So the obey chip version 2 is just about out.  Fear not, we are working on a newer smaller form factor version that will cut down on installation time.  The new obey chip will install and solder on the hucard slot 9 pins.  Best of all, it will work on all turbografx and pce systems including the turbo express and pce gt.  Unlike previous versions of the obey chip, the main and switchless chip will be on one board.

Most excellent!

The new region boards are on its way.  It should arrive this Thursday.

The new region boards are on a flex board.  The way it works is that it folds 3 times like an "S".  The 9 hucard slot pins are severed leaving a 1/4 from the bottom and 1/4 from hucard slot.  There are soldering holes that lines up and place on the pins coming from the main pcb and soldering pads that lines up to the hucard slot pins.  There are 3 soldering holes for the wires for the switch.

Assembling these will be painful because of the small sizes of the passive components (sizes 0402) but I will know for sure when I get them.  Also the fab of the boards were more expensive then the last version so the new price will be $18 to $20 before shipping for the main board and still $6 additional for the switchless board option for the gt/te.

Hmmm, do I use the old obey chip or busy order a new one to save install time. Decisions...

[turbokon]

New obey region board vs old.  I will do a video of an install after our little vacation sometime next week.

So we ran into a few kinks.  Holes and pads doesn't quite line up.  We're making some changes to the design.

A little oops.  Aside that how does it work compared to the old mod? About the same?  I was just wonder if it'd perform better or not.

It should perform better especially with the everdrive since the data lines are a lot shorter without the use of wires.

We will get another batch run.  We are double checking everything again and will go with bigger footprints for the components.

It looks amazing, tubokon! Can't wait for the changes and the updated version of the board. You've now double-reverse engineered the problem and made it a clip-on design?  Dang.

Thanks, but I can't take full credit.  This is mainly thesteve idea and design.

im waiting on the mail here so i can finish testing the switchless circuit to see if it needs anything changed
switched mode was tested working by turbokon already

Just installed the oBey mod chip into the PC Engine Duo! Even though I've done a bit of repair work on and off, I never got around to doing a mod. This bothered me so I bought a few chips from Turbokon at MGC last year and this weekend a bit of magic happened.

I cut the pins, and installed the shrink-tubing and I was thinking to myself "what the f*ck, not only is there no turning back but this shit is pink and it looks ridiculous." On top of it my Hu-Card slot was flipping me the bird.



After a snag or two I realized that there was a large blob of solder connecting pins 20 and 21, so I cleaned it up and bent the wires with a small needlenose pliers so that the chip would be level with the heatsynch. I then encased the chip and all of the wires in a bit of bubble wrap (an idea that I got from doujindance, although I have no Idea why also he has like 3 f*cking RGB boards, an elephant and the encyclopedia britannica inside the systems he resells). I then bridged pins 29 and 30 on HU6280.

The chip went in, I mounted it on the RF shield above he Hu-Card slot, and cut a hole in the back of the case for a low-profile I/O switch. I filled in the edges with clear epoxy and double-checked the connections so that they could be quickly desoldered in the event of a repair.

but here is my working install as per BMW/Turbokon's guide and help in chat from chop5 and thesteve:



Love the design, guys and can't wait for the new board! I'll be picking a few more of these up in the next month.

Cheers! And thanks for all that you do!!

Thanks blueraven,  glad to see you finally installed the obey chip.

I have a TED v2.4. I have not tried nor do I have a previous version. But in all the systems I have installed the Obey V2 chip in all worked fine with the TED v2.4.

I've done more than these 3 but these are the best ones I have done with a clean look.



I am sure I can do better but as they say, practice makes perfect. These 3 systems are also using Turbokons RGB amps. The black PC Engine Duo I found using a connector to be extremely helpfull in case I needed to go back into the system I also use a thin velcro to mount the chip so I can move them or remove them a lot easier than using double sided tape.
