CF in Takky?

[MJ313]

Takky interests me... 3.3v regulator does not Some boards, like the 6500, apparently you can get away with not using a 3.3v regulator if you don't push the board too much and forego PCI. 6400 boards seem to require the regulator regardless and I *think* this is due to power draw?

I am wondering if using a CF to IDE adapter would reduce power draw enough to allow 6400 to work without a 3.3v regulator?

Also, in 2017, are there better (easier) options for use as a secondary power supply?

I don't have a takky and this is more just an entertaining notion at the moment.

you could always just solder the 3.3v regulator onto the board itself. This guy:

3 wires to solder.

That's incredibly helpful. Thanks much!

I ordered one of those up. Will probably go the johnklos route with this, attaching to the 6400 board. I think that's what you meant?

Works perfectly. Thanks man!

Works perfectly. Thanks man!

Would you be good enough to update the links to the pictures please?

Full circle as I find myself dealing with a 6500 in 6300 chassis issue!

2 things:

1. It's a shame the following link doesn't work anymore, as it had johnklos' original detailed information about modifying a 6400 board with a 3.3v regulator:

2. Photobucket was a nightmare... here's a pic of the original hack I did based off of the above thread.
