I've read that the Duo 2300 mainboard supported all previous Duo LCD screens because it was also available as a (factory installed) upgrade. How did that work with the CPU heatsink "tab" on the frame being in different places on the 030 and 040 models? At least I think it's different. I'd have to dismantle my 280 again to check. The 230 is still apart and waiting for a "new" hard drive. I'm still trying to decide whether or not to keep the Duos or see if anyone will pay a premuim to own an Enineering Sample 230 and a Yeager Prototype 280. They're no Power Express (I sooo WANT one of those!) but for Duos the ones like these can't be too common, eh? ===== "When you are wrestling for possession of a sword, the man with the handle always wins."
