I’m intentionally moving very slow on the next Sentinel spin. First off because the current spin hasn’t even been shipped. Second because I want each new spin to address every flaw and bug in the previous. Third because it’s not fair to just immediately obsolete hardware people just got.
It will be at minimum several months before the new spin is ready for production.
It’s not that I want to pack in more features. No, I just want to ensure that what’s there is what’s needed, and what’s there works as intended.
In fact this new spin removes several potential features, to make room for the keyboard, which I consider essential for long term usability.
I also want to use the time to design some example cartridges. A ROM cart, a RAM expansion, maybe some kind of I/O thing.
@mos_8502 question: does the cartridge slot have audio passthrough pins? Could we make synth expansion carts?
@elfi I would like it to have. I just don’t know how to design that.
@mos_8502 the latter might be viable then, if you can source the parts without too much cost
@elfi That’s what I’m thinking. Opamps are cheap. There has to be one in production that can be used to mix two stereo signals.
@elfi From what I can tell, the Famicom just sends the audio to the cartridge, which either handles mixing or passes it through unchanged. The SNES uses opamps to mix three audio sources.
