Re: How can you tell Resistors from Inductors ?

It seems like the resistors always have a beige body, whereas the inductors have light green.

Re: AnyCPU forum

and after AnyCPU was formed, Chuck told us about this one. There's some overlap between the various forums I'm on of course, but I can still see them addressing different fields.

Re: Math Toolkit for Real Time Programming

That was at this topic, and as it developed, someone brought up that the download was probably illegal. I called the publisher listed, and they said, "That's not our book." Then I emailed Jack Crenshaw himself and he didn't even bother to answer. Apparently someone with an ACM Digital Library member...

Re: Microchip Serial Eeprom Cross Reference Guide

So far I²C ones top out at 128KB. I would welcome much denser ones because they are easier to use than the SPI ones (I'm using a tiny 4Mx8 SPI one right now in SO-8); but because of I²C's relative slowness, we probably can't expect the industry to ever make them in greater density. Large files (like...

Re: Free: Building your own 6502 computer (article)

Many parts of the 6502 primer are applicable to practically any digital project. I am actually looking at using the SWINSID which is an emulated version of the SID chip used in the commodore 64. I will be using it for my latest LED game! That ARM-based one is at http://www.swinkels.tvtom.pl/swinsid/...

progressions from ham radio to home-made workbench CPU, PICs

My early interest in electronics (1970's) was in stereo and amateur radio, not computers. Remember the line in the movie "Pirates of Silicon Valley" where the executive, puzzled and tapping his pencil on the desk, said slowly, "What would the common man want with a computer?" (They must have had som...

Re: Hi from Chuck

The bootloader idea comes from "pulling yourself up by your bootstraps" or getting yourself going without help. The computer needs instructions to do anything at all, but how does it get them if, without having them first, it doesn't know how to get them? Enter the bootstrap loader, enough of a prog...
