One of the minor hurdles that I have to deal with is how to connect the output from the amiga video, which is 5v to the FPGA at 3.3v. I was originally going to do a custom circuit board but that has turned into a pain...

I’ve been more active on the project than the posts have illustrated. I’ve been working on a few different things : Been trying different PLL solutions, examining how Paula does it, and actually analyzing my...
on floppy adpll, this time, my solution
This isn’t by any stretch finished, but it does do what I’ve expected it to do. It responds both to differences in phase (counter is set to 0), and differences in frequency (period is adjusted in the...
motor speed variation tests
I collected roughly 1,000 index pulses from the Sony MPF920-E with one common floppy inserted. The motor speed variation was very very small. I am impressed as to the accuracy. Across 967 index pulses, all were within...

FPGA implementation of AFP demo
more real world tests
So tonight, I put my new FPGA implementation of the amiga floppy project to good use. I read some more of my collection of amiga floppies. GREAT NEWS. It’s working like a champ. As a matter of fact, I selected...
