Very handy, and so small, dint make it, but still.

int i;for(i=7;i>=0;i--)putchar('0'+((v>>i)&1));

int v is input, it prints the binairy version of it.
I just used it at skool for C lessons, and its handy. Also I am going to start doing some psx and xbox programming, maybe ill post some demo's (with hopefully also work in Cxbx.) Actualy, the image and this last thing isnt realy related to my post, but maybe You dint knew about the resent Cxbx development.

Cxbx is awesome btw, so check Shoguns newest version, it runs the dashboard now.

Z80 projects

Its was 1986 when my Dad bought his first Computer, the Z80 based MSX the Goldstar FC-200.
Ram 64KB Vram 16KB and a Yahama video chip. He kept it as original as possible. And I enjoyed playing games and programming in basic allot.
Now back in 2009 I decided to build a n8vem and this is also a z80 based computer. both reside on a single pcb and working nice and more.

Today I decided to show you what more I did and what I want to do,
I have tried building an Z80 emulator using some sources I found and making it to a n8vem emulator someday (Yeah, not an msx, running cp/m only)

Going to make a z80 tester based on this: http://www.z80.info/z80test0.htm because I found some cpu's lying around unknown if they work.

Anyway, here is a picture and sources are gonna be released soon to (Horrible code from me)

based on a z80 cpu, this is my first emulator and it works :P

Ive rewrite some debug output, so that will be included to the sources.
I really need to add some commenting system here.

Next image is from a Arcade game im writing a "driver" for. MAME.
Its slowing me down a bit because I cannot find lott of time to debug my pointers and new memory locations.

It seem this version is slighty different than the USA and normal EU version (its a IT version I think.) more on this soon when I get more time for Mame and much.

Its been a while and lot have happened. See pictures for some things I did. I met new people and learned some basic Chinese, a long road ahead but we are getting there..

Actually the images are a bit bigger, please use right click and view image for full resolution (they are a bit scaled down but still large enough for some details)

This is the west gate of the Xiamen University, here are also a bookstore, Turkish restaurant and some nice shops where Ive been. actually I go here once a week at least.

openWRT on the Sitecom WL-559 / WL-173 54g Turbo ?

Doing some reseach on getting openWRT working on the Sitecome WL-559 from Ziggo (I found mine while dumster diving ;) ) and doing so i can confirm, the WL-559 is just a relabeled WL-173 Sitecom just for Ziggo (NL (BE? FR?))

This is based and hopefully helps the openWRT pages : http://wiki.openwrt.org/oldwiki/openwrtdocs/hardware/sitecom/wl_173?s[]=wl&s[]=173

This router runs on the Realtek RTL8650/RTL8651(B): http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PFid=11&Level=4&Conn=3&ProdID=70

Router

I found so far:

Serial com (TTL Rx Tx)
Posible JTAG (some people already found out, and got memory access)
USB 1.0 !! its not populated but datasheets and other family members of the RTL8650B has USB !
Sources availeble
Telnet ?

And some guy who build some of them? https://web.archive.org/web/20130606111447/http://www.csie.nctu.edu.tw/~cfliu/work/8650.htm

Please click readmore for all the research ive done sofar and ill update this article when im finding more.
