Re: RGB to HDMI does this work with a ST

All those cheap HDMI converters; I've bought a ton of them and none have done 50 Hz motion. They have either dropped every second field of the PAL signal or added a de-interlace that merges fields. Either way, the end result is 25 Hz motion. Not good enough. Excuse my lack of proper eyesight :) - s...

Re: RGB to HDMI does this work with a ST

I compared the different models, and shared my findings to the community: https://www.youtube.com/watch?v=c25dlHFW584 Hey, this is really a neat idea! Naturally, these converters don't care about Hz/V frequencies, only about colour signals. I'm wondering how come nobody has thought about this befor...

Thanks for looking, Arne. In the end I have agreed to pay $25 + postage fees for the disk. I only hope that it's a working unit as the seller couldn't guarantee that.

Re: Sparrow inspection

By the way, here is the one page of an Atari Sparrow schematic that I could recover. It seems to be a very early revision, still with separate VGA and RGB connectors, so it most likely doesn't match mikro's board. At first glance it looks like a STE with chips names GSTMCU and GSTSHIFTER. But at se...

Re: Sparrow inspection

Small update: I was able to verify that the ROMs which are given by Steve from Wizztronics along with his Sparrow boards are the same as mine. So you're not missing anything, the version from 29 Feb 1992 should work everywhere.

Re: Sparrow inspection

Probably you all already know, but there is an Atari spec for the Sparrow incl. registers. Unfortunately, formatting has been lost: https://forum.atari-home.de/index.php?action=dlattach;topic=13380.0;attach=12961 I wonder if mikros dump confirms the registers shown there.

I doubt that. TOS ROMs had been updated regularly, can't imagine somebody doing translations for it. Also, all Sparrows I have ever seen had only US keyboard layout.

Perhaps you have noticed on FB that I could finally take a look on my Sparrow. I'll post all findings to this thread. I'll post some motherboard photos / findings later as I want to do a few tests yet. Basically, the whole machine feels very STE like. Mine has a SR-298 PSU (I guess it's an iteration...

Re: CosmosEx on 520 ST (no floppy)

I'm planning to go the same way but my idea was to do it more "native". I.e. put the unit into an old SF314 case and connect it via both floppy and ACSI cables (along with the power cable). This solution also requires a simple cable from the CE to the IKBD connector but still much better (...

Actually the fact you made it crash during FreeMiNT is much better than with NVDI. Because, you know, FreeMiNT is open source. So you can pinpoint the exact cause.
