I have brand new, still in tubes Fujitsu 1x4 Zips Page Mode (128MB worth of chips) and used Micron 1x4 Static Column chips (16MB worth of chips). You would beed Static Column type only if you use the on-board or any other 030 cpu that can do burst mode. For anything else, 040 and above...Page Mode.
If interested, make an offer per chip (each is half a megabyte in size)
