NASCOM 1 & 2 hints & tools

The code should work with both NASSYS and T MONITORs, and is located by default at $1000.

Quick start

zcc +nascom -lm -o adventure -create-app adv_a.c


zcc +nascom -clib=ansi -lm -o adventure -create-app adv_a.c

This command will build a file called “adventure.nas”, an HEX formatted binary file suitable to be run on the existing emulators.

It is possible to choose a full VT/ANSI emulation or a tiny console support. The ANSI version of the library depends a bit less on the ROM because the video memory is addressed directly.

You can also change the program location with the “-zorg=” option. The default position is at address $1000.
