I tried that, but for some reason didn't get it to work correctly. However I was also in the middle of development of the utility, so could have had some other problem. :-(

One thing I've learned about FRAM71 is that many times it takes several attempts before succeeding. I'm still working on bank-switching two HC ROM's on-the-fly, to duplicate Hans' feat.
