Ah. That's the problem with EDO DRAM chips. You really don't want to steal chips from (eg) a SIMM because the mounting is hard enough with brand new chips - with pulls it'd be even more frustrating.

Hitachi parts are ok too (the same type as are already on there) if that helps.

Edit: just found these guys:

http://www.memphis-electronic.com/datasheets.htm

...who appear to be making EDO DRAM... ie, a current product. Looking at their datasheet, it would also appear to be *the Micron part* (ie, the datasheet has Micron crossed out and Memphis written on it in crayon).

The part number is 4X16E43VTW-5 I guess. You need the 4k refresh model. Might be worth telling the Tivo guys about this stuff too, it'd work there...
