The video out from the Lisa goes through a cabling adapter to the R G and B pins on a VGA plug.

Some more details here: https://twitter.com/compu_85/status/1441753541413150722

One change I made was to parallel another resistor on the output of the Lisa, so that it drives the signal a little harder: The 3 lines in the projector are each terminated, and having all 3 hooked up at once drags the signal down a bit making it dim.

The projector is an InFocus IN118HDa. This trick doesn't work on all projectors, but that older infocus supports EGA resolutions, which the Lisa signal is close to.

Great presentation!  I especially like that a Lisa was used not just for screen shots but as a presentation tool.  This is why Apple put the video out connector on the Lisa, to drive projectors or large displays for applications such as this. 

But the 800 pound elephant in the room is:  How did you get this working with a modern projector?  What projector did you use?  I am sure lots of folks here would like to know.

Again, Nice work!

@compu85's Jason Perkins presented Practical Apple Lisa at VCF East on Oct 8. The video of it is available at the following url as part of this video playlist:

Sound's a bit low, but great otherwise.

Just added classic Solaris packages as well as IPS ones to the bashbuild scripts, only took a single day of satisfying scripting on a Saturday

(or would that be better alliterated as csh'elling on a Caturday - but then again, it was bash after all?)  ;)

Just added package building functions in the bashbuild system for win10/NullSoft Installer System, Linux: deb/rpm/snapcraft, freebsd pkgng - these will be available the next time I push to unstable (probably in a week or so after more testing.) - these are only marginally tested, but they do produce installable packages.

I'll try to build a ports* for it in FreeBSD as well, and maybe an OpenIndiana/Solaris package, but these are far lower priority - if you care about these, please let me know, if not I might put these on the back burner and go back to UniPlus sunix v1.1 (fixing the profile code) and then back to TerminalWx instead which are next to do. These are the last barriers to the 1.2.7 release +/- a few other minor features.

I probably will skip NetBSD/OpenBSD/Dragonfly BSD packages for now.

I took a look at HelloSystem and I really like it and want to use it on some of my machines, so I'd support it with a package and it's own LisaEm.app bundle, but I couldn't get it to install on a virtualbox hard drive - only seems to work as a live image, so this will also be skipped for now until a more mature release comes along. (Tried 0.50 and 0.60.)
* Since FreeBSD doesn't install bash by default (and this is required by bashbuild), and I also prefer to use a custom, statically linked wxWidgets rather than the official one which is several versions older, I might just skip the ports dir for FreeBSD, will see how much of an uphill battle it is.There currently is a FreeBSD port for 1.2.6.2, however the maintainers switched it to regular borne shell, and rewrote-out the bash specific parts of the much older build script. That build script has evolved into its own package/library at https://github.com/rayarachelian/bashbuild )  Once all this package code is happy I'll update bashbuild with the new code as well.

I once had a one of the output gates stick on a SA400 floppy disk. The drive would kind of seek, but it sounded really off and didn't work properly. Eventually the gate in the driver chip stuck on completely and started burning the current limiting resistors!

As the drive steps you should see the outputs cycle in sequence. I'm not exactly sure how the circuit in the Profile works, but I can dig into one later tonight.

If you disconnect the stepper and power the spindle motor, does the stepper rotate freely? No grease divots?

Well I'll try it powered but disconnected, but when unpowered it moves freely and again, even doing its reseek to Track 0 the head moves as freely as it does my semi-working disk.

Whenever I try to LLF my ProFiles with BLU, I get similar failure messages a lot for no apparent reason, but USBWidEx and the ArduinoFile device that I'm currently designing can format the drives just fine. If you have a USBWidEx, maybe try formatting with it instead. Maybe this could be some sort of bug in BLU or something?
I don't think BLU is to blame here. Something's keeping the stepper energized at Track 0 whether the disk is connected to a Lisa (and I'd assume WidEx/ArduinoFile) or not. The fault seems to be entirely localized in the Profile itself.
