Is there a cheap burner that will let me read and write both of these if need be? I assume if it'll do one it should do the other and all the varients?.but I want to be sure before I buy something that doesn't work!Ģ. Ok.so, here's a few more questions then.ġ.

Hmm.I just peeled back some of the older chip and found this next to the 'ST' manufacturer symbol.Īpparently they used different chips in the past.I assume its an older variant of the m27c256b. That is on the newer chip that they sent me. Ok.they have stickers over the windows and part numbers, and I don't want to remove them until I'm able to read them! I have peeled one side back enough to see this though.
