      Hello, Jeff, my compliments.

      Thanks for the Web link and your compliments about Dave's Web page.
      I've added the IBM link to "my" PDP-8 Web page. In due course I'll add
      your plotter comments here as a description there, with your
      permission. Thanks!

      You might compare them to the Calcomp manuals which Dave links to on
      his site.

      Preprinting is no big deal; one could reverse the roll. I'd like a few
      rolls for my plotter; I presume MARCH would like a few. I'd be glad to
      pay shipping for some rolls and pass a few along to MARCH. I'll
      contact you privately to discuss terms.

      Greatly appreciated, I'll add them to the page, you can send them to
      me. Let me know if there are any photos I need to take of *my*
      plotter. Presuming Evan permits me to restore the MARCH/Kagan plotter,
      I'll photograph it while in process.

      Hmmm...this bit of work may evolve into a permanent Calcomp plotter
      Web page on my (retrotechnology.com) Web site. Ultimately I presume
      MARCH will have their own PDP-8 Web page with other bits like the
      plotter, TTY, any papertape reader MARCH comes up with).
