	This archive contains version 3.3 (aka -10) firmware for the 11403 O-scope. It is also said to work in the 11402 and 11403A mainframes, though I cannot say if there are any issues with doing this or not.

	In terms of chips, you will need eight 27C010 and four 27C512 EPROMs, all rated at 150nS or faster.

	Checksum-16 numbers and socket locations are as follows. All files are in Absolute Binary (Data I/O #16) format.

		160697710.bin	B270	U150

	As always, use these images at your own risk! If you are not confident with poking around in the innards of a complex device like a digitizing O-scope, or if you have not been taught the dangers of high voltage, I would recommend that you enlist the aid of a professional tech for assistance.

	Thanks are due to Hakan Hintze and Florian Diederichsen for providing the compressed archives. File-splitting from said archives, re-checksumming, and reorganization was performed by Yours Truly.
