The AMR, Audio/Modem Riser card WM9707
So I was doing some research into the Soundcard of the Xbox Alpha. Because I want to create a franken Alpha myself I need a soundcard. Well, it can work without one but thats kinda stupid and I want sound. According to some people on Assemblergames.com the Dash should work without one. Games will crash.
Me and a few other wanted to find or create such a sound card ourselves. But the resources to do so are very limited, in a way that you cant realy find documents or parts very easy. but it all changed yesterday, 14/10/2013. I contacted Intel, searched the archive and after a while Espes send me the Intel doc I was searching for http://www.ms-infobytes.info/pages/AudioModemRiser.pdf ,

and here we are :D I found first one for the WM9705, but this morning I used the Archive again:
On the whole wide web there is little to no information about the AMR slot used in many 2000 era computers, it was supposed to be kinda closed and such.
But here are the specs and some other intresting images :P original source also noted.
I hope this info and the files can help you If you stumbled on this, I try to make this sound card into something real in the next couple of month and maybe sell some boards if I have leftovers. Otherwise, make it yourself, order the main ic from somewhere like china and build it :D or source your own board. Original retail price, $99.
I spend $8 so far, and 6 hours searching.
I have made a backup of all the said files, so might one disappear, please contact me.

Summer projects and MSX
Recently I recieved a pakage from Japan containing the following ic:
This is ofcourse a Video chip belonging to the 80s MSX series. Awesome looking 64pin DIP.
I did another search on the internet and yes, I realy like to build a MSX from scratch or at least a MSX upgrade card to turn my MSX to a Msx2 or even a MSX2+.
A qoute from Wiki:
The Yamaha V9958 is a Video Display Processor (VDP) used in MSX 80s home computers. More specifically, the MSX 2+, MSX turbo R and the "TIM" upgrade to the TI-99/4A. The Yamaha V9958, also known as MSX-Video, is the successor of the Yamaha V9938. It was clearly conceived not to be a very major upgrade to its predecessor, which hampered its adoption. The main new features are three graphical YJK modes (with up to 19268 colors) and horizontal scrolling registers.
I now want to buy the following:
And of course make a PCB for this all.
I also know that I have difficulties keeping my projects simple, ill start writing a add-on Card for my existing MSX, try making some game.
And maybe start making an upgrade card in such a way that an home-brew MSX can also use it. Magic everywhere. Also I realy need to go understand Glue logic.
Hope I don't break stuff :D
and I rly have no idea, maybe I should do something with my N8vem aswell, to get "into" stuff.
Remember this? its my N8vem, it still running so now and then. I should make some more cards for it :P
Today (Or actually when I write this, yesterday),
Was a fun day, we learned a new Chinese song to sing "The Moon is my witness" (hope the lyrics are correct, we learned the Chinese ones)
Anyway, Sonia, a Chinese classmate showed me this picture at KTV the evening before. I like to share it with you. The Article around it was about Japanese Bento. And She had this awesome bag :D
After school... ehm, work.... doing not much today...
We went to SM City, which is a large shopping mall in Xiamen, China.
