Re: STFM to DVI/HDMI project

Would be possible to add one feature - scanline mode? Yep, easy. I've got that planned. Do you think just darkening every second line is the best approach? Possibly a bit of overbleed from bright pixels into the adjacent ones would also look good? I actually don't own a CRT to study how it really l...

actually I have no your converter yet, but I have connected ST to LCD TV via VGA cable (my TV accepts ST-LOW via VGA), and that screen resolution is a bit blocky.

Re: Advertising Atari with sexy girls.

Amiga wasn't really very good at midi. I'm getting one up and running now, but it seems to have an interesting problem where the serial port buffer is only one byte long. So if you miss your window of time to grab that byte another MIDI message will come along and happily blast away your buffer. An...

Re: The Falcon's confusing history

Keep in mind that ALL of the ST/STE/TT/Falcon machines had basically the same system architecture as the original 520ST that's not exactly true. ST/STE/TT share the same concept of sharing bus ram (ST-RAM) - even cycles are assigned to the CPU, and odd cycles to the Shifter. Therefore regardless of...

there is workaround for that, use MMU and mark a memory area with Interrupt service code as uncacheable.

Re: Maxymizer and SPDIF on 030

Maybe I'm wrong but it could be something wrong with Matrix chip settings. That chip has some inputs (YM, ADC, SDMA, DSP) and outputs (DAC, SDMA, DSP) and you can reroute needed input signals to needed output There were an application where you could define that Matrix routing. ---EDIT--- http://www...

Re: The SECRET VIDEO MODE in an ST: 400 lines in COLOR (and with 72 Hz)!

what about EmuTOS 1280x400 interlace Interlace on the ST means two different framebuffers for the odd and even frames, I'm quite sure that EmuTOS' VDI isn't up to that without significant changes. yep, it would be a challenge in case of ST.

Unfortunately, this means that unless there is way to force the GSTMCU to always generate /BLANK or to force the Shifter to ignore it -- and I don't think there is --, this 400 lines color mode will not display anything in an STE without HW modification. :( until somebody breaks it, as it was done ...

This is fantastic. I've spent a lot of hours trying to achieve something like this. How are you running GLUE in one mode (high) and Shifter in another (color)? I can indeed have Glue and Shifter in permanent disagreement about what the video mode is. The key to this is that Shifter doesn't have a a...
