Perry's guide

That's not a solution though. Computers march forward and eventually flash wont be an option anymore. at all....

So unless you want to lug around another machine just for a specific purpose, it just isn't practical or realistic, or secure....

Eg: Can you run 16-bit apps anymore? No.... not without some sort of emulation or other insanity.

There are multiple other programs which are designed as a flash alternative. You can use these programs to open the repair guide (I use a FLASH alternative).

The repair guide is totally worth the 50 bucks and still it is.
 
Lightspark is a viable option for viewing stand alone .swf files. I think folks are hoping for in-browser viewing. Puffin desktop browser should tackle this but it requires a subscription. I think it's $2/mo. But it's a fantastic all around desktop browser so if you'd like to live your life with flash in general, it might be worth it.

Ruffle is also in development for rendering flash, but the latest nightly build doesn't work with the guide thus far.
 
For those having trouble with Flash in the tutorial, try this browser. It works on my computer but I'd like to have it checked on other computers (specifically with Win10).
Maxthon 6 cloud Browser

In the tutorial, check the page named:
repair_tutorial/switchingpowersupplydesign/switchingpowersupplytut01.htm

For those who simply want to check the ability to use Flash, the following page is absolutely the most monstrous page on my site. If it works on that page (without installing Ruffle), it passes the test.

If you comment, please comment on speed and completeness of loading (should be no large blank areas or areas that warn against Flash, other than right-click to enable).
