The eBay haul so far this month...
The NEC TurboGrafx CD-ROM drive probably just needs a gear since the seller mentions that the laser doesn't home and is stuck in the outermost position. I already have several extra gears as well as a Turbo-CD dock to pair with this. It is strange that the seller was able to get a shot of the laser lighting up when that should not happen until after the homing limit switch trips. Still, I consider that a good sign. I also have junk Japanese CD-ROM² drives to get a replacement limit switch if I need to. Paid about $5 more than the last one I fixed.
A couple NES-101 "Top-loader" Nintendo Entertainment Systems for installing Hi-Def NES. I actually installed one into an NES-101 we picked up Sunday but the graphics are all corrupted. Checked every connection and still have no idea what is wrong. My brother confirmed it was something with the motherboard and not the mod kit by borrowing the Hi-Def NES + interposers, CPU, and PPU from a modded AV Famicom I also did. Installing these will help with troubleshooting that one.
A NEC PC Engine Duo for a friend who couldn't get the seller to ship to Canada. It works out since I've also got everything we need to make it whole:
3D printers to restore the missing door
Extra cap kit for TurboDuo/PCE Duo
Extra controllers I can fix up
Extra 6.3x3.0mm adapter tips that fit Duo for a custom PSU
Spare DIN connectors for a custom stereo AV cable OR mono AV cables that also work (have brand new extras for Genesis 1)
Of course after winning the cheapest PC Engine Duo on eBay, someone listed another one for a couple bucks cheaper, Buy It Now, WITH the door the next day after we won that auction listing. Oh well. That's just how it goes sometimes.
