http://www.reactivedata.com/3-SCSIBridgeEmulators/PDF/CF%20to%20SCSI%20June%2007.pdf That one is out of the question. I know because I contacted them back in April 2008. And I kept the email I received from them...Get ready for it:
Thanks for your email, the product is £750 each, ex VAT,lead time 2 - 3 days. They never did reply to my email where I said "Did you mean £75 or £7.50?" 😀

Does the Compact Flash trick work in all models?
If I went that route I would want to "retrofit" my LC, my SE, perhaps my IIci, and probably four Classics. Additionally, would I need any other adaptor to get it to work in a PC with an IDE drive?

Yup, there's a couple of threads on here detailing the experiences of others, but it seems like they work pretty well on desktop Macs. Personally, I've used CF cards w/ Acard adaptors (seen some on eBay in the ~$70 range) and cheapo IDE-CF adaptors in a few Quadras, a PCI Power Mac, a Color Classic, and a few IIcis that I gave away and have had no major compatibility issues. On 68k machines, stick with smaller cards to avoid glitches, and get a copy of FWB HDT or Silverlining to take care of drivers.
PowerBooks are another story. Some people have had their hands full trying to get a CF card to work on some machines. IIRC, people have had success with the 5300, and have struggled with the 5xx and the 150.
All you'd need for the PC (or any IDE Mac, for that matter) is one of the aforementioned IDE-CF adaptors. Which are dirt cheap. Buy a few different ones, because the build quality isn't always great. Anyone try a CF on a 630 or 580?

I assume you could get an IDE -> CF adaptor for your PC, or you could just buy a USB CF reader and access the CF card that way...cheaper and easier than using a SCSI CF reader, not to mention it allows you to keep the SCSI CF reader on the Mac. 😉

Can't say I read this whole thread, but I think old Quantum SCSIs were notorious for developing stiction. A gentle slap may free the heads from the platter in such a case, allowing the drive to continue working. I'm sure a search of Google Groups will turn plenty of stuff up if this is indeed an issue for these drive models.

Scott, to use that adapter, from what I know, you'll need a Mac that uses ultra-wide SCSI, and I'm pretty sure those compacts and pizza boxes don't. You'll have to check the Apple service manuals.

These things go for cheap on eBay all the time.

No Mac ever had built-in ultra-wide (68-pin). Wide SCSI wasn't even out till 1994. An ultra scsi (50-pin) adapter should work just fine though, the Mac will simply run it at the old SCSI-1/2 speeds instead of Ultra. Parallel SCSI protocols have always been nicely forward-backward compatible, you just have to adapt for the physical connectors.

As you can tell, I know little about SCSI on the Mac. *hides* 😛

Hello,
I have about 15 old Macs in my collection.
Classic I/II, LC I/II/III/475, Quadra 650/700, Mac II an so on...
But I am in trouble with my war treasure: Almost all hard disks are out of order.
They all have the same symptom: when I turn the computer on, they start spinning for a few seconds then stop. The screen shows a "?" (no system found) Mac.
Anyone has a solution to fix it ? I would guess that the hard drives you are trying to plug in are incompatible with the Mac.

The OS became corrupt. Re-install the MacOS
