Looking for working 4.2 BSD Unix AED frame buffer drivers

[Donn Seeley]

How about it?  We have a driver of uncertain pedigree which often
causes our 780 to crash when users do DMA.  We apparently have
something referred to as a 'Berkeley PROM' in one of our units and that
unit has proved to be completely intractable.  Even when using the
serial interface, AED users frequently have problems with overflow.
Nobody here (including me) knows much about the beasts so some of these
problems could be hardware, but a good driver (and some friendly
advice?) would help out a lot.  I'd appreciate anything you can tell
me about these things, especially about 'Berkeley PROMs'.

Thanks,
