Storage has normal, bi-stable (standard and "fast"), variable-persistence (standard and "fast") modes, as well as independently-switchable reduced-scan mode (to aid high-speed writing) and timed auto-erase. | Storage has normal, bi-stable (standard and "fast"), variable-persistence (standard and "fast") modes, as well as independently-switchable reduced-scan mode (to aid high-speed writing) and timed auto-erase. | ||
The mainframe has the usual analog ch1/ch2/alt/chop/add vertical-mode functions for the two vertical bays, though in the case of the 7934, the two channels are replaced by "left" and "right" to indicate that each mode will slave the vertical deflection to that vertical bay rather than a specific channel. | The mainframe has the usual analog ch1/ch2/alt/chop/add vertical-mode functions for the two vertical bays, though in the case of the 7934, the two channels are replaced by "left" and "right" to indicate that each mode will slave the vertical deflection to that ''vertical bay'' rather than a specific channel. The mainframe provides chop and alt synchronization signals to both vertical bays, which are used by dual-channel plug-ins to switch between the plug-in's channels when ''the plug-in'' is set to alt or chop mode. | ||

Both horizontal compartments are triggerable from either ''vertical'' compartment, through an internal signal path. Amplifier plug-ins with two channels provide a switch to select which channel will be given to the mainframe for routing to the triggers. The horizontal modes (A/B/alt/chop) allow the horizontal deflection to be controlled by either the A or B compartment only, or by both, on a time-sharing basis. The mainframe also provides hold-off signals between the two horizontal, which allows a delaying time-base in the A compartment to trigger a delayed time-base in the B compartment. Both the delaying and delayed timebases can be displayed on the screen at once by selecting the chop horizontal mode. | Both horizontal compartments are triggerable from either ''vertical'' compartment, through an internal signal path.
