This is the only place ever seen a good set of key pictures, so I tried my hand at measuring the bitting pattern. I don't feel confident in the details of my first pass so I won't post my bitting guesses for now to avoid misleading. But they're definitely 4 position, and somewhere between 4 and...

It almost certainly will work across OS. The caveats have generally been: sometimes a newer OS needs a newer driver, sometimes a newer device needs a newer driver, always be mindful of the 4.3 boundary. There's a doc out there somewhere with the recommended drivers for different machines, but...

Agreed with the above. The later revisions are noticeably shorter and work in more machines.

Per the serial in your other post: Approximate Build Date: 1983-11-20 - 1983-11-26 Build Sequence: 1165 No question that's one of the earliest :). Wonder what the other serials are!

Neat! A GUI for hfsutils is quite handy and HFVExplorer only works on Windows. Does this support both unpartitioned (emulator) and partitioned disks? Building in pdisk as well to allow for advanced partitioning would really be a killer app for a drag-and-drop tool for ease of use. It's great...

I'm finally getting back around to trying to see why my Turbo 040 is intermittent in my SE/30, and this thread nearly matches my experience. I've got pretty much the same setup. I'm running Bolle's Combo card with a firmware 4.11 Turbo 040 (ASIC version with onboard cache). I've returned...

Apparently I've left the lid off my Quadra for 3 months. Finally got around to installing it today and had...clearancing issues?? I haven't seen it noted anywhere else: with some 16-bit cables attached to the SE IV in a IIvi-style case, the metal box in the top of the case that serves as a card...

Are you sure it's not a SCSI2SD? Those only support raw card access, though you can split the card into multiple drives with the utility.

(How are you so fast?) Have you considered a passthrough PDS slot and a physical card ID selection? Stacking SE/30 cards is very handy and the more cards with passthrough, the easier it is to customize (of course, you can't really get past a few cards or power and signaling issues crop up)...

What's the difference in capabilities versus the normal Wide?

Feels like OpenFirmware for 68k :D. It'd be real funny if someone ported OpenFirmware to run as a bootloader. I don't know if it would be good funny or bad funny but it would be funny.

It has two modes (or in later models, only the latter mode): operate the system over nubus (with a stub running on the main CPU to route bus requests), and operate as a second computer on a daughter card which can load resources from the main system. While the former mode is interesting from...

I've been curious (but not seen benchmarks) about how much slower a fast 060 with no FPU is versus an 040 with FPU. It's gotta be "much slower" but how much, specifically? On the one hand I feel like I'd stick with an LC. On the other hand I've spent $$$ on a PowerPC card so clearly I'm not...

The screen seems surprisingly bright for the era. Camera lying, or is it really that readable?

I wrote up a little guide to identify fakes via chip markings. It'll never help you catch everything but it might be helpful when browsing online since I've seen a lot of the blatant errors listed here: https://eharmon.net/retro/macintosh/identify-fake-68k/ Let me know if you're willing to share...
