The PlaySoniq Multi‑Expander adds Sega video, audio and memory features to an MSX computer with configurable PAL/NTSC, SID and FPGA support.
The PlaySoniq Multi‑Expander for MSX is a hardware cartridge that integrates a Sega 315‑5246 A/V chip, a MOS Technology SID, up to 128 Mbit of addressable memory and a Xilinx Spartan II FPGA. It provides real‑time PAL/NTSC switching, configurable memory mapping, and routing of PSG, SCC and OPLL sound through the SID filter, giving up to thirteen sound channels.
The manual explains installation, power‑up, connector usage (a durable 15‑pin VGA‑type connector), software loader options, and how to adjust video, audio and memory settings. Compatibility tables list tested MSX models, and appendices give pin‑outs, overlay codes and utility tools for advanced users.
| Addressable Memory | 128 Megabit (16 Megabyte) |
|---|---|
| FPGA | Xilinx Spartan II XC2S50 |
| Video Encoder | Advanced Devices AD724 PAL/NTSC |
| SID Oscillators | Three independently programmable audio oscillators |
| Sound Channels | 13 total channels (SID + SCC+) |
| Connector | Gold‑plated 15‑pin VGA‑type connector |
The PlaySoniq includes a software‑switchable PAL/NTSC encoder, allowing you to select PAL or NTSC encoding in real time.
Use the Map2mb.com utility to set the mapper to 2 MB per sub‑slot, or Mapoff.com to disable the mapper entirely.
The device uses a 15‑pin standard VGA‑type connector for video and audio output, but it is not compatible with standard VGA monitors.
