i hope this is not a sign of Pixelmator stopping their clear, open communications of what they're putting into updates since Apple bought them :(
i always loved their clear, detailed, _effusively_ written update notes in the app store :(

Added coordinates display on lower status bar on the Atari Mandelbrot renderer. Plan is to allow keyboard input next ('x', 'y', 'z' then '-'/'0-9'/'.', backspace/enter/esc)
Using Atari floating-point ROM routines for the decimalization and ATASCII conversion from fixed-point coords.

I *seem* to have worked out my frame rate issues and it's getting pretty consistent full motion out of these demos. Note that due to "video signal crimes" the NTSC Ataris output at about 59.92 fps progressive video, not the standard 59.94 interlaced frames, so I have to fight the video capture card.

In Lucasfilm Games' "Rescue on Fractalus" you fly a spacecraft in a war zone, picking up downed pilots & fighting UFOs.
First few levels settle you into a routine; around level 8 they start mixing in alien spies!
First time this happened when I was a kid was best jumpscare of *any* video game :D

Putting the 800XL and the 130XE head to head... In addition to the cleaner video image the XE has an additional 64KB of extended RAM which I'm using to *slightly* speed up the multiplication operations with a big lookup table.

Been doing some minor cleanup on the timekeeping and perf reporting and text drawing. Have switched from ms/px to µsec/iter and next will add elapsed time in h/m/s.
Fixed a bug in my text drawing of the ASCII number output from the floating-point ROM which dropped the least significant digit :D

Made some more optimizations yesterday, have broken the 5-minute barrier for the initial view on emulated 130XE (with a big lookup table in expanded RAM) while the compatible version for 48k/64k machines runs in 5m22s.
Later I'll do some cleanup on the time reporting etc.

An 8-level zoom series on the Atari Mandelbrot fractal. In realtime it would've taken all afternoon to render them all. :D

got one more bit of precision out of the 16-bit multiply operands, which really tidies up the max zoom level :D

Last hack of the old year was getting the tiered rendering filling in 'blocks' of 4x4 and 2x2 before the final 1x1 pixel pass. Looks much awesomer than drawing a single pixel at those tiers!
