It's been a long time since I poked around an original O2R, and I'd forgotten about that limitation which was basically down to the prevalence of 16-bit digital tape formats of the day, which meant that to record 24bit word lengths on those machines you had to use bespoke re-formatting arrangements that split off the lowest 8 bits from some channels, and then dump them into other channels (and recombine them on replay, of course).
However, the desk itself supports 24-bit wordlengths internally, and although I can't specifically remember, it may be possible to work with 24-bit I/O using the original AES cards rather than the TDIF and ADAT ones (if you can find any). It may also be the case that the later console firmware updates allowed 24-bits via the later ADAT cards... But I'm probably getting confused with the O2R96 and the mini-interface cards.
