The Dutch group have compromised both, but the main focus is on the
EPROM's since that's a much more fun attack :-) Some confusion there is
likely my fault.

That part of the machine is light-tight when in operation, yes. There's
no seal at all on the EPROM's in the Dutch voting machines, I'm pretty
sure that's the case in Ireland too. There is a seal on the cover which
needs to be opened to access the motherboard and ballot modules, and in
Ireland there is also a seal for the ballot modules.

Oh, there are efforts under way to get MacOS < 8 running :-)
