Re: Clock Signal — an Oric emulator for macOS and Linux

Well done and great progress! About the BD500 support I found that clksignal fails to boot (and displays color garbage on screen) when you force to use Oric-1 v.1.0 ROM. No problem with Atmos 1.1b ROM which is automagically selected by more 'votes' in the StaticAnalyser.cpp. Here is a quick fix: Ins...

The name ends with _dsk It's not .dsk.
Or the full name here is: B7en-1_3_dsk.HFE and the extension .HFE is hidden by FlashFloppy firmware.

Re: Is BD-DOS lost to time?

So I would assume that the 34-way cable is a standard Shugart floppy interface. +1! The list of things... It was not meant to be offensive in anyway! With full respect I'm sorry for the unsuccessful joke. Actually I was very excited to share the "discovery" about $31A. ;) Is there a side toggle? Is...

Here is how the "Hybrid" cable looks: bd500.png Found in "Computer Answers" 1984/05 pages 19&20. Recently I found somewhere better picture but unfortunately I forgot to save it and now I can't track it again. But anyway I doubt that there is a hope to have the schematics :(. Even if we have the hard...

Re: Clock Signal — an Oric emulator for macOS and Linux

Here one more tip for SDL/Linux users - starting clksignal with: $ MESA_GL_VERSION_OVERRIDE=4.5 LIBGL_ALWAYS_SOFTWARE=1 ./clksignal <path_to_media_file> should help on older machines which drivers doesn't support latest versions of OpenGL. You can try how it runs with only first, only second or both...

Re: Jasmin time

Was that tested with only one Oric and one Microdisc or Jasmin unit? I'm using 4 Orics in the test and only 1 Jasmin drive. There is no difference when changing the Oric and I consider this as stable basis to search the issues in the Jasmin only. Else the quartz looks old but nice: quartz-8Mhz.jpg ...

Re: Clock Signal — an Oric emulator for macOS and Linux

Thanks for your effort! One more thing but only related to myself: RTFM - there is difference between this two calls: ./clksignal --quickload --output=composite test.dsk and ./clksignal test.dsk --quickload --output=composite Only the second works! EDIT again : More tests and it works fine in RGB wi...

Re: Jasmin time

Have you tested the clock signal on the Jasmin? The clock is 8MHz with acceptable tolerance, not very good looking but here the oscilloscope is to be blamed: 8mhz.png More important there is definitely a drift between 8MHz clock and the 1MHz F2 signal i.e. the phase difference is not constant.
