If there's no label on the module identifying the size, it's really tricky but not impossible to ID them. Typically the chip would have numbers like 4096-8 which would indicate 4 megabit (DRAM chips are almost always 1 bit wide per chip) and 80 ns not that it's useful for Duo. Then count the number of chips. if there's only 8 chips, then it's 4 M x 8 bit or 4 Megabyte total. 8 chips would mean 4M x 16 bit or 8 Megabyte total. Some chip may use 4000 instead of 4096 so don't be fooled by it. You probably won't see any chips smaller than 4000 x 1bit as Duo RAM were never offered in size smaller than 4MB. Some chip manufactors don't use this scheme so you'd have to search through the chip manufactor's site for chip specs. Or just post the details here and some experts or someone who already have the same module can tell back. ---------- Duo/2400 List, The friendliest place on the Net!
