[GreenKeys] Model 28 computer interface board

[MANUEL MASEDA]

Several people have asked me about the computer interface board I mentioned in my 28 for sale ad yesterday.  Info on the board can be found on the deramp.com website by Mike Douglas.  Mike is a big retro computer guy in Dallas and makes some really neat retro boards.  You can find his videos on YouTube at deramp5113.  He has used the board to interface both the model 15 and 28 to various retro computers.  As I mentioned it does bidirectional Baudot to ASCII conversion at multiple speeds and also has an audio interface that can be hooked up to computer/tablet to receive feeds such as ITTY.  Mike sells it as a bare board and all the parts can be purchased at Mouser or Digikey. It’s very easy to assemble. Here is a link to the manual.
