The EPROM lot you got are programmed in U2L8 format that was used by most MLDL/EPROM boxes between 1980 & 1985.

Here is a slide which is part of my HHC2020 presentation (if there is one) that show the format.

Thanks Sylvain,

I will keep an eye out for one of those. In the mean time if anyone who has one of those boxes has an interest in extracting any of the roms let me know. I would be happy to ship them.
