Notes
1. The Stinger CRX adapter, integrated into some of the older ASP-based workstations (older 715, 725), supports four different resolution/refresh-rate combinations, which
can be changed via a DIP switch on the back of the machine or in the PDC.
2. The Artist graphics adapter, as found on many LASI-based workstations, is technically identical to the CRX devices but supports much more resolutions and refresh rates,
which can be configured in the boot ROM.
3. The Z-suffix denotes a CRX board with an optional 3D-acceleration board, containing a hardware 24-bit Z-buffer. These combined adapters (e.g. CRX-24Z) support the
same visuals as stand-alone versions (e.g. CRX-24) but always provide the 3D acceleration. The hardware acceleration can only be used in conjunction with the Starbase,
PHIGS, PowerShade or PEX APIs.
