Re: Oricutron macOS 10.14: Unable to open roms

If you didn't already take a look in the Oricutron's Makefile at 'package-osx:' receipt. There are some tricks with symlinks.

Maybe it's just typo, but normally it should be center POSITIVE jack. ...With the IDC disconnected and Powered from the Cumana the Orics will not boot. This means Orics mainboard are absolutely wit...

Re: Composite video mod?

and got the ".tap -> .wav -> Oric's tape input" path to work. Both using smartphone or PC to play the .wav's. You can try TapOric to playback TAPs directly from smartphone. Any feedback is welcome (i.e phone model used, stability...), I'm planing new release with faster speeds included soon.

Re: Composite video mod?

... good converter from the 74LS365, RGB+Sync Outputs to Composite video, ignoring the UHF part ? @Voyageur : Take look here for good RGB - Composite/S-Video converter .

Re: Oric ROM wanted

Differences are only: - not fixed CLOAD/CSAVE routines - Cyrillic chars in place of small Latin letters - k...

Big thanks from me too!
I've made new full check-out of the svn and compared the files and their content with last before the failure and everything is the same and OK!
