You also couldn't use the UART and the buzzer at the same time given how this machine is wired up. Hmm.
Honestly, I figure it's at least possible to write a decent monophonic music tracker program for the M100's internal speaker. Throw in a fast arpeggiator for chords like they do to save channels on SID chiptunes for fun. If I was a better programmer I'd try. :( On Thu, Dec 29, 2022 at 10:09 AM Ken Pettit <petti...@gmail.com> wrote: > On 12/29/22 6:56 AM, Alex ... wrote: > > I've got a vintage MIDI synthesizer with the exact same CPU as the > > M100.

Any resemblance between the above and my own views is non-deterministic. The question of the existence of views in the absence of anyone to hold them is left as an exercise for the reader. The question of the existence of the reader is left as an exercise for the second god coefficient. (A discussion of non-orthogonal, non-integral polytheism is beyond the scope of this article.)
