All;
What are people using to make up the appropriate female cable-end 15x1 connector and its fittings?
Cost-effectively, of course :->.
The one that I see in Glenn’s photo is marked 134-1022, FYI. I haven’t been able to reverse-engineer that into anything :-<.
Thank you,
paul

I seem to have four original Heath serial connector cables for use with the H-8-4. I believe these are WH8-41 wired per the spec’s in the following:

I created my own cable to connect from 15x1 to DB9. I can provide the connections from DB9 to DB25 if needed. Using DB9 allows me to use the USB to DB9 adapter cable to use it with my laptop.
P603/P604 on Z80 V4 CPU board:
P603/P604 to DB9 connector
Pin 1 – GND – not used.
Pin 3 – TX_Data to pin 3 on DB9 (red cable)
Pin 5 – RX_Data to pin 2 on DB9 (green cable)
Pin 7 – RTS to pin 7 on DB9 (blue cable)
Pin 9 – CTS to pin 8 on DB9 (yellow cable)
Pin 11 – DSR to pin 6 on DB9 (violet cable)
Pin 13 – GND to pin 5 on DB9 (Brown cable)
Pin 14 – DTR to pin 4 on DB9 (White cable)
Pin 15 – RLSD to pin 1 on DB9 (Orange cable)
There is a gray cable left, so I connected it to DB9 pin 9 (RI) if needed in the near future. The other end not connected to the 15x1 header.
I bought the following cable from Jameco (25ft for $11.95 + shipping) https://www.jameco.com/z/SC9-25-Jameco-Valuepro-Multi-Conductor-Cable-9-Conductor-Stranded-24-AWG-Shielded-25-Feet_644412.html
Thanks,
Norberto

Thank you and Glenn both for the additional information. So the printed PN is from Heathkit; aha!
I’m thinking that the “subtext” response is that since this is 0.1” pin-spacing “just use one side of any IDC-style 15x2 connector”?

Thank you Norberto. So Molex KK-series, the missing clue. Seem to be much more cost-effective at Mouser:
https://www.mouser.com/ProductDetail/Molex/22-01-2151?qs=U%252BuvySh%252BEcnuR7S0EURgzw%3D%3D $0.61
https://www.mouser.com/ProductDetail/Molex/08-50-0106?qs=zi95yC3thwEn8WhcIJBXDA%3D%3D $6.70 per 100+
I see that Pololu is running a sale until Monday: https://www.pololu.com/blackfriday2021

So one very nice feature of the Pololu model that some others don’t have is the step up/down feature. For example, the EZSBC one requires at least 7.2 V input, so it’s a step-down only. With the Pololus I can swap boards at will between systems that have the linear H8 supply (8V) and those that use PC ATX supplies (5V).
