This directory contains printed circuit board artwork for the 6.270
MIT Robot Design Competition hardware.

Note: This artwork is Copyright (C) 1994 Fred Martin, Randy Sargent,
Karsten Ulland, Anne Wright, and MIT.

Permission is hereby granted to use this artwork for any purpose,
commercial or otherwise, provided that full credit is prominently
given to the original authors of the work.


* The following files are Gerber-format text files:

	6270v221.aps		aperture definitions
	6270v221.com		component side traces
	6270v221.hol		NC drill file
	6270v221.sil		silkscreen side pattern
	6270v221.sol		solder side traces


* The file "rev2.1-schematics.sea.hqx" contains the schematics for the
  board, done using the DesignWORKS schematics package for the Mac.
  These files are perfectly useless unless you have this particular
  piece of software (it's also sold by Douglas Electronics).  Please
  don't ask me to provide schematics in any other form; PostScript
  versions of the schematics are included in the documentation.


* File "6270v211.sit.hqx" is a Binhex'ed version of a StuffIt archive
  (for the Mac).  You will need "StuffIt" or "StuffIt Deluxe" to decode
  the archive.

  When you are done decoding, two files will be created:  the foil
  patterns and the component silkscreen.  These PCB files were created
  by the Profession Layout (R) software package sold by Douglas
  Electronics, Inc.
  
  You can send these files to Douglas Electronics and they will send you
  film panels which you can bring to your favorite PC board manufacturer
  for board fabrication.  When you send the files to them, make sure to
  request: component layer, solder layer, component layer solder mask,
  solder layer solder mask, silkscreen layer, and drill guide.  These
  six panels are used by your PCB manufacturer to make boards.
  
  Douglas Electronics can also do the PC board fabrication if you like,
  but they are pretty expensive (though convenient).  Talk to them for
  pricing and delivery.
  
  Douglas Electronics can be reached at: Douglas Electronics; 2777
  Alvarado St; San Leandro, CA 94577; (voice) (510) 483 8770.

Please let me know if there are any question or problems with using
these files.
