Those retrace lines are likely an artifact of the brightness control being set too high. It's pretty typical with older monochrome TV sets. It also looks like there's insufficient vertical sweep, probably due to old capacitors. On a CRT that small, I wouldn't be concerned about direct fitting the

UniBone - access DEC PDP-11 UNIBUS under Linux

Guys, I'm about to finish another project: "UniBone" - a Linux-to-UNIBUS bridge, based on the BeagleBone Black. It is supposed to be a development platform for device emulation. At the moment it can emulate memory, emulate an RL11 controller with 4 RL drives attached, and act as UNIBUS

Just picked up an IBM System/36 5362 tonight. It is in pretty good physical condition with just a few minor scratches - other than needing a thorough cleaning. It has 2 60 MB hard disks in the unit. Not sure of the RAM capacity. Missing the the mode hard key. A few of us tried to get it
