Memory is now at 512MB.
I stuck a slightly bigger heat sink on the processor and removed the fan. It runs fine like this and hasn’t had any overheating problems. The upshot of this is that the machine now has no moving parts and is completely silent!
I got a very short (25cm) monitor cable from Lindy. Made the cables much tidier, but didn’t improve the screen sharpness noticeably, as I was hoping it would.
I added a speaker socket on the back so at some point in the future I can use some external (wooden) speakers without needing the keep the front flap down all the time. I removed the non-working speakers from inside.
I put in an IDE to compact flash adaptor. The adaptor is accessible from under the front flap. My plan is to use the Linux suspend2 patch to resume from an image on the CF card with the aim of reducing the time it takes to get ready. I’m still working on making this work properly.
