I think the integrated video card should give you a hint that this is not good for them. You may play casual games such as LOL or Genshin Impact or Valorant/CS, but expect poor framerates.

Hey bro but it has the RTX 4050 6gb DDR6? What's going on?😟

Thank you for your reply! As a matter of fact, Dos Shell was a rudimentary implementation of a task swapper, probably a part of the MultiDOS Microsoft was developing and ended. Microsoft did not want to continue this DOS branch as soon as Windows got more traction than expected, in the Win 3.0 timeframe.

Thank you for your reply and memories you shared! I fondly remember such toys. As far as I remember from all the consoles I had, I never saw this behavior in the snake game nor anywhere else. I am curious about one fact, though, I am not sure if it will be enough to have a rough idea of what may be wrong... Could you send a photo of the unit, if you still have it available, so I can more or less determine its vintage, please? These consoles certainly had their charm! I am sure few people would have experienced them if it was not for Tetris, in the early 1990s, and all the ingenuity in creating a highly affordable device. Of course, it was far from what the Gameboy and the likes allowed, but it was, for some, the only exposure they could have to this fantastic world!

Windows was a resource hog and had a highly inelegant design. OS/2 was a proof of what could be done but it had IBM as it helm and they were clueless as well as GUI blind. In the end, DOS lived much more than expected, particularly as PMODE Extenders created a decently scalable solution when resources were still scarce.

A very good observation! When published, the auto-captioning feature of RU-vid worked so badly it was disturbing. This is why I turned it off. I am sad you had difficulty understanding the video yet I wholly appreciate that you had the patience to see my long presentation! Thank you very much for your encouragement and support!

No, unfortunately, this is wrong, the issue is somewhere else! The adapter is active not passive! I took apart one adapter, long ago, and, buried in silicone, there is a very small board with a chip. There is a minor processing being done in the adapter, in spite of appearance. Due to the way the adapter is build, it probably cannot negotiate with more than a few peripherals.

My version has a fuse.

@@thebuggy736 Thank you for the detailed reply. The meter definitely has quality issues, and it should have been taken out of manufacturing, long ago. Minimal features such as the presence or not of a fuse should have been trivial. The soldering job is shoddy, probes are poor, just about everything is sub-par. A major letdown of most Chinese older analogue meters is that they never come calibrated, their readings are all over the place, it is like they do not even care. Sadly, they care where it does not matter, such as using SMD components on a board. Of course, the MF-47 does not have that, but other designs do. There is no optimization anywhere else, though, all the development budget dried out there. Even 20 years ago it was still obsolete and its accuracy is modest when compared to top of the line analogue meters that are still manufactured in China, by the way, and sold under different brands.

It is so inaccurate that even determining a voltage is sometimes hit and miss. I mean, when you are measuring a battery and have to sort through tens, the fractional voltage part starts to matter. Of course, if you really want a battery tester, it is fine, but it is not a multi-tester or multimeter and it is even quite expensive for what it is.

Yes, but don't expect it to work with most peripherals, as mentioned. It is built in a way that does not have a lot of hardware support or compatibility.

I am well aware of that, alkaline batteries have different characteristics. The issue was how much of a charge they can keep and how much current they deliver when new, as well as the variability in a specific batch. All of these indicate the quality you may expect and lifetime performance, compared with other batteries using the same technology, of course.

Unfortunately, such a drift is not acceptable and did not happen with other models, newer or older, from different manufacturers, even no name units, so there is clearly a design issue with these ultra compact ones. There is a grounding plan on the unit, as all handheld multimeters have, so I still consider it as a fault. It is funny that ANENG meters are also made in Guangdong (Shenzen) China, as are the UNI-T products, which makes it very interesting for cross-comparisons. On the surface, the AN101 is a comparable product, probably better built than the UT120C, but is seems to have similar flaws. In terms of being a True RMS meter, I highly doubt that it is accurate enough to qualify. The AN101 still has no internal fusing, so safety is not much better. Overall, yes AN101 is probably slightly better but that does not say much.

