I'm in the process of upgrading my 386 AT system with more memory and when hunting for bargains I've come across types like (standard) 41256, 21256 (on the motherboard of my current system), 4256 and 81257. Which types are compatible with each other? --Soren -- ---- Soren Altemark, Swedish Institute of MicroElectronics, IM PO Box 1084, S-164 21 KISTA, SWEDEN, Phone: +46 8 7521173, Fax: +46 8 7505430 E-mail: sal@nmpcad.se or {uunet,mcvax,munnari,ukc,unido}!sunic!nmpcad.se!sal
