It looks like TCS 4.0 is in the process of being released. I happened to check the TotalService site this morning and found updates for the HiperARC, HiperDSP, 16 Meg NMC, and TCM for Windows, HP and Solaris (still no Linux). The link for the new HiperARC Manager software is broken or the file isn't out there yet. Since I still have older equipment (quads and dual-T1), I probably won't be upgrading right away. The compatibility matrix had not yet been updated. So, who wants to be first?
