Teletype also introduced a more expensive ASCII Model 35 for heavy duty use, whose printer mechanism was based on the older, rugged Model 28. The basic Model 35 was mounted in a light gray console that matched the width of the Model 33, while the Model 35 ASR with eight-hole mechanical tape punch and reader was installed in a console about twice as wide. The tape reader was mounted separately from the printer-punch mechanism on the left side of the console and behind it was a tray for storing a manual, sheets of paper, or other miscellanea. To the right of the keyboard was a panel that could optionally house a rotary dial or Touch-Tone pushbuttons for dialing a connection to a network via telephone lines. The printer cover in later units also featured sound deadening materials, making the Model 35 somewhat quieter than the Model 33 while printing and punching paper tapes. All versions of the Model 35 had a copy holder on the printer cover, making it more convenient for the operator when transcribing written material.
