  1. Re: US Air Force Moves Forward with High-Power Microwave Weapon

    The video almost said nothing - it was all quite sanitized, but that was to be expected since it is aimed at the public. The fact it was made at all does indicate that it is operational and has been...

    Re: The New 16-Cog, 512KB, 64 analog I/O Propeller Chip

    I don't know about USB being a mess. It works and pretty darn well. The only question is whether or not the P-2 can emulate it software, if it can't then it means the P-2 is dependent on 3rd party...
  3. Re: Can a propeller be used to drive a Z80 at 4 MHz?

    Sowerbutts also has a FPGA version of the Z-80 running but his is at 128 Mhz using the T-80 cpu core(from opencores.org). Though he doesn't use SRAM but SDRAM 8MB also running at 128Mhz. It runs CPM...
  4. Re: Any ideas how to hook 5 year old girl to electronics/engineering?

    Thoroughly nightmarish. As one doctor and critic of the scheme stated, "there are things worse than death" and this being on of them.

    Re: Dark Silicon

    Well the drama has been going on for 8 years now and still no sign of a P-2. I think it's quite fair to question whether or not we'll ever see a P-2.

    The easiest computer to build and understand would be a 1 bit MC14500 Industrial Control Unit.

    I hope Chip isn't listening. The last time he listened to the gurus they turned the P-2 design into a fiasco.

    Porting hardware dependent code is a real bear, and it's made worse when the target platform is really different and has it's own limitations. Sometimes it takes a complete redoing of the...

    Mickster used a valid form of Basic and it can handle what you did in C and is much more readable than C.

    The fact is Basic evolved over time just like C which became...

    Dirt cheap CPU cycles and near infinite memory pretty much squashed the need for fast, tight code.
