Re: Gould 1604 waveform processor help..
Hello Stan,
No, I can't find any pattern, they seem random. It seems they made several keypads with different layouts but with the same functions. E.g. I uptained a manual of a 170 keypad for use with the 4070 series and did some comparison. All the functions of the 160A can also be found on the 170 but they moved the layout around, so buttons have different functions. Most of the cursor and datum postion buttons are compatible. This could be also the case with your 260. I've att a exel file which shows the differences.
I agree that a keypad works much easier and safer. So i'll have a go in constructing one and let you know how it goes. If you could find a manual of the 260 then it's easy to make one for it also....
