An odd request but im sure theres someone out there who can help. Im looking for some decent res scans or pics of the various GDROM controller pcb's used in different country Dreamcasts. Its not a particularly difficult process as all the screws are standard phillips heads, just some delicate finger work. I already have the common UK pcb which uses cusom Yamaha ASICs but am looking for the older ones that use either Tochiba IC's or even better the ones that used the OTI9220 OAK controller. Any help would be greatly appreciated. MrS
I will be opening my usa dreamcast this weekend to fix the controller ports I could take some nice digital pictures (4 mp). If thats ok all I will need to know is what chips you are looking to see?
The pcb im looking for scans of is attached to the bottom of the GDROM unit. The process would be to remove to case screws so that you can remove the lid. Then remove the 3 screws holding the GDROM down and gently wiggle it free from its connector. Flip the GDROM over and gently peel back the dust proofing felt cover to expose the 2 hidden screws .. then remove the 5 screws from the unit and the pcb should be removable with a bit of gentle shifting of the fish eye lens. Im not gonna lie and say my intention isn't to figure out the corresponding ATA pinout of the GDROM connector .. with any luck some scans will put me well on the way. MrS
Sorry was really busy this week and didnt get a chance to open up the old dc. I hope to get to it this week sometime.
