Weehooo!! Lots of action around here!
Ok,
@ sredmyer - yes, mc/GUI056x attempts to support C200 / R200. Seems to work better on XP Professional / MCE. Not so well on Vista, so far. Keep iun mind that the firewire / SCSI boards in the Powerfiles are not as robust as the Sony. They get confused easily. Forget about seamless hot-plug and power on/off cycles. Nothing but a power off/shutdown/power on/reboot will get you back. Well not entirely true - sometimes you can uninstall the sick device and scan for hardware changes. Right now, I have one Sony, one C200 and one R200 hooked up to SEPARATE firewire ports on a laptop running XP Pro, and I can control all drives and changers - sort of. Still a few bugs in mc/GUI.
@kejava - sounds like a fun project, but I think the transport logic and timing would be difficult. I would not want to spend my time on that. We had Powerfile, Microsoft and Sony all collaborating to make those beasts function at least at the level that we have them now. I think I would prefer to try and adapt to what is there. I mean at some point, I actullay want to get around to using the darn things - not just writing code!!!

Now that my C200 is kind of usable, I can return my loaner R200 and then use the C200 as a test rig to explore Blu-Ray. I have two ideas at this point: (1) Use a MAC-style slot loading drive attached in front of the eject slot. The C200 pushes the disc way out there - I think far enough for a slot-loading drive to grab it, The rest is all a matter of code and synchronization. The eject solenoid presents lots of mechanical or electrical options for devising a sensor to prevent collisions. (2) remove one or both of the C200 drive guts, leaving the disc insertion/retraction electronics and hardware in place. The slot-loding drive would have to be mounted (tight fit I think) directly in line with the insertion arm track. With this arrangement, I'll bet that you could plug them right into the IDE pins on the 1394 board and use the changer as normal. (If a SATA drive, there would have to be a SATA-IDE adapter - they are small and work well).
Now if that works, next game would be to fit a mini-PC contoller and A/V controller inside the cabinet. I estimate this to cost $1500 with one BD drive, or $2500 with two - at today's prices for slot-loading BD drive. Or, I will just wait until Sony lowers the price of the HES (now $3500).
re flash update: Yes there was an old firewire / firmware update on the SONY web site for the 1B1 for MCE 2005 (XP Pro base). Not sure if it is still there. That package included a firmware update for the changer along with DOS-based update utility. There are also firmware update fpr the MATSHITA drives.
re parts:
Power Supply: A-1158-461-A
1394 PCB: A-1158-460-A ($68)
Controller PCB: A-1158-459-A ($112)
Drive assembly: A-1158-462-A ($278)
Part numbers are from Sony Disassembly & Assembly Manual - found using Google - about $18
3.6v lithium battery needs replacing every 5 years or so. I found one for $6 at ElectronicsNMore.com. Brought my C200 back to life.
