Hi all, I have a pair of Sega's CD-ROM systems, a SEGA-CD (US) & a MEGA-CD (JP) Model 1's each. 
Problem with both is, can't read CD's, tray open/closes but do not read discs, they both turn on & display BIOS, they both have their territorial console piggybacked to them (Genesis for SEGA-CD, Mega Drive for MEGA-CD). 
If anyone is able to fix these please shoot me a post here, lemme know how much it would cost for service, would really like to get these bad boys up & running among my console collection. I'm in the NYC area if that helps to determine shipping. 
thanks, and I hope to hear from anyone soon..
Regards:
Nestor
