I noticed that you have alot of 486 SRAM Cache Chips, I have been looking for some to upgrade a computer of mine. I hope this is correct, are they for L2 Cache on the motherboard? They reason why I ask, is because that is what I need. Are they all the same configuration? ie.. (32K x8) for example. Or do you have (64K x8) or 128 versions also. Please email with Information. Thank you for your time Scott Rowe
