I have seen a few of the full-punch reperfs in past years. These printed all characters in between the 
feed holes. Occasionally one would have to use their imagination but for the most part, it was a 
readable situation. 

Model 14 typing reperfs printed across the top and bottom, depending on Upper Case or Lower Case. 
I think that the later 28 typing reperfs did the same. With the chads in place there was never or 
rarely a situation where the print was not readable. 

I have a 28ROTR that I've not yet put into service. It has the chads in place on the short piece of tape 
that came with the machine. That was supposed to be a 'winter project' but it did not come to pass. 

TELETYPE made 'chad collection items' that could be installed and a box into which the chads were 
delivered. The item in the photo shows only a top view and nothing below where the chute and 
collection box would be located. Even with the correct hardware installed, there were always a few 
stray chads that eluded the collection system. 

Thanks & 73,

Enclosed is a picture of a LPR33ARC, fully perforated tape reperf in a M28 ASR. You can see the chad chute and some chad below it. There doesn't seem to be any place for the chad to go. 
This ASR came from Jack, W2TTY (SK), so he may have installed the LPR33ARC in the ASR cabinet. 

Have fun
