This is a two megabyte memory upgrade for the Commodore Amiga models 500 and 500+. It is a modern replacement for the original A501 0.5MB (512K) upgrade from Commodore. Add up to 2MB of memory to the machine depending on motherboard revision and Kickstart version (see below for details). Can provide both chip RAM and slow RAM in one expansion. |

What's that? In the late 1990s when I bought a used A2386 Bridgeboard for my Amiga 4000, I felt angry that I should have to addinally buy expensive and aged ZIP ram for that card. For 2 mega bytes ZIP RAM I should pay 200 DM (~100 €) !!! {...} I remembered having some old 1MB-PS2-Simms lying around and thought that it should be a possible to use them on my Bridgeboard with only a small adapter. The result of my thoughts and work was that little adapter which can be installed into the free ZIP sockets of the Commodore A2386 Bridgeboard. The adapter is able to provide 8MB RAM which is the official maximum - with a trick also to incredible 16MB! (This needs a BIOS-Update!) |

It is a replacement board solution for the Amiga600, or an Amiga 600 clone if you like this way. Just as Chucky’s ReAmigas for other Amiga models. Primarily designed to replace old rotten boards – and to be honest, A600s are very affected by the leaking issue. {By Róbert Tihanyi in 2022} |

The Retro BB channel presents an Amiga A600 Junior Build, turning a failed A600 into a clean and upgraded machine. The project replaces the original board with a reverse-engineered Junior motherboard and fits it inside a frosted clear case. This gives the system a fresh look while keeping the classic A600 layout. |

Add pixel-perfect HDMI output to the Amiga machines. For all Amiga versions that have a socketed DIP Denise chip, a rather small adapter board can be used to extract the digital video signal (12 bit) to a 40-pin connector compatible with the Raspberry Pi Zero. This can then be used with the RGBtoHDMI software to produce a perfect HDMI picture with very low latency (a few milliseconds at most). |

The Amiga CD32 doesn't output RGB natively. It has Composite, S-Video and RF. The internal ICs have RGB inside we can tap into. {...} All the RGB mods I personally make are called the CleanRGB. It aims at correctly fixing the console itself to output IRE correct voltage level and signals, and the cable is then a pure DC cable with direct connections, no hidden capacitors, sync strippers, resistor or other magic. The benefits of this are pure, perfect RGB signals not affected by your cable, receiver, or noise. |

Some time ago, I had the opportunity to get both an Amiga 500 and an Amiga 1200. While the Amiga 500 was restored as a fairly traditional machine, I had a more ambitious project in mind for the Amiga 1200. My goal was to build three different machines into a single computer: A high-end Amiga {..}, A more traditional Amiga 1200 {...}, & A CD32-compatible system {...} |
