How the setting fuse bits should adjust when flashing the firmware for IP-BUS Emulator? I have built the board and trying to get it work. I made one to one copy of your internal comparator version but when I connect it to HU and try to change to CD/MD changer nothing happend.

I added some 100nF capasitors for powering lines and 10k pull-up resistor on reset line. Also using USB-port as power source. I'm using DEF-P5630MP as head unit which sould fit, right? Any idea what to do next?

Do I need Yammp or is it enought to have head unit to understand MD and PC with WinAmp?

I have PCB made for this but not yet haven't had time to test it. If ist functuonal I will sent prints here too.

Have anyone fixed T30 or any other Thinkpad similar a problem I have on mine?

My Thinkpad don't charge the battery and it does boot only with charger connected. Battery is fine it's tested on other TP. Also battery on Ultrabay functions similary.

I get the mother board out of covers and measured all the fuses which seams fine. Any ideas what look next? I don't feel like geting new mother board...

nice, is this tested and how well does it work?

*need to find some components now...*  

I'm also interested about winamp-plugin to get commands from Pioneer HU. With Nullsoft Winamp SDK, some low-level RS232 driver and Vitat's AVR code that should be relatively easy task to do someone who have skills to write PC low level software. Unfortenately I don't... =(

Anyway I'm studing this and if Vitat have ip-bus timing specification available I might try to do some code for this.

My idea is to do ip-bus driving on PC so no mcu is needed between PC (winamp) and HU. If thats not possible then some mcu (PIC or AVR) is needed to convert data so that PC have time to do also something else than watch the serial port waiting for a data...
