[net.unix] Ramtek 9400 drivers for 4.2 BSD

MEYER@RADC-TOPS20.arpa (08/15/86)

I would like to find out if anyone out there has a VAX 4.2BSD driver
for Ramtek 9400 color graphics displays.  We have two of them and
cna't get the driver we have to work with two units.  It's a strange
thing to watch a VAX slam to a halt when someone tries to access the
silly thing.

     Also, I would be interested in any utilities, libraries, etc. to
run these guys.

Thanx in advance...

I assume you mean a parallel interface driver rather than the serial
tty one. No. However, I offer a suggestion on the latter. It is
possible to load the Ramtek with instructions and then send it an
`execute display list' instruction. This beats the hell out of redrawing
an entire plane, but most people just do the latter. If you have
mountains of code, it is probably too late to change tactics as it is
a whole different philosophy. Good luck.
