Introduction

In this log, bugs and potential improvements for the Thunderbird system are described. Fortunately, only minor bugs have been found so far.

Bugs

• The CF/IDE busy indicator LED is operating in reverse. When a CF/IDE adapter is inserted, the LED lights up immediately, and when the device is busy, the LED turns off. 

Potential improvements

• The Thunderbird system, with the CF card running at full speed, draws almost 240mA. Therefore, it is advisable to use a larger polyfuse of 350mA or 500mA instead of the 250mA fuse.
• When reading a word from the IDE/CF card, the bytes must be swapped due to the little-endian/big-endian difference. This requires extra instructions, but a slight improvement can be achieved by handling it in hardware. Simply swap the low and high data lines at the CF/IDE interface.
