Yes, TranScript is the only program I know of that correctly converts
the old troff (for the Wang C/A/T phototypesetter) to PostScript

Try specifying the device "aps" to eqn, e.g.,
$ eqn -Taps file | troff -Tps | devps | lp
devps uses an internal resolution of 720 DPI, which is very close to that
of the aps-5 (723).

Specify the resolution to pic as -T720, or -Taps:
$ pic -T720 file | troff -Tps | devps | lp
Note that the default resolution for pic is 300 DPI (Imagen 8/300 was used
by many of the folks at Murray Hill).

This is a bug I wasn't aware of; I'll fix it and send a update to SSC.
If you want me to, I'll post the fix to the net.

Note, you should READ the Devps User's Guide that is distributed by SSC.
It tells you what to do to get eqn and pic to work right.

P.S. If anyone has any questions about devps, please send them to me via
email so we don't tie up this newsgroup.
