  1. Pico's usually get fed +12v through the round connector. The other connectors are outputs.
  2. That is odd, I have a PicoPSU on my Falcon... works great.
  3. To start an ATX power supply, you have to short pin 14 to ground (pin 15, 16 and 17 are all grounds). Both of these pins are on the power supply side, has nothing to do with the falcon. Normally you connect a momentary contact switch across 14 and 15.
  4. ATX power supplies need a wire grounded to start up. Look here: http://www.instructables.com/id/How-to-power-up-an-ATX-Power-Supply-without-a-PC/
  5. ... and don't try to paint the whole screen in one frame. you don't have enough time to do it.
  6. Sent an email, got a response right away. Awesome Thanks!
  7. Actually, I did. Most of it is posts of the "I sent an email and never heard anything back what do I do now" variety. Hence, asking for current process to avoid the same issue.
  8. Well, I'd definitely be interested in a copy. What is the process to register for batch #2?
  9. Moving day is Wednesday! Save me the trouble of packing this stuff up! All reasonable offers accepted! Thanks!
  10. Moving day is wednesday.... Don't want to have to pack this stuff... All reasonable offers accepted!
  11. A wasn't all that bad. I'd definitely use it over B.
  12. I'd imagine all but the cheapest UPS would have some large caps on non-sinusoidal outputs to smooth things out. You cant send out unfiltered PWM power.
  13. Best Electronics TT Diagnostic Cart v1.5 $25 shipped in the US Thanks!
  14. last week before we move..... all reasonable offers accepted!
  15. Not to flog a dead horse, but I didn't see anyone fix this... "Back in the day" our 15 kHz display devices expected more or less a 30 Hz interlaced NTSC-like signal. The odd frames would display 262(ish) odd numbered scan lines (1,3,5,...) The even frames would display the even numbered scan lines physically interleaved with the prior odd lines (2,4,6,...), the phosphorous in the display and the persistence of vision in our brains combined the two interlaced frames into a single 525 scan line frame at 30 Hz. However, our 15kHz devices of the day (ST's, A8s, etc) only had 240 (or so) lines of data, so they simply output the same frame twice, and didn't include the burst telling the display to switch between odd and even frames, which caused the display device to paint the the odd and even frames on top of each other, rather than interleaving the scan lines, giving a 60 Hz frame rate with half the vertical resolution. On CRT's you get the 'blank scan line' effect, because the electron gun never physically paints the 'even' parts of the screen! When you move to an LCD, doubler, or upscaler, each scan line gets repeated, 'filling in' the 'blank' even scan lines with a copy of the odd ones, resulting in an image where all the pixels are painted twice as high, with no vertical gaps. Whether this is an improvement is very subjective, however, it is substantially different from "no data".
  16. bump. Make offers, still lots left!
