Have done a new version on my MIDI hat with DAC and OLED display for the Raspberry Pi and MT-32 pi MIDI hat.jpg MIDI hat (with DAC).jpg MIDI hat (with DAC and OLED).jpg As of version 0.8.0 of MT-32 Pi, I now need to look at adding some buttons: https://github.com/dwhinham/mt32-pi/wiki/Control-surface

IC22 was soldered in as shown previously which was confirmed as the correct orientation: https://www.exxoshost.co.uk/forum/download/file.php?id=15655 and yes, have the Flashy socket jumpered: flashy-jumper.jpg Was also wondering if I had not cut the track under IC6 properly and this was still connec...

H5 A3 board #1 powered on with diagROM in socket... Reset switch does not seem to cause board to reset. Switch itself is working (5v/0v) but board shows no sign of reset. Output to screen is a white screen. I did get DiagROM to boot once and show the menu so I had life once and reset switch seemed t...

... so far the shifter is proving to be the trickiest to source so I may have to bite the bullet and sacrifice at least one of the other potential RIP boards to let me prove the functionality. There is someone here in Australia selling shifter ICs: https://www.ebay.com.au/itm/PH23-024-C025914-38A-A...

Finally found some time to get board 1 moving again and now have all the fixes done and some DIL sockets in place, including the extra bodge wire where I broke the 2nd track.

I am pleased to advise, I only seem to have cut the 2nd track. Tracks 3 and 4 pass continuity test. Phew. Only 1 long bodge wire to add and the original fix wire on this board.

@kodak80 - I did the same and cut too many.

Let me find out the tracks for you.

Thank you. Will be good to see how much I broke...and needs fixing.

So, I may have filed too far on the "SIDE0 FLOPPY SHORT FIX" and I have cut the next track above and may have cut the other 2 tracks above that. Can anyone confirm what the other 2 tracks connect on the board so I can test continuity of these other 2 tracks? Side 0 floppy short fix (filed too far).p...

Thanks for confirming @Icky. I could not find anyone photos on H5 boards already built by the group so far but checked my H4 and the tracks helped even though the IC is now rotated compared to the H4.

Whilst others have began the race to build the B1 boards, I have 6 of the H5 A3 boards so I have started building the first one to get this up and working.
