What TechTool version to upgrade to(or buy new) for OS 9 (under OSX platform)

Hi, I have used Techtool 3.06 to boot from for several years when doing optimization/defrag/diagnostics.  

I now have a couple new CPUs, a G4 dual, and an Ibook,... both are OSX, but I startup and operate in 9.22.
by default and do nothing in OS X.

I found that my Techtool disc is not bootable off the CD on either of these machines.  

For cost-efficiency..(and probably an urgent need to defrag my drives) - just wondering what version of Techtool would be the right upgrade from 3.06, that will enable me to boot from the CD...to run optimization of  either of these machines' os 9 systems"?  

As mentioned i work entirely  in 9.22 and it is my default startup disk/system for everything i do.
OSX is entirely ignored on both machines.....i just know that Techtool 3.06 no longer boots up and i need to update tho the Micromat site didn't clarify the answer for
me.... BTW I also have a copy of Norton Systemworks which basically has the same issue going on. (bootable
on my Beige G3 with OS 8.6 or 9 but not beyond that).  

Your help much appreciated. Here's to a defragmented world.

Thanks

Mike

Just grab the latest techtool. It may boot you into OS X when you boot from the CD but that's irrelevant.

You can upgrade your v3 Tech Tool (or cross grade your Norton for that matter) to TT v4.0.3 at:

since you've still got Classic machine(s) on hand you can also update 3.0.6 to 3.0.9 while your at it (free download)
