Then a bit later it calls the routine pointed by the reset vector (`$3F2`), that is Applesoft's warm restart in `$E003` which in turns calls the `RESTART` routine in `$D43C`. This routine's main purpose is to display the `]` prompt and wait for the user to type a series of direct commands or a line of code. The only way I see we could fix this bug is by pointing the reset vector in `3F2` to a small routine that would reset `$F3` and then call the `RESTART` routine. +When we press `CTRL-RESET` the system does a lot of resets, among them a call to SETNORM (`$FE84`) that restores the `$32` memory to `$FF`.
