The motherboard also had a spare ISA slot available for expansion, with a hole at the rear of the unit to accommodate this.

Its interface consisted of a start-up menu with several options, including a file manager, DOS, a clock and Mega Drive mode.

A monitor which was manufactured by a 3rd party company but with Sega branding, was available separately at a price of ¥79,800 (estimated US$600/GBP £300 at the time), which was capable of displaying 15 kHz RGB video signals from the Mega Drive hardware and a 31 kHz VGA output from the PC hardware, both from the VGA connector.

The system is moderately rare in Japan, although prices are rising rapidly due to collector demand.

A similar, but unrelated system was manufactured by Amstrad and sold under the name Mega PC in PAL areas such as Europe and Australia.
