Olivetti M10 ROM patch

The stock Olivetti M10 isn't compatible with REX or any M100 Option ROMs.

However the hardware is nearly identical to the M100/T102, except for the keyboard (mainly).

In order to accomplish 2 things

  1.  make M10 compatible with M100 ROMs
  2.  make M10 compatible with REX#

the Tandy 102 main ROM was patched to work (reasonably well) in the M10.

Use the patched M100 Main ROM in M10 by burning a 27C256 eprom and mounting it in the M10.

Initial version, V2, is available here: http://club100.org/memfiles/index.php?direction=&order=&directory=Steve%20Adolph/Patched%20M10%20Main%20ROM&

A minor bug was observed, leading to V3, which is available here:
