I have in my possession a 1994 vintage, Morgan Generic-badged, IBM Blue
Lightning 486DX2/66.  I plan, if possible, to add a network card and use
it as a Linux server/router/etc. and would be interested if anyone here
is familiar with these machines and can warn of any potential problems
or eccentricity or can point me at a good online source of this sort of
information.

It has 4x72 pin SIMM sockets, currently populated with 2x4MB SIMMS.  I
have a spare 4MB SIMM from a more conventional 486DX4/100 motherboard
(which won't fit the IBM case) that I could add to the existing 2 if a)
it is compatible and b) these SIMMS can be added singly, rather than in
pairs.  If I don't get any info on this I plan to just plug the extra
SIMM in and see what happens.  Am I likely to cause any damage by doing
this?
