What John stated + propaganda by Intel showing DEC what they were 
expecting to achieve in 3 years on X86 really scared DEC mgmt. 

Btw, Intel to this day not reached the CPU Ghz numbers they were 
pitching back then.

Let's not forget where a significant boost in X86 performance came from
(Alpha inside) and that was the reason for the lawsuit which Intel lost.

Bottom line, like a card game, Intel bluffed with what they had and DEC 
blinked. 

Imho - At some point in the late 80's timeframe, DEC mgmt. did not know 
what kind of company they wanted to be when they grew up. 

Hence, they sold key SW products, then sold key HW prod's, then the board 
and C levels threw their hands up and decided to line up at the trough for
big bonuses by selling the company.

At the time of sale to Compaq, DEC had $3B in the bank which was approx.
30% of what the sale was for ($10B). No doubt the fire sales leading up to
the final sale were meant to sweeten the selloff.

Ahh well, water under the bridge .. this type of corporate shenanigans
Is common place today.

For another view of DEC mistakes-
http://www.sigcis.org/files/Goodwin_paper.pdf 
" In 1987 Digital Equipment Corporation (DEC) was the number two 
computer manufacturer in the world with its founder being named the 
“‘most successful entrepreneur in the history of American business” by 
Fortune magazine. This paper looks at the later history of Digital Equipment 
Corporation and asks how an organization that was so successful in 1988 
could sink to become a takeover target for a PC hardware company ten 
years later."
