Difference 23512 and 27512 Eprom

[Stefan]

Hi,

I know very little about electronics and eproms so this question might be 
really easy. I would like to know what the difference is between a 23512 
eprom and a 27512 and if there are any differences if its possible to make 
some sort of adapter. Had a look at some schematics and they looked the 
same to me, data lines on the same pins etc.

Any help is welcome.

Ow the reason I want to know this is that I want to read some old roms in 
my EPROM reader.

Cheers,

Stefan.
