So I finally managed to get the logic analyzer on the 70011, and I was a little disappointed at the revelation that these mystery pins don't transmit data, so they look identical in the analyzer, 4 of them go high, 2 go low. I'm not giving up yet though, I just need to know from those in the...

You need to use a high speed cutting tool like a dremel, or a band saw in a pinch if its teeth are fine enough. Cutting pliers will run the risk of warping the board, and bending traces and planes into contacting each other. Sanding the edges is a way to prevent the latter

What kind of a budget do you have for soldering equipment? Because its a worth while investment to get a variable temperature soldering station, and if you really wanna splurge get one that has a built in hot air tool

Its fine as long as its not contacting P+, although you should try not to go nuts with solder, there is such thing as too much, although the exact amount is a matter for debate

Hit me up over PM if you have any questions, I'd be happy to help you get started

Yes you can absolutely make it portable. I was gonna use a 70011 before I switched back to the 79001. My plan for it was (and still is) to use an 8 inch 1024x768 screen and do it like an oversized PSP, but you could also go the other way, use a 5 inch screen and make it like an oversized...

No not really, the 70011 had test pads, but with the 79001 its really just a choice between vias or chip legs, and personally I'm doing vias

Yea it does require some quantum scale soldering skills lol, even just grabbing the chip legs on the stock encoder chip is pretty hard

Perhaps I'm missing something here, but what is the point of using a converter board when the ps2 outputs in VGA on it's own?

could you possibly see your way to allowing bb uploads in PMs?

I'm thinking so, maybe not much, since they probably didn't use much when the disc drive wasn't in use. Its hard to say without doing a baseline comparison of systems with and without those components

How are you doing sound? Have you made some sort of breakout board for the CS4335-KSZR?

You mean on the 79001 or just in general?

That board cant be trimmed to any significant degree The Dragon chip is on the far end of the board under the disc drive, and even if it wasn't, the DSP and BIOS are. This version was the last one before they realized how small they could make the motherboard, which gave rise to the 7900X...

I'm planing on getting a combo solder station soon, the precision hot air tool is a game changer

That's it lol, a craft knife!! and as an additional tip, you can make craft knife blades last longer if you own a whetstone

I was just preparing my board for trimming and I thought I'd post a little guide about removing ICs, provided you don't intend to keep them. Cut the chip legs with a razor blade on a stick (or whatever they're called) Pick up the main body Desolder and clean the pads PS: not sure why...

You are correct, the signal is only 15khz, but its still technically VGA

No, composite is not all you can use, the screen accepts RGB/VGA as well

I must say I'm always floored by the prevalence of english language skills in non english speaking countries, why does everyone know it?? Anyway I have an extra 79001 if you want it
