Ihr fragt euch, ob es sich rentiert zu kommen und was auf einem VCFe wohl alles so los ist? Well … letztes Jahr war z. B. Dennis Kuschel mit seinen MyNOR und My4TH Computern da: https://www.youtube.com/shorts/jZ-7vy1XsPk #VCFe24.0 #VCFe #MyNOR #My4TH

@deadbeef Oh, that's a long story.

I read about #Forth in 1987 in a Commodore 64 magazine that included a homebrew Forth compiler written in BASIC.

It was slow and my 14 year old me was a little too young to understand the overall concept of the language. But I was fascinated by it and that stuck for decades (I even bought Leo Brodies book back then but never got beyond the first five chapters).

Fast-forward to 2022: after having fallen in love with the #rc2014 homebrew kit and having built several other #8bit replica systems since then, I learned about the #Mynor #My4th homebrew kit. It's a cpu-less 8 bit system (the CPU is made of discrete 74xx logic ICs) which features a Forth compiler instead of BASIC in its ROM.

I built it and then I *had* to get Forth into my brain to use it. And this time things fell into place. Having learned 8085 Assembler some 30 years ago may have helped.

I love Forth because it allows you to do rapid "function" prototyping interactively just like you would work with an interpreter language while it gives you the speed and low-level hardware access of assembler.

One of the rsults of my Forth efforts so far is the #TMSnake game for #rc2014 systems.

Just built a 4-port #I2C #bus #expander for the #Mynor #My4TH #ForthDeck so I can finally get rid of my current breadboard setup which has been sitting on my desk for far too long, causing even more of a mess. Turned out nice, I think ...

OK, I had a bit more problems as I expected. Because I used the precision sockets ROM and RAM are to thick. But the mounted #ForthDeck with it's #my4th inside fullfil my needs completely.

Shortly strait before home 😀​ The #ForthDeck can power itself and the #My4th, the keyboard caps are labeled. I cut up some pre-printed film and glued the cutouts to the caps. #Ender3 is currently trying to print a housing and I has to see what it turns out. Unfortunately one corner is lifting off the print bed.

Everytime a great miracle what @Mecrisp with his knowledge and experience is able to produce in some hours. He wrote a small disassembler to look up whats going on "insight" the #My4TH computer and it's dictionary.
Maybe it's an idea to send it to Dennis for publishing it on his website?

Congrats, really fast at #Reichelt. All chips are mounted and I am greeted by a "Welcome to My4TH". Really cute little SBC #WithoutAcpu and the basic commands are certainly included in #Forth2012. Even some I2C examples can be found here http://mynor.org/my4th.
There are still 3 purple boards left, it makes sense to order from Germany: https://www.ebay.de/itm/195778146717
