Not exactly that, however, i may have something for BB-IV but i think 
these ones used cpu's developed by basic four. I have one 14" harddisk 
from a model 210 as well as a disk pack for a basic four 510, both 
should be bootable. I have the machines/drives as well but not yet tried 
to fire them up. The 210 came with a tape 1/4" drive but i dont have any 

I also thought about writing an emulator but i have not yet found the 
manuals for the cpus used (1300 CPU Technical Manual / M1300 Series CPU 
Organisation and Description Reference Manual). I have scanned the 
available documentation and it is saved at Al's bitsaves site (pdf/mai/).
