the bottom one is a Thomson-CSF part number.. but the logo isnt..
The Thomson-CSF logo looks like the Star Trek emblem 
but i have seen the logo b4.. so will find it tomorrow  |
found the logo.. knew i had seen it 
Sescosem was created in 1968 or 1969, then became came part of Thomson-CSF again in 1982
here is 6800 clone with the Sescosem logo http://www.chipdb.org/img-sff96800k-6701.htm
bit more info.. all gets very muddled with Thomson / CSF / SGS / ST
| Quote: | in 1968 CSF was absorbed by Thomson-Brandt, creating Thomson-CSF
SESCOSEM was also created to manufacture components, merging Thomson's SESCO and CSF's Cosem |

nah.. cos they make their own under the S-MOS Systems / Seiko Epson Corporation banner & both used the same logo.
Only reference i could find.. trying SEG or SE (the G looks like it added after) is these eProms were used in Security Electronics.. but who knows

Hello,
Probably not many of you know, that polish CEMI also produced EPROM. It was a clone of i2716 and its designator is MCY7716. It was produced it a very low quantity at the end of 80ties right before the end of existance of CEMI on the market. And here is the picture.
Best regards
