I managed to get V2 boards a day early and really early. Like check tracking when I got up and "Delivered: 6:54 AM".
Electrically they work 100% fine. No need for bodge wires to make them work! 680 ohm resistors have gotten the 7404 to work properly, no matter which variant you install. You'll notice some bodge wires here - that's playing with current handling. Using just the fairly small PCB traces, I can power a Mac IIci, Supermac Spectrum/24 PDQ, RasterOps PaintBoard Li, Toby video and a single 3.5" Quantum hard drive. The voltage starts to sag quite a bit though - getting me barely ~4.7V. That's not good enough. Add a 2nd hard drive and it'd drop below 4.6V and the system won't start.
The patch wires there are just for extra current handling. They're 20 gauge copper so not terribly big. With these I can run all the above plus a 2nd hard drive and still get 4.8V. The next board revision will have planes rather than small traces and should help significantly.
As for the placement, the board now has the 10 pin on the opposite end of where it was before. This allows it to plug into a IIsi motherboard directly. There's plenty of clearance between it and the SCSI connector so that won't be an issue.
The next thing are the LEDs. Doing some testing I had with random chinese $0.01/ea LEDs, 4.7K worked great. Of course, we have higher standards for actual stuff and called for Cree LEDs (~$0.10/ea as singles, not a huge difference). I've got some of the red Crees but they're way too bright on the 4.7K resistor off the 5VSB rail. Upping it to a 10K helps, but the LED is still retina searing bright straight on. They really don't need much current. We're going to grab some Lite-On LEDs and hopefully they'll be somewhat worse LEDs. I mean that in a good way. Picture below has Chinese Green old school tech in front, Cree in back, both on 4.7K resistors on a 5V rail.
Next board will be ordered Soon(tm). It's going to move +5V and Ground to planes, clean up the resistor placement and include standoff holes. If it works fine and can handle heavy loads, it'll become the final revision.
Overall, project's going good. Here's a pile of test boards I've built
