=== Assembly advice ===
==== Order of assembly ====
The order of assembly of uIDE boards is as follows.
* Solder in the resistors, LEDs, 100nf capacitors (the tiny ones).
* Fit the pin headers (JP1, JP2, etc, making sure they are upright. I use an IDC plug for this and solder one pin, then adjust, then solder in all the other pins).
* Next fit the IC sockets, matching the orientation of the notch against the outline on the board.
* Fit the Z80 bus and IDE sockets (making sure they are square). Check the orientation of Pin 1 before soldering!
* The last thing to fit is the 47uF capacitor (C5), because it is the tallest component.
The adapter boards are not so critical. I usually fir the 50 way edge connector first, then clamp it in my bench vise to place the other components.
==== Diodes and electrolytic capacitor ====
Be sure that you put the LEDs and electrolytic capacitor in the right way round.
* With LEDs, the shorter leg is the negative end and it goes into the square pad (longer leg into the round pad).
* Electrolytic caps are the same, they have a long leg (positive) and a short leg (negative, often marked with a - sign or black bar on the side of the capacitor can). Match the positive leg with the pad that is marked with a + sign on the PCB.
==== Z80 Shims ====
When building a z80 shim, choose a set of header pins for the legs you are plugging into the Z80 socet on the computer's motherboard that are thin (do not use the the standard type) otherwise the Z80 socket will be damaged. Solder them in first, because the Z80 socket you solder to the shim probably won't let you get access to the pin header once fitted.
On the shim's bus connector footprint, pin 1 is labelled "A11" and is a square pad (all the others are round). Use an unboxed 40 way right angled pin header for this, as shown in the photos on this page, or you may find space is too tight inside the computer.
