  1. I'd go for a disc or a 3-pack (depends how they are being packaged) if the price isn't stupid, just for the nostalgia!
  2. It's a bit up and down this morning (UK). Can't get on using phone again. Firefox on PC is working but it takes a long time to load the page. Oh how I wish for stability and a new shiny certificate!
  3. I’ve closed the SIF Chrome window and reopened and it seems to load again… no idea.
  4. So that "Walkman" above is not a cassette deck then? It's a solid-state MP3 player? The equivalent would make no sense at all for MD! To do anything new for MD they would have to resurrect their old chip designs and they will probably be on a technology node that has long since been decomissioned in the wafer fabs (for anything but military and space applications that tend to use older technology). They aren't going to spend the money it would take to port their designs to a more recent node, the costs are just too astronomical for the likely return. However I'm waiting to be proven wrong. Re TH: No it was just an off-the-cuff comment/hearsay/gossip. No reference given. ps - SIF has stopped loading on Chrome on my iPhone. Still OK here on Firefox on the Win10 PC...
  5. @BearBoy Those links are great, thanks! it appears Sony still has the MDW80T as current product then, that’s comforting… and that we shouldn’t be bullied by those eBayers charging silly prices for new discs (or even 2nd hand ones!). Someone on Taoeheads was suggesting recently Sony had stopped disc production. Their site would suggest not. (Possibly the thread that gave me the link for these disc purchases). I wonder how interested these big corporations are in anniversaries when they don’t really have an active product line to promote. Sony electronics is nothing it used to be so I wonder how interested they even are with exploiting it for a generic promotion of the Sony brand?
  6. @BearBoymy second batch are boxed like yours. So whilst these aren't decorative discs like we've seen from the past, these are a subtly different model, MDW80T, from the "Basic" range, MDW80BC, that we thought were the only discs still made and "bulk" packed in the boxes of 25. Maybe they are the same inside (as in disc caddy and slip case). I don't have any of the "Basic" range to compare. I can't find a manufacture date code on the box, but I presume these are all new-new. The box packaging doesn't look aged in any way, it's still crisp in colour and form. My previous batch of 10 (from the same seller, although his "last 10") were lose packed in a plastic bag, not in boxes. But they were MDW80T too and the wrappers are also crisp and seem new-new.
  7. @BearBoy are your discs boxed? What specific model are they? They look different to my original batch at least in the packaging. Will open my new ones shortly…
  8. He’s hiding 60 discs in there not the 20 he said he’d bought 😆
  9. Snap! Mine came today too 😀
  10. Wednesday for me. But if the last order is anything to go by it might be sooner. Initially on this first JPN purchase the bank blocked my credit card, but once that was resolved it was shipped on 18/Jan and I received it on 20/Jan! I notice the price went up. Hopefully @BearBoy I didn’t cause too much inflation on your purchase! 🥸
  11. Chrome on my iPhone SE has worked for read most of the time the site has worked at all. Now it’s working ‘ok’. Chrome on PC doesn’t want to know, so I installed Firefox and that’s ok once the certificate expiry is bypassed. If only we could get the certificate updated I think we’d be properly back up and running…
  12. Group function is just firmware on the microcontroller. They use the track name to carry group information. I think if you put a disc with groups into a non-group machine and scroll the title you will find more text that relates to the grouping. i.e. it’s not related to the ATRAC chipset it just happens to be something Sony introduced late on and MDLP was well established by then.
  13. I think group came in on the x70 decks like my MDS-JE770. I think it’s the only thing that differentiates the x40 and x70 families! Type S didn’t come in until the x80 family.
  14. I’ve got nuthin’ on you @BearBoy. Just had a count: 86 x 74 mins and (72+40) x 80 mins.
  15. Sorry 🥸🤣 You’ve done pretty well over these years though, this is the first ‘success’ I’ve had! 😆
  16. What did you do…? 😁 20 discs I’m thinking 🤔
  17. I hope so, I just spent £92! 😆
  18. Yea just a vanilla Amazon order. No other charges - order said ‘taxes included’. The box doesn’t have a customs label so they must bulk ship the parcels by Amazon and UK customs must trust them! I just ordered one pack of 10 because I thought UK customs and ‘brokerage charges’ might get added but no. So I just ordered another 30 🤣 now I’m happy with the process. They’ll come out at £3 a piece. UK eBay for NOS is no cheaper at the moment. I’ve got a decent stock of discs although I’ve gone through quite a few recently copying CDs and recording radio programmes. 😊
  19. I thought I’d try an Amazon.co.jp purchase. Look, I know I’m way behind all you chaps… this is new territory for me! My first new-new minidiscs 😁 £3.70 ea delivered (which is a little over the £3 I try to pay for NOS) - and arrived in just a few days. Now I know this works and I don’t get scammed I might go again! 😎 Oooops…
