[comp.sys.amiga.hardware] Flakey AT bridgeboards

WTW101@psuvm.psu.edu (Bill Warner) (09/02/90)

From the first day I bought my AT bridgeboard in May I have had nothing but
problems with it.  This is my second AT board (the first one I got replaced)
and now the problems are appearing again all over.

Basically, when binddrivers is run the janus.library fails to load, or execute
properly.  Half the time it works fine, and half the time it fails.  Also, when
my AT board does boot it will lock up at random, sometimes while booting and
sometimes 5 or 10 minutes into a session.

Has anyone else had similar problems?  Have there been any Janus software
bug fixes since 2.0?  Have there been any AT bridgeboard hardware fixes?  Can
I just return the damn thing for a refund?  I don't want to get stuck with a
$1500 worthless board after my warrenty runs out.  I am taking this board back
to get AT bridgeboard number 3.  Hopefully that one will work.

I have similar troubles with the 2088 board.  When it occurs, I pull off
the lid and reseat the board.  I fhtat fails, I move on to flex the
board and push all the socketed ICs home.  Serious failure mode requires
removing the board and prising up all the ICs and researing them.
I had to go through phase one the other day after I carted the 2000
around in the car - once where I took it, and once when I got back.  It
will run for months w/o touching normally.

Tinned sockets and tinned IC leads are a certain recipe for delayed
disaster (tin oxide is an insulator in this context, and is very tough).
