  1. Yea, using linear power supply (aka brick, with big-ass transformer) is kinda weird in 2013 Unless you have specific application, they are long obsolete. Get SMPS (Switching Mode Power Supply), it's lighter, safer, more reliable and mostly - it's more power-efficient for your power bill
  2. It's very close. http://www.youtube.com/watch?v=2uhAxFE1hUc
  3. Awww, you spoiled all the fun )))
  4. Here's the language joke only Candle understands "Two arts for me" :DDDD
  5. Am I blind or the attachment is missing in the first post?

  7. Hahaha, made my day!!!! Generated an out loud chuckle out of me in the middle of a night here.
  8. Update: debug session with oscilloscope planned but no time on my hand right now. Actually what's missing now is ultraspeed 68k and track buffer. anything else is working and just needs putting it all together. I promise myself (and Candle even more to be honest, I'd had it delayed already) to finish it this summer. Sadly, too many things with life got out of hand. The patient ones will be rewarded though Cheers
  9. well, missing the GAL part and equations?
  10. Hi, Bryan There ... 1610 LDA #$D2 for timeout 1620 F1T1 BIT DRA write 1 byte 00 at DRQ 1630 BPL F1T1 1640 STY DATREG 1650 F1T2 BIT DRA another byte 00 1660 BPL F1T2 1670 STY DATREG 1680 STA T1024I start timer $d2*1024 cycles (1024T timer) gives 215040 usecs, that would be about 0,21 sec. At 288 rpm there's 4,8 rotation per second which gives one rotation time of 0,208 sec Sounds legit Correct me if I am wrong
  11. Linux? And for the remaining 95% of the users? OpenBSD too secure to even boot
  12. Yeah, that's great. We're not competing though The more hardware, the merrier
  13. Hey after quite a while University work got in the way of development, I'm sorry for the delay. I am reinstating work on the project, n eed some more time but the end is closer. If anyone got fed up with waiting for the 1050E firmware, then sorry - it's all my fault. But now future looks promising. Stay tuned
  14. If you mean the 'desynchronisation in data area' and 'this command will not function as track copy' statements in the WD docs, I know them. The docs say also that 'id am, id field, id crc, dam, data and data crc bytes will be correct' and that only the gap info may be incorrect - which is irrelevant to the buffer. I know that what gets written is not always whats provided on the data register (e.g. F5 to FF commands ). Yes curiosity about what exactly gets written to the disk is one, the other reason is I just want to code the fastest track buffer on the planet That information should suffice and if you can provide those tracks I will be more than happy Thanks. M.
