After testing this idea to make a ProgSkeet v1.2 actually WORK in the guise of a v1.1, it has been proven that the Phoenix PCB works I am glad to report.
1) Dumping and programming of on-board NAND - YES.
2) Dumping and programming of on-board NOR - YES*
3) Can the above be done using the supply provided only from USB - YES.
4) Does the 50way interface header work - YES.
5) Does it provide the same connection pads for on-PS3-board programming - YES.
6) IS IT A PROGSKEET v1.1 - YES
(*Note: will need to do a small mod to make this work).
For me it worked and hence I actually got my ProgSkeet v1.2 to do that which it was originally designed to do, so I am extremely pleased with how this project went and the result was being able to FINALLY downgrade my PS3!
Now I am not going to run away with this design and stick 2 fingers up at everyone... BUT I do have some concerns, mainly that it is by no means a simple task to actually solder all the necessary connections from the ProgSkeet v1.2 to the Phoenix PCB (even if I did change the design to make it QSB in style). One also has the added problem and that it is necessary to purchase extra components and solder them onto the PCB.
I have 3 Phoenix PCBs to hand and I am quite willing to sell them on if anyone is interested (and even populate them), BUT if you DO end up getting one of these PCBs this will NOT be a hand-holding exercise (technical questions aside). YOU WILL NEED UBER-SOLDERING SKILLS
and a good knowledge of schematics and not be a dumb-aZZ whining noobi. I hope you get the message!
So, it's FEEDBACK time. Is anyone still interested in this project?
My basic feelings are
1) It is NOT easy to solder on a ProgSkeet v1.2.
2) I am not willing to do this (if someone wanted to send me their 'Skeet) because:
a) it's a f-ing b-stard to do.
b) fragile and could not reasonably expect it to survive intact a trip in the post.
c) It takes me about 2 hours to do one and hence I'd charge about £100 to do this...
d) ... and see a) above, hopefully charging £100 will put people off asking me to do it!
Now, there is nothing at all to prevent people from taking the information in this thread and 'doing it themselves' and of course that would be cool as this is the original intent of this thread. In fact, if I get a good enough feedback response I will then post up 'orderable' Gerber files such that anyone can order in their own ProgSkeet PCBs and not have to get them from me.
Over to you.
