[sdiy] PIC Baudrate Converter

Hi Magnus,

>what is it, 5-6 years?

11 years ago it ended!

>But wheren't you their tech? ;)

*was*. I knew everything, but you know the saying about "if you don't use
it..." I was even on the road with it - the 1992 ELP tour used Miditaps as
the MIDI LAN onstage and offstage Will Alexander had the master unit and
made the network configuration changes during the songs. We had one stuck
note, once! At least while I was on the tour. :)

Interesting design because everything was downloadable. There was a code
loader in EE, then the box operating system in different EE, and
configuration in different EE, and when you wanted to download new code into
the box you brought it up in code load mode where it executed out of the
code loader space. Then came the time when we needed a new code loader,
because the OS code got too big and had to overlap configuration EE, so we
booted on the old code loader and loaded code loader loader code into the OS
EE, then booted on the code loader loader in the OS EE and loaded a new code
loader into the code loader EE, then booted on the new code loader and
loaded the new code into the OS EE. Sounds whacky but I just re-read it and
it's correct (I think). This gave new meaning to the "How much wood could a
wood chuck chuck..." saying because I made one up about "How much code could
a code loader load...".

Of course if you somehow hosed up your code loader code you were hosed.

Best Regards,

- Gene

*INSTANT FLASHBACK*

Wow, somebody said Lone Wolf....

Say *WHAT*? This comes after, what is it, 5-6 years?

Back in the days I was fiddeling with PAs, we where looking at Lone
Wolf along with friends. It was beeing considered for feeding the DSPs
sitting inside of the amps, so that you just tossed the signal to the
amps, and they had the cross-over filters builtin. It all dried out
since IPR/Licensing issues came up if I recall things correctly. This
is often a misstake done I guess. To get something of the road, it has
to be unencumbered by such issues, onces on the road, there are
windows of oppertunity.

But wheren't you their tech? ;)

Evil!!!! But might work! ;O)
