These look like Motorola power transistors, but I'm not having any luck
finding information on them.

The label printed on the case is:
Motorola logo
4-611 1854-0611 = Hewlett Packard part number

OEM = 2N6055

MEX
8607

and
Motorola logo
1854-0774 = Hewlett Packard part number

OEM = 2N6056

MEX
8539

I'm guessing that the 8607 and 8539 are date codes. Maybe the MEX is
Mexico? (Assembled in Mexico, perhaps?)

The line under the Motorola logo _looks_ like a part number, but I
checked Google and On Semiconductor, and have had no luck. (Motorola's
power semiconductor business became On Semiconductor, right?)

Any ideas / suggestions?