@@retrowikid Over the past few days I've paid attention to professional and personal test equipment, from Flukes to Keithleys to Anengs. Maybe I work and live in electrically noisy areas because they all drift or show offset. Connect the test leads together, it goes away, including my UT120C. Just read my Fluke manual which says "it is possible and normal for this and other true-rms meters to display non-zero readings when the test leads are disconnected from a circuit." Also so this behavior on some other RU-vid videos. So in my experience, a few hundredths of a volt showing in the display is normal when leads are dangling unterminated in a EMF or static generating environment, even on well shielded units. No, these aren't safe devices but they sure are amazingly well equipped and handy for low-power, low-voltage tasks.

Unfortunately, I see no easy solution. The issue seems to be the firmware or the logic that fails. This is why I scrapped my unit that had, as you guess, a very short life. I am sorry for you, as well.

The Aneng AOS02 seems to be better for a fraction of the price. I stopped to spend money just for a brand name. Unit is resting on its laurels as it seems.

Thank you very much!. The laptop is quite nice, the only design flaw I could notice is the keyboard. It was very good for running DOOM and other DOS games. No USB, the only way to attach something would be to use the parallel port, an adapter on PCMCIA for a CD-ROM drive, or simply swap the hard-drive and move it on another computer (there were 44 to 40 pin adapters for the IDE drive). On the topic of Windows 98, that is quite a challenge. Windows 95 OSR2 is the best operating system for a 486, albeit slightly slower than a Windows 3.11 or WFW. Windows 95 can run on 4MB of RAM but thrives on 16 or more. Windows 98 feels severely cramped in 16MB, so you need double that size. The CPU and particularly the Video chipset are totally unsuitable for the graphics load that Windows 98 puts it to. However, if you really needed compatibility with software, I admit, it was slightly better than Windows 95.

No, the laptop is long gone, we are talking about a couple of weeks past the video publishing date. Keep in mind that a newer version of the benchmark will not show a meaningful difference, it is just that some minor errors may not be present. If you know where to look, the CPU and GPU 2D/3D score are all that matter, it is not about specific performance/composition of the test.

@@retrowikid ah. did you return it? was there any problems with it?

@@noobienoob8977 No, it is much more easier than that. I prepare a system, test it, then it will be delivered to the intended user. I do not keep any device.

@@retrowikid hmm. Do you think it is a good device?

I think the laptop is quite compelling, particularly if you want a large 16 inch screen, good performance, expandability for RAM and storage, at this budget. In terms of battery life, it depends heavily on what you are doing. You can clearly reach 6 hours on a charge but heavy gaming/editing or other resource demanding activities will use up the battery quite quick. Also, keep in mind that what you achieve with a new battery will not be possible two or three years down the line, so it is good to be conservative.

Are there any alternatives with similar features at the price of 1250

@@noobienoob8977 As far as I researched with comparative offerings from Lenovo, there seems to be none. Asus may be an alternative, but I have not found a similar configuration with a 16 inch, 16:10 screen. If you want to look at Asus, their Vivobook Pro offerings with OLED screens are compelling, but you loose RAM expandability.

@@retrowikid hmm. i think i might get this laptop with a 4060

In america you can get the 4060 model for 1160 euros

Very interesting, thank you! I assumed there was an OEM that designed and manufactured for AT&T and others and it seems that it is quite similar to the Samsung Sens 700 you mentioned.

Although IBM was great, there are many great vintage laptops from Toshiba as well that are worth a look. Thank you for the comment and interest, I will keep it in mind!

@@retrowikidof course! And thank you.

@@BlueDippyI actually just came across one at a thrift store with a carry bag, charger, manuals, swappable floppy drive and CD drives and HDD. I’ll look at it again if you really want it to make sure it’s the one. It’s kinda how I ended up here. I wanted to see if I can play SNES or Genesis emulators on it

The battery does not work I’m pretty sure of that

@@SilverXTikal how much my man, and how damaged is it? I’d love it!

I cannot give a full evaluation on their long-term performance, as I use them sparingly, but, as it seems, they fare no worse than other mid-range rechargeable batteries (used them in flashlights, wireless mice, outdoors temperature wireless sensors). They are not probably on the same level as top-of-the-line products, but they are reliable enough.

