• Retro Challenge 2017/4 - Rack Teardown and Wrap Up

    Ok, firstly, apologies for the lateness of this post.  The stuff below was actually done a couple of weeks ago, but time has just got away from me.  Hence this is being written up 2 days past the closing date for RC2017/4.  Sorry
    Anyway, this part of my challenge involves investigating a rack that came as part of the old stuff that I picked up.  Looks like a 3 bay x 12 slot Eurocard rack.  Lets take a closer look...
  • Retro Challenge 2017/4 - The Key(board) to Happiness

    Next up on the things to investigate is the 4 keyboards
    Judging by the connectors, it was obvious that these aren't modern (PS2, USB or even 5 pin DIN) keyboards.  Likely either a raw matrix or maybe parallel ASCII.  Lets open them up and have a poke around!
  • Retro Challenge 2017/4 - Getting The Excuses In Early

    So, once again Retro Challenge is upon us, and, yes, the timing is offset , but an April challenge should mean that more people are able to participate. To try and stay ahead of the curve this time, I thought I'd get in early and give my excuses for why I failed to complete the challenge this time around.  I know most people leave this part until the very end, so hopefully I can impress the judges with my efficiency! The very first weekend in April was the UK Maker Faire in Newcastle (which was awesome, thank you for asking), so that took 3 days out of April for me. Then at Easter the Edinburgh Mini Maker Faire will also be robbing me of 3 days.  And, finally, Vintage Computer Festival Europe is on from 29th April to 1st May.  So, with travel and prep for these events, I feel like I'll be left with about 4.5 days in which to complete the challenge.  Lets see how that works out...
