Hi Matt, As per the schematic here https://github.com/MiSTer-devel/Hardware_MiSTer/blob/master/releases/iobrd_6.0.pdf RN1 is a 2R and a 2R is the 604 ohm resistor network. RN2 is a R and R is the 300 ohm resistor network. Each numbered resistor network has the notation of either R or 2R underneath ...

Re: I/O Board

Point of clarity on your BOM. The pdf says tested with:
R=240, 2R=475
AND
R=300, 2R=604

Should RN1, 3, 5, 7, 9, 11 be 300
and
RN2, 4, 6, 8, 10 be 604?

if not, maybe i don't follow what the spec R and 2R notations mean.

Thanks!
Matt
