Hi Colin

The Din Sync vs Midi Clock port thing ...

Can you remind me if that is a user selectable option offered by the 
firmware, or is it a hardwired hardware thing, meaning you have to 
have 1 or the other ?

It is a hard-wired option. You need to add a PIC12C508 din to midi sync
convertor chip to the mainboard, plus an extra resistor, and leave out a
couple of resistors to get a midi clock only output instead of DIN sync.
You can actually leave the DIN sync pins wired if you like, which gives you
both midi clock output and DIN sync on the same socket.
The DIN sync output does not support a continue pin, so DIN RUN and CLOCK
use pins 1 and 3, midi out uses 4 and 5, and pin 2 is ground.
The only problem with this is that you need to make sure a connected DIN
sync device does not treat pins 4 or 5 as either a continue or 'tap' line -
easily done by wiring a DIN sync lead with only pins 1, 2 and 3 connected.

OK ... Sounds like the Din Sync is the standard option then.

So, if someone is buying one of your lovely fully built P3's, 
straight from the "P3 Factory", and they would like it fully PIC'ed 
up and "ready to clock" when it arrives ....

- Is that an option that is available ?
- If so, how do they get it to happen ?

Yes.

You answer 'yes' when I ask if you want clock only midi instead of DIN sync.
There's no extra cost on a ready-built unit.
I'll be charging for the programmed PICs at cost price for kit builders who
want one.
