Yesterday, I finally got around to building a serial cable to connect my Amstrad E3 up to a PC serial port. Various people are working on trying to get all the the hardware supported by Linux for this device. http://www.earth.li/~noodles/hardware-e3.html has up-to-date information about the project. Due to my uselessness in interpreting serial cables it took me a while to get it working (due to transposing TX and RX). For reference - my cable (9-Pin D Female) has the following connections:

• Pin 2 - Tip
• Pin 3 - Ring
• Pin 5 - Sleeve
