I had to program a new batch of micro-controllers, so I decided to make a few minor tweaks to the firmware.
The data invert functionality has been dropped . If you need inverted data, you can use external inverters to accomplish the same functionality. I don’t know of anyone that actually used this feature.
The jumper that used to control inverted data, is now used to control automatic reset and clear. Automatic reset system and clear screen upon power up is now disabled, unless the jumper is inserted. Several Apple 1 owners wanted more authentic operation, so now I disable automatic reset and clear screen feature by default.
A behavior that sometimes caused multiple resets when control-alt-delete reset sequence was used has been eliminated. Once reset occurs, all three keys must be released, before control-alt-delete can cause a second reset. The control-r, control-s, control-t reset functionality is unchanged.
Check out the manual that is downloadable from the PS/2 keyboard adapter page.
