Errata for On Rope (1987)?

Finally obtained an old copy of " On Rope ." It's the old 1987 version (1992 printing). I paid a whopping $6.50 for it. Is there perhaps an errata sheet for it floating around on the web? I haven't noticed any obvious errors yet but it might be nice to know if any errors have been noted. Thanks.

Edit-

Fig 11-20e on page 295 looks slightly wrong.
