The granddaddy of all FORTH related books, "Threaded Interpretive Languages, Their Design and Implementation" can also be found online. Not really a FORTH tutorial, the book describes in detail how a TIL works using Z80 code to build the threaded variations.

Note that this link is broken when used because the "1981" at the end gets translated to an escape sequence - click on it then edit the resulting URL to remove the junk at the end and replace with "1981" as required. You can also copy and paste the link to a new page and edit accordingly.

I regretfully have to join the "chip shortage club" with Tony (teenix) as the PIC processor used by the MultiMod is not available until May of next year. Assuming they don't sell out immediately! There are some chips offered on The Bay for $8 to $15 each, but who knows what you're buying AND shipping is $10 or more.
