[NTLK] How thick is the ROM board?

[DXH]

The PCB thickness is determined by a number of parameters such as #layers, Cu thickness etc.
There are a range of thicknesses that can be fabricated, but, for practical and historical reasons, fab houses use a standardized set of sizes. These are usually 0.8, 1.0, 1.2 & 1.6mm for a four layer board.

The ROM board is 1.0mm.

The SIMM socket will actually support up to 1.27mm. The cam-in action will take up a small range of thicknesses.
