Looking for manuals for Heathkit/Zenith H-29 / Z-29 serial terminal.

[bladamson]

Hey folks. I can't seem to locate a scan of the manuals for this terminal anywhere online. If someone has a print copy in their archives, I'd be willing to pay a security deposit and shipping both ways if you'd let me scan them. The Zenith version of the manual is probably just an operator's manual and schematic, while the Heath manual probably has assembly instructions. I'd be happy with either/both, or with any other configuration/schematic information anyone might have.

Thanks very much.

I'll answer my own question, lol. https://ia801508.us.archive.org/9/i...43-02_Z-29_Users_And_Technical_Guide_1983.pdf

There seems to be an opinion that the Morrow MDT-60 is a rebadged Z-29. I'll let you decide.

They do look remarkably similar. Terminalwiki suggests that the Z-29 uses an 8051 whereas the Morrow docs say that it uses a 6512.

When the machine arrives (assuming it isn't vaporized in shipping), we can find out for sure.

Well, the thing got damaged in shipping somehow. Box looked fine, but no high voltage on the CRT, even though some of the pics showed text on the screen. Grumble.

Anyway, I took some photos of the logic board, to see if it's the same or similar to the MDT-60. Haven't had time to compare it to the Morrow schematic yet, but here are the pics anyway.

 

[bladamson]

Yeah, the P8031AH is an 8051 uC. The MDT-60 uses a 6515 IIRC according to the schematic (or some kind of 6502 derivative anyway).

They must use the same enclosure but different logic boards.

I can only speak for the keyboard, but the Morrow MDT-60 uses the same keyboard as the Z-29, Z-39, and H29, and it's a pretty specific keyboard. I'm using one on my Z-39 right now.
