Just making a note of the changes to a future revision C2.
Changes are making some of the text lager and "grouping" text to header in a outline box.
EG:
Audio fix
100K resistor added to correct biasing issues (causes fading YM audio volume)
New HDINT pad. Easier to solder & locate for the HDD INT wire..
There are currently no other intended changes at this time.

Re: H5 REV C2 CHANGES & FIXES
I think one of the annoying things is the jumper for flashy clock. So I have just added a simple solder jumper for this out of the way of the socket.
A jumper for the RTC might actually be beneficial as well..

Re: H5 REV C2 CHANGES & FIXES
Silk screen updated to show what the audio header has.
Load resistor added to the 32Mhz which was causing clock issues for someone (forget who sorry).
Added pull down resistors to solve audio issues when not using the MIDI synth board.
AUX FLOPPY POWER connector had 1mm holes. I have upped them to 1.4mm as I couldn't get my floppy cables in the holes very easily.

Fixed the hole sizes for the rear DC power jack. They was 0.8mm and too small for the intended connectors. So been increased to 1.2mm (legs measure 1mm).
