Unhappy CD723 Hack, did someone download it?

I was very interested when I read that it is possible to turn off oversampling in the Philips CD-723 and the likes, but now that I have a CD-723 ready for surgery... I can't find the source code to program the hacker!

It was discussed here Thread on 723-Hacker , but the site is now unavailable

Did someone save it? I'd really appreciate.....

Cheers

Andrea

Thank you very much, now I need to find a Atmel AT90S1200 and a suitable programmer

Cheers

Andrea

PS Did you try it out?

I contacted Robinet on this a week ago, he's gonna try to get the site up again.

Btw, if you send him a controller, he'll send it back to you programmed.

Actually he is the first person I contacted (trough the mail service of the forum) but didn't get a reply, so I asked here.

As for programming, if someone already has a excess Atmel chip and is willing to program it for me it would be really great (of course he'll be rewarded for that ) , otherwise I'll have to go and search for a chip and dig up my old Willeprom programmer (DIYed) that IIRC can program these chips.

Cheers

Andrea

Default Great news!

A few days after my las post on this thread Robinet replied me and sent me the file with all the info needed.

Today I got my Atmel chips and, after finding that at my workplace we have a programmer that supports it.. I quickly assembled the board and tried it: success!! It worked a charm.

Here is a piccy of the hacker in action:

Here is the original waveform 4xfs (sorry for the bad pic but also the waveform doesn't look that good )

Next step is to install Thorsten's tube stage for TDA1545A (with his non-OS modifications)
