Ancient non-PC computers (Ross on Wye, HR9)

I'm a collector of ancient computers. I'm always on the lookout for more to add to my collection. However my tastes are pretty specific. I am not looking for PC-style computers (windows, mac, etc). I'm on the lookout for older industrial computers. The big old systems that businesses used to use in the 60s to 90s. Things like SUN computers, Digital VAX, PDP, etc computers. SGI computers. Basically things like UNIX workstations, and very old servers. The kind that used to have dumb terminals on them. Speaking of dumb terminals, I'm always looking for those too, though they seem to be very hard to find now.

Now I'm not expecting any of you to have anything sat tucked away in your garage gathering dust, but maybe you know someone that knows someone that might have something. Maybe you work with someone. Maybe you sing in a choir with someone. Maybe you play pickleball with someone. If you do I'd love them to get in touch.
