Enjoy Amiga with real DIP64 MC68000!

Minimig v1.91
B52/ROAM

This is very significant release – hardware and software wise. 

Changes to the PCB:
1. New PCB, 6-layers ENIG gold plated. 
2. Super coupling design – SIGPwr-GND SIGPwr-GND SIGPwr-GND. 
2.1 Significant improvement in track routing.
3. Lvl shifting – super fast SN74CBTD
4. Finally +5V voltage regulation including using DC-DC
5. For power supply Minimig can support anything from +5V to +12V
6. Resettable fuse added
7. Schottky diode added – SBRT 
8. ESD protection added to joystick ports
9. LEDs for power status +2.5V, +1.25V, +3.3V, +5V
10. New solid caps
11. Now Minimig comes with +12V 4A supply so you can run your favourite 030 accelerator. 

What can board do?
1. Support for 58MHz-60Mhz MC68SEC000
1.1 Support for 32MHz MC68HC000
2. Support for TerribleFire card, 030 tested – Only 50MHz 68030
3. Support for other random accelerator cards. 020 card tested.  
4. Full support for PiStorm including – caching kick.rom due to the fact that BOOTROM is gone!
5. Improved FastSPI. 

This release includes new Amiga ECS/OCS FPGA core. 

I am happy to say that new MIA chip is included in the latest version. MIA chip is responsible for BOOTROM replacement. 

Removing BootRom was very important for accelerator compatibility and PiStorm. 

Please keep in mind that many accelerator boards will work with Minimig v1.9 but not all. So far I tested PiStorm, TF030@50MHz amd 68EC020-TK.

Tall – HDMI Acrylic case is included with the purchase.

What’s Included

Minimig 1.9 board with SD card (16GB) containing Minimig FPGA core, MC68SEC000 @ 58-60MHz, Universal power supply +12V 4A
