Re: Resurrecting a Mega STE

One other silly thing to check.... make sure there isn't something amiss with the reset button. I've only seen it happen with a couple machines over the years, but it does happen.

Re: ST HDMI Out

You'll still need to make some sort of "frame start" signal out of Hsync and Vsync. If you don't, you'll be misaligned, and even if you do get aligned, it will drift. i was using Hsync to count lines, and just ran my output 2 scanlines behind the ST. (tho the overscan Hysnc oddities cause...

Re: ST HDMI Out

To be honest once the clock is locked, hsync doesn't matter. In fact I blew the hsync driver on my shifter by not noticing I'd shorted out the vsync and hsync lines, and I can still get a perfectly stable picture (although currently not correctly positioned based on v/hsync). You'll still need to m...

Re: ST HDMI Out

Sounds interesting. How are you handling 50/60 Hz and the various overscan tricks? I'm currently just doing 50hz at the moment and overscan tricks are fine as they just change when the display enable is active. This is where I found some issues. Some of the overscan tricks do "bad things' to H...

I'm intrigued by the "supershifter" idea, and if you have any specific thoughts on how it could be approached I'd be really interested. I thought about it before now, but given the time and cost it took to do the supervidel I didn't raise it. The reason I think porting SuperVidel isn't re...

Re: The future of TOS in the FireBee

The GEM, is already open by those who bought Digital Research, and that makes all the DOS parts of TOS, open as well. The only parts that aren't, are the Atari specific, and Falcon specific code. Atari is gone for good, Digital Research, as well. Which, as far as I know, more or less voids their ab...

Re: video shifter registers & palatte help

To get back on track a little, what mpu would you guys suggest to cope with a shifter that may well be double clocked in speed ? I didn't think at the time instructions take more than 1 cycle, so 40mhz is out. I'm sure I looked for something before and gave up (related to another project). Just ten...

Re: video shifter registers & palatte help

I still need to work out the speeds, though the shifter data only needs to bascially be stored in a ram location , couple of clock cycles, 40mhz, not much of a problem. ultraSatan is a much more complex thing, so yes it will need a faster MPU. Assuming a video speed of 16mhz for the data scream, an...

Hey exxos, I applaud your tinkering efforts, its good to poke around and experiment.

Sigh. No.
The .Net MicroFramework is open source.

You can port it to whatever you want. It is already running on sub 60 MHz ARM7 cores.
