The time it takes to "correct" your operands and result is insignificant compared to the actual multiplication. Although, on 8-bit that may not be as true ...

Well, the flag would be reset if the batteries are removed. It's likely for benefit of interrupt events that can occur when the calc is off. Link port, on key. Then again, I know nothing of TI-OS ...

Yeah, same here. test.asm line 3: Failed label or macro SAVER. test.asm line 3: Failed label or macro IY. Failures are due to the misinterpretation of iySaver due to matching to (iy*),*. I haven't tested, but I'm certain TASM can't handle this even though it has a specific instruction class ZIX . Th...

You can also see that the calc's in halt when you're on the homescreen. In addition to coordinating timed events, the interrupt saves power.

That won't be possible. Although internet traffic always has more than one way to reach a destination, the shortest and usually quickest route inevitably passes through some big companies' servers. AT&T/SBC and like companies have themselves in a bit of trouble. To offer their services, they're ...

I thought the speed problem was because of this host, but it ends up it was in the offsite images. Very quick now, nice fix.

Beta, bah! All I've had is dungeon testing so far.

A little off topic, but bc can be loaded from RAM. ld bc,(*)
It's a prefixed opcode, so it's four bytes instead of three, but still less than transfering from hl.
In most cases, it's quite safe to use xor a as a substitute for ld a,0. The only downside is that it destroys your flags.

There's only one useful maskable interrupt on the hardware/software setup we're using. Normally with Z80 the interrupting device puts a byte that refers to its service routine on the data bus, but for us, that byte is random (that is, there's no distinction between what generated the interrupt). So ...

Stick with four. Higher level isn't worth the size (some may debate that that's true with four also).

Oh, yes definitely. Knowing that your game will have an audience (even if it is a bunch of kids) is good to know.

Many of us will continue as long as it's still fun. It is after all, a very cheap hobby (especially if you purchased your calculator for a separate purpose). The calculator is a platform on which you can do things that haven't done before. For me that's the appeal. Why make a mediocre PC game when y...

Personally, I see nothing wrong using your display so resourcefully. Keeps the code small and simple, I'm very impressed. Only thing that's keeping me from using PTI is not lack of "Step Over" (haha) but rather lack of VTI-style force loading. I very often send over multi-page apps and I'd...

The best way to consider the new controller is as a 3D mouse. I think it has potential.
