Zilog also have a C compiler. What Debug solution do you use ? This website http://www.statlab.uni-heidelberg.de/projects/oberon/ says ["If you cannot avoid C, use o2c, its successor OOC, or Ofront to convert Oberon to C."] - so there are some C pathways. and this is low cost, and supports Z80 and Rabbit http://users.iafrica.com/r/ra/rainier/pz180.htm#Embedded Pascal Z180 area -jg

The Whatever-to-C translator and the C cross-compiler (sdcc) run there. The resulting binary is to be burnt into an EPROM and run on the target Z80 system. I do not intend to run FNU/Linux, the Whatever-to-C translator or the cross-compiler on the Z80. Philipp

Move to something like an ARM, or any other well-supported 32-bit architecture, and you will have a very much easier time experimenting and learning. Once you have something that has good gcc support, you've got C, C++, Ada, Objective C, Fortran, Pascal, Forth, and D ready to try (libraries and debugging might be issues). You also have enough power to use scripting languages like Lua. The Z80 was a nice architecture in its time - but that time was about 20 years ago.
