Ping Aussie: GA-7VA question

Aussie, on your reply to a recent post by Rob about the 7VAX you mentioned
you had your Barton 2500 running at 2200on a 7VA, is it the early rev board
with the 3 position clock selector or did you unlock the cpu with the wire
trick on the board in the socket or under the cpu between the pins? I have a
later rev 7VAX and you can only select 100 or Auto so it's wire trick to
unlock or nothing. I haven't bothered yet but am curious if you did and
which method you used if you did.
Thanks
Mark
