Quoted from uofmer:

The UV 27x256 parts are, however, all over ebay between $2 and $10 bucks, but since I don't have a UV eraser, I like the EE parts better...

You can look for other non UV DIP28 EEPROMs on ebay. 27SF256, 27SF512, 27E512, W27C512, etc.

Common 128kbit 128k Byte EPROMs are 27C010 and 27C1001 - these are same pinout, note these are 32 pin parts.
The Winbond W27C010 is an EEPROM (electrically erasable).

Sorry, that's a typo in my previous post - 27C010 and 27C1001 are 128k Byte parts.
