I bought a CP/M version 1.0 with a serial number in the low-five-digit
range, so have some idea of the history.  You had to have been
programming in UCSD Pascal to appreciate the total revolution that Turbo
was at the time.  The major revision I recall between 1.0 and 2.0 was
that 2.0 allowed Dispose() on pointers.  Prior to that, only Mark and
Release were available for heap management.  2.0 also prettied up the
editor--the 1.0 editor lacked commands like ^W, ^Z, ^QE, ^QX.

BTW, even though I have since bought MSDOS Turbo, and upgraded that a
couple of times, Borland *still* send me upgrade offers based on my
original Version 1.0 package.  I can tell by the address.
