First power on for my Nabu and looks like I have a bad DRAM chip, U22 according to the Nabu PC Diagnostic manual by Rudy’s Retro Intel. Thanks Rudy for putting this together.

I have had adapters built to hook up a PC parallel cable and tested with a retroprinter and it works great! Leo's pinout on his video was perfect.

I am offering premade rs422 cables for the NABU which can optionally include the usb adapter. arcadeshopper.com

I am now offering printer adapter cables in my store at arcadeshopper.com this will allow you to use a standard "PC" parallel printer cable with the 25pin connector on your NABU
