Hallo Bernd Will it be worthwile? Bare in mind, the only thing you can use it for is EMS or Ramdisk. So my advice is more in the direction of compact flash. Cheaper? less risk. I have a PC3000 without memory upgrade, and no problems. So you risk your PC3000 for a 1M of mem with restricted use. Regards L.G.C.M. Arendsen (Leo) E-mail: Leo.G.Arendsen@xxxxxxxxxxx
