Re: What video display do you use?

The trick is to look for DVI transmitters rather than HDMI, there is still compatibility but the resolutions are 'limited' to 1080P. Look at the Ti TFP410 Can't see what difference that chip would make to directly using an FPGA. As soon as you make a device with HDMI output connector, it is no long...

Re: Status of QMON

Any update on the status of QMON? As to their websites, I can see neither Jochen Merz nor RWAP selling it.

Re: What video display do you use?

On the other hand, is there a 50Hz version of 1024x768 VESA? No, the nearest standardized refesh rates are 43 Hz interlaced and 60 Hz. HDMI - transmitter chips that do not have content protection (so no royalties) can still be found. I'm curious. Have not seen a way to legally get around paying the...

Re: What video display do you use?

I too have been toying with some ideas to get a 1024x768 XVGA (at 60Hz) image straight out of RAM, but with limited knowledge/capability around FPGA stuff, had been investigating the bus-snooping approach using a (fast) microcontroller and an SRAM shadowing approach. This is exactly the Q68 VGA out...

Would that converter use 68008 bus snooping or the RGB signals?

Re: Rs232 TcpIp Socket PPP

On which platform? Linux supports both SLIP and PPP, recent Windows only PPP. On the QL side, no TCP/IP stack has been released yet. I did, however, successfully use SLIP as part of my QLwIP project. SLIP is a nice simple protocol. Unfortunately the fact that Windows abandoned SLIP, restricts useabi...

Re: What video display do you use?

What tofro uses, and I also own, looks exactly like the SCART-HDMI converter in your link. But with my QLs, the picture only appears shortly from time to time. Even with identical SCART cable wiring. So I also had to resort to the GBS RGB-VGA converter. Not very sharp output, and it takes a minute t...

Re: QL Hard Disk 40MB from Miracle Systems

Could you please provide details on your HDMI upscaler? The output looks very sharp.
My SCART to HDMI converter does not work with the QL.
So I still use the large, heat-generating, uncased GBS-8220 which creates slightly blurred output.

Re: Using big ROMs on Q40

You only need one pullup and a switch between A17 and GND.
