We are just now getting a 4115P51-upgraded-to-a-4128 operational,
which will then be upgraded to a 4129.  Anybody got any good C low
level host software to format commands and send them through the
serial and/or DMA lines to this beast?

(Including a 4.2-ized device driver.  The DR-11 + block handshaking DMA
driver we got from Tektronix is for 4.1aBSD. I hate reinventing wheels.)

I would also be interested in a C .h file describing 3D display-list
opcodes for DMA, since the DMA manual we got was written for the 4115
and only has 2D opcodes in it.

Background:  The Tek 4128 is a 3D, segmented display list device with
editable segment hierarchy and a raster display engine.  The 4129 has
hidden surface and shading capability in addition.  We are going to
use it for interaction with the Alpha_1 B-spline-based solid modelling
system, developed here.

Thanks in advance.
