One of my first IT jobs out of university was working at Zenith Data Systems' QA labs. My job was to test newer OEM hardware on their older machines. For example, ZDS would buy large quantities of OEM parts, like Matrox or ATI graphics cards, to be put in their new machines. Why not sell those cards as upgrades for older machines? Well, someone had to actually test to make sure those cards *actually* worked in the older machines. That was me! I spent my days plugging in and testing graphics cards, keyboards, monitors, mice, sound cards, etc, on older computers and laptops from ZDS and Packard Bell (who owned ZDS at the time). It wasnt the most exciting job. However, the best part about it, was that OEMs would send in free samples of their products. Monitors, graphics cards, all the good stuff. However, unless they were specifically ordered and approved to be tested, they were not allowed in the lab. So what happened to those free parts? Obviously, we took them home! :D All that being said, they werent great computers. Just a hodge-podge of OEM parts. A lot of people only remember Zenith for TVs, VCRs, and various other home electronics. Most people have no idea they had a PC division. While they did have a home consumer market, it was small, as Packard Bell didnt want to compete with themselves. The majority of the ZDS computers were sold to schools, government agencies, and businesses that bought computers in bulk. I dont remember seeing that model there, but I have a feeling that would have been "new" or even after my time there. I also highly suspect that is not a ZDS computer. ZDS computers were not known for innovation. They were designed to be cheap and mass produced. I would bet that was a Packard Bell computer, rebranded as ZDS.

Interesting. I had both a Zenith 286 and a 386, through my uncle who worked for British Telecom in those days (1989+). I only had the 286 (1mb ram) for a few months before getting the 386 (with 2mb ram) in a swap + cash deal as I couldn't play Fate of Atlantis on the 286 (I'd got a copy from my cousin and was pissed it wouldn't load due to lack of ram). I think he also sold us an Oki laserprinter around the same time. I had the 386 for about 2-3 years before we got an Amstrad multimedia PC with sound card and CD etc from Dixons just around the time I was starting college. It was like a whole new world. Our family still remember the first time we started it up and slipped Star Wars Rebel Assault (bundled with the PC) into the CD drive and we heard the 20th Century Fox music boom out of the speakers. It was like being in a movie theatre....Dad ended up taking the Zenith to work to use for CNC programming and it was still in use up to the time he retired and the boss sold off the company, though sadly I think the new owners probably threw it out. They also had an old Compaq 286 that I gave to them which I'd acquired a few years earlier (2002) from a place I worked that had been using it as a POP 3 mail server (I kid you not). I used it for retro gaming for a few months, then gave it to Dad to take to work as another old PC there had died. He needed the older PC's to run the ancient dos CNC programming software. The first job I had after college (summer '96) was backing up all his floppy disks of CNC programs on the Zenith and an Olivetti PC he had at work.

Yep. The big difference is that, on a lot of these Pentium or earlier models, there's no persistence across a reboot and the machine sets very basic defaults and loses drive configurations and such (which usually need to be set manually; they won't auto-detect). So turn it on, it says there's a CMOS error, you set the settings and reboot and... it says there's a CMOS error and lost its settings, and it does this until it gets a new battery. Modern machines usually at least hold settings for as long as power is applied or at least can auto-detect enough to boot somewhat normally.

I remember the days of having to troubleshoot constantly to get anything to install. Hardware used to be so much more of an adventure than it is now. It’s what really taught me about how computers work.

If they released a PC in this exact dimensions with modern specs I would buy it instantly.

I was no longer a field service engineer by then and had lost contact with most of the companies I used to work in, though I do know many switched to Compaq which was then owned by HP, so the Zenith Data Systems name did die a lingering death which was a shame.

My college laptop was a Digital Hi-Note Ultra CT450T from 1994. (486/50-4MB RAM-40MB HDD-9" TFT Active Matrix Display) It had a multimedia dock very similar to this one, however everything was more compact (It was the ultrabook of its time). It also had the LCD strip for status display, but it was located alongside the monitor vertically instead of above the keyboard. The multimedia dock has a CD drive, very nice stereo speakers, and even a subwoofer. It also had a floppy wedge that you could attach to the docking port, unfortunately this meant you had to choose between floppy support and CD support which made programs that required both a bit of a hassle since you had to copy the floppy to the hard drive, map the directory to A or B and then hook up the media dock. The surprising thing with this Zenith is that despite being a full-sized dock it seems to lack both internal ISA/PCI slots and a 3.5" HDD in the dock, both of which were fairly common in docking stations of the era. BTW: I know there is at least one other video that was done recently on this same laptop that went into the various display options. I can't remember if it was LGR or one of the other channels I follow but I remember it was in the last few months.

