I've seen this a couple of times too.  If this is the case then you're
toast.

I was lucky enough to get into the game in 1979.  A friend of mine
bought one of the first Apple II+'s sold in Montreal with the money he
earned with his summer job.  32K, a B&W TV and a Radio Shack cassette
tape recorder and we played Lemonade for hours on end.

The next year he added a Disk II just before AppleDOS 3.3 became
available.  a few weeks later, when he found that memory became a
problem he then added an additional 16K to max out his system.  At
that point he also bought the newly released AppleDOS 3.3 and
enhancement kit.  Along with the 16 sector ROMs the kit also came with
a sheet of small red apple stickers with a white 16 on them.  This was
intended to mark your 16 sector disks from your 13.  I guess I was
pretty lucky to have seen that part of history.
