The following patch information applies specifically to revision 0111 of the DSKY board.
Looking at the front of the board, you should see "0111" in the the upper right corner.

NOTE: Both of these issues can be worked around in the ROM software.  You may wish
to check your BIOS source to see if it has options to correct these issues before
making hardware modification.  Specifically, BIOS_062511 has this option.

Refer to the accompanying file DSKY Rev. 0111 Patch.jpg for a picture of the patches.

Patch 1
-------

This patch corrects pin 1 of RR1.  It will reconnect pin 1 from +5 to ground.
Referring to "DSKY Rev. 0111 Patch.jpg", on the back of the board, cut the
two traces that are circled.  Specifically, these are both traces that
connect to pin 1 of RR1.

- Add a patch wire from pin 2 of JP1 to pin 3 of K1.
- Add a patch wire from pin 1 of RR1 to pin 1 of K1.


Patch 2
-------

There has been variation in the bit that is set for the top row of keys in
various incarnations of the DSKY.  More recent versions of the software expect
bit 5 to be set, but the hardware is wired to bit 6.  This patch will cause
the top row to set both bit 5 and bit 6.  At present, having both bits set
is not a problem for the software.

- Add a patch wire from pin 19 of P1 to pin 21 of P1
