Retrobits returns with a spotlight on a powerful new upgrade for the Amiga 4000: the Z3660, developed by sHaNsHe of Double H Tech. This all-in-one accelerator breathes new life into classic Amiga hardware. It introduces 16-bit graphics and audio, Ethernet connectivity, SCSI support, and a host of other enhancements.
At its core, the Z3660 combines the classic A3660 design with a modern Z-turn FPGA board. It also features the Motorola 68060 CPU, widely considered the final evolution of the 680×0 CISC architecture. This processor shares several characteristics with the early Intel Pentium and delivers high performance. In its day, the 68060 powered premium systems like the Amiga 3000T and 4000T, as well as the Atari CT60 and CT63.
Unlike many traditional accelerators, the Z3660 integrates both modern and legacy technologies into one compact solution. The board not only accelerates your system but also unlocks new capabilities through its FPGA. Networking, fast storage, and rich media output become possible—all within your original Amiga chassis.
So what does this mean for Amiga users? With the Z3660 installed, the Amiga 4000 can run heavier productivity software and more demanding demos. It also opens the door to modern applications, more complex audio and video work, and smooth emulation. Retro developers and tinkerers gain access to a much faster system without sacrificing authenticity.
The Z3660 transforms the Amiga 4000 from a nostalgic classic into a serious workstation. Whether you’re pushing pixels in Deluxe Paint, tracking music, or experimenting with next-gen Amiga software, this upgrade makes it all possible.
Retrobits dives deep into the board’s features and performance, showing exactly what this powerhouse can do. If you’re serious about modernizing your Amiga setup, this episode is well worth your time.
