I am helping a friend to troubleshoot his 130XE computer remotely, I don't have physical access to his computer.
The computer has several issues, broken keyboard membrane and possibly a bad Antic.
But one thing is a mistery to me with this computer: it has several resistors soldered right at the SIO port.
Please see attached picture.
Any ideas what is the purpose of these resistors on the SIO port?
