PAL16L8

364 bytes added, 27 September
Programmable Array Logic (PAL). Not to be confused with PAL, the colour encoding system for analog televisions.
The CPC6128 second page of 64KB RAM is controlled by a PAL 16L8 chip. It has the Amstrad part number 40031.
On the CPC 6128 schematic, it is top centre: [http://www.cpcwiki.eu/imgs/4/4a/CPC6128_Schematic.png CPC6128 Schematic] however the X inputs aren't distinguished.

* PAL16L8ACN [https://www.cpcwiki.eu/imgs/4/4e/CPC6128_PCB_Top_%28Z70290_MC0020G%29.jpg Source]
 
They both wear the same Amstrad part number 40031.
