I recently booted up my VS4000/90 to play with NetBSD. The CPU seems a
bit faster than my Amiga 3000 with WarpEngine 40MHz 68040) and it has
the benefit that it can do a complete build without failing, while my
Amiga has some intermittent RAM or bus corruption that causes random
GCC build failures every few days (especially frustrating when it
takes 4-5 hours for an incremental build to proceed to the point where
the previous build crashed). The SCSI controller is slower than the
Amiga (it appears to be limited to 6.25MB/s transfers) and the
Ethernet seems a bit slower as well, but the VS4000 is quite solid.
