The IBM 5080 and 6090 Graphics Systems are designed for polyline CAD/CAM applications.

GDDM/MVS, GDDM/VM, and GDDM-PGF communicate with the 5080 and 6090 through GDDM/graPHIGS, a separate IBM licensed program. This support allows graphics applications written for other devices to be run on a 5080 or 6090. Interactive graphics applications written for other types of display can run on these graphics systems but do not take advantage of their full capabilities.

The 5080 or 6090, with or without the 3270 feature, has interactive graphics capabilities that can be programmed like those of a 3270-PC/G or /GX.

The main differences are:

The 5080 or 6090 must be explicitly opened by a DSOPEN call.
Neither the 5080 nor the 6090 has a mouse input device.
Valid choice devices are:
- Enter
- PF key
- PA key or CLEAR, by switching to 3270 during read operation
- Puck/stylus
Valid locator echoes are:

0
Small cross
1
Small cross
2
Crosshair
3
Tracking cross
4
Rubber band
5
Rubber box
6
Draggable segment. The whole of the segment appears white.
When using rubber band and rubber box echo types, if the position of the fixed end or corner is not visible at the time of a GSREAD call, GDDM does not ensure that the initial position and type of the locator echo are correct.
