Specs for the Iwin Cleveland M:

CPU: Motorola M68060 / 50 MHz (M+ version with M68060/66)
Motherboard form: ATX - standard PC
Memory: 4 memory slots for standard SDRAM/DIMM memory modules. (max. amount of RAM 128MB in sum)
Memory management: Done by MCU (memory control unit) and DDK-I (DDK-internal) to separate memory into chip and fast ram. User can select the desired amount of usable and available memory with the DDK-I user interface before the boot process during startup
Memory expansion: User can expand the memory using standard SDRAM modules. Computer has to be restarted and DDK-I has to "count" the memory once more after installation.
i3D graphic subsystem: NOT as in REVA stated integrated on the motherboard! The i3D card will be connected to the motherboard through a special connector on the very right side of the board (see new suggestions for the board layout). Graphic chipset with the i3D chip on top of it. Switcher2 included on the board for correct calls from the AmigaOS and correct display of the Amiga graphic modes as well as the different chipsets of the original Amiga.
i3D specifications (see below)
Iwin DDK software included on a single chip on the motherboard to provide maximum compatibility with new hardware (supported by the DDK-I software)
NCU Chip on board (Network controlling unit) which acts as an Ethernet NIC together with the 10/100 interface
PAT Chip on board (Interface controlling unit) which handles the connections between the various interfaces (USB, etc.) with the motherboard and then the DDK-I chip
IDE Controller on board (Cleveland) and standard SCSI2 / UW controller card in Ockna (acquires one PCI slot!)
Cleveland IDE controller can support up to four EIDE drives
BOOT ROM chip on board which handles the boot procedure, checks for the AmigaOS, invokes the DDK-I setup if needed.
Switcher1 chip on board which handles most of the compatibility issues between the Iwin motherboard and custom chips and the original Amiga custom chips, extensions, etc. Switcher is (c) by Iwin.
SHU (Slot handling unit) chips (2 x) on board. They handle the different slot architectures on the motherboard to provide compatibility with PCI and AGP with the AmigaOS and the Zorro slots with the Iwin custom chips
BON Chip on board which handles the connection(s) between the Switcher and the expansion slots as well as the video slot for providing high compatibility with existing Amiga hardware
3 x PCI slots on the motherboard
1 x AGP slot on the motherboard
3 x Zorro III slots on the motherboard (subject to change!)
Video Slot on board for use with existing Amiga video / multimedia hardware
1 x Floppy HD 3.5"
Harddisk included (4, 8, 10 or 13 Gigabyte)
Keyboard and Mouse interfaces included on the board for connecting original Amiga keyboards and mices (mouse connector on external cable).
2 x USB interfaces
1 x parallel interface
2 x serial interface
2 x digital joystick interface (on external cable)
1 x analog joystick interface (on external cable)
TV in/out interface
Analog and digital stereo input/output interface
