of course I know the bitsavers manuals ... I'm living with them since 
months. I'm not searching docs about the whole PC05, but about the 
mechanical puncher unit inside. The only info about the puncher are 3 
pages in DEC-00-PC0A-D_PC04_Manual.pdf with adjustments instructions, 
extracted by DEC from some original documentation.
I'm searching for an explosive view and disassembly instructions.

The manufacturer of the puncher unit seems to be "Royal Typewriter", 
still in existence. But I found no doc about their paper tape puncher.
