I have a Zenith 158 and no keyboard. Looking to purchase a working one (5-pin DIN). I have a PS/2 MS Ergonomic KB that I used a 5-pin to 6-pin adapter. The system says "No keyboard found" and won't boot.

Can anyone help?

thanks

If you just want to use any keyboard, make sure you get an XT compatible one. Some keyboards have a little switch to change between AT and XT.

XT is not wire compatible with PS2, that might be the reason your converter doesn't work.

Z-150s are strange keyboards. XT was not designed as an open, interoperable standard. (I doubt AT was originally intended that way either but it had more time to establish itself and is easy to work with.) Apparently, Zenith XT keyboards confuse most XT converters, as discussed (and hopefully solved) here:

The reverse is also very likely. Your Zenith host is not guaranteed to work with any random XT keyboard. You really want a matching Zenith KB. There’s a chance the definitive XT board—IBM’s PC/XT Model F—could work too, but Zenith only really intended their own keyboards to be connected.
