Have seen several mentions of porting forth or forth-like systems in recent messages. I would like to port forth to a somewhat old machine for which I have seen no forth support. I would appreciate information on books and articles which would assist in this and a suggestion for an existing forth system for which the source is available (especially machine readable but I can live with a listing). The target machine is 16 bit words with 8 registers including 3 index, 1 return address, 1 top-of-stack/base-address, and 3 other accumulators. (I provide this for maximizing the closeness of architecture between the existing and target implementation). Thanks for any help. Jeff Sicherman jajz801@calstate.bitnet

Why not find a FIG chapter and get their implementation? What you've got sounds like a superset of the 8086, so the version for that should be a reasonable start; maybe take a side look at the 68000 one too. There's a book by Loeliger, "Threaded Interpretive Languages" (McGraw-Hill) that gives a detailed description of a Z80 implementation of something vaguely FORTHish. best wishes - jack -- Jack Campin * Computing Science Department, Glasgow University, 17 Lilybank Gardens, Glasgow G12 8QQ, SCOTLAND. 041 339 8855 x6045 wk 041 556 1878 ho INTERNET: jack%cs.glasgow.ac.uk@nsfnet-relay.ac.uk USENET: jack@glasgow.uucp JANET: jack@uk.ac.glasgow.cs PLINGnet: ...mcvax!ukc!cs.glasgow.ac.uk!jack
