HP28S screen noise generator - Keith Midson - 02-18-2012 Hi all, following on from THIS thread, here is the HP28S program that produces a hypnotising screen display: Re: HP28S screen noise generator - Gerson W. Barbosa - 02-18-2012 Great for "I'd gladly lend it to you, but it's gone wacky!"

Re: HP28S screen noise generator - C.Ret - 02-19-2012 Many Thanks for remember me bitmap screen plays on my old HP-28S. If my memory don't abuse me, this code may not run on HP-28C due to the use of the XOR on strings. XOR function may not handel binary or screen strings on HP28C; only integers and regular binaries. In your code, I still not understand why you loop 738 times ? Is there samething I miss interpret, is ther any effect I miss ?
«(what a bunch as TEST ?)
Please consider my translation of your code without any use of any global variable. My version directly use actual screen apparence and loops until one key is pressed. « Great effet HP28S feature, isn't it ? May same one bring down a version for HP48/49/50 ?

Re: HP28S screen noise generator - Keith Midson - 02-19-2012 That is a much better version of the program - thank you! I have long lost my original code from 1990, which was much neater - I wrote this in a hurry to see if I could replicate the effect all these years later. Re: HP28S screen noise generator - Gilles Carpentier - 02-19-2012 "May same one bring down a version for HP48/49/50 ?" Hello C.Ret... I don't understand the prog HP28 here... On the 48/50 bitmaps are special object and not strings... Some ideas on 50G :
