Switching a memory stick...

[Slimby]

As we know, pin 9 of the MSPD is the VCC pin. I've wired up 2gb internally, pin for pin, with a 2 way switch on pin 9. Switching it one way connects internal to the power supply, switching it the other way switches the swappable memory. However, neither memory stick is recognised by the PSP. I'm certain I have a bad connection on pin 9, but do any of you gentlemen (or RA1N) think it might be something else?

i would agree maybe try a different switch

  good job of stealing the 100,00th post from Robin.

I might try soldering the two wires together, and seeing if that works. If so, I'll try another switch.

I just posted in another thread that you said this in, didn't see this one first.

If a switch on the power doesn't work, try putting a switch on the 2 grounds.  I asked about this on another forum, and thats what I was told should work.

yea thats a good way because switches like wifi and hold are negative and i'm sure slimby knows this already

However, from memory the data pin and the negative are connected. I actually think my wifi board is broken, because even when I have one memory stick connected up (minus the switch) it doesn't recognise the stick. I'll do a little more work on it, though.

Good luck man, with so many pins, it can be hard to  figure out.  I know Ive spent hours trying to figure out what I  up!

ya bro may the force be with you. that is going to tack some time. it would be great if it works.

i thought i read this some where recently now i know where.

Well, I managed to get the internal memory stick to read. I had a couple of loose connections. I think I'm going to take away all the wires in there now, and redo everything with the best joint I can possibly get. It's awfully crowded in there.
