Here are some hi-res pictures of the Commodore MAX machine (aka Ultimax or VC-10), a stripped-down game console variant of the Commodore 64 that was briefly available in 1982.
The membrane keyboard has the same layout as the C64’s.
The sticker on the bottom says “MODEL NO MAX-04”, “SERIAL NO 10816”.
On the back, there is the the power switch, the power connector (same as the C64), a 3.5 mm audio jack, a standard C64 cartridge port, the TV connector with a channel select switch, and a cassette port.
There are two joystick ports, one on each side.
The back side of the keyboard.
The “325565 REV.A” board contains the following major chips, from left to right:
- MOS 6566: VIC-II video chip (variant without DRAM support)
- MOS 6510: CPU
- M58725: 2048×8 SRAM (main RAM, $0000-$07FF)
- MOS 6581: SID sound controller
- MOS 6703: PLA (chip select generator)
- 2114: 1024×4 SRAM (color RAM, $D800-$DBFF)
- MOS 6526: CIA I/O controller
There is no ROM on the board, so all code and even the character set has to come from a cartridge (max. 16 KB) – like on all game consoles from the time. The cartridge can also contain up to 32 KB of external SRAM.
