PC-50x family
First-generation consoles using cartridge-based AY-3-8xxx chips.
The PC-50x family is a series of home video game consoles belonging to the first generation, prevalent in Europe between 1977 and the early 1980s. All consoles in the family were produced in Asia and lack a central processor; instead, each game is implemented via individual chips in the cartridges, all based on the AY-3-8xxx chip family from General Instrument.

Lore & Background
The PC-50x family, also known as the SD-050, SD-070, SD-090, and 9015 series, comprises a range of home video game consoles produced in Asia and prevalent in Europe from 1977 into the early 1980s. The name PC-50x derives from the serial numbers of the cartridges (PC-501, PC-502, and so on). These consoles do not contain a central processor; all game logic is implemented by individual chips inside the cartridges, all based on the AY-3-8xxx chip family from General Instrument. The family also includes the 9015 series, which changes the name (9015-A, 9015-B, etc.) and the shape of the cartridges but uses the same AY-3-8xxx chips.
Common features across all consoles in the family include ten keys for choosing the game, a start/reset button, four or five switches for game settings, and two joysticks each with one button. Some consoles produced colored screens while others were black and white; among the color consoles, some were marked with the initial letter S for SECAM, the French color-coding standard used in France, its colonies, and Russia. For many models, the name includes the letters SD, which stand for Soundic (Hong Kong), the actual manufacturer of the consoles. The consoles were produced in China, imported and rebranded by several companies, and sold under different names.
Reader's Guide
The PC-50x family represents a notable approach in first-generation console design by entirely omitting a central processor and relying on cartridge-based chips from General Instrument's AY-3-8xxx series. This architecture allowed each cartridge to contain its own game logic, making the console itself a simple interface for power, controls, and video output. The family's prevalence in Europe from 1977 into the early 1980s, alongside its production in Asia and rebranding by multiple companies, illustrates the early global distribution patterns of video game hardware. The inclusion of both color and black-and-white models, with some color units using the SECAM standard, reflects regional broadcast differences. The 9015 series variant, which changed cartridge shape but retained the same chip family, shows an attempt at product differentiation without altering core technology. The family's reliance on the AY-3-8xxx chips, which powered many first-generation games, ties it to a broader ecosystem of early electronic gaming. Its legacy lies in demonstrating a cartridge-based system that predates the microprocessor-driven consoles of later generations, and in being a product of Soundic, a Hong Kong manufacturer that supplied multiple markets under various brand names.
Did You Know?
- The PC-50x family lacks a central processor; all games run on chips inside the cartridges.
- The name PC-50x comes from the cartridge serial numbers PC-501, PC-502, etc.
- Some color consoles in the family were marked with an S for SECAM, the French color standard.
- The letters SD in many model names stand for Soundic (Hong Kong), the actual manufacturer.
Frequently Asked Questions
What is the PC-50x family of consoles?
The PC-50x family refers to a line of first-generation home video game consoles that were popular in European markets from roughly 1977 into the early 1980s. Each model in the series is identified by a cartridge designation such as PC-501 or PC-502, and the entire lineup was manufactured by Soundic in Hong Kong.
Why don't PC-50x consoles have a central processor?
Instead of relying on a single CPU to run all titles, every PC-50x cartridge contains its own dedicated logic circuitry that handles the game's behavior. This means the console itself is essentially just a display and input shell, with all gameplay logic living on the individual chips inside each cartridge.
What chip family do PC-50x cartridges use?
All the game cartridges in the PC-50x line are built around General Instrument's AY-3-8xxx series of integrated circuits. These fixed-function chips handle the specific game's logic, timing, and audio without any programmable processing.
Where and when were PC-50x consoles sold?
Although produced in Asia by Soundic (a Hong Kong-based company), the PC-50x family was primarily marketed and sold across Europe. Their commercial lifespan stretched from about 1977 through the early 1980s, placing them squarely in the first generation of home consoles.
How is the PC-50x family different from other first-generation consoles?
Most first-generation home consoles of that era still included a small central processor on the console's main board, whereas the PC-50x family outsourced all processing to the cartridge chips. This made each PC-50x title a self-contained hardware unit rather than software running on shared silicon.
