At least the core stack is there.  That and certain components of the
G-series modules are somewhat difficult to obtain as spares.

It looked interesting to me just because I have a pile of M-series
logic and a spare PSU from a broken and gutted -8/L I got when I was
16 (it was missing the plexi, the core stack, the front steel
backplane support member was detached from one side of the chassis,
and a few of the backplane pins were broken off due to rough handling
before I got it).  I probably have everything on hand (including M220
modules) to get the one in the auction working, but I'd have to dig
deep into my pile of M-series modules awaiting diagnosis and repair
(including those M220 modules).  Given what I've seen over the years
on these particular machines, testing for defective 7440s and 7474s
will identify 80% or more of the bad components.

I'm mildly interested in the one in the auction, but not so interested
as to run the price sky-high.
