Looking for Manual for Heath/Zenith ET-100 Learning Computer

[BrianTWhite]

Hi all
I recently acquired a Heath/Zenith ET-100 Learning Computer. It has a keyboard on a cable and a big solderless breadboard on the front. I've found some mentions of similar things on the web but not exactly this.
I'd like to get it fired up. Does anyone know where I might find a manual?
Thanks
Brian

Sent the link.

Is yours the basic model or the EA-100 with support for color monitor and floppy drives?

Picture of the rear connectors?

Brian,

I also have the Heathkit ET-100 & keyboard (base model) Maybe we can take the journey of exploration together.

My unit powers on. I am missing the original keyboard cord so I built one with RJ12 6 conductor but no luck. Can you confirm the pin out of the cable? It appears to be straight thru.

Mine was built as a kit so I need to verify it was assembled correctly. I have no idea if it ever worked. I will continue to investigate.

Please keep me posted on your progress

Nick
