The *ONLY* remaining broken bit is that it is ASSumed that output is in
cp437.  Since most of the stock fonts do NOT use cp437, this is obviously
broken.  However, until I start supporting unicode or multiple codepages
correctly, the world will just have to deal with this.

Input will only work if the character entered exists in the cp437 codepage.
If it doesn't, the input is ignored as if it never happened.  However, if
the character IS in the cp437 charset, it WILL work correctly now (cheers)

So, for example, on a Spanish keyboard, everything except the underlined
'a' and underlined 'o' (and the Euro if so marked at AltGr-E) will work
properly.

Thanks for everyones patience on this one... sorry you still can't have
a new build.  :-)
