Icaros Desktop 2.2 and Classic Amiga upgrades

My apologies for the lack of blog posts recently. This has been due to a long personal illness, a death in the family involving travelling to Japan and also work being incredibly busy. Sorry for this but it was beyond my control!

But despite this I have not been idle with my Amigas and indeed have been busy doing work on Icaros Desktop 2.2 upgrade on my Acer AspireOne, Classic Amiga upgrades for my A1200, 2000 and 4000D, and even doing more work on my Amiga 4000T too!

Frame Buffer and Text Generation now working…

Now that I have the 4MB SRAM board installed, I now have a frame buffer that can keep up with the video bandwidth rate.

The resolution and color depth is currently 800 x 480 x 12-bit. The computing shield I’m using only supports 12-bits, but my LCD can do 24-bit.

Essentially how my frame buffer works is that you write the 12-bit color value into an address in memory that corresponds to a location on the screen.

See Framebuffer at Wikipedia.
