Get the model number and I'll be able to tell you what you can and can't accomplish with it. It will be limited, but with repatching between operations and depending on how many tracks you want to record at a time (can you answer that pls?) you may be able to get by.
Ultimately if you want to have completely undependent monitoring facilities for tape deck outs as well as sources and flexible routing to the tape deck AND control surface switching for quick reconfiguring from tracking to mixdown you will want something different.
Tascam M-30, M-35, M-308 and M-1508 are all great 8 x 4 options for this from the Teac family. Relatively affordable, good sounding and feature-packed as well as not being gihugic in size. Expect an M-1508 to be needing the least TLC at this point. IMO the M-308 is tops out of that bunch in terms of sound and features.
Lots of other options from other manufacturers too. I'm just most familiar with the Tascam offerings and they are relatively plentiful on the used market and have good user community support.
