Tadpole Alpha-Book 1

Not many around (never were).  Since the HW was developed externally, it
will reach a stage where little things like firmware get too out of date.  I
have one in my office, that I occasionally power up (it has V7.3-1 on it) -
I use it when I go to a number of customer sites to bring along my
development environment.

V7.3-1 here

LK411 - Yes (the LK401 is a old serial KB).  It will auto-sense the
connection of an LK411.  The crippled/*keyboard on the laptop was the
hardest thing to get right.

Mine bit the dust a long time ago and always needs to be plugged in.

> Does it run the 21066/LCA4 chip?

Al Meier of HP tells me that this is correct. BTW, he has an Alphabook
running 7.3-1.


> What ALPHA (or VAX) does it roughly compare to in speed?

Al says it's approximately a Jensen (DECpc 150 axp, AKA DEC 2000/300).

Al says you can write him for further info:

According to Al, Fred Kleinsorge also has an Alphabook.

Hope this helps!
