This is the memory side cards after restoration. The red cards at the bottom is the teletype interface. I have a R401 where the R405 normally is so I can run the teletype interface at 9600 baud. This save a lot of time when I download the diagnostic tapes from a PC. The cable from the W070 at the bottom is the teletype cable. The card was missing so I put a cable on the spare card I had and installed it.
