Speak of the devil times two, Don S. pointed out a sealed pack of 20 available on TAS for under $1 per card. On their way soon!

Among the bundle of HP41 manuals was an Owner's Handbook and Programming Guide. I already have one, but what was taped into the back page caught my eye. Here, in case you've forgotten, are those all-important support numbers
