their pilot runs of parts (usually distributed as
samples) with an
'XC' prefix! I once had an XC6800 in one of my ss-50's! It was in
what I can only describe as a 'clay' (okay, some wierd ceramic
material) package. Never saw anything like it before or since.
Motorola has always been a bit loose about letting "XC" labeled parts go
out to production (I have seen Macs with XC68020s, and some production
XC88000 stuff).
I too have some XC labeled 6800 stuff, and yes, it is in weird packages -
it almost looks like the ceramic did not form correctly!
I think Motorola has another prefix for things that stay in the labs (like
preproduction prototypes), but I can not remember what it is.
