I have no recollection of what I wrote here or why I
erased it. My best guess is that I moved it to Micros.

Depends on your application. The Raspberry Pi has more
processing power and storage than an Arduino would but it
also draws more current and is probably less stable, in part
because of the complex operating system.

Pi has a number of deficiencies in the platform. Limited storage
options and Ethernet over a USB bridge make it slow getting data
off and on the machine; complex DRAM architectures make hitting
tight timing deadlines hard. I wouldn't say that it's less stable
than Arduino, but one can't make hard predictions about performance
and for non-realtime stuff, it feels kind of underpowered. For
many of the applications people are using it for, I think something
like the Banana Pi M1 or M2 Ultra or Cubiebox are better choices
(real Ethernet and SATA). For something where you have a hard
realtime requirement, Arduino may be OK; Beaglebone with the PRU
is in many ways better.

It's on Mouser, but it ain't cheap.

I have been experimenting with a Raspberry Pi 1B and its
composite video output (set to "progressive NTSC" and 16:9).
I didn't expect it to play video but was surprised it's not
able to play Ogg/Vorbis or MP3 files smoothly in NetBSD/evb-
arm. I should probably recode some music into 44.1 kHz .au
files to see how that goes.
Linux fares better, presumably because it has binary
drivers for some hardware acceleration. I can play postage-
stamp QSIF MPEG files and MP3 audio. If I find the right
composite video cable for it, I'll try NetBSD on a Raspberry
Pi 2B.

Cool. I should check out RPi sometime.
Are you trying to build a computer you can use for some purpose, or just
experimenting to build your arsenal of knowledge and experience?

I have a few uses in mind but it's also to familiarise
myself with the limitations of the device (and of my OS
running on that device).

Have you fared better with the pi3b?
I'm using one for a 'land rover' remote exploration in the Mojave

I use NetBSD/evbarm 9.2 on my 2B and my son runs
Raspberry Pi OS (Linux) on his Pi 400. NetBSD works better
than I expected with the exception of sound, which doesn't
work for more than a few seconds. My 2B is a slightly
different version than the NetBSD dev. has so of course it's
working on his board and not mine. I've learned that
replacing the kernel on a Raspberry Pi is a lot more
involved than I'm used to on other ports.
