Re: 7613 Mainframe - Readout problem


Yes, thank you, thank you, thank you.
I just finished reassembling the 7613 mainframe, after replacing the U214 chip (155-0022-00) on the vertical interface board. The board can be accessed from the front after removing the plug-ins.
The readout is now stable and no longer follows the movement of the track on the CRT. The most difficult thing is to reinsert the vertical interface board on the pins protruding from the rear board.

Thanks again, without Roger's help I'd still be looking for the fault.
