So they solved the wrong set of problems. SMIT was a force fit of UNIX to mainframe shop and never was quite right for either group. I'm not sure the IT folks really liked it much better than the UNIX folks, but at least for them it used their terminology and their concepts (*e.g.* DASD *vs.* DISK). BTW: HP, I thought had a similar issue and they did not really understand the UNIX user. DEC parts of so got it/parts did not. Many DECies wanted Ultrix == VMS (and really wanted Unix to go away since VMS and RXS were really better in their hearts), but at least there were a ton of folks inside of DEC doing the Unix work that 'got it.' As I have said before, it was always interesting having all of them as customers at LCC. You got to see the good and bad of all the systems vendors.
