We just got a Datacube Max Video here. The drivers one gets with it are
for the sun with VME bus. Does anyone have the drivers already ported
to a microvax with ultrix 32 or even 4.{23}BSD?
I'd appreciate any help.
Thanks.

I don't see what you are going to do about that - and whatever device you use to make the connection is going to affect any "port" of the MaxVideo driver software. We have a couple of the MaxVideo boards running happily on a Sun3/160 - it wasn't much hassle at all. There are two major versions of the driver software: the old and the new. The old one simply let the user map the 4Mb of VME address space that the MaxVideo boards sit on into a user process. Then you could do anything you wanted with the boards by just stuffing bytes, but you couldn't accept interupts (etc) from the boards. The new one is a "real" device driver, but we still aren't using it as of yet. ..jOhn -- John Robert LoVerso @ SUNY/Buffalo Computer Science (716-636-3190) LoVerso@Buffalo.CSNET -or- ..!{allegra,ames,decvax,watmath}!sunybcs!loverso
