I compared the UK ROM's dated 851120 to my USA ROM's (when living in Europe in 1986). The only differences where minor (tables, not routines) and are listed below. These where the ONLY differences in the first ROM release to Atari owners in the Netherlands and UK versus USA. I seem to remember however that there was a mistake : these differences did not include a 60Hz -> 50 Hz patch, which later ROM's do have (?). address USA ROM UK ROM Comment $FC001D $00 $07 config byte $FC205F $5C $23 keytable \ -> # $FC2094 $00 $5C \ $FC20B7 $40 $22 @ -> " $FC20B8 $23 $9C # -> u.k. pound $FC20DC $22 $40 " -> @ $FC20DD $7E $FF ~ -> _ $FC20DF $7C $7E | -> ~ $FC2114 $00 $7C | $FC215F $5C $23 \ -> # $FC2194 $00 $5C \ This shows that - at least for the first ROM release - differences are minor and only related to tables. Not to addresses of data or code. Gert Slavenburg (UUCP : ..!pyramid!prls!gert)
