From memory, the Blackface has a choice of outputs but any of them will need an appropriate multichannel interface.
I think the basic jacks on the back provide 8 unbalanced outputs which could go directly to any interface with 8 unbalanced line level inputs.
There would also be a big multipin connector (an ELCO I think) which would give the same 8 outputs but balanced if your soldering skills are up to making up a breakout cable--again to an 8 channel interface.
Finally, there should be a fibre optic output which could go direct to any interface with an ADAT in.
(Of course, it's worth saying that if you have an 8 channel interface, I'm not sure what you'd gain by recording on the ADAT then dubbing into your computer...you could just go straight into your laptop.)
