I tried putting my 2300 trackpad on my 280c and the 280c would not acknowledge the trackpad even with the control panel and extensions installed. Unless someone else can verify this works (and how), replacing your trackball with a trackpad on the 230 is not likely. And yes, you can just stick your 2300 board in your 230 and have it work. All of the connections are the same. There are no practical differences in the bottom of the case, however, there is a specialized heat sink you will need to install under the CPU stiffener or your CPU will melt. I believe Apple shipped the logic board upgrade in an assembled bottom case as a cost saving measure. It was cheaper to preassemble it in order to make the switch out quick & easy at your local dealer service shop. To have forced your tech to completely disassemble the Duo (which is what's required) to install the new logic board would have been even more cost prohibitive than the upgrade already was and allows more room for error. It also reduce the amount of packaging they would have had to ship it in as a logic board alone. This way, the factory in Ireland where the Duo was made, simply completed the production run of 2300s then continued making the bottom half of the product to fulfill the upgrades without changing any part of the manufacturing process. In essence, Apple shipped you the bottom of a 2300 without the trackball assemby, hard drive. memory and modem. There is no difference between them. The 2300 needed higher voltage to run properly which is why they gave you the new adapter. The old adapter works, but Apple does not support it. So, you would probably need to buy this as well. All Duo batteries will work with the 2300, but type I & II have very short battery life compared to the type III due to the 2300s increased power requirements. But, if you are going to do all of this, you will spend far more money trying to upgrade your 230 to a Power PC with a trackpad than simply buying a 2300 from eBay. Then if you don't like the trackpad, you can just swap tops with your 230. The only justification I can see for doing what you propose is if you absolutely need a grayscale screen for your work.
