Wow - those TK50s are quite robust to survive being stored in the
truck of a car. I've had audio tapes that did not survive ;)

Indeed it does mean exactly that.

Yep - that is the correct method.

I thought I wrote this up at one time but I may have only thought

Is it in one an Appendix to the "Setup&Installation" document?
In the case above it is OV6 (overlays are numbered from 1) that is
The rules are:
1) BASE can be 56kb (57344) max
2) OVerlays can be 8kb (8192) max
3) There can be no 0 length overlays (except for the very

Look at the Makefile - you should see a line that starts "OV6=". Do
a "size" on the .o files listed for OV6. Pick one that will fix
elsewhere - I'd suggest OV5 since it is only 4864 bytes and has lots
of room. You could also move a .o file to the BASE since it has
adequate room also.
