: Documents the complex arbitration between the Z80 CPU and the ULA when they both attempt to access memory. : In-depth analysis of timing and conflicts between

The ULA’s most famous "flaw" is attribute clash – where changing the colour of one character cell changes the colour of the entire 8x8 block. The PDF will show why : The ULA has only one address bus for fetching screen data. It fetches pixels (bitmap) during one scanline and attributes during the next. By studying this limitation, you learn a vital lesson in memory bandwidth management for your own design. Back then, a single chip documented over 50
