Zenith Z-150 "Beige Label" Build Help
Posted: 29 Aug 2021, 01:11
TL;DR: please give me the pinout on the PCB side for a Zenith Z-150 AT or sell me a cable!
===============
I have an AT version. That's the one that has the "beige" logo, model 100-1860. It has a cut cable and I just spent a few hours trying to get a standard Soarer's Converter to work. No luck.
* I have a bit of cable left inside the Zenith's case, so I know the cable colors were (north to south) black, red, white, green, and yellow. There's an extra black cable ... in the cable, itself, for grounding on the PCB.
* The Zenith colors don't follow the IBM DIN-5, which has black for VCC, red for data, white for ground, and yellow for clock.
* The Zenith is supposed to have an extra line for Reset. I think it's the Zenith's green cable. Soarer's Converter uses pin 7 on the Pro Micro for that. Didn't work for me.
* I did check to make sure my Soarer's Converters worked on other keyboards.
Oddly, there's a bunch of info here and on the web about the black label -- i.e. XT version -- of the Z-150.
