I'm looking for ANY information about how to program the IBM 615x family
of display boards for the IBM RT/PC, in particular the 6154.  I am running
ACIS 4.2 UNIX and there is NO IBM supported graphics on these displays. The
device drivers have just enough to bit-blt text into the buffer and the
board has too many magic registers that are used but not documented.

What I am trying to do is port my distributed GKS system to the RT.  I have
ported the device-independent parts but can't do anything about the device-
dependent server that drives the display.

Any information or code (however hacked out it is) would be greatly appreciated.

I have heard that Larry Weissman at the University of Washington has done
some work in this area however, the I can't seem to get e-mail to him.
If your reading this Larry, I like to hear from you.
