I was looking around the basement and found four sticks of this. It looks like ram but it doesnt fit any of the old pc in the house. It is too long to be for a laptop but too short for a desktop. Maybe its not even ram. It is 3.5 inches long by a little over 3/4 long. It has 29 pins on each side. There are 9 chips on only one side of each stick. For all i know its not even for a pc. Any help is appreciated.
Attatched is a picture of it

More specifically, a 4-megabyte 30-pin module with parity and 60-nanosecond response time.  Four of these would bulk up a late-386/early-486 desktop PC from the year 1991 or 1992 to 16 MB of RAM.  I once had a Packard Bell 486SX/25 system with 4 MB of RAM which would've accepted these modules.  I miss that old computer.  Good times.

As Dolly Parton sang "In the good old days, when times were bad !"


I had a 386 around about then - 40 Megabyte hard drive and, I am fairly sure, it was 16 KB of RAM. Just about the first thing I did was change the hard drive for a whopping 640 MB model, and that cost me about £UK 100 back then. Still, that 40MB HD held DOS 6.20, Win 3.11 and MS Office 6, with about half a meg left over for headroom and my work.


And now I have a desktop with 12GB of RAM and 2.5 TB of storage on the Windows side !
