 Good tip. It's certainly not in the Rainbow site archive and I might have been
able to get my 'bow up and running earlier with a VR241.

 I was quoting one of the 2 reviews Byte did on the "bow. They generally
slagged the Rainbow and were likely possible for part of it's lack of success.
The other part was the DEC executives who never really liked the venture and
saddled it with a bunch of prohibitives so as to not threaten their mini-market
including the PRO and DECMate.

 Well it should be in CC archives and of course I have it in mine. It would be
good to have it on the Swedish Archives however. Hopefully the maintainer who
answered Antonio Carlini's offer of the service manual, will also put it onto
the site as it was a very comprehensive pinout listing.
