Notes
1. The Z-suffix denotes a HCRX-board with an optional 3D-acceleration board, containing a hardware 24-bit Z-buffer. These combined adapters (e.g. HCRX-24Z) support
the same visuals as stand-alone versions (e.g. HCRX-24) but always provide the 3D acceleration. The hardware acceleration can only be used in conjunction with the
Starbase, PHIGS, PowerShade or PEX APIs.
