Not true. There are many routines that were added to the 128K ROMs that were never made available as disk patches. (For example, there are a lot of Resource Manager extensions and QuickDraw calls.) So a 64K ROM + System Disk does not equal a 128K ROM. -- Larry Rosenstein, Object Specialist Apple Computer, Inc. 20525 Mariani Ave, MS 46-B Cupertino, CA 95014 AppleLink:Rosenstein1 domain:lsr@Apple.COM UUCP:{sun,voder,nsc,decwrl}!apple!lsr
