The shifted shifter label is a joke right? 😉

Anyone done this? Otherwise, I'm afraid it's going to have to be me... I've already prepared a rather long list of caps for my two 1084s and thinking of adding the alpha parts to that list and order it in one go.

The list keeps growing with other things, might never get to the ordering phase if I don't get a grip on myself :lol:

Not much use if everybody else already ordered their parts. Have they?

I pretty much ordered everything from mouser except the stuff I had on hand. I ordered extra of most thing. For next board I could make a parts list.

In addition to the 2K2 resistor arrays, did the 1K ones (two of them) become 4K7 as well? I have only 4K7 and 10K sils in my kit.

I'm using 2.2k for all up's except rp1 and rp7 which are both 1k. There are 5 10k resisters which were added to U14 pin 6,10,8,4,2 to +5. Board has been totally solid, powers up running and I have no issues.

I listed 2.2K as the main ones (address & data bus) , but later changed my mind to 4.7K... I think the 10K one is on the DMA databus pins.
