[rescue] OT: Dead Personal Iris 4D/35 :(

[Corda Albert J DLVA]

The serial port is uses the standard EIA interface which was
in widespread use _long before_ the PC appeared on the horizon.
Have you tried configuring the terminal for no (or software only)
handshake, and using a minimalist cable (i.e. only pins 2,3 and 7
connected)?

You should also try the following:

  1) Try to boot over the serial terminal with the PI's keyboard
     disconnected (although you should have still seen some
     serial diagnostic messages even with the keyboard connected)

  2) Disconnecting all peripherals (except, of course, the terminal :-)
     such as hard disks, etc.

  3) Reseating all boards, cables, socketed chips, SIMMS, etc.
