I’ve spent the last few days working on a Macintosh project and starting a new blog and website.
The project involved my attempt to upgrade the memory in my Macintosh SE. It has 2MB and I was going to upgrade it to 4MB. You can read more about it at the new blog (http://www.vintage.excited-geek.com/blog/), but the short story is I was not able to upgrade the memory in the SE. The memory will be used in a future upgrade to my Macintosh Plus, so it won’t go to waste.
The new website is where I will combine my vintage computer interests (http://www.vintage.excited-geek.com/) and doesn’t have much on it yet.
The new blog will be for combining my Macintosh and PDP 11 interests. This blog will continue as it is.
I list my posts to twitter @dailyappleii and @vintageeg.
you have to clip a resistor to upgrade to 4mb ram

That is true of a regular Mac SE, but mine has an accelerator board with its own 2mb ram.
If you look on this page, http://www.hardwaresecrets.com/printpage/Inside-the-Macintosh-SE/1724 figure 25 shows a Levco board like I have. It says 16MB, but mine only has 2MB, which is the double row on the front edge. It mounts on the SE motherboard using the PDS just like the Radius shown in figure 24.
