He is not there, although his account is still open and forwarding mail...
isabel is still a _486/33_ although she has 32MB of ram now. I stopped
collecting byte benches some time (years) ago, I think I received about 5 in
total...

You have better disks than my old 16bit ISA.

The linux "context" has grown somewhat since 0.99

isabel was running gcc-1.39 or 1.40 at the time, it is quite a light wait
compiler compared to 2.6.x. If there is interest I'll find out what isabel
scores nowdays, it would be interesting to see what I get when booting with
ram=8MB.
