Well, I have some spare 8050s & an 8050 all in various stages of 
disintegration. I'll try some chip-swaps tonight, to see if I can get 
anything working.

Indeed. Does "Zero Page" mean the drive is unable to retrieve data from the 
chip, or it's all coming back as zeros, or something else entirely, do you

As far as I'm aware, the 8250LP is basically the same as the 8250, only 
with 1/2-height drives and in an aerodynamic box. I could, quite possibly 
however, be mistaken. They look nice, especially compared to the 
full-height units, but they're still spectacularly heavy...

Cheers, Ade.
