Summary: Hypercharger and increased memory. Message-ID: <622@bucket.UUCP> Date: 10 Dec 87 01:15:49 GMT Organization: Rick's Home-Grown UNIX; Portland, OR. Lines: 20 One of the guys at work bought an Apple SE with 1 Meg of RAM (4 256K SIMMs) Wanting more performance he also purchased a Hyperchager 68020 upgrade board with 1 Meg of RAM installed. With the release of HyperCard and Multifinder he quickly found out that 2 MEG of RAM was not enough. So he ran down to the local APPLE dealer and had two (2) 256K SIMMs removed and replaced with two (2) 1Meg SIMMs. His total RAM in the SE box is 3.5M. After firing up multifinder he finds that only 2.5Meg of RAM is available, NOT 3.5Meg of RAM! The Hypercharger user manual says 3.5Meg should be available. The Hypercharger technical installation manual says 2.5Meg should be available! Its all because of the 68020 and its need to have 32 bit words. Mac II owners run into the same problem. We should have caught it before it got too far as we were going through the same growing pains with the Mac II. SE owners with a 68020 upgrade card beware! Check with the manufacture for complete technical details before you spend your hard earned money. You may end up paying for 2Meg of RAM and only be able to use 1Meg of it.
