[comp.sources.wanted] xassem, callback... wanted

	Can anyone tell me where I might be able to find any of the following:

	1) A public domain or relatively cheap cross-assembler for 68020?

	2) Public domain program that will call a user back over a modem.
	   (I saw this posted somewhere a while back.  I browsed through
	    the recent index posted in comp.sources.unix and didn't notice
	    anything... maybe I overlooked it.)

	3) Some subroutines/examples of B-tree (B*/B+ trees ok too)
	   implementations.

	Thanks
	Randy
