On a good day I mean MIPS. :-) Even VUP's was largely gone by the time the last of the VAXen were released. I hadn't heard the 1 MIPS rating was marketing BS, but it doesn't surprise me. Somewhere I used to have some pretty good speed charts with different machines that interested me, and ones that could be used to tie the different charts together. Zane -- | Zane H.
