  • Instructions     from Nomad
  • There are three kinds of processors that are compatible with the Nomad board, all of which are slightly different: The 68000 is the "classic" 68000 processor.  This processor draws more power than the 68HC000, and cannot be clocked as fast. ...

  • Exception Handlers
  • Log     from 68008 Calculator
  • I have implemented a very simple exception handler so that I can figure out what is causing the machine to fault. The exception handler is telling me that the issue is an invalid instruction. It turns out, I forgot to add -march=68000 -mcpu=68000 to...

  • STEbus 68000
  • Details     from STEbus 68000
  • From the ASCII text in the firmware, I believe this board came from an OS-9/68000 system made by VG Elemental, and a product called the PlasmaQuad. https://www.precisionglassblowing.com/product/vg-plasmaquad-2/VG Elemental seem to have been...

  • Retro 68000 CPU in an FPGA
  • Details     from Retro 68000 CPU in an FPGA
  • I've wanted to build a 68000 system for a long time. I built some commercial systems back in the 1980's based on the 68000 and really like the CPU.  There's a few 68000 builds on YouTube. The best documented 68000 build is Jeff Tranter's build...

  • This project is a homebrew computer based on the Motorola 68000 CPU. Design includes four megabytes of RAM, 128kB of ROM, Something for video, two serial ports at 9600 baud, and eventually networking and a hard disk.The purpose of this computer is two-fold:...

  • Up and Running
  • Log     from Retro 68000 CPU in an FPGA
  • After a few days of messing around with the FPGA top entity, I got it running and was rewarded with the TS2BUG prompt on the VDU. Lesson LearnedFPGA implementations of CPUs rarely match the pins of  the original part. They are typically poorly documented...

  • Finished FPU
  • Log     from Merlin
  • Finally got a stable working FPU which is compatible with printf. I was surprised by the amount of maths used to print a floating point number. I have new wrapper functions now which replace the 68000 FP emulation code provided with the gcc compiler....

  • MCL68+ Motorola 68000 Emulator
  • Details     from MCL68+ Motorola 68000 Emulator
  • The MCL68+ is a Motorola 68000 drop-in replacement emulator. It uses the Teensy 4.1 to emulate both the microprocessor and the local bus interface at full speed. It is the most ambitious drop-in emulator I have designed to date, and I am pleased with...
