Hmmm I'll double-check, but I thought I had.
Is "0" a proper value for the I register to avoid the effect? 'cause that's what I'm using. I guess it is, the ROM is not contended...

Set the I register to 25. This is within ROM and Legal. When I is set to 25, due to the ROM values of (25*256+255) and (25*256+256) ie. the Word at 6655, a call is made every interrupt to 23842, where i place a JP to your interrupt routine. -
