986-Studio have moved! (again)

Yeah finally I’ve finally moved and got all of my stuff back, I should be able shortly to resume working on 986-Studio’s project, including the Madeleine and all of my pending Oric projects!

Before:

986-Studio tidy

After:

986-Studio mess!
986-Studio mess!

Yes it’s a complete mess! It will take time to tidy all of that alone 😀

I will try to resume posting here on a more regular basis.

And many thanks for those who subscribed to my Patreon page! And it you are still not one of my patron, it’s never too late to become one!

Oric Cumulus Revision 2 & other projects

Hi everyone,

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.

Presentation of the Project Madeleine

Hi everyone,

I’ve promised that a long time ago now and completely forgot to add the presentation here.

So, during the RGC2015, I made a presentation of the Project Madeleine, my primary project for the WonderSwan, which include the flash cart I’m working on.

The PDF of the presentation can be found here: Projet Madeleine Presentation

OricMouse Project

Hi Everyone!

Here it’s time for a new project! (Why do I hear someone telling me that I already have too many project?)

So I’m prout to present you the OricMouse, a new opensource project for the Oric line of product that will add a Mouse input to the Oric!

The origin of this project come from Chema’s OASIS Project that you will find on the Defence-Force forum. OASIS is a game engine largely inspired by SCUMMVM and reading the topic I was thinking “this project need a mouse to be much more fun!

Apple IIgs composite output video mode

I am the proud owner of an Apple IIgs, that was gifted, for a few years now and played a lot with it. But as I don’t currently have a RGB monitor for it, I always used the composite output to get the video display, and I always complained about the fact that this fancy stuff only want to display in monochrome, or maybe in NTSC. I’ve searched for information about that for some times now and never found anything intereseting, and lots of people (including apple?) says that the composite output is monochrome, at least in PAL regions.

Oric Schematic Issue 7

Yes, nearly 1 year after the release of the Issue 6.1, I finally made the Issue 7 that would fix the VSYNC problem the previous release had!

What’s new in the Issue 7:

  • There is now a 2 pin header to plug a reset button
  • The hardware VSYNC should now work correctly
  • One of the two ROM socket has been removed to reduce the schematic complexity, but it is now possible to use the original ROM, or any EPROM without the need to change anything on the PCB, because the /ROMDIS signal has been changed!
  • Better, it is now possible, and easily to use a 32K EPROM with the addition of a switch (there are pin on the PCB for this) to select the memory bank.

Finally…

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.

Until today!
