Steven and Allison,
        I've spent some time today with SDCC and I'm sorry to say I couldn't
find any reference to 8048 in it.  The 8051 yes.  Unfortunately the
memory structure (specifically the banking and jumping) is different
between the 8048 and the 8051.   How about this:  Did they ever
release any sort of languages for the IMSAI 8048 board?

  Rob,
 I think a good place for you to start is with the Small Device C
 Compiler
 ( 
http://sdcc.sourceforge.net/ ) and see if that will fit your
 needs. It
 supports 8048, 8051, etc.. family. Good luck.
 Best regards, Steven

 Does anyone know of any programming languages (compilers)released
 for 
 the intel 8048 microcontroller?
 
 Lookup SDCC, Small Device C Compiler.  Theres plenty of stuff for
 8048/9 family
 and it's cousin the 8051.
