I just got a TurboExpress, TurboVision, and 5 games at a garage sale a few days ago for $2, but the II button on the TurboExpress doesn't work.
I opened it up to look at the controller board, and tried cleaning the contacts, but it didn't seem to help. I searched all over the net for information about the chip on the controller board, but couldn't find anything.  The part number is BU5782K. I found information on the TG-16 controller, but the TurboExpress seems to operate differently than a regular controller.  I wired up some LEDs and switches to the cable on the controller board and tried to figure out how it works, but I haven't been able to come up with much.  I thought I had it figured out, so I built a new controller board but it didn't work.  I could hear the game sounds, but the screen had no image on it (it was receiving power though).  I think that the controller board sends some sort of signal to the console to turn the screen on or something, because I powered it up with the console open, and with the original controller board connected, and when I disconnected the original controller board, the screen went blank.  Does anyone know what will work?

Thanks

Asking here is a good move, but I would also post a request for information here:

I'd just cut-n-paste your question.

The link is to the "Request Info" section... you might want to see if any of the other areas are more appropriate... but I think you'll be fine with the link I provided...

Great find, two bucks for just the 5 games alone is a steal. Which games did you end up with?

What a minute, the total for all of that stuff (TE, TV, 5 games) was only $2???

The games are:

Cratermaze (loose)
Devil's Crush (loose)
Galaga '90 (w/jewel case and manual)
Turrican (w/jewel case and manual)
Alien Crush (w/jewel case and manual)

You lucky bastard! :)

That's sweet deal tsukasa. In reality, each of those game are worth between $4 - $15 easily.
