[comp.sys.atari.8bit] High-frequency hum when using Concurrent I/O

charles@c3pe.UUCP (Charles Green) (02/27/89)

Ever since I started using my terminal emulator, I have noticed a medium- to
high-pitched hum when it starts up concurrent I/O mode.  Unplugging my ICD
P:R: Connection makes the sound go away, which leads me to believe it is
being generated by the serial interface, and not by the 800XL CPU.

Has anyone else been bothered by this?  How about 830 owners?  Is there a fix?

Please Email replies and I'll summarize.

Thanks,		Charles Green		charles%c3pe@decuac.dec.COM
