| 09:09 | | * McMartin fiddles with his Commodore. |
| 09:09 | | * McMartin deploys the little-used 24-and-a-half-row text mode. |
| 09:10 | | * McMartin *also* gets a preposterously tricky thing to work right. |
| 09:10 | <&McMartin> | And with timing slack that's just good enough to handle both PAL and NTSC timings without needing to actually check where it's running. |
| 09:12 | <&jerith> | \o/ |
| 09:13 | <&jerith> | I wonder if I can find an adapter suitable for plugging my C64 into an old VGA CRT display. |
| 09:15 | <&McMartin> | ... that would most likely be an RF Demodulator with VGA out. |
| 09:15 | <&McMartin> | (The DIN-9 video port in the back emits S/Video, which is *also* not VGA or anything like it.) |
| 09:15 | <&McMartin> | (The Commodore 128 had two graphics cards, one of which matched the '64 and one of which expected to be plugged into a CGA monitor, for sharp 80-column text and nothing else.) |
| 09:16 | <&McMartin> | Anyway, yeah, the trick is vertical split-screen scrolling with no buffer to adjust between the scroll levels. |
| 09:17 | <&McMartin> | Which you would think would not be so bad, but one row in 8 there are two rasters in a row starting a new character cell, and the graphics chip "stuns" the CPU to do the load, and does so long enough that trying to trap that raster normally fails because by the time you recover, it's too late... |
| 09:18 | <&McMartin> | ... so in that one case I revector the interrupt to one that triggers one line *earlier* and has a tuned time-delay loop of one normal line and one stunned line before proceeding to the rest of the interrupt routine. |
| 09:19 | <&McMartin> | Then, as long as I'm doing crazy cycle-counted time delay loops, since this is triggering for the last line of text on the screen, instead of having a "start of VBLANK" and "right before the last line" routine as separate interrupts... |
| 09:20 | <&McMartin> | ... After I set up the last line I wait just enough cycles to finish drawing the screen and going back into the bottom border, and then execute the top-of-screen code, thus giving me a thousand or two extra cycles to work with each frame. |
| 09:20 | <&McMartin> | As an added bonus, that ended up making the raster code *smaller*. |
| 09:21 | <&McMartin> | (Granted, by 15 bytes.) |

| 16:16 | < abudhabi> | Any way to 'sync iPhone photos to PC'? Presumably, automatically? |
| 16:28 | <~Vornicus> | the itunes system should handle that, typically |
| 17:56 | < abudhabi> | I'll try. |
| 17:56 | < abudhabi> | Anywho, how does one control the presentation of a Double in Java? I'd like to convert it to a String that doesn't use scientific notation and truncates decimals to two places. |
