Has anyone modified Warren's VTServer to ignore errors (or at least keep
trying upon encountering them)?
I'm trying to image some rl02s I found and am getting flack on some tracks,
killing the whole recovery process.

Hi - I finished the scan of the MPI 91/92. I did it at Kinkos and it cost
me $54, and wow that's expensive. I should have asked before I dropped off
the manual. I kind of assumed it'd be more like $20. I don't have an easy
way to scan a plastic spiral-bound two sided document with pull out

Are you confusing this with the serial CRU I/O scheme TI computers used?
