Yeah, I have been dealing with some trigonometry in a project I'm currently in the "thinking really hard about it but not yet writing anything down" stage. And the realization came early that the X16's BASIC was slightly lacking in trig functions. All I'm worried about at this point is 'is this project even possible' so I just thought about "soh-cah-toa" and realized that it was doable to work without a full complement of inverse functions. And that's as far as it went.

Arctan is in BASIC V2, as ATN. The others aren't. There's math that can be done using the arctan function and the understanding that the radius is always 1, though.

I was only thinking of how you'll probably need a PS/2 mouse for your X16 when it becomes available.

At this point it's probably easier to buy a PS/2 to 1351 mouse converter. https://www.ebay.com/itm/164496390269 https://www.pcbway.com/project/shareproject/PS_2_Mouse_adapter_for_Commodore_64__1351_mouse_hardware_emulation_.html https://retrocomputerstore.com/products/ps2-to-1351-mouse-adapter-for-commodore-64-c64-128-c128 https://www.tindie.com/products/baldengineer/commodore-1351-to-ps2-mouse-adapter/ Or just search for '1351 mouse converter' on your search engine of choice.

Greg Nacu's C64OS has dealt with making user interface/experience elements out of characters by... redesigning the font. Sort of like the old Apple MouseText. We don't need to reinvent the wheel here, necessarily, though... @JimmyDansbo's VTUI might be useful as a starting point.

You want to know how to group things logically? You should probably take a cue from Adam Savage: The answer to "where should I put this?" is always the same as the answer to "where would I go first to look for it?"

I haven't read anything about it. Is it based on the onboard graphics systems they've been selling for ages, or is it a new GPU architecture?

Big Commander butterfly logo splash screen. Easy enough to do, doesn't take much memory.

There's QBasic for CP/M?!?

Well, most of the Infocom games were released for CP/M, until they started including graphics, so take your pick. But the killer business apps were probably WordStar, Multiplan, and dBase II. There's also Turbo Pascal, several versions of BASIC, and a couple of C compilers.

Archive.org has a lot of abandonware, available for download or for playing on their online emulators.

That's because the program must now be started from the command line with the switch -rtc in order for the real time clock to function and produce the data for use in TI$. (IMHO, the RTC being active should be the default state of the emulator—and I'm guessing that it probably will be, once Michael has verified that it works properly and conforms with the behavior of the real hardware.)

Sven, it's quite useful to read the Wikipedia entry on the processor. It is not an in-depth programmer's manual, but it gives a surprisingly comprehensive overview of the architecture. https://en.wikipedia.org/wiki/WDC_65C816

Does it actually have SDIO support, or just SD storage?

It does change things up a bit. There was at least one run where there were only four pixels left.
