It turns out, the greatest challenge is finding the NCP software on the host side that implements the ARPANET protocols. I have searched the TUHS archive and elsewhere, but all I find for Unix is a copy of the PDP-11 Unix V6 NCP from Illinois. Has any other NCP implementation for Unix survived? From old host tables I think there may have been some VAXen online before the switch to TCP/IP. Best regards, Lars Brinkhoff
