Progress on PCPI mode bug fixes. PCPI mode is now working again, but the config interface is still broken enough to prevent the use of the config utility while in this mode.. Sending the FORMAT command from the monitor rom returns the card to defaults.
Replace n with the slot number the card is installed in:

]CALL -151
*CnF0:46 4F 52 4D 41 54 00 00

Correction of mousetext / inverse / flashing handling on IIe
see https://github.com/V2RetroComputing/analog/issues/3

  $A0: Amber
