Manufacturer Oliver Achten / Alinea Computer, Germany | Date 2025,2026 | Amiga A2000, A3000, A4000A600, A1200 | - - | Interface Zorro IIPCMCIA | Autoconfig ID 2782 / 16,17,18 |
- Sound Card
- 24 bit sound card with high quality audio output which offers multiple analogue and digital interfaces
- two different card versions available, for Zorro bus and for PCMCIA port
- GUS officially stands for "Great Unbelievable Sound", but can also be read as a reference to the Gravis Ultrasound (GUS) sound cards of the 1990s with superior sound quality
- 32 MB on-board sample memory, clocked at 122.2 MHz
- high-quality digital mixer which operates at full 192kHz @ 24 bit resolution
- 32 channel wavetable engine - featuring per voice:
- 8 /16 bit sample support, 192kHz @ 24 bit mixing rate
- sample start, stop and loop pointer for effective one-shot or continuous playback modes
- 32 bit sample phase accumulators allows fine grained pitch definition
- optional sample interpolation for smooth sounds
- channel independent left / right stereo panning
- hardware ADSR envelope generator
- MP3/OGG/FLAC/WMA hardware decoder (VLSI VS1063), enhanced by a DMA stream buffer
- AHI stream interface, supporting 8 /16 & 24 bit modes for playback and recording
- mixer settings are stored in flash and automatically loaded on start-up - thus working without additional software
- upgradable FPGA core via JTAG interface, or via Amiga-based flash tool
- open hardware, gerbers and FPGA bitstream are freely available on Github (planned for AmiGUS Mini)
- the card does most of the tasks in hardware, which reduces the minimum system requirements
- driver support: AHI, MHI, CAMD (planned)
- AmiGUS
- internal card for the Zorro II bus
- inputs/outputs:
- 1× RCA stereo output, converted from 192kHz @ 24 bit
- 1× TOSLINK optical digital output, supporting 48kHz, 96kHz & 192kHz @ 24 bit
- 3× analogue audio inputs, sampled at 192kHz @ 24 bit: Paula (internal header), CD-ROM (internal header), external source (external RCA input)
- 1× digital output of final mix, to be used as input for other cards
- the minimum system configuration: A2000 with stock 68000 CPU @ 7.09 MHz, 1 MB ChipRAM, 4 MB FastRAM, OS 1.3
- AmiGUS Mini
- external card, connects to the PCMCIA port of A600 and A1200
- inputs/outputs:
- 1× 3.5mm combined analogue stereo and TOSLINK output - analog output converted from 192kHz @ 24 bit, digital output supports 48kHz, 96kHz & 192kHz @ 24 bit
- 1× 3.5mm analogue audio input, sampled at 96kHz @ 24 bit
- minimum system configuration: A600 with stock 68000 CPU @ 7.09 MHz, 1 MB ChipRAM and OS 2.05
- optional case planned

Manufacturer Oliver Achten / Alinea Computer, Germany | Date 2026 | Amiga A600, A1200 | Interface PCMCIA |
- RTG Graphics Card
- FPGA-based RTG graphics card for the PCMCIA port
- provides HDMI display output without opening the case or fitting an internal expansion
- carries both picture and audio over HDMI
- 32 MB display memory, made available through MMU bank switching (systems without an MMU are limited to a 4 MB framebuffer)
- 64-bit hardware blitter rated at roughly 300 million pixels/second
- full blitter and hardware sprite support, plus screen dragging with mode mixing
- reaches performance comparable to Zorro III RTG cards on accelerated Amigas, despite the 16-bit interface
- memory bandwidth: 3.5 MB/s on A600, up to 9.5 MB/s on A1200
- Screen Modes
- 8, 16 and 32 bit color depth
- freely configurable resolutions up to FullHD
- Notes
- HDMI output connector
- driver: P96, developed in collaboration with Thomas Richter
- requires P96 v3.3.0, recommended is ≥v3.6.2
- open hardware, schematics and FPGA bitstream/driver source published on GitHub
- optional injection-moulded case in different colors, sold separately
- expansion requires 68020 @ 14 MHz, 4 MB FastRAM and Kickstart v3.1 - more RAM as well as a faster CPU is recommended
