I have a slight problem which I hope someone can help me with.  The computer
science club here at Waterloo has a couple of HP9000 series computers with
what we think are 68000 processors.  The only trouble is, when we open them
up, the only thing that can be found that even vaugely resembles a 
microprocessor is a 10x10 PGA (number of centre pins removed: unknown) labeled
as follows:

(Motorola logo)
1820-3288
GN78427

According to all the data books I have looked in, this is either a 
68000, 68010, or 68012.  What we think we have is a 68000.  We want either
a 68010 or 68012.  I suppose that a quick software check should be able to 
tell the difference appart between the 10 an 00, but not the 10 and 12.
Besides... we'd like to know exactly what we have.

Can anyone help?

Thanks.
-Andrew.
