North Star Advantage Z80 Computer Emulator (ADE)


1978 North star Horizon ad.



ADE is a North Star Advantage Z80 Computer emulator for linux/unix systems. The North Star Advantage was an all-in-one Z80 Computer which was released at the end of 1981. The Advantage had a video screen which was bit-mapped meaning that graphics as well as text could be displayed. The graphics capabilities were included in the GDOS,GHDOS and the GHBASIC software which North Star provided with the Advantage hardware. Also fitted into the integral case was a keyboard and spaces for two disk drives. The Advantage was presented with two main options: either with two floppy disk drives or with one floppy drive plus one hard disk. The early North Star 5" hard disks were only 5 megabytes, but were later progressively upgraded to 10, 15, 20 and 30 megabytes as the prices of 5" hard drives fell.

ADE will run much of the software written for the Advantage by North Star Computers in the few short years that the Advantage was produced.

This is the initial public showing of the ADE emulator. ADE is still VERY MUCH in ALPHA release. It shows its ncurses-based ancestry and has two windows:

The main window emulates the Advantage Video Display and shows in green.

The obsolescent monitor window is mainly used for showing various status information and also used for text input as when 'mounting' floppy-disk image-filenames. It shows in amber text. This monitor window will be replaced by GUI controls in later stages of ADE development.
