Hi all,
 
While I should have been working on something else (anything else!),
I came up with the following observations about the Interex
Vendors Guide.   The decrease in the number of vendors in the
Winter 1995 Guide is somewhat disturbing.
 
        Year   # Vendors       Price              Issues per Year
        ----   ---------       ---------------    ---------------
Spring, 1989      126          $475 for 3 issues      3
Spring, 1990      165          $475 for 3 issues      3
Summer, 1991      163          $475 for 3 issues      3
Spring, 1992      176          $475 for 3 issues      3
Winter, 1992      159          $475 for 3 issues      3
Summer, 1994      152 -1       $475 for 2 issues         2
Winter, 1995      120 -1       $475 for 2 issues         2
 
Notes:
   I'm assuming the "Winter 19xx" issue is the last issue of 19xx,
   since Winter starts in December ... but, since the issues aren't
   volume/number dated, I can't guarantee that they didn't come out in
   mid-winter 19xx+1.
 
   The "-1" for # Vendors means: subtract 1 for the Interex listing
   (Interex didn't appear in the Vendor list until after Winter '92).
 
   Yes, the price per issue went up 50% between Winter 1992 and
   Summer 1994...it just wasn't obvious at first glance.  :)
 
   1993 isn't available (i.e., our filing system isn't infallible).
 
   I didn't try to exclude non-HP3000 vendors, although I started to...
   then I quickly discovered that I couldn't just eyeball the list and
   cut out unknown names...some of them are 3000 vendors that I just
   am not familiar with (e.g., "id enterprises") ... but, it would be
   interesting to count the number of 3000 vendors, since the later
   years include a lot of non-3000 vendors (e.g., "Hummingbird" (9000)).
