Chris Scott,
Yep, that's what I'm talkin' about. :-)))
MH +/- RB=MB ? I'm going back many decades so I won't vouch for the accuracy of my recall. But...I just never wanted to work that hard.
Along came the ADF with an RMI card and I was saved !!
Truth is, we just don't do all that much ADF stuff here in the States anyway but those unreasonable people at the Puzzle Palace wanted to see you dance the dance...so we did.
