Adrian's Digital Basement recently did a video on rejuvenating dim Macintosh CRT's. Might be worth holding onto the dim one and not tossing it.

Looks like a bed adhesion problem on that one side. I'm impressed, 0.2mm is teeny tiny!

That is just tragic. I am very sorry about your Performa 476. I do have an eBay success story to share. I bought a 12" RGB monitor, and since the seller had "Best Offer", I made him an offer very close to the asking price, but put a note asking them to carefully pack it since these are known to...

Thank you very much for creating this schematic. I will be using it extensively over the next few days to troubleshoot a sound issue on my SE/30! The Apple schematic was readable, but working through the blur of it added an extra layer to the cognitive challenge of buzzing traces.

Yes! I am doing a bit of final tweaking to the design but plan to release it soon. The STL will of course be free for anyone who has a printer, and if someone wants to buy a printed part from me, I'd be happy to run one off for them. Please keep reminding me to get everything posted. Thank you...

It was advertised in "as-is, not working" condition, with the symptom being "green LED, no picture". As I suspected, all it needed was to be plugged into a Mac!

I sliced it for a 0.25mm nozzle, just for fun. It would probably work, but I don't think you'd get quite as nice of a part as what you'd get from a resin printer or Shapeways. Plus I like the Stephen gets a bit from Shapeways, maybe enough for a coffee every now and then! :-)

Thank you very much for your generous contribution. If you don't have your own printer and need a mounting bracket for a SCSI2SD v5.1 or v6, please let me know and I'll gladly drop one in the mail for you, no charge.

Great news! As you can see, the kids have already commandeered the LCII to play SimCity 2000 on it. Which runs absolutely horrible, by the way... but they don't know that. As for the 12" RGB monitor, I found it on eBay. Condition was "as-is, not working". Green LED came on but no picture...

Most desktop printers are "FDM" (Fused Deposition Modeling) of "FFF" (Fused filament fabrication, same thing as FDM just no trademark). They print by extruding plastic through a nozzle, typically 0.4mm in diameter. While your stepper motors give you a ton of X/Y resolution, the nozzle size is an...

Sadly I did not. I ended up sending it back to my friend. I think I found a reference on the internet saying that there was a surface-mount component that is likely to fail, and I deemed it too high-risk. I wish I had come back and written down my findings here, but at the time it was...

More progress today! I modeled up a SCSI2SD bracket for it. I designed it to fit in SE's, Classics, and LC-series machines. On LC-series machines, it will mount to the chassis with the board facing up. In a Classic II, SE, or SE/30, it will mount with the SCSI logo facing up. I started...

@erichelgeson If you think you'll have spare parts that you won't be using, I have a short "shopping list": Forementioned floppy parts Hard drive bracket + two screws Short SCSI cable The three screws that hold the expansion bracket on The last three items were sadly missing from...

Thanks @erichelgeson! I'm happy to report that I've found some success, but not how I expected. The machine came with 4x256kb sticks in Bank A. I was under the impression that you must use larger sticks of memory in Bank A, and smaller sticks in Bank B. This source in particular notes that you...

I received 64 mb of RAM today from a seller on eBay. When putting it in Bank A with nothing in B, it did a horizontal zebra strip pattern and a never-ending loud chime thing. Horrible!  I tried doing 16mb x 4 in Bank A, and 256kb x 4 in Bank B. No fix. Then I tried 256kb x 4 in Bank A, and...

More news! I swapped my 4x16 mb sticks into Bank B, and I installed my 4x256 kb sticks into Bank A. Backwards, I know... but it boots again! I was able to boot into a System Tools disk, and it shows 2 mb of RAM. Is that an indicator that it's working, and I just need to install mode32? Also...

Okay, I have some good news, and some bad news. The good news is that the sound does seem to work! The bad news is that I installed my 4x16mb sticks of RAM in Bank A, and now when I power on the machine, it shows horizontal zebra stripes, and goes "CHIIIIIIIIIIIIIIIIIIIIIME" continuously, and...

Yeah, that's a good point. My issue right now is that I can't get 256 colors, because my monitor (and adapter) only support 640x480. So if I can get a 12" CRT, 512x384, and 256 colors, I'll be a totally happy camper.

Okay, I think I need a bit more help. @techknight, I'm looking to you a little bit! Still waiting on RAM so I haven't actually booted up an OS on this thing, but as noted early, there is no chime or bong. It's the same thing from both the speaker and the 3.5mm headphone jack. There are a couple...

Thanks @MrFahrenheit! It was a fun project. Thanks for checking it out! --- One thing I'd like to get for this is 512kb of VRAM. Anything that is meant for the LC-series seems to fetch about $40 on eBay. Are there any cheaper places I could look? Anything generic that would work?
