Gavinmc42: I bought a Mac II in 1987 specifically to develop the first of my Scheme implementations, simply because it was the only personal computer available that had a big enough flat memory-address space for a decent main memory --- the segment registers and 256 Kbyte segments on the Intel proce...

Gavinmc42: I wrote a lot of Scheme tutorials that accompany Wraith Scheme. They are not on line on my web site, but there is a way to get at them if you don't have a Macintosh handy: Go to my web site, www.jayreynoldsfreeman.com. Mouse the "Software" tab at the top, then "WraithScheme...

Gavinmc42: I will be most curious about whether and how well Weasel Scheme works on other versions of the Pi hardware than the Raspberry Pi 400: Please do post results with plenty of details. I have been using a 40-pin ribbon cable and a breadboard for simple tests of the Pi 400 I/O stuff. Stick in ...

Gavinmc42: I will see about putting I2c in Weasel Scheme as soon as I figure it out myself -- I have not used it. I have a good reference book that will probably allow me to see about writing a driver for the Pi I2c and putting it in Weasel Scheme, and I think I have sufficient hardware on hand to t...

Hi Gavinmc42, Scheme is a small and powerful Lisp. If you want things to do or ways to learn it, I would suggest some of the books in the "Scheme References", "Lisp References" and "Other References" sections of the Wraith Scheme Help File (which provides documentation ...

I recently posted that I was developing a version of the Scheme programming language to run on the Raspberry Pi 400. I have now released that program -- Weasel Scheme -- and have put it up on my web site where you may download it. The URL is http://www.jayreynoldsfreeman.com/My/Weasel_Scheme.html. B...

I have a fairly complete freeware implementation of the "R5" version of the Scheme programming language, that runs on the Raspberry Pi 400 and quite likely on other 64-bit versions of the Pi. The spinoff project is called "Weasel Scheme", and it runs in a terminal shell. If anyon...
