coco2, 26-3026 (socketed chips, melted kbd), 64k ram.

I recently bought an MC68B09E from Jameco, but when I swapped it in all I
got was interesting colors and patterns, no sign on.  I understood (perhaps
wrongly?) this was a drop-in upgrade that would allow stable operation at
1.7MHz.  I noticed some list discussion about Jameco having mislabeled
chips,  any way to rule this in/out by inspection?

Comments and advice?

Thanks,
Darryl
