ZTX-1 schematics / docs?

[Joseph Travis]

I recently acquired a dead ZTX-1 terminal which has suffered damage from a leaky battery.  I'm hoping someone in the group might have the schematics and documentation.  Thanks!

Heath Kit version was HTX-10 Serial Terminal

This Keyboard and Desk enclosure was used by Heathkit in other products,

like HD-8999 CW Keyboard (1987 Christmas Catalog, page 28)

Thanks Greg.  That's pretty much all I found too.  Still no schematics.

I'm hoping to repair the ZTX-1 and upgrade it to the ZTX-11 which will require some additional circuitry and different EPROMs.  It has a nice keyboard, similar to the H/Z-29 or H/Z-100.

Regards,

Joe

I have the ZTX-10/11 Technical manual and schematics. Not sure how different the ZTX-1 is, but I won't have time to do a proper imaging of them for a while. I'll try to get some photos of the schematics and send them to you in discord this weekend.

That’s a very handy Wiki. Thanks!

That would be perfect Mark!  The ZTX-11 is an upgraded version that also has a serial port (which requires an additional cirquit board and different EPROMs).

Can I get a PDF copy of it?  Or can I buy / beg / borrow it?

Thanks!
