My notes are at home, but IIRC there was about 7K available after the
data segment, executive stacks and workspace (for Hello).  Ticker went
over 32k just for the data seg, stacks and workspace.

No, but will try next time.

Actually, the 2148 has 512K of Flash, so the problem is not code
size.  There's just not enough RAM...
