Drawing with GSX-80 on the xterm Tektronix 4014 terminal emulation. This
screenshot shows one of the test drawings from DRI's demograf CBASIC program.
Another CBASIC example program from an ancient german computer magazine.
In newsgroup comp.os.cpm was asked, if this will work too with cpmsim
build under Windows with Cygwin. Works the same as on any UNIX system.
GSX-80 also can be attached to any BASIC interpreter and so extend
it with graphics.
Everyone who had an Apple ][ with Z80 Softcard running CP/M knows
the graphics demos like this for the Microsoft gbasic interpreter.
Same can be done on any CP/M system with Microsoft mbasic and GSX-80.
DR Graph from DRI was one of the major GSX-80 applications. The program
was used to create business and technical charts, that even for nowadays
standards are not that bad.
The same graph, but plotted with the HP 7470 GSX driver into a HP GL/2
file and then converted with hp2xx. The Tektronix terminals are monochrome,
but HP Plotters have color pens and a HP plot file easily can be
converted to modern graphics formats.
DR Draw from DRI was the other major GSX-80 application.
