During the IDEfile development I did some speed tests with different hard drives: http://john.ccac.rwth-aachen.de:8000/patrick/idefile.htm#benchmarks.

Today most people use CF cards or Disk-on-modules which are considerably faster than hard drives. With these solid-state drives

I think that there wasn't any difference between a Lisa 2/10 and a Macintosh XL other than the name, so there was nothing to convert. Maybe MacWorks was bundled with the XL, but that's a separate box.

I was under the impression that those sold as a Macintosh XL also had the MacWorks ROM set and the square pixel transformer installed, not that you couldn't remove those and go back to Lisa ROMs. Sounds like I'm wrong!

One of these days I'm going to benchmark the IDEFile against the XProfile. The IDEFile seems faster   ???

Some time and effort was spent maximizing the performance of the X/ProFile, I don't think a ProFile emulator could be made much faster than it is. Note that the media used can have a major effect on the speed; there are lots of speed grades of flash cards, and a well worn CF card may write more slowly than it was when new.

A benchmark of all the hard drives would be interesting and perhaps useful. Establishing some kind of test that could be done by anyone would be helpful so rare devices could be included.

I don't have edit permissions to the spreadsheet, so here's a bottom plate I came across today on the FB group:

Serial: B08B831610036
Applenet: 00103784
MFG: 83161

Well, thanks to another forum member I was able to purchase an X/ProFile and add it to my Lisa 2/10. Short story: It's fantastic. While I would have liked to get the original Widget working properly, and tried to for weeks, that is unfortunately beyond my hardware (oscilloscope) and skillset at this time. It's something I do plan to continue as a long-term effort, however. I think dialing in the pots to their correct values may still yield a working drive.

But the X/ProFile is also silent and, after listening to the noisy Widget bearings for 80+ hours I was ready for something quieter (so was my wife). Simple to install and easy to swap out the compact flash cards to try different operating systems (Lisa Office System, MacWorks, Xenix, etc.). The activity LED even lines up with the Lisa's front cover perfectly to reflect disk access. Happy that these are available for these wonderful old machines.

I haven't seen any evidence that Mac XLs had the serial/Applenet sticker from the factory. I'm sure there's a good number of Lisas that got converted to Mac XLs later down the line by dealers.

I ordered a Lisa 2/10 / XL in Canada just as they were all being collected and returned to USA. When it arrived I was told that it was one of the last leaving and was lucky they could intercept it.

IIRC, it has an AppleNet sticker, but it isn't easily accessible to confirm that.

What's the source of this number, 2700? Has it been verified?
I haven't found an AAPL annual report for 1989 that might have an official number.

But as far as contemporary sources go, the Herald Journal apparently published an article in 1989, referred to here:
https://www.hjnews.com/opinion/editors-corner-logan-has-interesting-link-to-apple-computer-history/article_b71cddba-f7a0-11e0-8054-001cc4c002e0.html

800 cubic yards / 2700 Lisas is 8 cubic feet (about 0.23 cubic metres) per Lisa, which seems reasonable.

IIRC, in 1989/1990, the actual number disposed of was ambiguous/mysterious/secret.

Those 2700 in the Utah landfill are almost certainly throwing us off,

I think my 2/10 was sold as an XL - not 100% sure though.

Might be nice to get first hand info on this... We could ping the owner of Sun.
