6502.org has a long (but not quite complete) run of Micro magazines scanned and online as PDF files at:http://6502.org/documents/publications/micro/
This classic magazine has tons of features on the Kim-1, PET, VIC-20, and Commodore 64, as well as other 6502 based machines. I think they went out of business right before the C128 was introduced, but there's still lots of interest to C128 owners there.
As a testament to this magazine's staying power, there were recently three 8 to 9 issue bundles of old Micro mags on eBay. Last time I checked, the bid for each bundle was over $50. Try to get that much for your old INFOs!
