HI! 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 about it ;) 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 too big. 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 last one). 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.

Yep - I have a lead (not too surprising since I wrote the program :)) I think the program's present in the PUPS archive in the top of the 2.11 tree area but it may have been relocated or whatever over time. Here's the program - it should compile on just about anything that has the 'mtio' ioctl functions. It is very similar to 'maketape' (intentional since makesimtape.c started out as a copy of maketape.c).
