Retro Computing

Summary Perfect diagnostic tool for your Amiga to test memory, keyboard, floppy, I/O devices, Audio, Chipset and some others! Here is a tutorial how to build it! If you are lazy or not interested in the details you can download the binaries here ! Build Amiga Test Kit (on Linux) Needed Downloads: binutils-2.28 ( Link ) gcc-7.1.0 ( Link ) Amiga Test Kit ( Link ) Extract them to a folder in your home directory e.g. /home/user/projects. (tar -xvjf binutils-2.28.tar.bz2, same with gcc) Configure for m68k ../binutils-2.28/configure --prefix=/path/to/install --target=m68k-unknown-elf Makefile will be created. Build with make && make install ../gcc-7.1.0/configure --prefix=/path/to/install --target=m68k-unknown-elf --enable-languages=c --disable-libssp Makefile will be created. Build with make && make install mpfr not found try this: ./contrib/download_prerequisites If everything worked like a charm you have to add the new binaries to your PATH vari

If you have stability issues with your 34 years old Amiga 1000 it's a very good idea to check the output lines of the power supply: +12V,-5V and +5V! Plug pinout: Check with scope to also see ripple and noise or rough with a multimeter!                    Current Voltage      Min.    Max.             Stability        Ripple & Noise ------------------------------------------------------------------------------ +5V            2A         8A               +/- 5%           150 mV P-P +12V          0A         1A               +/- 5%           150 mV P-P -5V             0A          0.25A         +/- 5%           150 mV P-P When it comes out that the output values are too bad you have to replace the old capacitors of the PSU! For this you must disassemble the whole computer due the position of the power supply: I have the Shindengen CA1000PS/EC (PAL Version)!
