I ran make tod81 but there were errors and it looks like 11.D81 didn't get written. For every file I got output like this:

c1541 -attach 11.D81 -delete 11.parse -write 11.parse
deleting `11.parse' on unit 0
Error - Track 0, Sector 0 out of bounds.
ERR = 01, FILES SCRATCHED, 01, 00
writing file `11.PARSE' as `11.PARSE' to unit 8

I can't figure out why that's happening. @gurcei - If it's not too much trouble maybe you could try running that tod81 task on this branch and see if it works?

Edit: I just checked the actual 11.D81 and it does have the updated version of 11.parse. I just assumed that it didn't work because of those errors and because the diff here is showing 0 bytes changed. Maybe you get these same errors when you build the D81?

Ah yes, I also see that error on my side, I just got so used to ignoring it. Maybe there's something amiss with the directory structure on the existing 11.D81 disk and maybe I should try do a COLLECT and see if it makes the problem go away.

So for now, just ignore the errors and hopefully we can get this resolved later somehow.

Thanks for the PR, looks good, will approve and merge it in :)
