Thirty years later the ZX-TEAM decided to build a 100% software compatible clone but with stereo jacks to be connected to an standard PC amplifier.  Latest layout will be a standing version, like the original ZON-X with a guided through port. So you'll can connect your memory expansion or whatever behind the MrX card.
