Subject: Reduced movemap, the keyboard lookup table, from 256 to 128 bytes.
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=3661df2c96f211a81fe9b9a9609c2f4eaa76c8ec;p=FUZIX.git

Reduced movemap, the keyboard lookup table, from 256 to 128 bytes.
The upper half was never used. To make sure, knocked off the top
bit of input characters. Reduces executable size by 128 bytes - but
still not enough for Tormod :-(
