Alright! I apologize for the delay - had to get the new boards from PCBWay and did the cheapo shipping. Anyways, I believe I have it all together. I have double checked all my connections and everything seems fine.
One feedback item I would give is that the cap slot there on the side of the PCB is pretty tiny for an 0603 sized cap. I would recommend anyone to go up a size or two, it’s otherwise just a really hard little bugger to get in there and keep situated. I did get mine in there, but took a pad with it. It’s all fine in the end but a bigger component would had made that easier.
Otherwise, wow. The plate on the back there fits like a glove and I am thrilled to be at this spot. However, will this be enough? Will the i486 DX4 Overdrive PSU circuit work with this cheapo un-branded 45$ Nvidia 5500? Will it accept 5v signaling? Time will tell if we see any black smoke.
I’m kind of afraid to turn it on, despite checking all my connections. I might table this for a bit, to do some research on the 5500 Nvidia chipset to see if it’s 5v tolerant. I’m hopeful, but maybe I don’t want to fry my retro PC just yet. :3
The PCB I made there tho seems to be perfect tho! Definitely the right move with all the feedback items ya’ll gave me, with widening the circuit pathways and getting room for a heat sync. The mounting angle is also very intentional, so that hot air rises and bring in colder air underneath it.
I’ll let ya’ll know how it turns out though. Gonna go back to coding for now.
