Okay, open sourcers, that does not include Linux. Even uLinux (that runs 
on CPUs without a MMU) should be far to fat for this environment. Hey, 
that thing has even still Banks to access memory, very much like the 
Lotus EMS that we once used years ago on 8086 and 80186. Or in the 
"Language Card" for the Apple II ...

Keil is a company that develops and sells cross-compilers for a host of 
embedded type CPUs. The compiler usually runs on Windows and generates 
binary files that you either flash into Flash chips, EEPROM or via JTAG. 
It's well known in the commercial "community". The KeilC51 costs here 
1600 Euro, and that's just the CA51 Compiler+Assembler. No debugger.


I think that the "No Linux" and "Windows" words in my statemement above 
greatly reduces the chance that people really will jump onto this 
opensource bandwagon. The price tag as well (althought me might be able 
to create a 8051 cross compilation environment on Linux).
