Any design "gotchas" with the Xicor X2864 EEPROM?

Hi, All, I'm going through a box of older ICs and ran across a few X2864s. I know they are 64Kbit JEDEC EEPROMs, but what I don't know is if there are any odd issues with them. I found a datasheet that's mostly in Japanese - I do happen to read some Japanese, but I'm far from fluent. I'm mostly curious about in-circuit programming. I know a lot of newer hobby-type projects use different families of EEPROMs and that some devices can only program certain ones. What I don't know is how that relates to something as old as the X2864. I can probably program these in a standalone device programmer and potentially have to build a pin-swabber socket for a 2364 (or even 2332 for a PET), but I'd like to know if I'm opening a can of worms before I begin. Thanks for any warnings of pitfalls ahead. -ethan
