ok more internal pictures. Looks like 7 punches. Does this mean it is a 6-bit (6 data holes, 1 index)?

Subject: Re: [GreenKeys] anyone know the details of this unit?excellent find on that. So I think I'll ask the seller to open the front and try to send a picture, well lit, similar to this picture. And hopefully we can see what this is...
It seems to me that is the best angle to see the punch block.

Subject: Re: [GreenKeys] anyone know the details of this unit?DEC used the BRPE punch on it's Typeset-8 system. They had that knob on the top. See:

Subject: anyone know the details of this unit?See pix. It says "BRPE8 6" from what I can tell. Also, by the connector it appears to be a parallel unit?8 level I would assume, but might it be 6 level with the "6" in the model number?Is it easy for a non-technical seller to remove the cover from the punch block to know more? Does it lift off easily? does it require screw removal?thx
