Hi xybots, what did solve the problem, i'am verry interested because i'am building the standalone as well. Still waiting for 3 more components

The forum looks almost dead here.

What power source did you use, voltage and amperes ?

Cheers,
Jasper

you can use a power supply between 7V and 12V. 9V is recommended.
500ma should be ok (this is depending on the lcd backlight consumption)

@Jeff

Will the internal Amiga floppy connector fit for voltage, the 12 volt wire ?
