RE: Good or Bad Vas5054A
Yes you can use odis-e 8.1.3 with this updated softing.
It is better to add the 2 missing capacitors. I believe they safeguard memory and it's data. Also 1 resistor 122 missing. Dont know which job they perform though I believe last one holds true in order to safeguard memory from corrupted data/voltage spikes/voltage lows. Capacitors are widely used in electronic circuits for blocking direct current while allowing alternating current to pass. In analog filter networks, they smooth the output of power supplies. In resonant circuits they tune radios to particular frequencies. In electric power transmission systems they stabilize voltage and power flow. I bought the following. 100nF 16V X5R -25'C to 85'C ±10% TDK NOTE rule: overrate working voltage by 2x. So for 5V modules capacitor choice is 10V. I only found 16V . |

As it is the later revisions of the original that why I have on board the later type Philips ISP1181ABS USB controller, when I see that and I see all the clones have that, I though it was a clone |

RE: Good or Bad Vas5054A
Looks almost ok, seems also amb is original, 5v memory but 55ns not 10, a few parts to change and will be as good as original.

RE: Good or Bad Vas5054A
Can anyone suggest any e-shop(international/europe) where is possible to order all or most of the parts for rework. Thanks!
