RE: HP 41C Video interface test. Howto?
Hi,

I tried that with no other modules into the slots and HP-IL plugged into slot 2. Doing every time switch off all and starting the 41 at last.
2 [xeq] [ALPHA] SELECT [ALPHA] [xeq] OUTA [ALPHA]
After that, the 41 says "TRANSMIT ERR"
The same with other ports.
The HP-IL is working as I said, as it was used for the cassette drive (not the printer, which has its own plug)
So you might be right, something is lost into the 82163B, components or program.
I'll try to give a check inside...but I have no eeprom programmer
