Today in "weird stuff I forgot I owned"

The PhonePIC is a PIC programmer from the early 2000s, that allows you to program a microcontroller by sending it DTMF tones.

The board has a mic attached to it, that you hold up to you phones handset and then press keys to write programs!

I'm not sure if this makes PIC programming easier, or harder.

I /think/ the string of digits on the front cover does something like:

Set pin2 high
Set pin1 low
nop(?)
Beep once
END

I'm assuming 00=nop, I can't actually find that code in the manual

@lpbkdotnet nop = no operation. It´s widely used as a single cycle processor delay.
Btw. this reminds me on the ATtiny Audio Bootloader by lyok and ChrisMicro for the 8Bit-Mixtape by @dusjagr. Here the Arduino IDE starts to beep for you.
