Yeah I also have 10BaseT transceivers (if needed), CAT6/connectors/crimp tool/test tool and even a pair of 24 port switches.
But I don't want UTP cables all over the place. The great thing with 10Base2 is you have just a single cable running the outside of the room.
Currently got 5 machines on the network, but need to connect another 4 or maybe 5 to get the room done.
Also grabbing a 10BaseT switch with a 10Base2 uplink - handy for laptops etc to quickly plug in to.
(Not hardware related, but kind of shows what I've been up to!)
Protip - avoid IRQ 5 and the address 320H on an XT - took me longer than it should've to work out
