There are currently shipping restrictions imposed due to the
SARS-CoV-2 pandemic which may lead to delays of shipments
outside the European Union.
The current C-One board is sold with the Minimig Extender mounted.
We don't sell the Minimig Extender separately, if you wish to
purchase it, please contact
ATTENTION! Please make sure to read the
disclaimer at the bottom of this page
before placing an order! The C-One is a fine piece of hardware,
but it's certainly not the computer solution for everybody.
Everything is in constant flow due to the ongoing development,
please keep this in mind.
What it is:
The C-One computer is an enhanced adaptation of the Commodore 64 - the most
sold of any computer model (Guiness book of World Records). While retaining almost
all of the original's capabilities the C-One adds modern features, interfacing and
capabilities and is a sorely needed fill for a gap in the hobbyist computer market.
The C-One is a motherboard ready to mount into an ATX style computer case
(board dimensions: 272 mm x 190 mm).
The ports will match the holes of the case, except for the audio connectors, which do
not fit without mechanical modification of the case (holes have to be drilled).
Connectors on the C-One are ATX style. The C-One board is designed for an
ATX power supply and accommodations have been made to keep the machine as
'laptop/portable capable' as possible, such as startup of the machine from two
voltages only (3.3V and 5V), and diskless operation.
3.5" floppy drive connector with 1581 emulation (using PC drive) with 64k
Capable of supporting MFM 720/1.4/2.8 capacity drives via software
IDE Interface with DMA support
In the initial release these interfaces will not have any support software
(with the exception of 1581 emulation).
Compact Flash Media Slot
TTL level digital video interface (for example to drive an LCD screen)
C64 compatible Cartridge Slot
Up to two PCI connectors (factory-stuffed only one)
Capability to configure C1 system chip settings externally
Two Amiga 1200 compatible clock-ports for expansion
PS/2 Keyboard port with either Commodore 64 matrix emulation
(configurable) or raw data access
Joystick lines can also be emulated via keyboard
PS/2 Mouse with 1351 emulation and bi-directional communication support.
IEC Serial Connector supporting Commodore VIC/64/264/128 drives and
2 Joystick Ports (Paddles supported with classic SID chips installed)
PC-style DB25 Parallel port (can act as C64 userport with adapter)
- ATX case and ATX power supply
- CompactFlash memory card
- PS/2 keyboard
- SVGA-capable monitor
The C-One is a developer board. Do not buy it for what it may become in the
future. If you buy, then only buy for what it is right now: A board that will
experience a lot of core changes. You will need a PC to have
access to the internet, because that will be the only place where you can retrieve
new cores. The early startup ROM can either boot from a CD-ROM that you have
written with your PC, from Compact Flash (CF card writer for the PC required!),
or from a harddisk that is connected to the IDE port of the C-One board - this
assuming that the harddisk already contains the necessary files. Be aware that
the C-One cannot copy these files between media at this stage, you have to do
this with separate equipment!
