For those who are interested in the replica 1, I am currently working on a improved revision. The changes are only those that users of the replica 1 suggested. ATX power connection instead of AT for more common power supply useage is one improvement as well as being able to use a wall brick power supply. The other change is the the serial port is changed to a USB port that creates a virtual comm port on your PC or Mac. This allows Mac users to enjoy the replica 1 as well.
The replica 1 SE is in prototype stage now and a prototype board will be arriving in about a week to test out. If things go well, the replica 1 SE will be available in about a month. I'll post updates as they become available.
