No earlier revisions (TDS694B etc) appear to have been released.

These scopes contain ICs in the triggering system that are known to fail, commonly understood to be for thermal reasons. Three ICs are present: Ch 1/2, Ch 3/4, 'Other' (ext trig?). The ICs appear to have poor thermal contact with the PCB; when failed, the scope will no longer trigger on the relevant channels (however, signals will still be acquired). It is possible to transplant these ICs with standard SMT hot-air rework equipment. The 'Other' IC has been used as a donor in some cases.

Do not operate this scope without the case on, WITHOUT extra cooling means.

The low (by modern standards) memory length, coupled with the high sample rate of this scope, means that it is best described as a 'one-shot' (or 'transient') digitizer. At the fastest sweep (100 ps/div), only 3 μs of data can be captured with the standard memory allocation.
