Summary:Sources of such information, including user clubs

Many thanks to Jay B. Harlow for posting his discoveries on the HP-42S.
Most of what Jay describes has already been covered on
comp.sys.handhelds, on the HPHH echo in FidoNet, and in user club
magazines, but there are always new readers who have not seen the
earlier postings, so there is no harm in posting again.  My point in
writing this is to tell keen HP-42S users that the most recent issue of
the journal of the Danish user club has an article IN ENGLISH on just
these HP-42S topics.  XFCN is explained there as a command to execute a
machine language function which the user can enter direct into RAM with
the debugger.  I submit a list of user club addresses to this area from
time to time, maybe the arrival of the HP 48SX and the subsequent
increase in interest in all HP handhelds means I should submit an
updated address list again.  Might I ask anyone who knows of new clubs
or of address changes to send information to me personally, and I shall
post an updated list on comp.sys.handhelds in about a week?  Some users
of electronic mail and bulletin boards feel that the Guthenberg
technology is best left to die - but I feel that both technologies have
their uses - a club journal is much more useful on a plane flight or a
train ride than is attempting to download and read a bulletin board
article under those circumstances.
