* If you are using a Z80 shim, take great care when removing the Z80 from its socket, and inserting it in the shim's socket. Attach the Z80 bus cable to the shim before attempting to plug it into the computer's Z80 socket, and again, take care when doing so. If your shim was assembled by me, the pins are gold plated and quite thin so as not to damage your computer's Z80 socket. They are easily broken, so be gentle.
* Pay attention to the orientation of expansion adapter cards on the back of the PCW. Fit them with the LED at the top (8256/8512). 6128 adapters have a more obvious orientation, again with the LED at the top.
