I finally had time to assemble my latest pet project (after my Duo 2300c):

1400c/133 with:

400mhz Sonnet Crescendo G3/1MB L2 Cache, which seems to be running stable. I had problems with this module in my other 1400.

48MB RAM

2GB HD

Ethernet Card

Working batteries. One of these got over 3 hours (though it was just sitting idle at the desktop).

Installing 8.5 now, will try some old games tonight or tomorrow. Also I'll run battery amnesia. The ethernet card makes this way more useful -- I can keep it on my desk for SSH, AIM, even light web browsing!
