So for my fixed point number format for my 3D project, I’ve come up with a few possibilities : I think a 16.16 number format might work for me. This means I’ll represent the whole portion via one 68k word...
3D Wireframe Rotation dreams…
So I’d really like to be able to rotate 3D objects using this computer. There’s some problems though that make it a little harder than normal. The 68000 doesn’t have any integrated Floating Point...
Adding Yamaha YM2612 support has begun
So after much time talking about it, and doing research, I’ve finally got around to spending some time on adding Yamaha YM2612 support to the badge computer. I created a small verilog driver that read the...
New Indiegogo for Amiga 500 cases
I think everyone could use a brand new sparkly case for their Amiga 500’s. I saw the campaign for the A1200’s last year, and I was jealous. Where is the A500 stuff? Also the keycaps. Your keys are going to...

Updated hope badge computer
Here’s the current image for the Hope Badge Computer, which I really think needs a new name. It’s not quite a badge, although the intention is for it to be portable. Last night, I partially integrated the...
