@ -24,6 +24,6 @@ Only one version of the 500 ROM is known to exist:
There are at least three significant compatibility bugs in the 6.0 Franklin ROMs: There are at least three significant compatibility bugs in the 6.0 Franklin ROMs:
* With 80-column/enhanced firmware active, once MouseText is activated (via outputting $1B), attempting to turn it off by outputting $18 fails. This affects both the 2X00 and 500. Root cause identified, fix identified, and (optionally) applied.
* With 80-column/enhanced firmware active, horizontal cursor position must use `OURCH` ($57B) not `CH` ($24). This affects only the 2X00. This is documented by Apple, but real Apples, the Laser 128, and Franklin ACE 500 all support using just `CH` via clever firmware routines. Root cause identified, fix found in the 500 ROM and (optionally) applied to the 2X00 ROMs. * With 80-column/enhanced firmware active, horizontal cursor position must use `OURCH` ($57B) not `CH` ($24).

Root cause identified, fix found in the 500 ROM and (optionally) applied to the 2X00 ROMs.
* With 80-column/enhanced firmware active, sending bytes $40-$5F through C3COut1 will appear as MouseText, whereas on real Apples they are mapped to inverse uppercase. This affects both the 2X00 and 500.
