I'm working to source myself a 2Gb module. Easier than to pull a truckload
of SIMMs from the TL board. Given some time I can try a 2Gb AS4100 as well.

Sidestep: anybody ever tried an ES40 'Clipper' ? Tsunami based and max 4
CPUs. Just found one with 4 CPUs and 8Gb of RAM. Brought it down to 2Gb
already but lack of time prevented further experiments.
