Squeezing @BrunoLevy01’s RISC-V core onto an Icestick #FPGA is a lesson in “you really can do a lot with just a little”. So many lessons to be learned. At 50Mhz Pi and Mandelbrot work really well. I’ll leave the Icestick permanently hung off of this Raspberry Pi from now on. and the obligatory LED Matrix
There’s an add on to the romulator that uses an ESP32 to get rid of the need for a Raspberry Pi to flash it. But it does result in a strange tower of instability. I think I’m gonna just add a JTAG cable between them and lay it in the case out of the way. #commodore
Getting back to the 6560/1 drop in replacement project. Ended up just using a foam board to lightly double side tape everything on. This allows me to move the whole thing when I need the desk space for something else. Need to connect all the wires now #vicsrevenge #commodore
Put @adumont’s custom bios and 6502 Forth implementation on my CERBERUS 2080. I guess I’ll have to actually learn Forth now :) Happy Friday!
Happened to open Hacker News this morning and noticed someone submitted my article and I’m number 3 this morning. Since this internet is only for complaining these days, I think I will NOT read the comments.
Had this DIP-40 to IDC socket cable custom made and it looks fantastic. At least one part of the project will be neat and tidy #commodore #vicsrevenge
Broke out the Cerberus 2080 this morning to test out an idea on a 6502 at a fast clock speed. 8Mhz should do.
Ended up springing for the most up to date version of this book because… RISC-V. Lots and lots to study in here. #fpga #riscv
