Re: Very impressed with free (!!!) Astrobe for RISC5 FPGA

There's also some useful information in Chapter 14 Building and maintenance tools of the Project Oberon book which is accessible from Astrobe for RISC5 > Help > Project Oberon.

Re: Very impressed with free (!!!) Astrobe for RISC5 FPGA

Thank you for your positive feedback. It is very much appreciated.

We haven't released the tools that we use to create the disk image but Andreas Pirklbauer, one of the other guys who has modified the OS has. You can find them at:

Re: Can the limit on the number of record extension levels be increased?

We've just released v7.2.0 of Astrobe for Cortex M3 . Following your suggestion we have introduced a compiler option 'Extension levels' on a new Tools > Preference > Compiler tab page.