  20. Belts are back in stock. They sell so quickly Charlie has another order in with the supplier!
  21. Quick note that Charlie is currently out of stock of this belt (15/Jan/22). I’ve dropped him a note to ask if he’s getting any more made (this was a special order belt for us folks per the thread above). Edit: Charlie got back to me within 5 minutes! 100 belts on the way to him as we speak!
  22. PCB v1 info for anyone who cares (schematic, pictures of PCB, Gerber files). ETA: C30, C33 should be 100nF (0.1uF) NOT 100pf as on the schematic/BOM. SPDIF Output.pdf PCB_PCB_SPDIF Output_Top.pdf PCB_PCB_SPDIF Output_Bottom.pdf PCB_PCB_SPDIF Output_Silk.pdf Gerber_PCB_SPDIF Output.zip
  23. Sorry I didn't realise the photos were so big - shrunk them now I've managed to get on the site via a PC and Firefox (rather than on a phone). Indeed Stephen, that was the first project that made me dig into the TOSLINK circuits. This new project was originally pretty much that splitter without the input receiver and wired into the machine, but then @BearBoy and myself started discussing a coax output, so I looked into that and added one. I'm not happy with the coax RCA socket on this v1 PCB since it doesn't have any mechanical support. The one Sony use has a screw that can be used to secure it to the case for mechanical support. The one I have used relies on the solder joints to the PCB (although I did pad out a large area of copper for mechanical support). Subsequent to sending off the PCB design for manufacture, I finally tracked down the part that Sony use (attached) and found someone on eBay selling some, albeit with the black insulator rather than the usual gold/orange for SPDIF. None of the mainstream suppliers here (RS, CPC, Farnell) stock this component. I think Mouser might list the range but I didn't want to buy a thousand or have one shipped from the US at great expense. Anyway I'm in the process of redesigning the PCB for that (larger) part, but I haven't fully tested this v1 design yet, so won't order a v2 design until that's complete. Regardless, this board could actually be used sub-equipped as a single or dual TOSLINK output, and as long as your machine has SPDIF internally (which it will if it uses the Sony CXD DSP chips) and 0V and +5V then it can be fitted. The electronics is easy, it's the taking apart and drilling the back panel which is the hardest part. I have some spare v1 bare PCBs if anyone wants one to play with. I'll let you know how I get on with the v2 and if anyone is interested, give me a shout. You lot might get a little prezzie anyway for your ongoing help and encouragement! I suppose what I should do is do an "all features" PCB that can be a splitter or fitted internally to a machine with whatever combination of TOSLINK/Coax outputs you want. I guess this could end up being a bit over-engineered because the splitter needs a power supply and an input circuit whereas the output board doesn't require either. However I guess the point is I know about all of the building blocks so if you fancy something, drops some ideas around. After all these little projects come about from suggestions/ideas/threads on here! 🙂 Boy, it's great to be back... pjras1x1s_x_series_cd.pdf
  24. It has to wire into a couple of points on the main PCB (or stuffed into the ribbon cable socket before @sfbp pulls me up on that one!). The machine doesn’t need to have any digital I/O on the back panel already. I’m only really familiar with the Sony machines and it should work with any as they use the SPDIF protocol natively internally. Otherwise this PCB has the interface drive circuits so doesn’t rely on the main board having any digital outputs already.
  25. Twin TOSLINK plus coax output board. Transformer isolated coax output based on Sony MDS-E10 ‘pro’ output stage. The pulse transformer is the most expensive part by far (about 4GBP) but the PCB is padded out for a couple of options to mitigate against availability issues. This project is partially @BearBoy’s fault 😆👍 I subsequently found the part Sony use for the Coax RCA connector so I will redesign the PCB. I also missed one capacitor in the coax circuit. No real consequence but I’m a stickler for detail… I originally designed this for my MXD-D4 to provide TOSLINK output from both the CD and MD sections. However with @BearBoy’s input I added the coax output and selection jumpers so it can be used with an MD-only machine and thus add twin TOSLINK and coax outputs. Just a DIP 74HCU04 IC goes in the socket.
