I have been working on a portable implementation of the Core System
graphics package, and have it running on the IBM PC and the Z-100 (two
graphics modes on each). All the 2D and 3D viewing transformations are
provided, but there are no retained segments, no input primitives, and
only string-precision text. I have recently contributed the source
code for the graphics package, along with two programs I have written
using it, to the info-ibmpc library. These files can be ftp'd from
directory <info-ibmpc.graph> on ARPANET host usc-isib:

I would like to see this package ported to other microcomputers with
good graphics, like the NEC APC and the DEC Rainbow. If you want to
help, please get in touch with me directly.
