I didn’t updated here really often during the last month because I was quite busy and didn’t had a lot of time to works on my projects. I have more time now, and wow, I’ve made a lot of things recently!
As I previously posted, the Oric Mouse project is underway, I’ve discovered a few stupid mistakes and I was too confident when I made the PCB, I’ve overlooked something on the voltage that the 6502 and 6522 will accept as logic high, and of course both of them doesn’t like the 3.3V that I send them as a logic high… The result will be that I need to do some changes on the schematics for that project, but no worries, I will still be able to use the prototype I’ve made, but it’s just slowing down the project a bit, but it will be back on track quickly.

What’s that ? I #Wonder what it can be…? May be a #Swan? http://t.co/K1QNd88dBV
Ten years ago, two student from the Cornell University (North Australia) released the first public homebrew cart and software for the WonderSwan that does not use the WonderWitch. See here.
Their project was a major breakthrough as they where the first to document the WonderSwan hardware, and they are the original authors of the well known wstech document.
And after they made their release… nothing more. There were no concrete or public hardware development for the WonderSwan that went to a releasable product.

I’m sending right now the data to process the batch of PCB, due to some test (printer’n’paper test are the best thing to do!) I found that I stupidly use the width of the internal cartridge PCB instead of the cart itself, and found out that the PCB was going more than expected in the swan, so I do a small modification on the PCB to use a more accurate width, and add a T shape like on top to support more the cart connector, and adding a small surprise on this part.

As I am working on my big WonderSwan project, I will quite soon make a PCB run for making analysing stuff more easy and clean, that why I will introduce a new accessory: the WonderLyzer.
