I've gotten my dad's //e and moved it into a MacEffects clear case. I also got from MacEffects the IIGS conversion kit so that I can put it in the old //e case. I have soldered in the power & keyboard sockets, but when I connect the //e keyboard, it fails to boot from the ReActiveMicro Drive/Turbo and instead says to check startup device. If I reset and go into the control panel menu, pressing the up arrow key causes it act as if it is always pressed. Pressing the down arrow key does nothing. Suspecting my soldering on the keyboard socket was a bit dodgy, I reflowed all of the pins and made sure there were no bridges; it made no difference. Has anyone else had this sort of problem?

Did the keyboard work correctly with the //e board? Maybe swap the board back into the old case and check it again?
I have the same symptoms with both the original //e keyboard and the MacEffects keyboard. I tested the MacEffects keyboard on the IIGS several months ago with exactly the results I described for the original //e keyboard. I hadn't even test the original keyboard on the //e. I just connected it to the //e and found a few of the keys are a little twitchy when pressed (sometimes it registers multiple presses, sometimes nothing at all), but I don't see how that could prevent my booting from the compact flash in slot 7. If either //e keyboard is connected, it won't boot; once it's disconnected, it boots right away.
Well, I finally broke out the multimeter to check the keyboard connector I soldered onto the IIGS board. Somehow, pins 13 & 14 are tied together (bringing X0 to ground). There is no obvious bridge, so I fear there is some sort of bridge under the connector, meaning I'll have to remove the connector to check. At least I've got spares.
Alright, it's all better now. I found some exposed traces between the pins of the keyboard connector, so I soldered in a new connector with as little solder as I thought I could get away with while using the multimeter to check each pair of pins for bridges and to the vias to check for continuity. I was able to boot into GS/OS and tested the keyboard in AppleWorks. All 26 letters work, though they are a bit twitchy because they need some cleaning. Now I just need to get a power supply that will reach either of the power connectors on the board while in the case.
