The mug is a very nice touch. Don't know whose idea it was, @exxos or @Icky, or somebody else? But I like it a lot

Having breakfast with a very special atarian coffee!

I got as far as building an ST binary, but I've no idea about TOS/GEMDOS/XBIOS or indeed 68000, so it'll probably be a while before I can write that program, assuming it's possible... From what I've gleaned so far, keyboard and midi share the same interrupt, so it wouldn't be a case of just disabli...

Probably yes.

I re read the thread because I think I misunderstood the issue. I thought the problem was related to software using MIDI, but seems it's actually software that does not. A long cable conceivable can provoke a MIDI interrupt. It won't flood the hardware, as said, it won't be able to generate interrup...

What might happen if the higher priority interrupt is constantly firing? I'm thinking, for example, of severe noise on MIDI ports causing it to think its buffer is full? The MIDI port can't provoke interrupts at a higher frequency than the configured baud rate no matter what. This is basically true...

In previous systems at work (on ARM processors), I've used processor exceptions to handle some "out there" cases, and I think it could be done here too. If, at boot, we set Physbase / Logbase to point to some unmapped memory address (for the entire 32K/150K of screen RAM) and install an e...

A bit of column A and a bit of column B. It’s possible to bus-snoop to get Pokey data, and then implement a Pokey core (or two, for stereo) on the FPGA to reconstruct the sound, but you don’t get SIO audio, as you point out. I actually wasn't talking only about the analog SIO audio. But also about ...

I had thought of the SIO audio - and because I don't need all 36 data lines on the XL/XE, one of them is used for audio. The RP2040 has a circuit which converts the voltage levels to ones appropriate to its ADC, and injects audio packets along with the bus traffic coming from the host computer. It ...
