Keith Barr focused on musical technology at MXR, Alesis and eventually Spin Semiconductor. His legacy is MXR pedal effects like the Phase-90, the MidiVerb digital reverb series and the Spin FV-1 digital reverb chip.
That, and it had a compatible suite of peripheral chips, while the M68K didn't... Something I vaguely recall an Intel FAE gloating about soon after: "And we're going to keep it that way."
Use-cases? Remote and while-you-wait work, RS232 and ethernet test console. It's bigger than a netbook but it's what I've got, so I lug it around.
I'm a ham; my kids aren't... but they grew up with me using Morse (my computers talk to me when they boot up, and when a 'kitchentimer' goes off, and...) so they were naturally exposed to the paradigm. Maybe that's a limiting factor, but...
With CW you're limited to two states: key and unkey. Knocking on a wall, you're not: you can go loud and soft as well. A dah has the same pacing as it always does (3 dits in length), but if its knock is perceptibly louder, at least twice as hard as a dit, in practice that seems to make it hold together as readable Morse, at least for us. Certainly our family signal, questionmark (..__..), is usable that way, so is each son's "call-letter".
Me, I'm gonna treat it like a firstnick.lastnick format when it arrives at my account. I figure "crb3.cdp1802" is very unlikely to be taken before I get there, but, if I'm wrong, there're lots of other already-memorized device-numbers I can append.
My first CP/M computer was an Ampro Little Board 1A, sold along with a floppy carrying CP/M-2.2 + ZCPR3. I got a lot done on that machine, including a text-mode MIDI editor-sequencer -- the Z80 DART as set up could run the second serial channel (the first was CON to the terminal) at the MIDI baudrate and slave-interrupt to derive its MIDI Clocks from a sync-track recorded/played on a 4-track cassette machine through a Kansas City tape-modem.
I watch slashdot via http://alterslash.org, and occasionally (very occasionally) drop into the main site to add a comment. Are they still adding hot grits to Natalie Portman? Watching just the top comments on AlterSlash, I don't have to care.
It's my HP41CV that basically never gets used. Back when, I wrote a program on it, 'ampsr', to calculate ideals and then find the closest standard-value matches for a three-resistor attenuator network used as the gain-and-offset control of an opamp amplifier; it took 16 minutes for my HP41CV to arrive at the answer, and that was just selecting among the E24 "5%" standard-value array. My later Perl version, by comparison, is all but instantaneous even working with the E96 array and running on a 400MHz box. The HP41CV's programmability was great for its era; not so much, now.
