I'm interested in the same issue too - I've got a TRS80 Model 16B that was living in an unused bakehouse for a few years - I think it's a box of dust with some circuit boards in there somewhere :-) I heard a substance you can use that is non conductive and leaves a protective film on the board after - I think its CRC 626 or CRC 262 or similar - someone on the list might know a bit more. ++++++++++ Kevin Parker Web Services Manager WorkCover Corporation p: 08 8233 2548 m: 0418 806 166 e: kparker(a)workcover.com w: www.workcover.com ++++++++++ -----Original Message----- From: cctech-bounces(a)classiccmp.org [mailto:cctech-bounces@classiccmp.org] On Behalf Of Gavin Thomas Nicol Sent: Saturday, 1 January 2005 3:37 AM To: General Discussion: On-Topic and Off-Topic Posts Subject: Cleaning motherboards... Apart from dusting with compressed air and camel hair brushes, which removes the dust from circuit boards, are there any recommendations for cleaning the general grimy file from motherboards? ************************************************************************ This e-mail is intended for the use of the addressee only.
