Interview with Martin Hejnfelt

Here’s an interview with the creator of the 129x and 68x “homebrew” input cards for Sony BVM/PVM monitors.  Anyone who’s into retro CRT monitors has probably heard Martin’s name quite a few times over the past few years and it was an absolute pleasure to interview him.  As usual, it’s a very laid back conversation about beer, our travels…and of course, how Martin was able to reverse engineer the 68x, after it was deemed “impossible”.

Here’s some videos I made showing Martin’s work.  I definitely suggest them for all fans of Sony “professional grade” CRT monitors:
