  1. I have Googled my a** off for half a day today trying to locate a
    complete reference to the HPGL plotter language. I have found many
    references to the subject and snippets of code here and there but
    nothing complete. I just bought an old Encad SP600 plotter and the
    program reference guide is missing. The device does recognize the HPGL
    instructions. A link to a site would be appreciated.
    Thanks,
    Frank P

    Try going to this address:

    http://sinfor.lcs.mit.edu:8180/pcbmill/index.html

    Download the "source code" (kind of large). Unpack the
    tar.gz file, and in the "doc" directory is a file called
    ctechref.pdf, it is 4.7 Mb and contains the complete standard
    for the laserjet and HPGL plotters.

    If you don't have a clue what I am talking about, I suppose I could
    email you a copy, it is 4.7Mb, though.
     
  3. Thanks Chuck,
    I have downloaded the file "pcmmill-0.98.tar.gz". What utility do I need to
    unpack this file. I only familiar with PKUNZIP. Is this a unix file?

  4. Winzip opens the .gz and the .tar formats, but here's a direct link to
    a copy of the PDF:

  5. Thanks a lot Sphero. This is exactly what I have been looking for. I know I am
    stepping into the past by messing around with a plotter, but it's something to
    do.
    Thanks again,
    Frank Pickens

  8. Thanks Boris,
    This site also looks promising. I appreciate the help I am getting here. I have a
    fantasy that I may take an old flatbed plotter and develop a system to paint the
    resist on a crude PB board. I do a fair amount of single sided boards in pursuit of
    my hobby and still can piss away most of the day getting a board ready to etch. If
    I am able to get a working (and practical) system I will publish it here for all
    interested parties.

    Thanks again,
    Frank Pickens
