6 months later I own 9 of them, including 2 crystal ones.
I have TSOP-ed a few, found some weird chips in others, repaired a couple of Samsung DVD drives and fixed one of them retracing some lines.
Next step is to install an Aladdin XT+ chip to an v1.6 one after I rebuild the LPC port. Every day something new ( I have also set up a Raspberry Pi with PiPROM to extract the EEPROM of one of them, but I don't think I'll been going this )
Found a lot of information in here!
