The HP t5325 thin clients run Linux and some custom software to fire off terminal sessions. Anyway they use an ARM processor and some strange Volari IC I’ve not seen before.
The ARM process is a Marvell IC labeled: 88F6-BIA2 N3N921041 1102 A1E TW 89F6261-A1
The XGI Volari Z11 is odd, will have to try and find more information on this.. labelled WC0010 W1104CB. Looks like it’s a graphics processor of some kind.
