Re: HELP with UniDisk 3.5'

[Paul G <gavp@gis.net>]

If the computer been in smoking conditions you might consider cleaning up all contacts on
motherboard and chips.  I got this Apple 2e once from a smoking user.  The unit was twice
as dark cause of  layer of tobacco slime.  When I tried to turn it on the display flickered
and displayed some I/O error messages.  I cleaned whole motherboard and removable chips and
it worked flawlessly after that .  Hope this helps.
