I have recently adapted a PC to use the TOPS network. This allowed me the
ability to file interchange from the Macintosh to the PC. However, I really
fell in love when I found that I could now print my Acad drawings to the
LaserWriter using their driver to print a PostScript file. If this
interests anyone, I'll be happy to upload a description of the process. It
does require the purchase of a board for the PC and some software, however
the output is wonderful!
