[cctalk] ASR-33 Help and Parts Needed - corrected message

I was given an ASR-33 complete with stand, reader & punch. This ASR-33 has been modified for RS-232 though a blue perfboard mounted in the connection enclosure (under the cover place where the dialer would be on the right side). It has a DB25 ribbon cable coming off of this board.  The perfboard does not have a label on it that I can find. The ASR-33 also has a 3 x 5 conductor rectangular connector coming out of the rear of the unit with 6 female contacts installed. I was able to connect the ARS-33 to a VT-330+ at 110B 8-N-2 and send and receive on the teletype. The punch seems to work as well. The reader will "chatter" then the reader is put in the start position and the tape out sensor is pressed but the sprocket does not advance and the reader pins to not move. Questions: 1. Why the reader is not advancing and the pins are not activating?  Could this be a read enable contact not being in the active position? 2. What are the pin outs of the RS-232 DB-25.  Other than TX, RX and GND 3. What are the pin outs of the 3 x 5 rectangular connector. I think this is the current loop and other control signals. Does any one of the items below for sale or have a 3D model I can print: 1. Roll Paper spindle (the spindle that the roll paper spins on) 2. Paper Tape Punch Spindle (the spindle that the paper tape spins on) 3. Paper Tape Chad feed tube 4. Paper Tape Chad Box I will be connecting this to either a PiDP-8/I or a PDP-8/E for now and eventually a PDP-8/L Thank you,      Mike
