Wherein Joey deVilla is selling a Symbolics XL1200. All the details are
in the link, but some overview: The machine has a hardware fault that
prevents it from fully booting, but it does display said diagnostic message.
The machine itself is in Toronto. I'm not sure if it's sold yet or not, as
the message was put up on Saturday (and I'm just noticing it now).
I'm not involved with this in any way, other than just passing on the
information. I've bought some books from him before (and he's got a ton of
books for sale as well) with no complaints.
-spc (He also goes into the story of why he's selling the unit, which
is amusing ... )
