Thanks Keith.
I've tested the Vcc pins on all the chips that are on the board and none
show +5. The A500 works without issue so I know the power supply is ok.
I can find +5 on the .100 dual pin header that the memory expander plugs
in to, but no where else. +12V does show up on the molex power connector
for the drive.
I've also checked both sides of what look like tantalum caps and I get no
power there either. I can't see any visible damage to the board, no cut
or scratched traces, etc. I'm at a total loss as to why it's not getting
any power.

I've got a DataFlyer 500 expansion for my
Amiga 500 and it's dead as a
post. There's +5 on the connector but no where else that I can find on the
board. Does anyone here happen to have a schematic for it or know where I
can find one?
tnx.

Gene,
I've got one of those. I haven't seen a schematic. Mine works fine. If you
want to provide detailed instructions on exactly what measurements, etc you
need, I can do them. I also have the installation disk too, if you need.
I'm tied up for the next couple days, but I'll be free after that.
