Bummer, but thanks for checking that.
I don't think there's much that can be
done with the LPFK without
desoldering the 8051 chip and reading out the program. Catch is, the
chip has probably had its encryption table programmed, and probably the
lock bits as well...
I was right.
The 8051 has both lock bits programmed. Zero activity in program mode, all
outputs Hi-Z.
:( Any experienced reverse engineers in the audience, or
IBM collectors with
information / drivers / docs for the LPFK?
No, I wish I did, though. I have two LPFKs waiting for me at home when I
get back in a few months, and I had been expecting that codeninja's stuff
was going to work.
I suspect that if PC drivers are unearthed, it will be a simple matter
to throw a serial analyzer on the line and look for traffic - I'd do that
myself with an HP4951, but, again, that will months from now.
I wish I could provide help, but without hardware, I'm reduced reading
this thread and hoping to learn from it.
Thanks,
