Amiga: Vampire II videos from Flype44

Hi guys,

I never get tired of seeing the Vampire II in action. A YouTuber called Flype44 has now uploaded several videos showing his Vampire-powered Amiga 600 burning rubber. Please have a look at the videos below and enjoy!

First up is two videos showing 194x, an SDL-game on M68K with RTG driver + Sound.

Reverse engineering the LCD interface

So I was having trouble getting the LCD working initially, so I ended up probing a working HDMI to LCD converter board sold by adafruit. You see, this board was driving my LCD just fine, but my FPGA couldn’t do diddly. So I wanted to see what I was missing.

This proved more difficult because of these 40-pin FPC connectors. Not sure what the pitch is, but it’s really freakin’ close together.

With a lighted magnifier (3x diopter?), and sharp o’scope probe, I was able to isolate individual pins on the 40-pin, long enough to hit the stop button on the scope.

Working on the User Flash Memory

So the Altera Max 10 FPGA we’re using has 256kbits of User Flash Memory. This is non-volatile memory that is built into the actual FPGA itself. This means you don’t need any external memory to get the FPGA to boot itself.
