Hi Assemblers. I recently found a very cheap PS1 on the net and bought it as it was in pretty good condition and probably functional. It's a SCPH-9002 and indeed after I disassembled and cleaned it I put it to the test and it worked. Now I want to customize it a bit and since I'm not really happy with the original optical assembly (plastic parts and no metal rods etc... ) I want to change it with a better optical drive. To cut long story short, I just found a cheap slot-loading optical drive $3 from a car stereo and I want to "hack" it in place of the old drive. This is the part where I need some help. While waiting for the optical drive to arrive, I took a look at it's pictures and tried to gather some info about the drive and stuff... I'm not really familiar with optical drives, lasers and related stuff, but based on what I've found, the two optical systems seem pretty similar and might just be compatible enough to make the mod. Now my question is how should I approach this mod based on the hardware I have and the info that I've gathered ? Should I just use the mechanical part from the slot-loading mechanism, or use it as a whole with it's own RFamp/drivers or should I make a custom PCB with some kind of ribbons adapter and a PIC with a driver for the slot motor... etc ? Below are the data-sheets from my PS1, from the car stereo from which I think the mechanics came from and some pics. EDIT: Uff.... the attachments limits are quite spartan here... I can't attach the data-sheets...
Ah, something I was working on too. I have all the voltages and pinouts too. I did manage to get a SLD (slot loading drive) working by moving the motor but that was all... Did not get into it as my soldering iron fried the SLD so I packed it all up. The last thing I remember was that all the data was already encoded to how the PlayStation laser deck wanted it to be. This was because of the RF (Radio Frequency) Laser Drive Amp (Amplifier). You must by pass these I think... I didn't get to do more research because of the soldering iron incident http://forums.benheck.com/viewtopic.php?f=4&t=40590 Would be interested to see what you can do with it. Would also be willing to help you as much as I can!
