Hmm... Not sure of the real benefit since I don't own a HP 200LX, but some people have upgraded to 128MB of DRAM.
I read that the DRAM
(RAM area
) is used as C drive in 200LX. I guess other people know more about than I do. I believe it has something to do with speed.
Japanese page of 128MB DRAM upgrade:

Some more information here:

"Two DRAMs on Side A of the board are 32 MB, and four DRAMs on the same side are 64 MB. Two DRAMs on Side B on the back side are 96 MB, and two more DRAMs on the back side are 96 MB. Two DRAMs on Side B on the rear side
The goal is to achieve double-speed operation, but the guarantee is not yet achieved. The goal is to achieve double-speed operation, but this is not guaranteed.
The components are DRAM
(13165
), NAND logic IC
(ALVC00PW
), INVERT logic IC
(ALVC04PW
), pass-controller
(104
), and 36-pin connector.
The circuit boards are for the old and new 200LX, but the tantalum capacitors on the mother board and the DRAM may interfere with each other even in the 100LX, so if you move them around, you can use them in the 100LX as well.
If you move the DRAM, you can use 100LX with the maximum capacity of 96.5MB. However, it seems that an older version
(Ver1.0
) of the driver is required." - quoted from Site 1
