Help. I was just about to upgrade another SE from 1 meg to 2.5 meg using some 1 meg simms. To my surprise Apple has revised the motherboard. There are no longer two resistor locations labelled "256k" and "one row". Now there is a 3 pin header with a shorting block. The two locations are labelled "1 meg" and "2/4 meg". Assuming it is possible, how do I position the shorting block to allow a 2.5 meg configuration? (that is 1 meg simms in the "first" row and 256ks in the second row.) Stacy marsella@aramis.rutgers.edu

In the same vein, what will the SE30 logic boards look like? Will they
have a jumper? Will 1 Meg SE30's have 4 256k SIMMs or 1 1Meg SIMM?

Will 1 Meg SE30's have 4 256k SIMMs or 1 1Meg SIMM? If you look in the Feb. 89 issue of BYTE, there is a full-page picture of the logic board on pg. 114. You will note that there are 8 SIMM slots. These are populated in blocks of 4. A 1MB SE/30 has four 256K SIMMs. Dennis Cohen Claris Corp. ------------ Disclaimer: Any opinions expressed above are _MINE_!

I have heard that SE's now come in 2 flavors... the standard 1MB, and a new
configuration, the 2MB (with a 40 MB hard disk....).
My question is this.... what is the configuration like in this 2MB SE? Does
it come with one bank of 2 1MB and the other bank empty, or does it come as
a set up with 8 256K SIMMS (like the dove adapters....)?
I need to know te
The answer to this soon, as we are thinking of getting one of these 2MB monsters.
Thanks
Keith

If you are talking about the SE/30 (which I think you are !) then the 2Mb configuration MUST comes with 8 256K simms (unless you build 4 512K simms ! ) Remember that the SE/30 is a 32bit machine (like II, IIx) and therefor memory upgrades MUST be 4 simms at a time (not like the plus and SE where they need to be by pairs). Hope this helped. -------------------------- Alain Dumesny awzy@vax5.cit.cornell.edu

I got the lead on this machine from someone whe got the info from apple. He is interested in orderingsome of them, but neither of us knows what the upgradability of them is. That is why I want to know if this "new" configuration is as above, or some other convolution of memory that I have no idea exists. Can anyone tell me any more about the 2MB/40MB SE??? Keith

For a Mac Plus or SE to be 2 MB, it has two 1 MB SIMMS in slots 1 and 2. In the newer revision SE motherboard it is slots 3 and 4. You can add two 256K SIMMS to make it a 2.5 MB machine or two 1 MB SIMMS to go to 4 MB. Mark B. Johnson AppleLink: mjohnson Developer Technical Support domain: mjohnson@Apple.com Apple Computer, Inc.

Anyway. I am almost 100% sure that a 2Mb se (old !) would include 2 1 Mb simms I would be REALLY surprise to see piggy backpack boards like the dove upgrade for a machine that comes from Apple. I havn't actually opened on of this, so this is why I am 'nearly' 100% sure. (I used to work as an Apple technician at a dealer). Hope this helped. Alain Dumesny
