[sdiy] just when you think DIY spirit is fading out

[Mike Bryant]

A PDP-11 in Southampton Uni was the first time I programmed a synth in software.  Nowhere near real time, but it had a couple of oscillators, a level envelope and a simple digital filter (which were almost unheard of back then).  Output was a file that I programmed into a 2708 EPROM and then played back on some homebrew hardware and a discrete resistor 4 bit DAC, varying the clock frequency to set the note.

What can you say, everyone needs a hobby.

There are people that do things the old ways in a number of fields just because they like too. Some people look at synth DIY and say why not buy a box or use a soft synth.

Then there is this. I'm going for a PiDP-8 sincethe first computer I programmed was a Classic PDP 8 and I worked for DEC for a bit.
