CHAPTER 1 Hardware The RAM expansion slot is located on the RAM/ROM board, and supports up to 10 MB of PSRAM, for a total of 14 MB. See the “RAM Expansion Interface” section on page 10 for information about designing RAM expansion cards. RAM is always contiguous because only one size of RAM chip (4 Mbits) is used. As a result, software does not have to “stitch” memory. The RAM array is located in the system memory map between addresses $0000 0000 and $00DF FFFF, except following a

CHAPTER 1 Hardware the WD90C26 manages its frame buffer differently than QuickDraw expects, Pangola must perform byte packing and unpacking to support color modes other than 8-bit. For example, in 1-bit mode QuickDraw expects that each byte in the frame buffer represents eight pixels. For every byte QuickDraw writes to the frame buffer in 1-bit mode, Pangola unpacks the bits and sends 8 bytes to the WD90C26. Similarly, Pangola must pack 8 bytes into 1 byte each time QuickDraw re
