I assusme you've seen the Elektor GBDSO project?
(Game Boy Digital
Sampling Oscilloscope). Looked interesting, but too proprietary for my
taste (no sources for the firmware are available, for example).
My thoughts exactly. I don't usually build stuff when the firmware sources
are unavailable. It also seems to be quite limited - high AF at best, not
much good for anything other than debugging audio gear.
Has somebody done a logic analyser for the Gameboy? Or
is this just an
idea of yours?
It's one of my ideas. My HP 1651B keeps running out of sample RAM on fast
signals. I think 64kbytes should be enough :)
I'm also toying with the idea of building a 40MHz version of the GBDSO. The
hard bit is finding amplifiers that are fast enough, and learning about the
analogue side of things - I've never really done any analogue design.
Later.
