7747 Bad Dumps checksums

[CSH-HQ]

This error was caused by an early version, of one of the chip editors.
Possibly one involving graphiscs.  So beware with all the 7747 bins ya got.
I'm just relaying, an e-mail, and have no personal experience with how this 
happened, othr than some time ago LL pointed it out, but with out the effect.  
  Would this be the 747 idle bug, or is that something else??
Grumpy
  
Anyone still have the url for the P-Brain, for doing the 68HC11 motorola 
programming, and simulator stuff for it?.  Was like $130, with RS and 
asssemblied.  
  Off list resonse fine.
