First is this MediaGXm
Laser marked on the front, with 2 production codes on the back
GXm 266MHz @ 70C
V3SE3833AB
V3SE3911A
Thats 6 months between them, maybe retested later?

Next up we have this oddball 6x86MX
Cyrix 6x86MX-PR166 60MHz 2.5X 2.8V
The back is laser marked
GEDD7724B
There is also a serial # laser engraved on the top ceramic as well
That makes it one of the very first 6x86MX processors i have seen, its also a 2.8V part whereas production ones were 2.9V

One of my first ever eng. samples was this Cyrix. Seems like the ceramic engraving style is the same and also the number "135"
