Down at the left bottom of the forum's thread pages (e.g. Hex Eng) there are three pull down menus. One is 'Sort Order', one is 'Sorted By', and the third is 'From The'. Lastly, there is a button 'Show Threads'.

The default for 'From The' is 'Last Month'. Use the pull down to change that to 'Beginning', then press the 'Show Threads' button. You should see something like 60 pages of Hex threads listed (at least for me, as I see about 20 threads per page, that may be possibly configurable), or nearly 1200 threads.

Thanks rj, that solved it. Spent three hours reading starting from the last page last night.
