I have ported a version of 4.2 to the MicroVAX I & II. Unfortunately, I had to use some code from Ultrix 1.1, so you'd still need to have Ultrix. It would be nice if Berkeley would support MicroVAX in future releases... the machines are really quite similar to "older" Vaxen from the kernel's point of view (OK, so the I is braindamaged). Avie