I have the Zenith Z-Note Flex model of 1994. I got it at a garage sale for 7$ about 5 years ago. I absolutely LOVED it ! It came from Ford Motor Company and had Windows 95 installed on it. I used to play Doom and Wolf 3D on it all the time. I used to take it all over with me. Later on, I mad another hard drive I made with NT 3.51 and Windows Chicago 189 I'd use in it. Then one day, the hard drive cable went bad. I brought it to my cousin to try to fix it and he lost the power cable for it. I still have the power brick and some compatible cable I found online for what I think was a data cable to an Apple Mac of some sort. But the system won't turn on with that cable; maybe te power supply went bad. My system had the 486 and the 640x480 active matrix screen. If you would like me to send you my power supply and it's "cable" to mess with, go right ahead. I'd love to see if you are able to get my power supply to work with your unit. I tried making a new battery for my unit a few years ago and I'm not sure if I ruined my system. But in any words, I loved the video; it was great to see another person struggle with a Z-Note Flex like I did in it's later years XD

Some thoughts if you still want to get this going. Clean the ram contacts with a eraser and lightly spray the board contacts with contact cleaner. Format the hard drive to less then that amount you saw in the bios, that might be the limit the motherboard sees. Format in fat as well. Yes, as anther person typed here clean other contacts as well.. As in other electronics if they sat for a long time, turn them on with lower voltage for a period of 5 to 60 minutes to possibly reform the capacitors. use a 100 or lower light bulb in line with the 110 house going to the a computer ,or even some other device to cut down the voltage for a while or you can use a varactor o lower the voltage. If you open up the laptop or the adapter box look for any popped or bulging capacitors and replace them. Be sure your 12 volt and 5 volt power rails are close to the correct voltage and steady. I had a power supply having a problem with the 5 volt rail and it was going up to 8 volts and would crash or lock up the computer. Took me a long time to figure that one out. Weird power adapters can often be found at thrift stores in a bin you might have to dig for them or on the web.

The issue your having with the memory could be caused by either the CMOS or RAM (or the actual connectors). It's funny seeing this exact problem happening on an original Pentium. I actually had this issue on a modern system. My power supply extension cables were shorting out the computer I built. The metal connectors on the cable going to the motherboard were shortening the system out which I thought were non conductive.

Hell yeah man good work

Did you try using an external keyboard and mouse? The freezes could be a result of the dock edge connector having dirty/flaky contacts that lose connection when the top part is slightly vibrated from the typing or trackball use?

Love that t-shirt! "he seems like a nice guy!" 🤣

My god this is an emotional roller-coaster.

This one reminds me a lot of the Thinkpad 755CX, especially when connected to the IBM Dock II. Same chonk form factor, Pentium 75 CPU, up to 40MB RAM (8MB on motherboard plus a special memory upgrade card which could be 8MB, 16MB or 32MB), 800x600 TFT, even the little brightness slider on the side was the same. And the DockII is very chonky with the laptop perched on top of it, makes it weird to use. But the dock adds impressive capabilities, unlike this Zenith dock (3 ISA slots of which one is full size, 2 drive bays for either HDDs/CDROM/floppy, SCSI adapter etc). I actually have one complete with the dock and the 32MB expansion. It's among my favorite retro machines. I played countless hours of Xcom:Terror From The Deep on it.

now i am in a good mood

Wee need a modern version off this

My old 286 zenith data systems laptop still works great.

続きが楽しみ！

In the early 90s I worked In a computer superstore in England, we sold various laptops including AST, IBM, Toshiba etc but we would only ever get stock of a few at a time. Them we started selling Zenith Z series laptops and we appeared to have unlimited supply of stock (these were 386sx and 486 laptops) and we sold hundreds of them, mostly because it’s what we had in stock. I thought they were really nice computers, I bought one myself. For it’s time it was slim and light, and the screen was average.. mostly we sold mono screen laptops at that time. We also sold Zenith desktop computers, which were good. This was the era of windows 3.1 and some systems were still supplied with windows 3.0

These RAM Modules were also used in old Siemens Notebook before they switched to EDO RAM. :D edit: They were up to 16MB in size. Used in the P4D and P5D Notebooks. With 2 slots each. Siemens also produced early pentium based 'luggables', with bigger monitor and better keyboards. These used 4 of these for total max of 64MB RAM. Mine was maxed out already so I know, hehe. Only bought it for the modules since the Keyboard was missing.

This is a really cool machine.
