Gil,

I'm a recent subscriber to the list, and in fact my history with 
"real TTYs" starts and ends with ASR-33s pretty much back in high 
school, so I guess I'm a "GreyKey"er.  But anyway...

You asked for information on the DEC modified ASR-33.

It was marketed as the "LT33", and was in fact modified by DEC to 
activate the reader.

The following Web site has LOTS of useful information about PDP-8s 
and their interfacing, including these gems:

Teletype Model 33 Line Set wiring printouts

DEC LT33 Teletype Modifications Print Set

The main site: <http://www.chd.dyndns.org/pdp8/>

Scroll down to see the links to the print sets.  They're TIFF files, 
and *LARGE* -- upwards of 6 MB each.

Hope this helps!
