SE - how to do it ? Summary: Problem upgrading a new(?) MacSE from originally 1 to 2.5Mb. Keywords: SIMM,RAM,SE Message-ID: Date: 23 Oct 90 14:24:24 GMT Distribution: comp.sys.mac.hardware Organization: University of Tromsoe, Norway Lines: 19 I have tried to upgrade a new MacSE with a combination of two original 256 kb (?) SIMM bricks at position 3 and 4 - and two NEC 1 Mb SIMM's at position 1 and 2. Strapping the board for 2/4 Mb. This is - i think - how I have done this on SE's before, but on this version there were only two chips on the original lower bricket. Is this a new technical solution or what ? As this has been working alright on the previous simmilar upgrades I would like advice on the subject. Most combinations (strapping,upper/lower,old-SIMM's,...) have been tested but with no good results like 512 kb RAM or zzzzummmm.
