  1. Yeah, that would be great. It doesn't have to be under my name. I just want the community to have more accessible knowledge. If you could upload it I'd really appreciate it! 😁
  2. Hi everyone, While rummaging through the nooks and crannies of the web I stumbled upon a service manual for Sharp's MD-MT80 and MD-MT90 models with their variants. I realised that the pages in minidisc.(org) for these lack such a document so I thought I will post it to the forum. Also, the MD-MT88 looks virtually the same as the mentioned above so this might come in handy for some folks. Admins uploaded it to: Cheers!
  3. I'm wondering what is "old" is for you as I start to consider myself as such 🤣 Homebrew is basically any software not licenced by the original manufacturer. For example putting NES emulators on a PS2 using FreeMCBoot or other means. Any custom firmware replacing or running alongside the original as well.

  5. This week I'm on holiday leave and I have been mostly listening to the one single MD I bought and which I have recorded with a Crystal Castles album. More discs are waiting for tomorrow's pick up from the post office. My excitement level is through the roof! Also I am about to put homebrew on my PS3 super slim so that's that 😊
  6. Yeah, Sega Game Gear for example has a slightly soft lens that's on the rubbery side so it was hard to get a good shine. My Sharp MD-SR70 on the other hand has a hard type of plastic used but it's also flexible so I'm kind of afraid of cracking if I use too much pressure. It only has a few tiny scratches so it might be easy to buff out, though.
  7. I know I'm reviving this but it's a sticky thread so I guess it's fine. I can recommend using a car headlight polish/scratch removing paste. It's dirt cheap and I've been successfully in using it to buff out some pretty aggressive scratches on PS1 games as well as a Sega Game Gear plastic screen lens to a point where some games got revived and the lens was shiny instead of matted with scratches. For the lens I used small car buffing pads with different hardness and for the cds just paper towels. And as in the original post, circular motion is key. The particular brand of polish I used was K2 headlight buffing paste (a white one) which is available in Poland and probably in most European countries. I assume any polishing pastę that can be applied by hand will work. Cheers!
  8. So probably no one follows this much but I for one have been able to fix my Sharp by using a hot air gun and an xacto knife. Two of the teeth were bent wider apart making the gap bigger and two neighbouring gaps smaller. Using the hot air gun I adjusted the temperature to about 150*C (302*F) and medium fan power, slowly heated the gear still attached to the shaft held in a soldering third hand. I only heated the gear to a point where the plastic became softer but didn't change shape. I then inserted the knife into the smaller gaps and dried bending the teeth back into place. With the knife I also scraped any unwanted plastic that got mangled by the driving spiral gear to avoid it skipping on any debris in the gaps. Then after seeing it looking kinda good, I reattached the shaft and everything back into the laser assembly and checked clearance by slowly spinning the gear that drives the broken one effectively moving the laser slowly from one side to the other. If it skipped or was hard to spin at some point I disassembled it back and repeated the steps with heating and scraping unwanted plastic. After 2 or 3 times the gear spun freely and after reassembly no skipping noise came from inside and after reading the TOC the unit displayed Blank MD (correctly) and waited for commands. It now recorded 5 or so discs from start to finish and there's no problem with playback or recording. Not sure how long it will last and I'm still on the lookout for spare parts. Cheers!
  9. Hi, I know the thread is kinda old but it might help what I have on this subject. I asked a supplier in Europe and the part has been discontinued so this route is a dead end. I know these models use the same part as your MD-SR50 -MD-MT50, MD-SR60, MD-SR70, MD-SR75, MD-MS721H and MD-MS722H. I'm in a similar boat because my SR70 has the gear with bent teeth and I'm looking for a replacement. I hope that helps in any way. -KorgerXP
