Some progress with my SVG processor!

Leftmost: original SVG
From left to right:
8-bit renderer
32-bit renderer (256 colours)
OpenGL ES renderer (24-bit colours)

The colour differences between the SVG original and my renderers can be explained by me not parsing the opacity

Another for #TI994April -- that time someone called in response to an ad I had placed in the paper to sell my well-expanded TI-99/4A system ... to convince me NOT to sell it, back in 1984.

This is a '99er.

Check out this TI-99/4A setup ... collection ... room. It's the most impressive TI-99 situation I've ever beheld. Just, wow. Posted by John Carr on Facebook, showing the culmination of his lifetime of collecting.

Got my new #TMS9918 video card for my #RC2014 from @shieladixon today! Along with the YM2149 card I already had, I now have more period-accurate hardware for the Z80 CPU.

Using NTSC composite on a modern flat-screen TV is not ideal, but it all worked out, once I read the instructions on the jumper configuration, out of the box. Looking forward to exploring this more - and maybe, in the process, learning enough to help me with the TMS9918's evolutionary descendants in the Master System and Mega Drive.

Updated my online TI #TMS9918 based VDP #calculator that still needs a better name. :)

There's an option to disable unused registers.
