Hi. I am new to this forum. :D
I recently found an Osborne 1 at my work, and I have been working to bring it fully back to life. Tezza has helped me a lot already. The good news is that it is in physically good nick, boots CP/M and can run SuperCalc and Wordstar (the apps I tried so far). Two of the paper filter capacitors in the power unit have exploded, but I have been replacing those, no problems.
The next bug I found is perhaps a but more tricky, and I thought it was a good time to introduce myself here and throw the problem out amongst the gurus.
First I found the Osborne will not format disks. Both drives A and B behave the same. I can hear the disk spinning but no head movement. The COPY program hangs as it begins to format the disk.
To see if it was a general problem with writing I tried saving a spreadsheet from SuperCalc onto the same SuperCalc floppy. I got the error "BDOS err on B: Bad Sector". I think this is just as likely to be a problem with the Osborne as with the disk.
Any tips on the best way to begin debugging this issue?
