@ -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:
* 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, 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. Root cause identified, tentative fix identified and (optionally) applied.
* 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.
