Restoring C8PDF
Posted: Fri Jul 07, 2017 3:14 am
I’ve had success getting a C8PDF back to life. Involved replacing a bunch of bad 2114’s and modifying traces to allow use of 5.25 instead of 8 diskettes (I don’t have an 8” drive). I’m now am able to boot into 65D V3.3. I have three\four immediate questions:
1. I don’t have a disk 5 with the basic copier utility. Is there a single-disk copier utility embedded in the OS that I can call from the kernel?
2. I’m getting occasional flaky action from the keyboard. Of course some key bounce but the issue I’m seeing more of is random, inconsistent generation of characters with a key press. Also, occasionally it seems that the keyboard temporarily freezes but comes back to life without the need for a reboot. I’m guessing this might indicate noise over signal somewhere. Any thoughts on places to start with diagnosis of this? And any reason I should not use an electronic contact-cleaner to clean up the keyboard contacts?
3. Sometimes the machine will not permit disk boot until I first warm restart, enter the monitor, then warm restart and press D. Why??
Thanks for any guidance
