Forth on 71B Message #1 Posted by Xerxes on 8 May 2008, 9:53 a.m. What are the differences between the Forth versions of the Forth/Assembler ROM and the 41 Translator ROM? What was the reason for having two different implementations of Forth? Which version is preferd by Forth programmers?

Re: Forth on 71B Message #2 Posted by Egan Ford on 8 May 2008, 11:21 a.m., in response to message #1 by Xerxes AFAIK they are mostly the same except that the 41 Translator ROM has a few extra functions (e.g. CLOCK) I prefer the 41 Translator ROM because I use CLOCK to time my programs and I have the 41 Translator ROM in my 71B. Both can run in EMU71. I'd suggest that you get them and the docs if you really want a comprehensive list of differences.

Re: Forth on 71B Message #4 Posted by Raymond Del Tondo on 8 May 2008, 4:56 p.m., in response to message #3 by John Pierce Back then in the eighties when the HP-71B was hot, someone from Northern Germany also made an assembler in BASIC, without the need for a FORTH/Assembler ROM. AFAIK the JPCRom also includes an assembler.
