An internal jumper allows the user to select the source of the on-screen readout in timing diagram mode, which can be either the mainframe readout supplied by the 7D01, or superimposed by the DF1/DF2. The latter is the standard setting and allows the DF1/DF2+7D01 combination to be used in mainframes without readout, e.g. the large-screen [[7603N]]. | An internal jumper allows the user to select the source of the on-screen readout in timing diagram mode, which can be either the mainframe readout supplied by the 7D01, or superimposed by the DF1/DF2.

The DF1/DF2 has no direct connection to the scope mainframe | The DF1/DF2 has no direct connection to the scope mainframe − it attaches to the 7D01 through a 50-pin [[D-sub connector]] on the right side panel only. The DF1/DF2 and 7D01 are mechanically coupled by three nylon standoffs that slide into cutouts in the 7D01's case rails. The bottom two standoffs are fixed and are inserted first, then the connector is plugged in and the third, sliding, stand-off at the top is moved to its locked position. | ||
The DF1/DF2 is built around a [[Motorola 6800]] microprocessor with two (DF2: three) 2K×8 masked ROMs and sixteen 1K×1 SRAMs ([[Intel 2102]]). | The DF1/DF2 is built around a [[Motorola 6800]] microprocessor with two (DF2: three) 2K×8 masked ROMs and sixteen 1K×1 SRAMs ([[Intel 2102]]). | ||
