Questions about NeoDesk have popped up lately and with the announcement by Dan Wilga that he's released the source code for both, there will most likely be renewed interest. NeoDesk is a feature packed desktop replacement and Geneva gives it a co-operative multitasking environment. It's a very powerful combo and I used it quite a bit, back in the day.
I grabbed a backup copy I had from when I was running it around 1998-1999 and set it up on a 1 gig SD card. I ran this from my Mega STe and it booted up perfectly. I had forgotten how much I had done with it. With everything running on my 4 meg Mega STe, I still had a little over 3 megs of RAM free.
