Music 4000

Is the Music 4000 keyboard matrix documented anywhere? There's plenty of info at https://www.retro-kit.co.uk/page.cfm/content/Hybrid-Music-4000-Keyboard/, but no matrix. I've emulated the keyboard but would like to understand the matrix ...

Re: MAME: Hybrid Music 5000

Have a look at Pi1MHz M5000. This does simplify the time slot method to significantly reduce process time.

Re: MAME: Hybrid Music 5000

Given we have original documentation like the schematic, and a RTL-level VHDL rendition, is it that important for the MAME implementation to illustrate the original pipeline as well? No, not that important. It's just that b-em did things when pc=0, 2, 5, 6, 7 which doesn't match the hardware, so wa...

Re: MAME: Hybrid Music 5000

Can you also explain what happens in the other time slots initiated by /S0, /S1, /S4, /S6, /S7. It's a pretty complex pipelined design, and I don't recall exactly how the pipeline was laid out. So I'd need to go back to the VHDL and work this out again: https://github.com/hoglet67/Music5000/blob/ma...

Thanks to both, am trying to absorb the info which is not easy in this heat! Stepping back, what's happening here overall: - in time slot N*8+0 (/S0) the current 8-bit value of channel N is presented to the DAC by loading IC19/20 - in time slot N*8+6 (/S6) the input to the DAC is cleared, by clearin...

Re: MAME: Hybrid Music 5000

At the risk of jumping in and muddying the waters: the 6070 has two modes, nominally ADC and DAC, which in the Music 5000 are both used as output modes (because the ADC mode is meant to be used as a successive approximation approach and therefore also operates as a DAC.) So the ...

Re: MAME: Hybrid Music 5000

Thanks. I understand all of this from the documentation and the b-em implementation, but what I don't understand is how the hardware uses those four control bits of the stereo position to affect what is fed to the Am6070 to result in the 7 positions. What does IC24 actually do to achieve this? IC24...
