On web site you found the shematic, you can create the PCB.
I have started the design for testing:
From the original, i have removed the coldfire IC & connector.
I have added
1) USB connector for direct connect the PS2/USB.
2) Led for floppy
3) The LCD with backlight can be place on board or external.
4) I use RJ45 for connecting to Mega ST, STE and TT and i have create another small PCB for easy place in 1040, with reset & floppy signal.
5) Reset push button
6) I/O connector for place inside the 1040
is prototype, i waiting part before order the PCB.

ATTENTION: The schematic on the webside is wrong!!! The pin assignments of the mini-DIN connectors for keyboard and mouse
are "mirrored", means supply voltage Vcc is connected to pin 4 and ground is connected to pin 3. But this is wrong, pin 4 has to be ground
and pin 3 has to be Vcc. DATA and CLK are also wrong.
Please look at the correct schematic in eiffel.lzh archive/eiffel.hyp helptext.

PIN 1 --> DATA
PIN 3 --> GND

PIN 5 --> CLK
In eiffel.hyp (correct):
PIN 2 --> DATA
PIN 3 --> Vcc
PIN 4 --> GND
PIN 6 --> CLK
