gibs, many thanks for your test, this was very useful.
About the clock:
The year is stored differently between real hardware and WinUAE (I reported that fact there
). I fixed that, it will work fine in next snapshot.
About the FastRAM:
As Toni indicated, the FastRAM on Blizzard 1260 is not a standard AutoConfig RAM expansion board, so I don't know how to find it. As indicated, the solution would be to look at Linux/NetBSD sources to see how they solved the problem. I'm not going to spend time on that soon, any clue will be welcome.
About the keyboard:
Investigating right now.
