Comment No big secret (Score 1) 138

This would be fairly easy to produce. VHF radios are available cheap (Wouxen, Baofeng). Getting WIFI throughput would be all but impossible due to the necessity of using a much narrower than the 20 MHz channel WIFI uses at 2.4GHz.

Hams have been transmitting digital packets via radio over much father distances for over two decades. True it was only 1200 baud but I could see much higher speeds with much more modern DSP capabilities.

More than likely they cancelled this due to potential liability issues.

Comment Lexmark case (Score 3, Insightful) 649

Printer manufacturers tried this several years ago with chips in ink cartridges. The supreme court ruled it was ok to reverse engineer the code on these chips if it was required to allow other companies to make make compatible cartidges. I would think the same would apply to cars and after market parts and upgrades.

Comment No Interlacing (Score 2) 113

The video produced by the Apple II is not interlaced at all. Many video devices used to mix and overlay video in studios had trouble with this fact. True the video memory is not sequential but that's not the same thing as interlacing. Way back in 1983 I had lunch with Woz and a half dozen or so mostly game developers at the Independent Developrs conference. I asked him if he would want to change anything about the design of the II. He said he might add the two chips needed to make the video memory map sequential. Several of us including myself said that most of us would still use a lookup tables for updating video memory anyway (it was faster) and that didn't really matter much. In the end he agreed.

As far as the 6502 being the shittiest processor of it's generation I would have to disagree. True it has fewer registers and instructions (RISC?) than most even older designs like the 8080, but it did have some unique adressing modes that made it the perfect processor for the graphics the Apple did. This coupled with the fact you can use the 256 bytes of zero page much faster and much like processor registers (indexed memory referencing) made it one neat machine.

You might have mail.
