Go carefully there. Kynar tends to wilt at soldering heat. Press insulated wires together when they're still hot and suddenly they can be kissing; a 1-diameter short is easy to overlook when you're inspecting your work.

I find it worthwhile to use teflon-insulated wire here. When I'm building a prototype, the last thing I want to have to distrust is my construction.

Try 1972; taped out in 1971.

So it was double-forks, not pitch-forks, all along?

That's Keith Baar; I looked it up.

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.

> The 8088's chief virtue was that it was readily available at a reasonable price;

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."

If you come across a CZ230S, be aware that you can exfiltrate all 100 of the fixed voicings through SysEx. I got that far, saving those tables to disk; my plan, when I ran out of time and attention, was to SysEx in one of those settings to the last entry in the CZ101's table, which is overwriteable, so as to get 8 notes at a time. Maybe you'll find a place to drop in a ROM with them all.

Thanks, CVS.

It's off the shelf at my local CVS (e: and has been for weeks). I looked.

My anecdata is that, though it's not as effective as pseudoephedrine, phenylephrine actually is effective in an inhaler, and a helluva lot better at clearing up a stuffy nose than "scents and essential oils". Of course, a cylindrical inhaler with a wick inside it doesn't go near my digestive tract... Now I'll have to look around for a replacement inhaler, something quick enough to avert choking-panic. Thanks, CVS.

> makes it impossible to just plug in some perfboard with headers on it and make your own shields

Not so. You just have to drill ten holes, using another piece of tenth-inch perfboard as a drilling guide. I've done it; it works.
