Hi,

Here's when various terminals were introduced and when they were
discontinued, along with their prices:  (Note: I didn't check pre-1979
or post 1985)

   2625A |     -       -       -        -      -  $3495  dual, opt graphics

Note: all 264x terminals with entries in the 1980 column were
available and priced the same in 1979, as well as the 13290B.

Model/price information based on entries in the yearly "HP Test &
Measurement Catalog".  Thus, the granularity is a single year.
(prices don't include cartridge tape ($1600 extra)/ floppy drives,
where available)
(I didn't check for discontinuance of any terminal past 1985.)

In 1985 , HP suddenly realized how important computers were,
so they were moved to the front of the T&M catalog!

Personal Computer Notes:

   125, 120       Introduced in 1984.   gone by 1985
   150, 110       Introduced in 1985.   gone by 1988

HP 300 note:

   gone by 1983

BTW...I'm looking for old HP Test & Measurement catalogs :)
(Preferably pre-1990)

thanks,
