Waveblaster fixed, it was a quick one…
The MC6850 was not outputting any midi signal, swapped it with a “new” one and everything is working fine now.
Luckily I have a stock of 6850 I purchased a few years back when building my own 6502 breadboard computer…

Now I need to sort out ROMs, I just realized I might have wrongly named the TOS 206 ROM file as all the burnt ROMs tells me that ST536 ROM can not run on a standard ST… :headbang:
Luckily it’s only EPROMs, so they are now getting a good sun tan in the eraser….

Thanks for testing that feature ;)

I'll have to rename the version to something else. But it probably get confusing as I think there's few versions already :shrug:
I suppose 207 or 216 or something...

EDIT: so there's a 207 and 208 already. Maybe I could start at 210....
