My order has arrived today.

Is there a BOM available yet? I've probably got it all but the CPLD socket I think.

Thanks @PaulJ

Hoping mine will be waiting for me when I get home tomorrow, then I can get the parts ordered, though I'm confident I will already have some.

Got my boards, here when I arrived home earlier. Got my gates for the DMA fix too, so something projects during periods of social distancing.

@exxos I'm just ordering parts I'm missing for my V1.1 ide boards, and I notice the resistor networks (RN1 & RN2) are 68R on the V1.1, whereas they were 100R on the V1.0.

I have a couple of spares left from last time I was intending to use, so I wanted to check if the value had changed before I went ahead and ordered the 68R ones as per the V1.1 BOM.

Thanks.

It doesn't matter much. Though I am going with 100R...

@exxos Cool, just need to get them for the 2nd board, though I do have a load of 100R resistors so that's also an option.

I did put 68R in my board, but when I worked out the thermals of the 0805 on a short circuit, they were over-spec and would likely die. So 100R is about as low as it could go anyway. 220R may work as well, but not checked the signals on those.

@exxos mine will be socketed, so I can replace if necessary. The 100R arrays seem to work fine in my beta boards.
