I remember that the real heart-wrench with the BBC Micro was when Acorn announced that spare parts would no longer be available. I'm sure that Castle will still stock and sell us the bits needed to keep the old machines ticking over for a few years yet. It's a shame the Kinetic upgrade is still so expensive - all those 1000s of RiscPC 600s and 700s would get such a boost even at this late stage. That could be a cheep way into RiscOS now; source a cheep PC700 and StrongArm it. Perhaps it is the StrongArm itself that is one of the hard to source parts ?
