The speaker was replaced with a larger one, with a volume control on the back. The entire hardware is missing and the case is not designed for this.

PC-type joystick port on the motherboard, right to the serial ports.

There are prepared connectors on the motherboard to allow up to 8 MB of total RAM with 1 MB modules.Д«eside these obvious features, there are other leftovers that didn't made it into the final unit: The onboard memory consisted of four 30-pin SIMM sockets, expandable up to 16 MB of RAM. The header pins would be needed to be soldered in to enable this 'feature'.

The board also has holes for a feature connector of the graphics card to allow the SVGA graphics to pass-through to cards like MPEG accelerators or TV tuner cards. Despite the silkscreen on the motherboard, 41464 chips are not very useful, since the total amount of video memory would be 320 KB. The SVGA graphics memory can be upgraded to 512 KB by using two additional 1 Mbit chips (most likely two chips of the 414256/411000 variety with 20 pins).

Original Adlib cards and clones always use a fixed IRQ and port address. One can change the IRQ of the card between IRQ2/3/5, though an Adlib card normally doesn't make use of it. Whether or not the Mega Drive can make use of this connector is unknown. The only connection between the Mega Drive and the PC itself is the Yamaha FM sound chip that can be used as an Adlib-compatible sound card, including a 15-pin connector for a traditional analogue joystick or MIDI interface. Two ISA connectors from the ISA riser-card are 16-bit, although one is reserved for the Mega Drive itself, which uses an 8-bit connection. The ISA bus/memory controller, combined floppy/hard disk controller, multi-I/O controller and SVGA chipset are entirely made by WDC. The hardware of the PC part is a design entirely based on a chipset from Western Design Center, the same company that designed the CPU for the Super Famicom. The original monitor as a Multisync VGA monitor, which accepted 15 kHz video from the Mega Drive portion and the 31 kHz signal from the PC portion. The Mega PC can also play any Japanese and/or US-localized game as well as unlicensed games.ДЄlthrough the video always originates from the 15-pin VGA connector, the video timings differ between Mega Drive mode and PC mode.
