EPROM Replacement Question

So, I have a box of eproms in front of me and am wanting to identify the correct ones. I'll be replacing two chips with these on my TKROM board.

PRG - 256k
CHR - 128k
I am messing around with this TKROM board - http://bootgod.dyndns.org:7777/profile.php?id=82

What would be a potential part number for replacement?

27C256 & 27C128?
I have 27C128, 27C256, 27C512, 27C010 & 27C020 right here.

Flame on! (ha!)

Takes less time to find a chart than it does to even get to these forums.
