Generally speaking, be careful with devices that rely solely on the old FW drivers. Especially if you're on Catalina. Many are/were 32-bit based and the device apps are not updated (therefore not compatible).
The money spent trying to get that older FW hardware working correctly is often not worth the tradeoff. It's cheaper to use a standalone MP4,1/MP5,1 for those needs specifically and transfer the data to the MP7,1. Most FW-based tape decks like DV, DVCPRO/25, DVCPRO50, DVCPRO100/HD are the same. Unless component or SDI outputs are present on the deck, getting them to "work" properly with signal and deck control via FW (not through TB) in Catalina is an abysmal headache since Apple dropped a lot of the native FW tools in Catalina.
