Zeus 64 Assembler Commodore 64 game

The heart of your Commodore 64 is the 6510 microprocessor, a derivative of the popular 6502 microprocessor. It operates in 6502 machine code. When you program in BASIC, a ROM program called the BASIC interpreter “translates” each statement, one at a time, into 6502 machine code routines. ZEUS 64 allows you to quickly and simply write programs in 6502 assembly language and assemble it into a single efficient 6502 machine code program. This gives you two very powerful advantages.

You are no longer limited to the commands in the BASIC language.

Many steps that are necessary to interpret a BASIC statement into machine code will no longer be needed. Therefore, the programs you write with ZEUS 64 will run much faster, and probably use less memory.

ZEUS 64 contains three separate modules:

The Editor, a fully tokenising editor which supports a whole host of features including; View source, Renumber, Delete lines, Multiple source files, Find and Change string commands, loading and Saving of source files to Tape, Disk etc.

The Assembler, for high speed assembly of source files into 6502 machine code.

The Monitor, a full feature monitor for direct inspection and manipulation of both the CPU registers and memory. The Monitor has no less than 20 commands including; Disassemble, Trace, Tabulate and Change memory, Fill, Hunt, Copy, Parallel printer interface, Hex/Dec conversion, Offset branch calculation, Loading and Saving of blocks to Tape, Disk etc.

Please note the short description above does not cover all the features offered by this powerful package, also the ease of use can not be described to those unfamiliar with ZEUS 64.

ZEUS 64 is the Ultimate machine code operating system for the Commodore 64 and is totally self contained, and takes up NO user RAM.
