The B-series computers have an internal co-processor port as well as
an expansion port.  An 8088 board could be installed internally, rather
simply as you suggest.  You should peek inside- some B256-80 machines came
with the co-processor board standard.  The hard part is finding one of these
boards and/or the software.  

The is a very persevering user group, CBUG, which is into the B-series
computers in a big way.  They have even interfaced them to the 1571 disk
drives which provide them with easy access to CP/M software.  I highly
recommend them.  For information, write:
