Look at the back of the editor where the power cord enters to locate the nameplate on the machine. 

If the last NUMBER in the TYPE box ends in zero (0), the editor is an older (somtimes refered to as a STANDARD SPEED) editor.

If the last NUMBER is a one (1) the editor is a newer (sometimes refered to as a HIGH SPEED) editor.

In the photo to the left, the editor (701C) is a newer (type 01 ) editor.

In the serial number (Nr) line, the middle four digits indicate the date the editor was manufactured (year and month). In the example photo, the editor was manufactured in January of 1981. The last three digits are the unique machine number.

Whenever contacting The Boston Connection it is very helpful to let us know the TYPE of editor you have as well as the serial number.
