Welcome to the Forum. I've been here since 2013 but it says I'm new member for some reason. HAHA maybe because I don't usually post? What are you having issues with with the Zenith? DM me if you can, maybe I can help. I have a Zenith Z-Star ES.
 
JKnightandkarr, I have several more Green 753's if you are interested.

Regarding your Zenith hard drive issue, do you have a dead drive that you want to replace or a missing hard drive and no way to connect a new drive? If you have a dead IDE drive or at least all the hardware to install the drive (ribbon cables, connectors etc), but can't find a drive to install, try a CF card with an adapter to PATA --- CF cards under one GB are easy to obtain if that's the issue.
 
Thanks all.

My hard drive is dead. It worked, started having read errors, worked again and then up and dead. I know I could use J-key drivers for Windows and DOS and the manual that Windows 3.1 had, could be useful. Will DM as soon as the forum lets me.

I am interested, will try and get the money together, quick. Wouldn't hurt to have a back up computer, esp since an internal CD-ROM is involved, as for my Zenith, the drive is dead. I have a CF adapter, but the computer won't even power on with it installed. I did get a SD card adapter with a 512Mb card, works, but will NOT boot, unless I have the boot-disk in drive A.

Your SD card may be reporting to BIOS as a "portable" device and therefore not a boot drive. Free download of Rufus software may change the status to fixed disk and allow the SD to be a boot device. Just a guess. Or settings in BIOS may or may not allow booting from anything but the floppy. I hope not. These old early beasts weren't user friendly sometimes. Rufus will also load DOS onto the SD card.

That could be the case. I know that there are no settings whatsoever in the BIOS. I will try that Rufus software. Thanks.
 
That Rufus might have fixed it. I got the typical "No O.S." message on the SD card while it was installed! Tried to put DOS on it, but something wrong, asks for Disk 1, which was in the drive.
 
Mine should arrive today UPS, 1 day early. Too bad it looks like the CPU I ordered (should have been here today) is being held up in CA a bit.
 
Any tips for getting these to just turn on? Put in a CPU, set the speed switch. Get the power plug indicator, CD drive light flashes. CD will open and close, but that's it.
Maybe they don't have ANY installed memory? I thought they had the minimum to at least get to boot.
 
Do you see any different LCD activity (that little area between the display/keyboard with small icons to indicate power, floppy, hd, etc.) with the CPU in?

I think they have 8MB on board.
 
No LCD activity. I think it's a dead CPU. It was an old 120 I had laying around. Have some others on order.
 
There's 8MB RAM on the mobo and it should boot with just that. Make sure the CPU socket is locked closed - push from the back toward you to lock with a screwdriver in the back CPU locking slot. It should "pop" when closed. Push from the front to release. But also make sure the SW1 and SW3 switches which are behind the CPU socket (hard to see) are set for as follows: SW1 off,on,off.on (120MHz) and SW3 - off,off,on,off (3.3volts) Also, this system is slow to boot - make sure to wait for it. It should beep before the screen turns on. Also, the small LCD display should have icons come on when it powers up. If you think the CPU is DOA, and if you are willing to it to me, I can test it for you. But after turkey day since I'm traveling.
 
Got is started. The trick was making sure the socket was clicked into place. Now I need to get some boot media created. Thanks.
 
My SODIMM"s don't fit - they are close, but the side that has the notch runs into the connector. Are there variants of SODIMM that won't work?

This is what I have:

I got mine all booting up DOS 6.22. Now I need to find memory. The manual is woefully sparse in specifying the required memory.
UPDATE: WFW 3.11 at 800x600 and 256 colors running. I miss the 'Rugby' color scheme.

Memory goes in at about 45 degree angle and then press down to lock in place. There's high and low notch SODIMM and both types should fit in the Green 753. Yours appear to be low notch. The plastic tabs on the sockets can be stiff and gently pushing them to spread them while pressing down on RAM to seat helps too.
 
Here it is - maybe they put the wrong sockets on it or something? This is as deep into the socket it will go given the plastic guard on the top left, which is to say not in the socket at all.
