By choosing the PlayCity board, you have acquired a high-quality product which will set new standard features for
Amstrad and Schneider CPC 464/664/6128 range of computers.
Its most important features are:

* 4 counter/timer channels for programmable interrupt (including NMI).
* IM2 vectorized interrupt support.
* Raster lines interrupt support.
* CRTC hardware CURSOR interrupt support.
* The LIGHTPEN pin is rooted to a 4 pins LIGHT PEN/GUN connector for plugging compatible hardware through an adapter.
==Hardware Installation==
The PlayCity board use this feature to be sure that the CTC and YMZs circuits are properly reseted before using them.
== Light Pen/Gun connector ==
For making easier to adapt Light Pens/Guns from other systems or new ones, we added a 4 pins connector to the board. The connections are labeled in the board as VCC (+5V), TR (Trigger or D7), LS (Light Sensor) and GND.
Making the system compatible with [[Amstrad_Magnum_Phaser|Amstrad Magnum Pasher]] games, the most accuracy light gun system for CPC.
