A few golden rules for using to bear in mind when connecting the the uIDE cardsto a computer.
* '''Never''' attempt to connect or disconnect a uIDE card to a computer with the power on. Always switch the machine off first.
* If the uIDE device is external, protect it from stray metal objects on your desk. We don't want any short circuits, as these could damage your computer or cause it to crash.
* 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 and PCW 9512 adapters have a more obvious orientationare fitted on their side, again with the LED at right most as you face the toprear of the machine. Refer to the section on connecting for pictures.
