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.
