/* About the uIDE project */
Once the hardware is installed, drivers need to be written (see below).
'''uIDE-16''' can be configured for use on any Z-80 microcomputer such as the CPC range of computers. It is called "uIDE-16" because it decodes all 16 address bus lines to provide access to the IDE ATA registers as is required by the Amstrad CPC machines, yet it has an 8-bit addressing mode so that it can be used with other (more normal) Z-80 machines that only use the lower 8 bits of the address bus for I/O addressing. In this mode, some components (U1 and its socket and smoothing capacitor) may be left off the board.
'''uIDE-8''' is a similar design that just decodes the low 8 bits of the Z-80 adddress bus, and this can be used on the PCW and most other Z80 machines but not on the CPC machines. uIDE-16 has a user-configurable 8-bit mode that allows it to work with 8-bit addressed I/O as well. However, uIDE-8 is slightly smaller and cheaper than uIDE-16.
