    Known Problems

    NeXT SQA has experienced some display problems with the ATI Mach32 VL-Bus adapter on machines using the OPTi chip-set. One of the problems is the machine will hang in any of the 8-bit greyscale display modes. However, machines without this chip-set behave normally.

    NeXT SQA has witnessed some video noise in 800x600 display modes for adapters with the 68003 Mach32 chip.
