Do we have room for another N64P? (t64 WIP)

[snowpenguin]

If it was me doing this, I would leave out some components so that the board would be tiny, and then do another board to go under it with other stuff including screen, controller boards, fans, etc., then you would only need to plug in a few things for the back and that's it, still very thin, but extremely small the other way as well. Because right now, correct me if I'm wrong, this board is the same size or bigger as a chopped down n64 board, but it includes all this special stuff that could go on a daughter board.

Just me.

Keep it up, I want this done soon Kibble! WORK!

........
total cost: $300
n64 model used: kibble board (or kibble64)
time built 6 months on and off
... etc. etc.

LOL, kibble board. I like the sound of that!

If I can pull off making the full featured board, I'm planning on making a "lite" version that doesn't include anything that's not required, only the core system. By my guess, it would measure about 9x9 cm.

Just cause I haven't posted lately doesn't mean I haven't worked/haven't been working on it.

I don't have any updates really other than I would say I'm about 95% done with it. There's not too much more testing I can do on the electronics side as most of what I wanted to test is already confirmed working and added to the board design. I still need to add some of the smaller components here and there and I will post more updates when I have them but, for now, here's some of the latest pics. Notice the little PTH regulator on the bottom left.

Looks great!

Who wants to make the 200th post?

BTW, I was kidding when I said I needed more work

[nevermind1534]

Wow, that looks amazing. I'm definitely buying at least one board if you start selling them.

Looks like you're getting a lot of mileage out of the 2layer board! Nice job. Taking a page out of Nintendo's book when it comes to the SysAD bus

[dragonhead]

can you take a pic with the printout on top of or next to an originar n64 board, hard to judge how much smaller it is

I know. I just think it's funny that I was actually working on getting those two new pics up and when I got on to this thread, you guys had already posted before I had a chance to put them up.

The fact that they made everything practically pin-to-pin makes wiring stuff not so bad. I remember the first time I opened up my 64 several years back and thinking to myself: "That's it!?" Suddenly, its light weight was explained.

Here ya go!

So lovely <3, and its got all the power components to satisfy the N64's odd specs....freakin 3.3, 5 and 12 volts.....

Well, not quite. While it is possible to add a 12V step up, I didn't do it only because of lack of space. Besides, the only thing that needed 12V was the audio amp. I'll be replacing that with something else.

Seeing as you've thought about overclocking, have you also looked into undervolting? The 36mbit RDRAM datasheet quotes a minimum of 3.1V and some people have had success running the CPU/RSP at that voltage too. It could kill two birds with one stone: Lower power consumption and less heat output meaning the fan could be scrapped. Maybe I am too optimistic though.

Well, the voltage output is set with the resistor so it's just a matter of giving it a try with a different value. I did play with overclocking my test 64 while running Star Wars RS on it and I noticed that the cutscenes ran ahead of the audio. At one point, the game kept playing music and the game kept showing the same scene but it wouldn't advance to anything else. I'm sure not all games would have this problem but I have yet to try more games while overclocked.

Save that for later, it's not quite done yet.

Did you make a kind of plug for the cart slot?
I'm guessing its instead of relocation, the cart slot wires will already be like 3-4" long, right?

Hrm, I really would like to see how this comes out. =)
Wish i had expertise like this, oh my i would be tinkering to my whits end!

The cart slot will be relocated and will connect to that header on the middle of the top side of the board. The cart slot will have its own board that it will be soldered to. There will be a cable assembly to connect the two.

The n64 only needs 3.3 and 7.2+ volts. If you eliminated the 7805 you should be able to get away with a 5v battery, like an extension li-ion for a psp, good few thousand mAh.

[rikitheshadow]

5v is never an issue considering the availability of 7805 linear regulators.

It was the 3.3v that kinda gets on me nerves, tons of instructions on the forums for getting that, but its still extra work and another company you have to order from and from there you still have to mod it.
