  1. These displays talk displayport [Edit: eDP] on the ribbon connector, there are a number of projects out there for converting them to more accessible connectors. EmerytHacks: Connecting an iPad retina LCD to a PC An Open Source IPad Display Adapter | Hackaday [Edit] Also plenty of adapters available directly from ebay for both iPad 3/4 and iPad 1/2 the iPad 2 displays are probably cheaper and should scale 2x2 quite nicely.
  2. I found another related thing. Sorry if some of this duplicates earlier discoveries. The Apple Serial NB Card has a 10MHz 68000 to offload communications processing on Macintosh II's. This page suggests it also ran A/ROSE. But it supported MacAPPC which apparently was a networked program to program communication protocol from IBM. Perhaps this could be implemented on a raspberry pi or whatever and then leveraged from the mac side using the provided tools somehow? (Actually I think maybe the Ethernet and Token Ring cards supported this too). Network World F
  3. PLCC sockets seem to start at 20 pins, might be possible to trim one down to 18 with careful cutting and glueing.
  4. My Q605 has lost a similar volume of plastic, basically any time I touch anything the retaining clips just fall off. I held the board in with hot glue, but it's started moving again so I need to revisit that. Should probably 3D print something to glue into the case instead. Hope to pick up another case for it one day, it looks like it should fit any LC3 or newer LC2 cases, some of the LC2s appear to use the LC bottom case with the fan closer to the back panel.
  5. I didn't know this, will have to give it a try.
  6. Nice work, that came out great on the second attempt. At this point you should be able to hold it up to bright sunlight and see if there are any additional layers in there, but it looks like you've seen them all already. As you pointed out the other side is clearly visible in the areas where you're down to just one copper layer.
  7. So I'm the fool who ordered 2p1 version PCBs the day before @landoGriffin casually mentioned the connectors are flipped. Since then I've moved house and now JLCPCB wan't an extra $30US ($50 total!) to deliver to my "rural" address (3km from the edge of the city), even though it usually only incurs a $5 surcharge for local delivery. With that in mind, earlier this week I decided to populate the board anyway and see if I can get it to work. I figured I can just hang it out the other side of the raspberry pi instead of stacking it. I chose not to put the DB25 on there to s
  8. Oh yeah, that's a more thorough explanation. Shame that site doesn't start with a simpler example tho.
  9. Do you have ethernet on the SuperSE? Using Diskcopy to make images and copying them to my laptop with FTP works. But if your only option is to rip the image from your SD card, then the general gist of the situation goes something like this. If the backup files are just in a folder somewhere then it wouldn't be possible to just pull those files. But if they're in either a partition or separate virtual disk it's technically possible to figure out where the start of that would be. You'd need to look at your scsi2sd.config to see where your virtual drives start
  10. Some investigation into the Apple Pro Mouse reveals it has an HDNS-2000 which supports both quadrature and somewhat ironically PS/2 modes. The data sheet suggests it has an output high voltage of 2.1V, so this would probably need buffering. Unfortunately I think they're impossible to take apart without cutting plastic parts. http://www.chipmunk.nl/promouse/index.html https://kaibareis.de/kb.dreael.ch/temp/upload/Agilent HDNS-2000.pdf
  11. There are quite a few missing components, so you'd need at least a photo of a populated board to see what needs to be added, even then there would be a risk it may not work. The port above the coax looks like AUI, this suggests you can use a regular AUI RJ45 transceiver, there are plenty of those on ebay at pretty low cost. There are some links to sellers in this thread by mmu_man.
  12. You mean this pad/track/via combo (UI4p56 BBU)? According to the schematics (and my paint bucket agrees) the track that goes up from the BBU pad finds it's way to UE8p11 (SCSI/DACK) which looks correct. The via however appears to go nowhere. Maybe it's a relic of a revision when the track started going that way, but was later moved to exit the other end of the pad.
  13. What SD card adapter are you using? SD cards are supposed to run from 3.3V, so unless your adapter has an onboard regulator you may damage the card. If it does have a regulator then your 4.0-4.4V may be below the dropout voltage. Also it will have either voltage dividers or level shifters on the data pins, either way this would be messing with the levels between the uC and SD card. I recommend soldering pins to a spare MicroSD to SD adapter and using that directly on 3.3V from the BluePill. I'd also suggest powering the BluePill from USB and see if the
