[sdiy] IC Prototyping was: SSM2040

[JH.]

And don't forget that someone has to buy the *process* technology of these 
old SSMT / PMI chips, too!
(If he thinks the discrete version isn't close enough, that is.)
(But wait, PMI has been bought by Analogue Devices, and it's no coincidence 
that the AD transistor pairs in the MOTM-440 all have a "SSM" prefix ;)    )

Very cool. Ok 5 guys with $2K each...
Oh yeah, someone has to design the things...
THEN we start a company and bring Analog/Modular to the forefront... :-)

So the next kind of 'bulk buy' that we'll be getting into is getting
together to get a run of 2040 clones made?!

If we go down that road, there's ALL kinds of possibilities...
