swiching off mod chip

[mgillespie]

I fitted my Magic 2 Modchip about a year ago. I want to go online, and need a method of disabling the chip.

Can I simply stick a switch on one of the supplies (or reset) to the board?

I don't want to try blind, as I know how picky the PS2 is about wire lengths etc..

What line should I stick the switch in? are they any recomended locations for the mini toggle switch I was gonna use...

Thanks.

i found this diagram and i am attemping it myself....
u just need a 3 prong toggle switch....

Hmm, tried to do this today, and the behaviour of the modchip has changed somewhat..

When the modchip is disabled, it does not work (duh), so it's working in this respect.

When the modchip is enabled, I cannot power the PS2 up from the Power/Reset button. I CAN however power the console up from the Eject switch, and the modchip DOES work...

The only functionality that seems to have gone amiss, is the powering up from the Power/Reset button.

I am pretty sure everything is wired correctly. Could this be a wire length issue?

Thanks

Hmm, even after shortening the wires as much as possible, it still does not work.

I have also noticed an other weird side affect.

When I switch the switch from DISABLED to ENABLED when the console is off, the console come on!!! I suspect this is part of the same problem....

Does this give anyone any hints as to the problem???

Cheers.

Well. OK I pulled the console apart, double, tripple checked the wiring, and ensured the track was cut.

It's still behaving the same way.

Has ANYONE managed to put a switch on a Magic 2 console? Did you use the wiring diagram earlier in this thread?

Looking at the diagram, when switched in the ENABLED position, the 3k resistor on the reset line no longer does anything. Is this intentional?

Should the track be cut the other side of the resistor, and the common wire attached there? Anyone know. I really need to put this console together tonight (it been apart all day now).

Help....

:-(

Well, The drawing must be wrong, as I have now got it working as expected. It must have been the lack of thr 3k resistor on the Reset line preventing the Power switch working. Everthing is now working as expected, so I can now go online... :-)

I would attach the ammended schematic, but I cannot see how to attach it (is it because I am a junior member??)

Here is the ammended Circuit Schematic.

I don't take any responsibility for deviating from the original circuit, all I know is that the original didn't work for me, and this did...

Here is where I located the switch on my V4 console. I choose this location, as there is a nice little cubby hole behind it for the switch wiring, and the modchip was quite close, so the wires can be nice and short...

ok cheers
is it all working correctly now??
