My soldering iron is even bigger :)
Hey, don't be startin' a size war with me: I'll get out my gun
(Well, strictly speaking, it's my mother's gun, since it was part of my father's estate. I've forgotten what the rating on the heater is, but I think it puts more watts into those two little bulbs that bracket the tip than a Metcal puts into its heater...)
I botched my first attempt at modding the board, but learned a couple of things. First, the net is an even more bountiful source of misinformation than I thought: I managed to find an official Realtek datasheet for the 8019 that's incorrect (to be fair, it's marked "preliminary", but now I can't remember where I got it, to warn whoever's hosting it that its pinouts are bogus). Unfortunately, I didn't notice this until after I'd clipped pin 65 from the chip, and attached the resistor to pin 64 (I'd assumed you'd made a typo. Oops. Good thing the boards are only $3 a pop...).
The second conversion went okay, but I needn't have bothered: it works (or, rather doesn't work) just like the ones configured with the DOS app: Bill's kernel says "wrong signature", and scratchy's says "eth0 not found" (It might also mention the signature problem, but it would've scrolled).
I tried one of the UMC cards, and Bill's kernel recognized it. But pings gave the same sort of errors I got trying to NFS boot with Scratcy's ROM.
What PCB version(s) do you have? Maybe there's something different about mine (Rev .01).
Or maybe they're just cursed
