NS NOVUS PR Blank Program Form

[SlideRule]

ALL

I came across a blank program form for the National Semiconductor Novus 4525 PR calculator, BUT, as you can see from the attached {PNG format} file, the resolution is less than desirable. I have most of the artwork for a restored form accomplished and wonder if any members recognize this blank form, or, can decipher the less than legible squiggles. Any help appreciated.

Title ?
Summary? Programmer
?
?
Output?
Initialization?


Notes Stack
Key X Y Z T M? Key X Y Z T M?


is my best guess so far. M is the single memory register. But having convolved and sharpened the image it is the least clear of the columns so more a guess. I think the other column markings are just numbers for the step count (1-10, then 20, 30,,,100). It is 40 years since I programmed mine last!

I've filed it away for future use! Last time I tried plugging it in to the mains (10 tears ago?) it was still working. Have to have another look over the holidays. It was the first RPN programmable I ever owned.

Horrible trig according to Mike Sebastian's Calculator Forensics, but it got you into programming in RPN. That's a big plus.

Certainly no HP, but then again no HP price tag. I think it cost me £25 in 1976. A HP was a LOT more. Beat the sliderule and 5 figure tables I was using in college up to that point. Although we did have a PDP-11 and a few ASR-33s in the Physics Department for undergraduate use. Great days. After 18 months at Marconi Space and Defence (first job) I could afford the HP-41C. Incidentally, mine is labelled as National Semiconductor on the front, perhaps Novus was an American brand name they used?

In the States; Novus was the "consumer electronics" brand of National Semiconductor. The only differences that I've seen are in occasionally using different colors of plastic

There are other differences, such as placement and style of the NS logo, but for the most part, the distinctions are cosmetic.
