The TDS754C&D and TDS784C&D series are nearly identical, differences being front-panel cosmetics and the presence (754) or absence (784) of a few capacitors on the acquisition board. The only other difference is the position of instrument ID jumpers, also on the acquisition board. In fact, it is entirely possible to convert a 754 to a 784 (see above Links and the TDS784 page for more information).

Note that in the TDS700D series, the acquisition board variant is important — the CPU Board with Firmware 7.xx cannot be used together with the old acquisition board, and the CPU board with old Firmware 6.xx doesn't run with the new acquisition board. The fact that the CPU board has part number 671-4349-00 is by itself not a reliable indication of a compatible firmware version.
