Sega-Naomi

:smt006 Hello everyone I looked through the tech forums for like an hr and was unable to find any info on this so here goes. I have a GD-ROM unit with a bad laser. I have read that it is possible to swap it out for a dreamcast laser. My question is does it have to be a specific laser for different revs of the GD-ROM unit. I have heard that some GD-ROMS have different controller boards that can only be paired with certain lasers. One last thing my GD-ROM unit has two numbers on it the first is 610-0617 right underneath it on a sperate sticker is 001109E0. Thanks in advance for to everyone who takes their time to post and help me out.

Don't have any info on taking the unit from a dreamcast, but spares are available:

In the Naomi GD drive, there are 2 different types of laser assemblies. You will need to keep this in mind when ordering a replacement. :smt018

I replaced one with a DC laser once...it worked fine, although I paid no attention to the laser model types at the time...guess I just got lucky hehe(or maybe it doesn't matter, I dunno honestly).

But the point is, yes, it did work. I replaced the whole assembly though not just the laser unit itselt fyi.

the older gdrom drives you can swap the whole assemble and pcb from a dc, the new gdrom drives you have to swap just the laser assembly, and use the new pcb.



i have repaired several gdrom units.



why sega never put a "Spindown" after title load is beyond me. (it doesn't ever read the disc after its loaded into dimm memory)

Actually, it does eventually spin down. It even makes the same sound as the Dreamcast when you open the lid.

Thanks a lot KI4SWY thats exactly what I wanted to know. Also thanks to every one else for taking the time to read and reply.
