Even if he finds the pinout, and even if the devices actually work, the real fun is going to begin when Thomas finds out that these RAMs are more than likely way too slow for his DS89C450. Unless he's running it super slow and/or willing to put in a lot of stretch cycles (which most people using a DS89C450 probably aren't), he's going to have issues. I hope I didn't write DS89C4x0 anywhere - I intend to use them for an 80c32 / 80c320 board. Since it will be my first step into building a system with external PROM and RAM, I can live with a low speed. /Thomas My apologies; I incorrectly assumed that this was continuing work on your DS89C450 project from last week. Still, be careful with that RAM... it might be slower than you think. --Sasha Jevtic |
