Carsten & List, Back in 1984 I bought a ROM of David Husband's ZX-Forth for my ZX81 - published as Skywave FORTH http://www.worldofspectrum.org/infoseekid.cgi?id=1000370 The source is here from contributor "Moggy"...

IMHO 7 primitives is a bit too few - and this is confirmed in the 708 times slower performance. Both C.H. Ting and C.H. Moore settled on "about" 32 primitives...

You could look at sectorForth, implemented in under 512 bytes, to fit in the boot sector, in x86 assembly language https://github.com/cesarblum/sectorforth It was inspired by Bernd Paysan's post from 1996,...

Mitch, This summer I acquired a Mac Classic 2 - circa 1990. I have half a plan to turn it into a Forth workstation - the ultimate retro machine. The...

Sometimes described as a list processor - as the sort of embedded tasks we do today are well suited to being defined as lists of actions. For example 3D printing,...

Hi All, I have had a preliminary investigation into the first FORTH running on the IBM 1130. This is detective work on a processor that was "born" the same year...

Lars, You can follow the progress of the IBM 1130 restoration and early Forth here on Carl Claunch's blog. https://rescue1130.blogspot.co.uk/2018/03/original-forth-from-ibm-1130-under.html On 24 March 2018 at 15:58, Lars Brinkhoff wrote: >...

Hi All, Today I decided to focus on the first 40 lines or so of the Forth listing. I have attached a text listing. These lines define the assembler and...

Lars, Just to understand the assembler and the asm needed for the stack operations is a major breakthrough in understanding IBM 1130 Forth. I am now starting to unravel just...

Brad, List, The MSP430 is a great little microcontroller, easy to learn ISA, and a good fit to the requirements of Forth - being 16-bit, a good set of registers...
