I decided phpwiki was a clumsy pile of poo after it managed to thrash all my pages so I've switched to dokuwiki instead. Seems a lot better. ^^ So what do we have here then?.. Basically a collection of stuff that is of little or no interest to most people, I've put it here mainly for myself and people I collaborate with. Feel free to read anything, editing is locked out however. text/html 2010-07-23T19:57:11+00:00 Daniel Palmer http://wiki.cardboardbox.org.uk/doku.php?id=arcade:neogeopsu&rev=1279915031&do=diff Intro First Attempt - 7805/7812 Linear Regulators This was the first attempt. A very simple PSU based on 3A (I think?) capable 78xx chips. The only other components are a couple caps to smooth the supply in and out of the regulators. The 12v regulator is wired up to the 19v ac transformer and the 5v is wired up to the output of the 12v regulator. This works fine for small loads, but the neogeo was a bit heavy for it and the regulators heated the make-shift sink up pretty quick and then I thi… text/html 2010-07-23T19:54:29+00:00 Daniel Palmer http://wiki.cardboardbox.org.uk/doku.php?id=arcade:neogeostereo&rev=1279914869&do=diff MV1B Audio Schematic Main audio According to these Neo-Geo.com forum posts you have to remove some resistors to get a stereo line level feed out of the MV1B board. I don't think that's really necessary; If you take a look at the application manual (Japanese) for the YM2610 you can see it needs an external DAC to produce any analog signal (apart from the noise channel apparently). The DAC on the MV1B is a YM3016, which then goes to the C844G opamp to pre-amp (Hmmm.. Seems to be configure… text/html 2010-02-18T15:21:49+00:00 Daniel Palmer http://wiki.cardboardbox.org.uk/doku.php?id=coding:magukiddo&rev=1266506509&do=diff What it looks like A2030 text/html 2010-02-18T15:21:49+00:00 Daniel Palmer http://wiki.cardboardbox.org.uk/doku.php?id=coding:gbaromdumper&rev=1266506509&do=diff Introduction This is a small multiboot application that you can upload to your GBA using an xboo cable and xboo communicator and have the GamePak's ROM dumped to a file on a machine running xboo communicator. It works with both Linux and Windows, and should work with any platform that the xboo communicator software gets ported to. yay! text/html 2010-02-18T15:21:49+00:00 Daniel Palmer http://wiki.cardboardbox.org.uk/doku.php?id=coding:nexys2&rev=1266506509&do=diff Annoyances * You can't use Xilinx's Impact software to either send a bit file to the FPGA or program the onboard platform rom. * Can't use in-system debugging stuff like Chipscope. * There is an USB enabled 8051 clone on the board, Cyrus FX2 from memory, this has a connections to the FPGA which would make it fairly useful for projects, sending debug info over USB etc, Digilent don't seem to have any docs on how to use it..

After waiting a week or so for it to come from China I plugged it in and got loads of shit in minicom. I checked the simulation again, the waveform was perfect, timing was like .01% so perfectly within tolerances.

I didn't have my soldering iron, bits box, *anything* handy,.. So I trundled off to Hardoff and scrabbled around there for a while and found a half metre long DB9 <-> DB9 cable for 300yen...
