Floppy disk emulator

Atari
- Atar 810: 6507 CPU + WD1771 schematics
- Atari 1050: 6507 CPU + WD273 schematics
Commodore
- 1541: 6502 CPU + custom hw schematics

dumb ones are easier to do, sample solution: CocoSDC (2 CPLD, 1 FLASH, 1 ATmega MCU)
a generic solution for the smart ones is to connect it to a PC through USB/RS232/Parallel, (SIO2PC, X1541, …)

homebrew
compiler
debugger 1 homebrew: brew install open-ocd
debugger 2 homebrew: brew install stlink
IDE installation guide
- install eclipse c/c++
- install all gnuarm plugins: http://gnuarmeclipse.sourceforge.net/updates
- install “GCC Cross Compiler support” and “GDB Hardware Debugging” from: http://download.eclipse.org/tools/cdt/releases/kepler
- new C project will have an option for “STM32F4XX C/C++ Project”, defaults are mostly ok, you have to point to the arm toolchain in the last step!
integrate a debugger provider (optional):
- add new external program (green play icon with red toolbox)
- Location: /usr/local/bin/st-util
- Working Directory: ${project_loc}
- this will just run that tool, you can do it on the command line, it will print the default port for the gdb server
integrate debugger
- Debug Configurations (under Run menu)
- new
- on the Debugger tab set the path to gdb in the arm toolchain
- JTAG device: generic tcp
- port: 4242 (default for stlink)
