I've used the JLASER card. It was really

I had a switchbox at the input of my printer.

running on "Freedom of
Press" software postscript emulator (at BPS, who were printing my Comdex
sign), learned the performance consequences of an undersized stack.

Its a matter of speed and available ram to manage for data. Postscript
looks very much like and works like FORTH, the graphic operator add to
it but the base language is still a stack language. So when you put a
graphic object on the stack there better be room.