​@@retrowikidagree, use them the same

Thank you very much, I really appreciate the detail comment. I agree that this UNI-T oscilloscope was poor and I was more surprised that there were premature failures on it. It is just as true that their multimeters are very good and I prefer them for their price/performance ratio. In fact, I think I still have one multimeter that has been in constant use for a decade and it still fares perfectly well. It is true, there is a problem on the board. Unfortunately, servicing is still difficult, as manufacturers do not care to make spare parts more widely available. Why is the contrast? I cannot give a definite answer but it may be that the platform they used was flawed, and this is a very good guess. Remember that no multimeter is actually their own design, most are second-sourced or reverse-engineered designs made by famous manufacturers such as Fluke and others. As a design is reverse-engineered, and the more complex it is, the higher the chances for a screw-up. When you take into account the "fame" of EEPROM poor designs that rewrite a tiny part of themselves on every initialization, there was a scandal on that years ago, you understand that oversight and a race to the bottom ends up with the results that you see. In the past, there were poor capacitors, recently, unreliably designed EEPROM and the future is unknown...

@@retrowikid I see what you mean and you sound convincing. In fact I even saw somewhere mentioned "the long term relationships of UNI-T and Fluke" - go figure what that actually means but your guess could be perfectly valid and it might translate into "UNI-T have been reverse engineering Fluke devices for quite awhile" :-) And yes - we should admit that at many attempts their reverse engineering was total success (if it really was the case). I hope you can still repair the device some day. I wish you luck on that! Take care.

Good afternoon! I would like to ask you please, how did the story with your oscilloscope end?

In case you have it installed, which I am not sure, the process is simple. However, note that it was taken out of the standard installation of DOS since version 6.22, and DOS 7.0/7.1 did not included it either. In case you have it available, just type dosshell and it should start the main executable from the main DOS directory.

The Romanian MF 35 equivalent is interesting. Judging by the specs, it seems to be highly similar to the MF 47. I do not know how well it was built internally, although I can assume there were some flaws. I would be curious to know how it fared out of the box, if it was properly calibrated or you had to fiddle with the pots before taking any accurate measurement. Another weak point of many analogue multimeters of the time were the probes, and I do not know how Mavo 35 stood in this respect. Many similar multimeters of that time did not have chrome plated probe tips, the plastic insulator was not particularly durable and you would frequently resort to improvisations to lengthen the service use. Surprisingly, the Mavo 35 is not shown to have had a high-voltage probe option for servicing the CRTs of the era. I also wonder how it fared in other safety respects as it seems to miss even the customary 250-500mA fuse on the low currents measuring range. As a general perspective, some electronics engineers and servicemen did appreciate more products from RFT and Tesla if they could not lend a hand on a western model. Soviet multimeters were rugged but had much poorer esthetics and usability so they were not that great of an option. I assume that build quality and precision where some of the reasons why the Mavo 35 was not favoured compared with other models of the era. Ultimately, the Mavo was a clone itself, and it was bound to have the same issues as the product that was the original inspiration. Another strange aspect is why the Mavo 35 design was not updated and was still manufactured as late as 1987, despite it being totally obsolete.

I do not understand what you mean by EMF. The UT33C+ is a more modern version but operates exactly the same as the old UT33C.

Thank you very much for your kind words. I know I presented very little about the device so please also visit this wonderful resource I found. I do not know Czech but I can attest that all the documentation is reliable. Perhaps you can use Google Translate and Lens to help with details. There are schematics and mechanical diagrams that will be really helpful: www.oldradio.cz/b4.htm I would like to mention that restoration is an ambitious project. There are two aspects that should receive particular attention. First of all, ensure that you can find replacement belts and good grease (a thicker, standard one for bushings, not the liquid type for precision mechanisms). Worn belts can be used only as a rough approximation for new purchases, since they are looser than they once were. Always treat with care contact points for playback-recording mode switches, they should be well cleaned. Potentiometers can work better if lubed with a drop of WD-40. The next aspect that matters is electronic components. Germanium Transistors were not as reliable as more modern Silicon transistors, and replacements may be more difficult to find. Expect old transistor technology to be "noisier". Electrolytic capacitors may be advisable to be replaced, but do not embark needlessly on this endeavour, unless you are certain it makes a difference. In the end, please also keep in mind that this mono reel-to-reel recorder did not provide a fantastic audio quality even when new so expectations should be adjusted. In many ways it was not even a semi-professional product. It worked well for its purpose, but not much beyond that. However, I entirely agree that making such a device operate will offer a lot of satisfaction. Good luck!
