Next-generation Z80-based retro computer system
Documentation
For documentation, please take a look at the Wiki.
Abstract:
What would the Aquarius have evolved into if Mattel hadn't abandoned the system back in 1984? The Aquarius+ is the next-generation of Z80-based 8-bit hardware for the Aquarius platform. The intent is to deliver a cost-effective, backwards-compatible retro computer system that both developers and nostalgists will love and use, all in the spirit of the original, orphaned Aquarius platform.
Features:
- Backward compatibility with existing Aquarius hardware and software
- Modern, flexible video solution that supports bitmapped graphics, sprites, and tiles, delivered through clean VGA output
- Dual AY sound chips (virtual) for six sound voices
- 512kb of paged RAM in four 16k banks
- Reworked SYSROM and programmable CHARROM
- Integrated SD card and commands (remove dependency on cassette loading)
- WiFi connectivity
- Bluetooth connectivity for modern game controllers

Questions
How big is the Aquarius plus PCB?
It measures 128 × 83 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Aquarius plus use?
124 parts, built around the XC6SLX9-2TQG144C, Z84C0010AEG, ESP32-S3-WROOM-1-N4R2 and TF-03A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Aquarius plus KiCad files?
From the fvdhoef/aquarius-plus repository on GitHub, at the commit this page was made from: the board is System/pcb/mini/mini_rev0/aquarius-plus.kicad_pcb and its schematic System/pcb/mini/mini_rev0/aquarius-plus.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Aquarius plus design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
