Actually, quite a lot of them do have info (if sometimes well hidden) but
some -- Intel comes to mind -- aren't very good about keeping old stuff,
and Toshiba are pretty hopeless. I needed some other info from the same
data book that those EPROMs are in, a few years ago, and ended up phoning
Toshiba to get it. Turns out they stopped making EPROMs about a year
before, and no longer had the data sheets themselves! Luckily one
particularly helpful customer support person found me what appeared to be
the last copy of the Data Book.
I was very glad I checked, because there are two common pinouts for EPROMs
in that sort of size range. Most manufacturers distinguish them by either
using the last four digits in the form "1024" or "1000", or they use "1001"
versus "1000". Except Toshiba -- where others used "1000" they used "1001"
and vice-versa.
