How to write binary in ROM???

27C series cant be re programmed unless erased by UV eraser until contents are cleared. That is where i suggested to use 27F512
Later you got 28series also.
if by any chance if you can manage serial eeproms, better chose that. there are many programmers that can load the dump cheaply.

Yes, just do a text search for the IC you want on the "chips supported" link from product page you posted. The 27C512 is there three times.

@ChrisP58,
you are right
But iyt says ith new software.
wthe OI P needs to seek new software for it and apy $38/- plus customs charges to get it. Just to to write 218 bytes into 27C512. Perhaps one time managing manual way would be cost effective and he could use the funds for a better cause.
