Did you look at your files in something like the mc file viewer?  ps
and eps are also readable text, if confusing.  pcb files are easier.

I'm not super familiar with the pcb format but this looks like the
conversion sets up a board then doesn't put anything on it:

PCB["" 850000 1100000]

Grid[1000.000000 0 0 0]

Layer(10 "silk")
(
)

If you want to read/write Postscript I'd start with the Postscript
Language Reference Manual
https://www-cdf.fnal.gov/offline/PostScript/PLRM2.pdf  I've written
some, or written programs that write it.  It's good for getting a
totally unscaled output from your laser printer that you know nobody's
messed with.  I made a guitar fret/note chart with it last.

Does ps2edit have a -v option (verbose)?  Is that a raster image?
Mostly Postscript can bundle formats like tiff into the postscript
file verbatim.  It doesn't come back out of ps2edit, which may only
work with vector.  Can you make an svg and have it work?  I think you
want something that actually draws the lines, like with a pen.
Postscript can do that, it's like plotting languages that can do "pen
down" "move to".  Or it can carry a raster image.

No, I won't  call it "climate change", do you have a "reality problem"? - AB1JX
Cities are cages built to contain excess people and keep them from
