Raven 060 (sety's build)

[sety]

The MFP is responsible for placing the interrupt number on the data bus D0-D7 so possibly
PD21 (mfp<->68150)
BD5 (68150<->buffer)
D5 (buffer<->cpu)

Wow! You were right on the money! It was indeed PD21! I must have damaged the trace below the IDE header earlier in the build and after many cycles of handling and testing, it gave up the ghost. It took a microscope to see it. I added a bodge wire it and it is booting into TOS better than ever!

(I am seriously impressed that you nailed it to the exact trace based entirely on the error message. Who needs a scope? )

Wohoo awesome!

I jumped the gun and already ordered these PCBs. I have 5 here and would be willing to share 1 with the Aussie contingent if this helps. Just waiting on the chip to arrive and information on the new firmware for the chip.

Thank you! I some how missed this notification and sent it to production. JLCPCB's turn around from design to door is also faster than Australia Posts domestic service somehow.

I have 5 of them in Blue if you would like one.

The White Raven has flown the nest. It no longer needs the Falcon for file transfer. The Falcon is naturally sad, but it is also enjoying some time off.

Great to see you have that working @sety , what card did you use?

It's a 2mb Mach32. For some reason I can't get more than 8bpp without things getting glitchy, but I'll try get everything stable before I try pushing things. Still have a way to go yet

Built one! I have no idea what decoupling caps I used, and I don't really care. They look right and I haven't had this much fun since the 90s!

Just waiting for my bits to arrive. Then I'll have to work out how to program them as well. What do you use to program them?

[sety]

No idea. That would make me read docs haha... I'm guessing it is ftdi like most modern MCU

I will find out tomorrow when I get back to it

[sety]

*edit* I was wrong! It turns out you program it directly with USB. I didn't have what I've always thought was the "forbidden cable" but I was able to butcher a usb cable to do it. It reports that it has successfully flashed. I will test it when I get home
