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. -- Pete Peter Turnbull Dept. of Computer Science University of York
