPEW language/CPU was invented for the Hugi Compo #9. It is a simple language/CPU that has 4 registers and 18 instructions. This fictitious CPU is a 12 bit CPU.

With my entry to HC09, I included a small assembler to assemble a given corrected syntaxed source file, to an appropriate 4k SPU image file. This is the reason for this page. I am including the source for the assembler here for the benefit of the Hugi Compo group as well as anyone else who is interested.

Please note that as of today (12 Nov 1999), the assembler is a basic core and not a complete assembler. It does not check for user errors or syntax of the source file. Maybe in a later release I will add error checking.

The included SPU.ZIP (19k) file contains the following files:
- DEMO.SAM (the demo source code)
- DEMO.SPU (the SPU image file created with SPU.COM)
- DICE.COM (a very well written debugger for the SPU image file written by TAD)
- RULES.TXT (the rules included with HC09. A file describing the SPEW CPU)
- SPU.ASM (the source code (x86 assembly) to the SPEW assembler)
- SPU.COM (the assembler) ver 0.91
- SPU.TXT (information file describing the usage and syntax of SPU.COM)

Let me know if you have any questions or comments about the SPEW language or the SPU assembler.
