Repositories

All sources for steckOS, BIOS, firmware, decoder and also schematics and layouts can be found in our repositories at bitbucket.org:

All software (steckOS, BIOS, libraries, tools, games, stuff): https://github.com/Steckschwein/code

Hardware (Schematics, PCB Layouts, Firmware): https://github.com/Steckschwein/hardware

We almost exclusively use Open Source-Software to design and code for the Steckschwein.

cc65 Extensive suite of cross development tools for almost every 6502 based platform. We mostly use ca65 because of the linker. Also, we have a few tools written in C.
KiCad The best OSS EDA suite. We use it for all things hardware.
Acme Very nice 65xx crossassembler for almost every platform. We used ACME in the beginning, but moved on to ca65 from the cc65 suite. We still use it for quick-and dirty stuff.
GALasm Our GAL-based address decoding logic and our wait state generator logic are defined using GALasm, which is an ancient tool, but still very useful.
Xilinx ISE Xilinx ISE design suite to program the XC9572. The only non OSS development tool we use.
py65mon We use it’s 6502-emulator/simulator for automated testing using unit tests.
