Description

What I would like to see from Mark sometime in the future, is to integrate the Atari OS in the flash ram.
Dream for the day who I will push the power switch, and I will see the "Basic" blue screen, without the need of SD card.
A board with Atari SOUL!!!!

I'll start by a default one in block ram, (optionally overriden by sd card). Then later we can add support for the flash reading.

Thanks!

Also of course nice and fast vs uncached sdram...

sysinfo fp test from 6x->20x :-) I probably need a cache to get this closer to 30-40x, but that will take some work.

??? What you mean here?

I'm using block ram in the FPGA for the OS ROM and BASIC. It can be read in 2 cycles and written to in 1 cycle. SDRAM takes about 5-6 iirc. So in turbo mode, with no cpu cache, this makes a huge difference in speed.

Added basic support, see related issue.

I still plan to do the flash reading later.
