Zenith Z-171 Z-170 ZFL-171-42 : XT-CF card

You mean the XT CF card? I have blank boards. Are you able to solder fine pitch things? Or do you need assembled? Do you have a CF card?

I had pretty good luck using a serial transfer cable and laplink 2.
 
I think the easiest thing to do is to upgrade your uard to a 16550. Then you can do fast file transfers with laplink. That gets you going with ability to download programs. Save on the 360k floppy....

I didn't even know I could do that!
How did you set it up? I only have modern systems. Would emulating it through something like dosbox work?
And I assume by 16550 card you mean the expansion modem card? My Pivot II comes with the Modem and the video card, but not ram.

I wouldn't be able to solder anything because I live in a dorm. There are smoke detectors in every room. I'll give Laplink a try once I get it up and running.
Speaking of me not having the expanded ram, how did you go about upgrading your ram? Did you just put higher capacity chips where the old ones were?
Thanks for the advice!
 
Mine came with 640k installed. I later did a 1M upgrade which I since removed.

Share a pic of your memory board. Probably it is upgradeable.

Your machine has a a stock serial port based on a a UART chip on the main board. You can buy a better UART chip, a 16550, and get much better performance. It plugs right in. You can search here for 16550 to get an exact part number. Or I will post it here.
 
Twospruces,

I just joined this forum after following threads about XUB and the Z-171. It looks like you did a great job working through all these problems with this early machine so thank you and great job.

I just resurrected one of these units to add to my collection and would be very interested in getting one of your XT-CF boards or at least the Gerber file for it.

Having just joined, I don't have enough posts to DM but I thought I would post here as I am sure others who might land here might also like to know if and how we can build or buy your boards.
 
Happy to share what I have.
The trickiest part is getting a CF card socket. I should post close up photos of the part that fits.

I'll have to go back and see if I can replicate the XUB correctly.

Sorry for the necro post, but is there any way I may get one?
I recently got a Morrow Pivot II, and I'm looking for ways to get files from a modern system to it.
Have you been working on any other modifications? I'm super new to this stuff, but I want to modify my Morrow II. Assuming that it works though! 😅
Oh, and speaking of which, would you happen to know the dimensions of the end of the 12v 3a power supply? The unit I bought did not come with one, and I don't know the exact size of the barrel plug.

Mmm, Necros...

I just got a Zenith without the power supply and I got lucky in that I found a perfectly good power supply for it.


No need for an adapter plug, and the polarity is correct (tip positive) on the cable coming off of the supply, so don't use the short jumper because that reverses the polarity of the plug. Set it to 12 volts *BEFORE* you plug it in.

Here's the listing for when the link evaporates:

SHNITPWR 3V ~ 24V 3A 72W Power Supply Adjustable DC 3V 5V 6V 9V 12V 15V 16V 18V 19V 20V 24V Variable Universal AC/DC Adapter 100V-240V AC to DC Converter with 14 Tips 5.5x2.5mm 4.0x1.7mm 3.5x1.35mm​


Mine also came with a working boot disk.
