   I am having some problems with my 130XE after doing some hardware hacking
on it. I damaged a line or two removing a broken socket but managed to trace
them and rewire them. Now I am having a problem with my disk drive. It appears
that the data coming from the drive is getting scrambled. Disk directories
list some entries properly, but others have messed up characters. I think some
of them have bit 2 (the "fours" bit) stuck low. I don't have the schematics
of the 130XE, so I can't even tell which chip has the problem. Data read from
files was ok to start with, but now seems pretty munged. Fortunately, the
problem does not seem to bother the ECI (parallel port), so my MIO still works.
Any tips on what to look for would be appreciated. In case it might help, the
hardware mod I did was the installation of the Turbo-816 and Turbo-OS, which
seem to be working perfectly.
