A few pics of the controller to Dark Tower have been posted. You can find them at <http://www.mythtech.net/darktower>. (Pic #28 is missing, it is the same as 29, just out of focus). The board is about 7" x 3" (17.5cm x 7.5cm) There isn't a whole lot on it. 3 lights down the middle that are socketed, an LED digit display, a pair of LEDs (IR send and recieve, it is used with the picture disc to determine what pictures are facing out), there are a handful of resistors, a few Capacitors, 3 transitors (9112 D 07; 9113 D 05; NP2 3704) a choke coil, 2 diodes, and 3 ICs. The 3 ICs are all Texas Instuments, photos of them are on the web site (I made sure you could read the numbers, but they are upside down right now) The two connector looking things on the very end of the board opposite the LED digit display... are in fact connectors. The white one tied to the motor, speaker, and batteries, and the black one tied to the push button panel for user interaction (the push buttons are a flat 3 x 4 pressure panel connected to the board by a ribbon cable.) That is about it. I will try to draw up some basic schematics later (I'm a little busy at work right now, hopefully I will get to it later this week, or maybe next week). I don't know if I will be able to do any testing of my unit. When I opened it I found batteries had been left it in, and leaked. There is some pretty bad corrosion of the largest IC where the battery acid dripped on it. I am hoping it will still work when I clean it and put it all back together, but there is a chance it has been damaged. Also, the LED digits have suffered some damage (the laminate cover is peeling back I will post again when I have the schematics done. -chris <http://www.mythtech.net>
