  1. If I'm understanding this correctly, I think I might qualify... See here. Haven't done much yet, though -- so many parts to order, so little money. Whatev, I'm used to it
  2. Mine finally shipped! OMG I can't wait to get it! ...yeah, I'm excited, why do you ask?
  3. Mine still says "processing" What the heck does that mean?
  4. Hey, pardon what I suspect is my general stupidity (good thing I'm not in the military!) but what does "processing" mean in the case of my order for one Stellaris Launchpad?
  5. Hadn't thought of that. What work I do usually gets planned on perfboard (i.e. I draw it out by hand on a picture of the perf, then solder it together). I'm not much of one for breadboards. Guess it shows
  6. The pin spacing is what tells you. If they are spaced in increments of 0.1" on the board (the pin-to-pin distance is that, IIRC, but I don't know about header-to-header distance) then they will work in a breadboard just fine. OT: _txf_ I love your avatar. Where did you find that picture?
  7. Looked on eBay. They are there, but I don't really feel safe ordering from China/HK. I'll think about it, though.
  8. @Igor: I'd rather spend $10 and get 16mb RAM than mess with those dinky SRAM chips. The real problem was that I stupidly thought 16k*8 was 128M not 128k. I feel like an idiot for that one -- and rightly so! @abecedarian: looks like those chips are not sold anymore, and quite honestly it's far easier for me to borrow someone else's work that gets me 90% of the way and get the rest of the way on my own. With Blondihacks' circuit, all I have to do is figure out how to interface it to something 4 times the speed. (The Atmel chip she has is 20mhz and the Stellaris chip is 80mhz.) I'll probably also have to do some slight adjusting as Blondihacks uses a -PA chip which has been discontinued and I'll have to use the -PU chip. Not sure what the differences are, but I'll probably find that out pretty quickly.
  9. Think I may have the video figured out already! It was right in front of me and I didn't even see it. Hackaday a short while back featured the work of one Quinn Dunki -- aka Blondihacks -- and her attempt to build a 6502-based system essentially from scratch. I'll be copying inspired by her work and using something nearly identical very similar to what's shown on these pages: http://quinndunki.com/blondihacks/?p=955 http://quinndunki.com/blondihacks/?p=980 http://quinndunki.com/blondihacks/?p=1059
  10. OK, been in contact with the guy who did this, and he has been extremely patient with me and extremely helpful to me. I'll be implementing a version of his emulator for this project... and using rather similar hardware. It seems that SPI SRAM is a bit expensive after all -- I was converting kB to MB in my head for no apparent reason -- and can't be used anyways. Linux only supports "directly accessible" memory -- that is, parallel-address RAM. Among other things, Mr. Grinberg pointed me to a website that is selling 16mb 30pin SIMMs -- the largest size of that (antique) RAM that can be made due to pinout limitations. They're cheap! So here's what I'll be looking at... Storage + Swap -- SD card w/ swapfile + OS + data RAM -- 16mb 30pin SIMM (60ns access time, wheeeee!) Video out -- TBD... but it probably won't be color...
  11. Order Date: 9/1/2012 Est. Ship Date: 11/02/2012
  12. Just discovered this. Looks very nifty -- it's an FPU that should be nearly universal -- this is very useful for linux ops! As for MMU, wouldn't it be possible to program a PIC for that? IIRC, a PIC can do nearly anything short of delivering pizza or washing dishes. Just sayin'.
