  1. The #KITT effect circuit that I designed and simulated in #verilog actually worked at the first try. I'm surprised.
    It's done with a 555 and a bunch of 74 ICs. Nothing fancy.

    It's also totally useless, unless one needs to drain #cr2032 batteries watching #blinkenlights

  2. Multithreading? Virtual memory? Supervisor mode? Floating point? Multiply and divide? All unnecessary! The 1802 doesn't even have a subroutine call. Or a dedicated PC register.

    As for computers, well, they certainly don't need sound. Or video. Or keyboards. See Lee Hart's membership card:

    You *do* need blinking lights though.
