The A1200+ is an open-source reimplementation of the Amiga 1200 motherboard, not a complete replacement computer. It is designed around original Amiga 1200 custom chips salvaged from a donor machine, with RAM and video handled on separate boards. The Belgian Amiga Club’s project description also specifies CompactFlash storage connected to the IDE interface. That makes this a project for builders prepared to source parts and assemble a system—not a confirmed, ready-to-buy Amiga.
What the A1200+ motherboard is
Jeroen Vandezande’s A1200+ reworks the Amiga 1200 motherboard from its original schematics. The Belgian Amiga Club project page describes a revised design that keeps the original AA custom chips, which fit in sockets, while changing several supporting components and connections. Hackaday’s July 21, 2019 feature characterized it as an open-source PCB intended as a drop-in replacement for an A1200 motherboard, but “drop-in” does not mean a complete, ready-to-run computer: the custom chips and other system parts are still required.
The keyboard controller is replaced with a modern 8-bit microcontroller. Budgie, by contrast, is soldered directly to the board rather than socketed. The project separates RAM and video from the main motherboard, making those functions dependent on additional boards.

RAM and video move to daughterboards
The A1200+ places RAM on a separate board to allow different memory configurations. Video is also moved to a separate board, which carries Lisa signals and typical Zorro signals. The project page notes the possibility of developing an RTG card, but that possibility should not be read as a claim that an RTG card is included or available.

CompactFlash replaces the PCMCIA slot
The design removes the PCMCIA slot and puts a CompactFlash socket in that area. The project page says the socket connects to the IDE interface, buffered through an otherwise unused Budgie bus buffer. Hackaday’s brief summary described the slot as SD; the more detailed project-authored description specifies CompactFlash, so CF is the better-supported description of the documented design.
No specific card model, capacity, or compatibility list is established. Anyone assembling a board should check the documentation for the exact board revision before choosing a card.

What a builder needs—and what remains uncertain
The A1200+ is not a turnkey Amiga. At minimum, the design depends on original custom chips from a donor machine, as well as the relevant RAM and video boards and the other required components. Hackaday writer Jenny List summarized the donor-chip requirement in 2019: “The catch: it does require all the custom Amiga chips from a donor board.”
Current availability of the exact bare PCB, an assembled board, or a complete compatible parts set is not established. Hackaday’s comment thread included a developer update in July 2019 saying the PCB was still work in progress at that time; that dated update does not establish the project’s present status. Likewise, there is no confirmed price or current stock information here.

For a DIY build, plan to verify the current project documentation and board revision, locate donor chips, and confirm the RAM and video board requirements before ordering parts. The documented storage interface is CompactFlash over IDE, but the available description does not provide a tested card list. A PCB fabrication service and a specialist Amiga parts retailer are possible categories of suppliers; no particular seller or stock status is confirmed.

How it differs from other Amiga motherboard projects
Several projects use familiar Amiga names or cases but pursue different architectures. The important first question is whether you want a board built around original A1200 chipset parts, a newer computer that fits an A1200 case, an ATX hobby build, or a PowerPC platform.

Questions to settle before choosing the A1200+
- Can you source donor chips? The board retains the original AA custom chips; this is not a chipset-free replacement.
- Are you prepared to build around daughterboards? RAM and video are separate from the main board, so confirm the required boards and their availability.
- Does the storage arrangement fit your plan? The project description specifies CompactFlash on IDE, not a documented SD setup.
- Have you checked fit and assembly needs? Verify the case, connectors, board revision, and required parts against current project documentation before committing to a build.
- Are you looking for an original-chipset build or a newer architecture? The A1200NG, AmigaPCI, and Mirari are separate projects, not versions of the A1200+.
