Not B12 which is what you're asking about but I can help out with Black Dog equipment from that time:

amiga 1200 running Dr T's KCS.

akai s950 (TR505, TR626, TR909 etc samples, pitched)
oberheim matrix1000 
yamaha dx7 
roland sh101
roland tb303 

boss dr.rhythm dr-55 
roland tr808

alesis midiverb 2 

yamaha ns10m monitor 
studiomaster 16:8:2 desk 

BTW Bytes is my all time fav album from that era, melodic Uk take on the early Detroit techno sound. I still cane that album now and again
