Some symbols still can be added to this input regime definition:

character 187 (ordfeminine)  can be defined as \ordfeminine
character 188 (ordmasculine)  can be defined as \ordmasculine
character 202 (no-break space)  can be defined as \nonbreakablespace

And some definitions can be changed:

character 163 can be defined as \textsterling instead of \sterling
character 192  can be defined as \questiondown instead of ?`
   (ligature ?` doesn't always work).
character 193 can be defined as \exclamdown instead of  !`
   (ligature !` doesn't always work).
character 214 can be defined as \textdiv instead of  \mathematics\div
character 182 can be defined as \mathematics\partial instead of
    \mathematics\delta (this character is described as:
    0xB6 partialdiff 0x2202 PARTIAL DIFFERENTIAL
    in the Apple Computer's definition of  Mac OS Roman character set,
    see the file ROMAN.TXT in the Public/MAPPINGS/VENDORS/APPLE
    directory of ftp.unicode.org . Symbol 'delta' can be found in Mac Symbol
    and Mac Greek encodings).

I corrected Adam T. Lindsay's regi-mac.tex file (see the attachment).
Also I changed input characters to their codes -- it seems to be more
reliable.
