Maybe not quite vintage... but I have these, and no need for them, and would rather trade or give them away than toss them. I have four memory modules labled as follows: Series 800/900 Memory 32mb A2511-69001 The extractor handle on each module (and the label) says 32mb. But being somewhat familiar (although rusty) with HP part numbers and modules of this type, it is possible that even though it says 32mb on each module that each one is really 16mb, as modules were always sold in pairs for these particular systems. Knowing the origin of this memory, it mostly likey came from a G machine, or possibly a K machine. I cant be sure, but I suspect they are working fine. If anyone wants them let me know quickly...
