I've had a little time to play with these, and here's what I've gathered so far.
1. They're a helluva lot easier to crack open than an IA-1
A precision Philips and flat-grip pliers (for mounting screwlets) did the entire job. No prying, no cracking.
2. There IS a clear jumper!
The big one, folks. There is a jumper for it. But with no CF slot and no way yet to break into the BIOS that I've found, I'm not about to nuke the thing.
3. It's mighty cramped in that thing
The plastic cover is for aesthetics - inside is a smaller metal cage encasing the whole unit. Forget internal storage. Just forget it.
4. I do believe it's got clockspeed jumpers
I'm still searching for the last of these, but printed on the PCB is a range of multipliers from 2x-10x (IIRC). I don't know about the possibilities of CPU replacement yet - it's cramped (#3) in there, and they're already using thermal paste to cool the CPU and northbridge (which is attached to a metal shield/heatsink inside the major case)
5. Riddle: What has 160 pins for cables and nothing soldered to them?
The board of an EZNET. 160 of these little buggers, arranged like so:
From what I remember, that's how they're laid out. Any ideas?
Just my update. Enjoy.
