$60 at the one in Bremerton, WA (near Seattle). Unfortunately, it was the only one there, and I've been looking from time to time - it's the first time I've seen one at any price at that particular store. I've never seen one at two of the other Seattle-area stores (it's not that I'm hanging out at Wal-Mart, it's that I'm looking for these devices specifically).
Actually, though, the Black Death has returned...sorta.
Once I'm in the BIOS, even with an El-Torito'ed CF in the slot (made with Disk Probe per the instructions at http://thinker.falcons2000.com/ia1/w2k-inst.html ), the option of booting from anything other than Floppy Drive A is not available. Maybe I'm just extra-crispy dense, but nothing will change the "Boot From Drive A Floppy: First" line to anything else. The CF looks reasonable (there's files on it according to Windows Explorer, and they look like enough stuff to boot linux), but it just doesn't show.
So, in frustration, I left the BIOS to boot per normal. It complained about invalid CMOS settings, restarted itself, and started loading the MSN stuff. I pulled the power. Now it won't boot again. Shorting the jumper to ground doesn't help - waiting several hours does. So, what appears to be Black Death is just more like a coma.
This leaves me scratching my head; what's the best way to verify that a boot CF is "valid" - ie, should make other options come up in the BIOS and let the IA-1 boot from the CF?
