Well, I'm not sure. In 1996 I built a laser photoplotter.
for some description and a picture. It ran on a Windows 3.1
computer with an ISA bus DMA card.
I was still using it to make PC board artwork and stencils
for solder paste up to 2014, but was worried the old PC
would fail to boot someday. The program that generated the
raster image files was written in Turbo Pascal for Windows,
run under a virtual machine, and I was not sure I could
recompile it, either. I used fpc (Free Pascal Compiler) to
recompile it and clean up a bunch of things, then wrote a
program that used run-length compression to compress the
raster file. I got a Beagle Bone computer, and wrote some
code for the PRU to uncompress the run-length encoding on
the fly, and emulate the DMA card on the PC. I got all this
working in a matter of weeks, and felt REALLY good! I
haven't done that sort of software/hardware project in quite
