help identifying mystery gate array

[Don Lancaster]

Got a bunch of these from an auction and they look valuable...

Shown is the bottom of the chip with the unprogrammed device number

The chip is presumed to be a popular mil-spec gate array in a gull wing
84 epoxy package.

The top of the chip is identified as

OTZy9-1420129
Revision-
Mfg Date- 9946
U7-1

Presumably these can be reprogrammed for a tiny fraction of original
cost new.

Believed to be full mil spec aerospace.

Need to know the original chip manufacturer and data sheet.
None of the obvious part number choices line up.

Hope they're not OTP (eg. antifuse) type, which are popular in such
applications for rad-hardness etc. Plastic PLCC-84 package, though.

Adobe Photoshop's "Perspective" crop function will allow you to get
rid of that irritating angular misalignment and distortion in a snap.

Drag the corner handles to line each of the four sides up with the
package edges, which defines the perspective correction, then pull the
center handles of each side out to define the area to be cropped.

And where do I get a free copy of Adobe Photoshop?

Sure does. Moreover, so does IrfanView with a much friendlier user
interface.
