No, it's not that cool computer that Adam West had, that knew everything. Here is my "Battery Adapted TI" Computer: While I had the console open, I installed a USB keyboard adapter I bought from JediMatt. It works with every keyboard I have tried (3 Logitech radio keyboards). The keyboard shown with it is a Logitech K270. It also worked with a Logitech K750. Don't remember the third one's model number. The K270 is just a USB-radio keyboard. The others are Keyboard/Mouse combos, which I use in my other computers. Here's the interior: I used a little "tool box," that I had bought years ago, to hold two battery packs. One powers the CPU and NanoPEB, and the other powers an LCD monitor. Actually, this is the Mark 2 model, because the first incarnation had close to one volt, if I remember correctly, of noise on the power lines. My first clue was when the display made "funny" colors at the Ed/Assem screen. Here is a picture of the parts that went into the box: The CPU battery pack is 21V, 5AH feeding two DC-DC converters. One generates +/-5V, and the other generates +12V. The Display battery pack is 21V,3AH that goes directly to the display, which can handle 10-30VDC power. I'll put in a parts list so that anyone interested could build one. DISCLAIMER: I am (obviously) not responsible for damage to equipment that may result from building this project. Mine works, so far. The wiring kit for the batteries included a bunch of LEDs to monitor charge level, etc. They are REALLY bright! I'm thinking of splicing-in a resistor to dim them a bit. The black cable draped over top is the charging cable, from a 19V 5A power supply, in place of the "car adapter" shown in the "parts" picture. So far, so good. K-R.
