There were Itanium workstations (https://www.openpa.net/systems/hp_i2000.html, https://www.openpa.net/systems/hp_zx2000.html), but of course these quickly crashed and burned with the rest of Itanium
That still seems weird to me. If I had to rely on a PC for high-end work in that period, I wanted the server SKU.
Thus I fully switched to Windows Server to be able to check the same issues as the customers had, and since we only supported big iron UNIX during those years, I would anyway use telnet / X Windows to connect to those machines.
