Magazine Scans
Over the years, I've tried to contribute various publications to archive.org where I can. For my own reference, I've collected links to the various items here.

Palmtop
While I cannot take the credit for digitising these, the Internet Archive has a number of issues of Palmtop magazine. As it can be difficult to get an overview of what's available there, I've collected links to those issues I've been able to find.
T3
Growing up in the UK in the 90s with limited access to the Internet, T3 magazine was the first (and invariably only) way I encountered new gadgets.
Since Future Publishing doesn't host old content and archive.org (specifically The Magazine Rack) has only a couple of issues, I picked up a few copies on eBay with a view to contributing scans. Unfortunately I received a DMCA takedown request soon after uploading them, so here are just the covers for reference. Hopefully I can find a better way to make them available in the future.
