MEGATEK 7xxx/33xx series

workstation type:

63000; Changes have been made to the driver so that the workstation type 63000 may be used for any Megatek hardware configuration (except in the case where two displays are to be run simultaneously on a single controller). This is performed by reading information stored in files that are created by the WANDGEN utility, and which are accessed via the logical names WAND$CONFIG and WAND$SYSTEM. Information on these files will be found in the WAND Installation Guide, Section 4.

Setup:

The hardware configuration is assumed to include a tablet and/or joystick plus a HCRST3 3D hardware transformation unit. Parameters may be set in the routine GKM9ZZ specifying the following defaults: driver interface (Parallel=GX or DR11W=MG), Raster or Stroke device, Monochrome or Colour, Display List size, availability of 3D surface processor, screen size, allocation of Display List memory if several screens are available. Note that if the interface card is specified as being MG, then one can use a GX interface simply by creating Logical Assignments of MG0..8 to GX0..8 (or vice versa).
