HP86 problem
A festive greeting to all.

HP86 problem

I purchased an old HP86-B as the first known problem that the text of the screen is missing to the left of about 7-8 characters, and to the right of another 10-11 characters.

I connected the video output to the RCA input of a TV (MultiSistem NTCS-PAL-SECAM Etc)

as a second problem the system displays both the characters from the keyboard, but any command is rejected with "Error 88 SMT Bad"
example "3 + 3" instead of answering 6 gives me the same error
"Error 88: BAD STMT"

it appears that the correct operating system is not present
By pressing the "test" button the computer performs the test correctly.

But I can't get him to digest anything
