How separate an Apple II+ keyboard and its encoder board ?

["Kallikak" <ken.wessen@gmail.com>]

Subject says it all really.  I just got a second II+, and the keyboard
looks in great shape.  I was hoping to use it to replace the dodgy
keyboard on my Europlus. However, when I plug it in, the power light
comes on, but other than that it's completely dead.  So I wanted to
have a look at the eoncoder board, and maybe swap encoder IC - or just
the whole board, but I can't figure out how to remove the plastic clips
that hold the two together.

Also, this new II+ is not working - lo-res-ish sort of garbage on
appears on the screen, and there is no beep. My first thought was this
was could be due to a faulty ROM or CPU, but these are both OK, so I'm
not sure what the problem is.  Not reseting for some reason?  I suppose
I'll have to try and check the reset signal - I bought a logic probe
for the purpose, but since I only collected this last night, I haven't
had a chance to starting really working on it other than a bit of chip
subsitution first.  I'm thinking that the lack of beep etc means it's
failing to early to be a RAM problem.  Any thoughts on where I should
be checking?

Thanks,
