HP48 Insight II - JULIA Program wanted

[Bruno]

Hi All,

I'm looking for the following program by Bill Wickes (from his book HP48SX Insight Vol2)

the JULIA program written in assembly language (see p.506, chapter 15.8.1)

Anyone have a copy of this materials ?

Thanks
Bruno

Yeah, I almost did the same thing. In the text of this section of the book, Wickes notes that "...if a person were to write this same program in assembler, it would be 50 times faster..." so Bruno is looking for someone that may have re-written it in assembler. Um...good luck.

I might have been able to do that a few years ago, but it would take me a some time now to get back into Saturn Assembly! Good Catch!

Yes, I think Bill Wickes itself write the code :

He said :

"... it is possible to write an assembly language version of JULIA that is fifteen times as fast as the user-language version. This zoom [...] was computed with 255 itérations per point..."

Since 255 itérations per point for the entire screen may require a month in UserRPL...
