  I have just uploaded a slightly crippled version of my
  CirCad schematic drawing program.  Yep, another "crippled
  DEMO".  The drawing functions are all there, but the file
  input/output functions are dead, except for the file I/O
  from the edit buffer, which works.  I left that part in to
  allow users to trade little diagrams and saved "objects"
  easily and maybe make some of the explanations in technical
  discussions in the forum a little easier - just send a
  diagram.

  Circad draws diagrams on the MM/1 screen and writes them to
  a file in the PostScript printer control language.  A
  second file stores the coded drawing commands in CirCad's
  own format.


  It includes a set of basic drawing tools and a few extra ones,
  and some built-in electrical and electronics schematic
  symbols.

  The program came about when I was preparing a schematic
  drawing for the electricians at a local factory where I had
  recently installed new electronic controls on a heating and
  air conditioning system.

  I had (finally) convinced GhostScript to compile and run on
  the MM/1 and I thought it could draw a neat diagram if I
  could write the file.  I drew the schematic on graph paper
  and translated it into PostScript (with help from some
  reference books), writing the PostScript file with a text
  editor.  The diagram looked great, but writing the
  PostScript file was a long job.  At this point, CirCad began
  to develop.

  CirCad is being distributed by Mark Griffith's "DIRT CHEAP
  COMPUTER STUFF Co." Contact Mark for price and
  availability. (Mark is 76070,41 on CIS, MARKGRIFFITH on Delphi)

  I will be at the coming `fest' in Atlanta.  Look for the guy
  with the shiny head and glasses, drooling over the other
  goodies at Mark's booth and trying to decide if he wants a
  tape drive or a floptical.  (or a CD-ROM, or ALL of em - all
  I have to do is hit the Michigan Lottery).
