  1. Hey, just tripped over this post. I'm wondering if you ever got your setup running. I've got one and it's pretty decent when it runs. I don't think it matters what SCSI ID the disk is, but you need to format it as a regular Mac drive, then it will show up on the desktop as well if you need to copy files on or off.
  2. Hotline is my recommendation for an original Mac file downloading experience! I actually just got my PowerMac 7100 on Hotline again last night, after having similar issues as you. There are a few Hotline servers still serving Mac files for download. Client here: https://macintoshgarden.org/apps/hotline Servers are registered to trackers, a list of which can be found here: https://hotline.fandom.com/wiki/Trackers
  3. All the same reasons you use an open source compiler to generate machine code for a proprietary CPU: Out of principle, because it's more future proof, and frequently also because they're just better software. I don't know about the Lattice tools, I've only used the open source ones, but the Xilinx tools are gigantic, slow, buggy, and the versions I used made you do a complete 7GB download for each tiny bug fix upgrade.
  4. Huh, interesting. So even a brand-new CF card is actually just a physical adapter away from the original PC AT bus from 1980-whatever? That's cool.
  5. Sidenote: PCMCIA is 16-bit, CardBus is a 32-bit slot, but unlike the older format it multiplexes address and data pins, so there's a little more to it than that. But I think CompactFlash is always 16 bit, it's just that CardBus slots are backwards compatible. I don't think CF cards are any faster in the newer slots, and I imagine you're right that the card slot will have a slower connection to the rest of the system than the IDE connector. BTW, Powerbooks support Cardbus from Wallstreet onwards according to EveryMac.
  6. I'm quite sure there was no discernible difference between ADB and PS/2 when I was testing my StarMax tower. I'd kind of assume that, for compatibility, whatever is handling PS/2 just turns it into the same kind of data that normally comes in over ADB, and that that's why there's no driver needed.
  7. Ah! The SCSI2SD v5.1 has an option to enable/disable termination. Unchecked it, and now it works. Wonder if that option basically means the SCSI2SD hogs the entire bus... Edit - now I see - it's because both the ACARD bridge and SCSI2SD have built-in terminators, and they were both enabled. Frailty, thy name is SCSI...
  8. I've tried both with and without termination. With an active terminator on the enclosure, I either get the blinking question mark or sad Mac and an error (which I don't remember). So the error in question is only with no termination. I tried a bunch of things earlier, as far as I remember the terminator didn't make a difference when it's only one device...
  9. Is replacing F245s with LS245s a good idea? I thought F parts were only used where the lower propagation delay was actually needed. I've also heard that sometimes mixing F and HC/LS.parts is done specifically to make one signal travel faster than another, say an enable signal that needs to be asserted before some data is set up, or similar.
  10. Right. I could find some references to it, but nothing that matched it specifically to SCSI issues. It's definitely flashing like it's being redrawn over and over. The drives are on separate SCSI IDs, but it just occurred to me that SCSI2SD can emulate multiple SCSI drives. I wonder if it's doing something funny or I set it up wrong somehow.
  11. Here is a weird one: I have a SCSI2SD 5.1 that I've been running my Quadra 700 off for a while. This works great. Before that, I had also run it from an ACARD IDE->SCSI bridge with CF adapter. It still works great. I've moved the ACARD into an external SCSI enclosure that used to have a very noisy drive. The enclosure also works great with noisy drives, or with either of my two solid state SCSI solutions. Except: I connect both at the same time (on different IDs) I get a flashing dialogue that says "Bluets & Granola bars". It shows up just before it w
  12. What do you mean more precisely? The schematic? I think an ADB mouse is a (relatively) smart device with a microcontroller og sorts inside.
  13. Eh, I can hardly open a cupboard here without a microcontroller board of some kind falling out, I'd love to see that code. Don't you need a transceiver to speak RS422 to the Mac, though? I was actually thinking about this today, since I have some high quality faders that I want to make a MIDI fader box. And of course, the sensible thing would be to just put MIDI sockets on it, but when it's for connecting to a NuBus ProTools rig, sensible isn't really a design requirement, more like the opposite...
  14. I just put a Noctua in my Quadra 700 power supply and it made a world of difference, noise-wise. The air that's coming out is quite cool, but I have noticed that the CPU heatsink feels, how to describe it, not uncomfortable hot, but fairly warm if I take the cover off right after shutting down. I've removed the floppy drive, not sure if that's messed up the air flow... But it's held up for a couple of long sessions with no weirdness so maybe it's fine? I might be picking up a 7100 soon, and I'd want to give it the same treatment. I'd like to get some sort of temperature probe to kn
