8080-Assembler examples

This is a collection of example programs and routines, for programming in 8080-Assembler on C/PM 80. This code is meant to be run on a Z80-MBC2 microcomputer, but can also run on any other 8080/8080 or Z80 machine, that runs CP/M 2.2. The code in these examples only uses iNTEL 8080 Mnemonics, in order to be compatible with CP/Ms built-in assembler. Some examples, however, require an extended VT100-Terminal, that can draw graphic-primitives via escape sequences. These examples will not work on a computer, that doesn't support them! The terminal used is Geoff Graham's ASCII Video Terminal, which is VT100 compatible, but also supports the graphics extensions.

The following example programs exist in the folder ./src

• HELLO.ASM: A simple "Hello World" program, that uses the print screen routine, calling BDOS.
• GRAPHTST.ASM: Tests simple escape sequences, such as clearing the screen.
• CIRCLE.ASM: Draws a circle on the screen, by printing the escape sequences on the screen.
• MANDEL.ASM: Uses graphic primitives to draw the Mandelbrot set to the screen.
