  1. I will be done with reworking the quirks of the first revision. Once that's it done I'll create a second fork of the board with through hole sockets for the two large PLCC ICs. (68882 and GLUE) Sockets are going to be problematic, because most of the time the old parts you pull off a board will have corrosion and make very bad contact in a spring loaded socket. Having two board versions you can choose if you want it to be easier to solder (because through hole sockets) but with the tradeoff of possibly having to go through extensively reconditioning the ICs. Going for through ho
  2. No. You will always need a donor SE/30 board to pull off a few of the Apple custom ICs.
  3. Well done. The break around that via is very common. I already had a few boards with the exact same trace broken. If the pullup resistor is still connected the Mac will turn on but won’t turn off on its own from software. If it’s disconnected like in your case you’ll get just the behavior you observed.
  4. I suspect the Presto040 (or whatever it was called under the Donoho brand) is the successor to the Tokamac SX made for the IIci. Btw: I contacted the person with the IIfx card from the thread linked above asking if they would send me the GAL from their logicboard and the accelerator to recreate everything. Didn't hear back from them though. Won't blame them though, having one of the few working Tokamac IIfx setups.
  5. Mind sharing how you did that exactly? I have a set of Nubus TDM hardware as well that I have yet to get to do anything useful without a TDM mix activation.
  6. Did run them without noticing any further issues, so I guess it's fine to have them here... Remember, those aren't dumps of the actual chips but code I rewrote to match the behavior of the originals, so use at your own risk. If something goes horribly wrong harm to the analog board is possible. Jedec files are for standard 16V8 devices - either real GAL16V8, PALCE16V8 or ATF16V8. I used ATF16V8B-15 for the 5 DIP chips and an ATF16V8C-7 for the single PLCC chip. Be aware that ATF16V8C behave differently because they don't have internal pullups. I ha
  7. I'd love to take one I think I even have enough spare parts here to populate one.
  8. My BluePills all had the Blink firmware on it as well from the factory.
  9. On my spinoff of the board there‘s separate jumpers to select power sources for the BluePill and for termination. If you‘d implement the same on your board that would solve the problem of having to run an extra jumper on the Plus. It would boil down to moving a single jumper if you want to power everything externally (USB or another 5V source) On another sidenote: just confirmed the passive termination does even play well with the IIfx, which is otherwise very picky with termination.
  10. The Sonnet adapter is easily doable without desoldering anything (except the PAL to dump/reverse engineer it) I am pretty sure though that it needs a specific Sonnet accelerator to go with it. You won't be able to use two normal LC PDS cards with it.
  11. It is on for me as well, but the actual voltage that's getting to the BluePill is rather low on some of the machines I tried (mainly a lot of different SE/30 logicboards, IIcx, IIci, 475, LC) The SCSI2SD must somehow be more tolerant to lower voltages. This is how I connected the SD card: On the original ArdSCSino github repo there's schematics as well: https://github.com/ztto/ArdSCSino-stm32
  12. The 630 DOS board is actually a LC580, that’s why it had two RAM sockets.
  13. ExFat did not work for me, neither did the factory FAT32 formatting the SD card I used came with. After reformating the card everything was fine. I do need external power though on nearly all machines I tried so far - which is not a big deal as I made a few boards with a Molex connector, so things will plug right in. The SCSI2SD will work just fine when powered from the term power supply on all those machines, so there definitely are a few differences in power requirements here. What I noticed is that despite the Quantum drive identification thingy it won’t show up in App
  14. Just count the pins VRAM -> 68 ROM -> 64 RAM -> 72
