The Microvision (aka Milton Bradley Microvision or MB Microvision) is the first handheld game console that used interchangeable cartridges and in that sense is reprogrammable.
It was released by the Milton Bradley Company in November 1979 for a retail price of $49.99.
The Microvision was designed by Jay Smith, the engineer who would later design the Vectrex gaming console. The Microvision's combination of portability and a cartridge-based system led to moderate success, with Smith Engineering grossing $15 million in the first year of the system's release. However, very few cartridges, a small screen, and a lack of support from established home video game companies led to its demise in 1981. According to Satoru Okada, the former head of Nintendo's R&D1 Department, the Microvision gave birth to Game Boy, the follow up to Game & Watch, after Nintendo designed around Microvision's limitations.
The TurboGrafx-16, known as the PC Engine outside North America, is a home video game console designed by Hudson Soft and sold by NEC Home Electronics.
It was the first console marketed in the fourth generation, commonly known as the 16-bit era, though the console has an 8-bit central processing unit (CPU) coupled with a 16-bit graphics processor.
It was released in Japan in 1987 and in North America in 1989. In Europe, the console is known as the PC Engine, after the Japanese model was imported and distributed in the United Kingdomand France from 1988.
In Japan, the system was launched as a competitor to the Famicom, but the delayed United States release meant that it ended up competing with the Sega Genesis and later the Super NES.
A pre-production UMD of Grand Theft Auto: Liberty City Stories for the PSP, this UMD was found in a draw in the former R* Leeds office, the data matches final.
This disc suffers from bitrot, and only one layer of the game was able to be saved. The data thankfully was very close to retail and no major changes were spotted.
A prototype of Sonic Heroes for the Nintendo GameCube, this disc was damaged in 2016, due to old dumping means requiring a disc swap. Resurfacing the disc could render it fully damaged so we're hopeful a new recovery means is found in future.
