MAIN and MEDIA
A CoCo-compatible MC6309 host, with a separate proposed MC6309 role for media processing.
THE FLAGSHIP / IN DEVELOPMENT
SuperCoCo. The Color Computer that might have come next.
A next-generation FPGA Color Computer, designed for cycle-accurate compatibility with its roots and room to explore new graphics, sound, storage, and connectivity.
Development status: RTL and board-interface verification are in progress. SuperCoCo is not yet a finished product, available to order, or validated for all advertised targets.
ARCHITECTURE / MULTI-CORE CONCEPT
Many processing roles. One coordinated system.
SuperCoCo starts with a CoCo-compatible MAIN processor, then explores a bigger idea: separate MC6309 roles for MEDIA, TASK0 and TASK1, coordinated through a central scheduler, GIME and SD-card block. The concept also places a management MCU alongside the shared system services.
Stew's working architecture sketch connects those roles to audio, video, SDRAM and physical I/O. This is the proposed division of work, not a claim of validated multi-core execution, completed hardware or operating-system SMP support.
TASK0 and TASK1
Two additional MC6309 processing roles in the concept, connected through the central coordination block.
Shared services and I/O
Scheduler, GIME, SD card, management MCU, SDRAM, video, audio, UARTs and peripheral interfaces.
HARDWARE DIRECTION
Thoughtfully engineered, not rushed.
Two form factors are being explored: a board for a CoCo 3 enclosure and a Mini-ITX-style motherboard. These are proposals, not shipping SKUs.
Our priority is to close the RTL, prove the external interfaces, and build a machine that earns its place on the desk.
SOFTWARE RESEARCH
NitrOS-9 and the next step.
We're researching how NitrOS-9 might use additional processing resources through coordinated services and potentially more ambitious operating-system work. Shared-memory multiprocessor support is a research question — not an existing release or upstream commitment.
We're also developing a companion emulator as part of the exploration and compatibility effort. Public downloads will be announced after the appropriate verification and release review.
No pre-orders or deposits yet. We will share manufacturing and reservation details only after engineering validation and realistic production planning.
FUTURE HARDWARE / YOUR INPUT
Which SuperCoCo would you put on your desk?
We're exploring two board shapes. Your vote will help us understand preferences, but it isn't a reservation or a promise to produce either version. No account, email address, or payment information is needed. The poll uses a small anonymous cookie so a browser can change its vote.

Be among the first to see SuperCoCo take shape.
We're not accepting pre-orders, deposits, or payments yet. We'll announce reservation details when design validation, production planning, and support arrangements are sufficiently mature.
