a500 Video hybrid mod

Resurrecting the old topic - are these still available?

Also interested if there are any left. Need two.

I would be interested in one of these as well but I think they aren't available anymore.
However I have one rev.1 but the video-hibrid on the A500+ that I should replace is rev.3
Does someone know the differences between the two revisions?
Thanks.

I'm thinking of making an RGB-only board (and share the PCB design), would there be any interest in that? I could make space for optional sync/composite on the back or something but I don't need those signals myself. Schematics are certainly simple enough to fit larger 1206 SMD sizes with half of it cut off...

Hey mate are you still doing these kits? Im interested in some build it yourself ones.. im not new to soldering but its been a few years i just purchased a gba1000 rev 4 board and before i start i need something to practice on i have a 500 so im thinking this might be a good place to start.

Kipper2k:

Do you have a video hybrid chip for the A500/2000 for sale? I have a 500 that needs one.

The top left large cap gets really hot and the RGB port does not work, and the composite b&w output works but is dim.

You can build your own replacement better than Commodore - use 74AC245 as buffer and R-2R ladder DAC and http://www.st.com/content/st_com/en/...rs/tsh343.html as analog buffer - should be faster and more accurate (higher linearity) than original one.

+1 from me - have same impression about a1k.org - most unfriendly Amiga community.

Was it the vidiot -01 -> -03 replacement or the recap which cured the floppy access screen blinking problem?

Does anybody know if the built versions are still available? I would rather not attempt to solder all those tiny resistors!
