Does this include a trap handler for the 68881 that catches those '020/'030
floating-point ops and executes them on an 68000??  If so, could you explain
a little more?  Or is there anyone out there who has this (or any other such)
software on-line or in electronically readable format and could email me a
copy ???  Thanks VERY much!!
